Distributed Data Framework Documentation: Complete Documentation

Distributed Data Framework (DDF) is a free and open-source common data layer that abstracts services and business logic from underlying data structures to enable rapid integration of new data sources.

Licensed under LGPL This link is outside the DDF documentation , DDF is an interoperability platform that provides secure and scalable discovery and retrieval from a wide array of disparate sources.

DDF is:

a flexible and modular integration framework.
built to "unzip and run" even when scaled to large enterprise systems.
primarily focused on data integration, enabling clients to insert, query, and transform information from disparate data sources via the DDF Catalog.

1.2. Component Applications

DDF is comprised of several modular applications, to be installed or uninstalled as needed.

Admin Application: Enhances administrative capabilities when installing and managing DDF. It contains various services and interfaces that allow administrators more control over their systems.
Catalog Application: Provides a framework for storing, searching, processing, and transforming information. Clients typically perform local and/or federated query, create, read, update, and delete (QCRUD) operations against the Catalog. At the core of the Catalog functionality is the Catalog Framework, which routes all requests and responses through the system, invoking additional processing per the system configuration.
Platform Application: The Core application of the distribution. The Platform application contains the fundamental building blocks to run the distribution.
Security Application: Provides authentication, authorization, and auditing services for the DDF. It is both a framework that developers and integrators can extend and a reference implementation that meets security requirements.
Solr Catalog Application: Includes the Solr Catalog Provider, an implementation of the Catalog Provider using Apache Solr as a data store.
Spatial Application: Provides OGC services, such as CSW , WCS , WFS , and KML .
Search UI: Allows a user to search for records in the local Catalog (provider) and federated sources. Results of the search are returned and displayed on a globe or map, providing a visual representation of where the records were found.

3. Core Concepts

This introduction section is intended to give a high-level overview of the concepts and capabilities of DDF.

3.1. Introduction to Search

DDF provides the capability to search the Catalog for metadata. There are a number of different types of searches that can be performed on the Catalog, and these searches are accessed using one of several interfaces. This section provides a very high-level overview of introductory concepts of searching with DDF. These concepts are expanded upon in later sections.

Search Types

There are four basic types of metadata search. Additionally, any of the types can be combined to create a compound search.

Text Search: A text search is used when searching for textual information. It searches all textual fields by default, although it is possible to refine searches to a text search on a single metadata attribute. Text searches may use wildcards, logical operators, and approximate matches.
Spatial Search: A spatial search is used for Area of Interest (AOI) searches. Polygon and point radius searches are supported.
Temporal Search: A temporal search finds information from a specific time range. Two types of temporal searches are supported: relative and absolute. Relative searches contain an offset from the current time, while absolute searches contain a start and an end timestamp. Temporal searches can use the created or modified date attributes.
Datatype Search: A datatype search is used to search for metadata based on the datatype of the resource. Wildcards (*) can be used in both the datatype and version fields. Metadata that matches any of the datatypes (and associated versions if specified) will be returned. If a version is not specified, then all metadata records for the specified datatype(s) regardless of version will be returned.

3.2. Introduction to Metadata

In DDF, resources are the data products, files, reports, or documents of interest to users of the system.

Metadata is information about those resources, organized into a schema to make search possible. The Catalog stores this metadata and allows access to it. Metacards are single instances of metadata, representing a single resource, in the Catalog. Metacards follow one of several schemas to ensure reliable, accurate, and complete metadata. Essentially, Metacards function as containers of metadata.

3.3. Introduction to Ingest

Ingest is the process of bringing data products, metadata, or both into the catalog to enable search, sharing, and discovery. Ingested files are transformed into a neutral format that can be searched against as well as migrated to other formats and systems. See Ingesting Data for the various methods of ingesting data.

Upon ingest, a transformer will read the metadata from the ingested file and populate the fields of a metacard. Exactly how this is accomplished depends on the origin of the data, but most fields (except id) are imported directly.

3.4. Introduction to Resources

The Catalog Framework can interface with storage providers to provide storage of resources to specific types of storage, e.g., file system, relational database, XML database. A default file system implementation is provided by default.

Storage providers act as a proxy between the Catalog Framework and the mechanism storing the content. Storage providers expose the storage mechanism to the Catalog Framework. Storage plugins provide pluggable functionality that can be executed either immediately before or immediately after content has been stored or updated.

Storage providers provide the capability to the Catalog Framework to create, read, update, and delete resources in the content repository.

See Data Management for more information on specific file types supported by DDF.

3.5. Introduction to the Catalog Framework

The Catalog Framework wires all the Catalog components together.

It is responsible for routing Catalog requests and responses to the appropriate source, destination, federated system, etc.

Endpoints send Catalog requests to the Catalog Framework. The Catalog Framework then invokes Catalog Plugins, Transformers, and Resource Components as needed before sending requests to the intended destination, such as one or more Sources.

The Catalog Framework decouples clients from service implementations and provides integration points for Catalog Plugins and convenience methods for Endpoint developers.

3.6. Introduction to Federation and Sources

Federation is the ability of the DDF to query other data sources, including other DDFs. By default, the DDF is able to federate using OpenSearch and CSW protocols. The minimum configuration necessary to configure those federations is a query address.

Federation enables constructing dynamic networks of data sources that can be queried individually or aggregated into specific configuration to enable a wider range of accessibility for data and data products.

Federation provides the capability to extend the DDF enterprise to include Remote Sources, which may include other instances of DDF. The Catalog handles all aspects of federated queries as they are sent to the Catalog Provider and Remote Sources, as they are processed, and as the query results are returned. Queries can be scoped to include only the local Catalog Provider (and any Connected Sources), only specific Federated Sources, or the entire enterprise (which includes all local and Remote Sources). If the query is federated, the Catalog Framework passes the query to a Federation Strategy, which is responsible for querying each federated source that is specified. The Catalog Framework is also responsible for receiving the query results from each federated source and returning them to the client in the order specified by the particular federation strategy used. After the federation strategy handles the results, the Catalog returns them to the client through the Endpoint. Query results are returned from a federated query as a list of metacards. The source ID in each metacard identifies the Source from which the metacard originated.

3.7. Introduction to Events and Subscriptions

DDF can be configured to receive notifications whenever metadata is created, updated, or deleted in any federated sources. Creations, updates, and deletions are collectively called Events, and the process of registering to receive them is called Subscription.

The behavior of these subscriptions is consistent, but the method of configuring them is specific to the Endpoint used.

3.8. Introduction to Registries

The Registry Application serves as an index of registry nodes and their information, including service bindings, configurations and supplemental details.

Each registry has the capability to serve as an index of information about a network of registries which, in turn, can be used to connect across a network of DDFs and other data sources. Registries communicate with each other through the CSW endpoint and each registry node is converted into a registry metacard to be stored in the catalog. When a registry is subscribed to or published from, it sends the details of one or more nodes to another registry.

Identity Node: The Registry is initially comprised of a single registry node, refered to as the identity, which represents the registry’s primary configuration.
Subscription: Subscribing to a registry is the act of retreiving its information, specifically its identity information and any other registries it knows about. By default, subscriptions are configured to check for updates every 30 seconds.
Publication: Publishing is the act of sending a registry’s information to another registry. Once publication has occurred, any updates to the local registry will be pushed out to the registries that have been published to.

3.9. Introduction to Endpoints

Endpoints expose the Catalog Framework to clients using protocols and formats that the clients understand.

Endpoint interface formats encompass a variety of protocols, including (but not limited to):

SOAP Web services
RESTful services
JMS
JSON
OpenSearch

The endpoint may transform a client request into a compatible Catalog format and then transform the response into a compatible client format. Endpoints may use Transformers to perform these transformations. This allows an endpoint to interact with Source(s) that have different interfaces. For example, an OpenSearch Endpoint can send a query to the Catalog Framework, which could then query a federated source that has no OpenSearch interface.

Endpoints are meant to be the only client-accessible components in the Catalog.

3.10. Introduction to High Availability

DDF can be made highly available. In this context, High Availability is defined as the ability for DDF to be continuously operational with very little down time.

In a Highly Available Cluster, DDF has failover capabilities when a DDF node fails.

Note

The word "node", from a High Availability perspective, is one of the two DDF systems running within the Highly Available Cluster. Though there are multiple systems running with the Highly Available Cluster, it is still considered a single DDF from a user’s perspective or from other DDFs' perspectives.

This setup consists of a Solr Cloud instance, 2 DDF nodes connected to that Solr Cloud, and a failover proxy that sits in front of those 2 nodes. One of the DDF nodes will be arbitrarily chosen to be the active node, and the other will be the "hot standby" node. It is called a "hot standby" node because it is ready to receive traffic even though it’s not currently receiving any. The failover proxy will route all traffic to the active node. If the active node fails for any reason, the standby node will become active and the failover proxy will route all traffic to the new active node. See the below diagrams for more detail.

Highly Available Cluster

There are special procedures for initial setup and configuration of a highly available DDF. See High Availability Initial Setup and High Availability Configuration for those procedures.

4. Quick Start Tutorial

This quick tutorial will enable install, configuring and using a basic instance of DDF.

Note	This tutorial is intended for setting up a test, demonstration, or trial installation of DDF. For complete installation and configuration steps, see Installing.

These steps will demonstrate:

✓ Prerequisites.
✓ Quick Install of DDF.
✓ Ingesting Data.

4.1. Installing (Quick Start)

These are the basic requirements to set up the environment to run a DDF.

Warning

For security reasons, DDF cannot be started from a user’s home directory. If attempted, the system will automatically shut down.

4.1.1. Quick Install Prerequisites

Hardware Requirements (Quick Install)

At least 4096MB of memory for DDF.
- This amount can be increased to support memory-intensive applications. See Memory Considerations.

Java Requirements (Quick Install)

Follow the instructions outlined here: Java Requirements.

Warning

Check System Time

Prior to installing DDF, ensure the system time is accurate to prevent federation issues.

4.1.2. Quick Install of DDF

Download the DDF zip file .

Install DDF by unzipping the zip file.

Warning

Windows Zip Utility Warning

The Windows Zip implementation, which is invoked when a user double-clicks on a zip file in the Windows Explorer, creates a corrupted installation. This is a consequence of its inability to process long file paths. Instead, use the java jar command line utility to unzip the distribution (see example below) or use a third party utility such as 7-Zip.

Note: If and only if a JDK is installed, the jar command may be used; otherwise, another archiving utility that does not have issue with long paths should be installed

Use Java to Unzip in Windows(Replace <PATH_TO_JAVA> with correct path and <JAVA_VERSION> with current version.)

"<PATH_TO_JAVA>\jdk<JAVA_VERSION>\bin\jar.exe" xf ddf-2.21.6.zip

This will create an installation directory, which is typically created with the name and version of the application. This installation directory will be referred to as <DDF_HOME>. (Substitute the actual directory name.)
Start DDF by running the <DDF_HOME>/bin/ddf script (or ddf.bat on Windows).
Startup may take a few minutes.
1. Optionally, a system:wait-for-ready command (aliased to wfr) can be used to wait for startup to complete.
The Command Console will display.

Command Console Prompt

ddf@local>

4.1.3. Quick Install of DDF on a remote headless server

If DDF is being installed on a remote server that has no user interface, the hostname will need to be updated in the configuration files and certificates.

Note	Do not replace all instances of `localhost`, only those specified.

Configuring with a new hostname

Update the <DDF_HOME>/etc/custom.system.properties file. The entry org.codice.ddf.system.hostname=localhost should be updated to org.codice.ddf.system.hostname=<HOSTNAME>.
Update the <DDF_HOME>/etc/users.properties file. Change the localhost=localhost[…] entry to <HOSTNAME>=<HOSTNAME>. (Keep the rest of the line as is.)
Update the <DDF_HOME>/etc/users.attributes file. Change the "localhost" entry to "<HOSTNAME>".
From the console go to <DDF_HOME>/etc/certs and run the appropriate script.
1. *NIX: sh CertNew.sh -cn <hostname> -san "DNS:<hostname>".
2. Windows: CertNew -cn <hostname> -san "DNS:<hostname>".
Proceed with starting the system and continue as usual.

Configuring with an IP address

Update the <DDF_HOME>/etc/custom.system.properties file. The entry org.codice.ddf.system.hostname=localhost should be updated to org.codice.ddf.system.hostname=<IP>.
Update the <DDF_HOME>/etc/users.properties file. Change the localhost=localhost[…] entry to <IP>=<IP>. (Keep the rest of the line as is.)
Update the <DDF_HOME>/etc/users.attributes file. Change the "localhost" entry to "<IP>".
From the console go to <DDF_HOME>/etc/certs and run the appropriate script.
1. *NIX: sh CertNew.sh -cn <IP> -san "IP:<IP>".
2. Windows: CertNew -cn <IP> -san "IP:<IP>".
Proceed with starting the system and continue as usual.

Note

File Descriptor Limit on Linux

For Linux systems, increase the file descriptor limit by editing /etc/sysctl.conf to include:

fs.file-max = 6815744

(This file may need permissions changed to allow write access).
For the change to take effect, a restart is required.
1. *nix Restart Command

init 6

4.2. Certificates (Quick Start)

DDF comes with a default keystore that contains certificates. This allows the distribution to be unzipped and run immediately. If these certificates are sufficient for testing purposes, proceed to Configuring (Quick Start).

To test federation using 2-way TLS, the default keystore certificates will need to be replaced, using either the included Demo Certificate Authority or by Creating Self-signed Certificates.

If the installer was used to install the DDF and a hostname other than "localhost" was given, the user will be prompted to upload new trust/key stores.

If the hostname is localhost or, if the hostname was changed after installation, the default certificates will not allow access to the DDF instance from another machine over HTTPS (now the default for many services). The Demo Certificate Authority will need to be replaced with certificates that use the fully-qualified hostname of the server running the DDF instance.

4.2.1. Demo Certificate Authority (CA)

DDF comes with a populated truststore containing entries for many public certificate authorities, such as Go Daddy and Verisign. It also includes an entry for the DDF Demo Root CA. This entry is a self-signed certificate used for testing. It enables DDF to run immediately after unzipping the distribution. The keys and certificates for the DDF Demo Root CA are included as part of the DDF distribution. This entry must be removed from the truststore before DDF can operate securely.

4.2.1.1. Creating New Server Keystore Entry with the CertNew Scripts

To create a private key and certificate signed by the Demo Certificate Authority, use the provided scripts. To use the scripts, run them out of the <DDF_HOME>/etc/certs directory.

*NIX Demo CA Script

For *NIX, use the CertNew.sh script.

sh CertNew.sh [-cn <cn>|-dn <dn>] [-san <tag:name,tag:name,…>]

where:

<cn> represents a fully qualified common name (e.g. "<FQDN>", where <FQDN> could be something like cluster.yoyo.com)
<dn> represents a distinguished name as a comma-delimited string (e.g. "c=US, st=California, o=Yoyodyne, l=San Narciso, cn=<FQDN>")
<tag:name,tag:name,…> represents optional subject alternative names to be added to the generated certificate (e.g. "DNS:<FQDN>,DNS:node1.<FQDN>,DNS:node2.<FQDN>"). The format for subject alternative names is similar to the OpenSSL X509 configuration format. Supported tags are:
- email - email subject
- URI - uniformed resource identifier
- RID - registered id
- DNS - hostname
- IP - ip address (V4 or V6)
- dirName - directory name

If no arguments specified on the command line, hostname -f is used as the common-name for the certificate.

Windows Demo CA Script

For Windows, use the CertNew.cmd script.

CertNew (-cn <cn>|-dn <dn>) [-san "<tag:name,tag:name,…>"]

where:

<cn> represents a fully qualified common name (e.g. "<FQDN>", where <FQDN> could be something like cluster.yoyo.com)
<dn> represents a distinguished name as a comma-delimited string (e.g. "c=US, st=California, o=Yoyodyne, l=San Narciso, cn=<FQDN>")
<tag:name,tag:name,…> represents optional subject alternative names to be added to the generated certificate (e.g. "DNS:<FQDN>,DNS:node1.<FQDN>,DNS:node2.<FQDN>"). The format for subject alternative names is similar to the OpenSSL X509 configuration format. Supported tags are:
- email - email subject
- URI - uniformed resource identifier
- RID - registered id
- DNS - hostname
- IP - ip address (V4 or V6)
- dirName - directory name

The CertNew scripts:

Create a new entry in the server keystore.
Use the hostname as the fully qualified domain name (FQDN) when creating the certificate.
Adds the specified subject alternative names if any.
Use the Demo Certificate Authority to sign the certificate so that it will be trusted by the default configuration.

To install a certificate signed by a different Certificate Authority, see Managing Keystores.

After this proceed to Updating Settings After Changing Certificates.

Warning

If the server’s fully qualified domain name is not recognized, the name may need to be added to the network’s DNS server.

4.2.1.2. Dealing with Lack of DNS

In some cases DNS may not be available and the system will need to be configured to work with IP addresses.

Options can be given to the CertNew Scripts to generate certs that will work in this scenario.

*NIX

From <DDF_HOME>/etc/certs/ run:

sh CertNew.sh -cn <IP> -san "IP:<IP>"

Windows

From <DDF_HOME>/etc/certs/ run:

CertNew -cn <IP> -san "IP:<IP>"

After this proceed to Updating Settings After Changing Certificates, and be sure to use the IP address instead of the FQDN.

4.2.2. Creating Self-Signed Certificates

If using the Demo CA is not desired, DDF supports creating self-signed certificates with a self-signed certificate authority. This is considered an advanced configuration.

Creating self-signed certificates involves creating and configuring the files that contain the certificates. In DDF, these files are generally Java Keystores (jks) and Certificate Revocation Lists (crl). This includes commands and tools that can be used to perform these operations.

For this example, the following tools are used:

openssl
- Windows users can use: openssl for windows.
The standard Java keytool certificate management utility.
Portecle can be used for keytool operations if a GUI if preferred over a command line interface.

4.2.2.1. Creating a custom CA Key and Certificate

The following steps demonstrate creating a root CA to sign certificates.

Create a key pair.
$> openssl genrsa -aes128 -out root-ca.key 1024
Use the key to sign the CA certificate.
$> openssl req -new -x509 -days 3650 -key root-ca.key -out root-ca.crt

4.2.2.2. Sign Certificates Using the custom CA

The following steps demonstrate signing a certificate for the tokenissuer user by a CA.

Generate a private key and a Certificate Signing Request (CSR).
$> openssl req -newkey rsa:1024 -keyout tokenissuer.key -out tokenissuer.req
Sign the certificate by the CA.
$> openssl ca -out tokenissuer.crt -infiles tokenissuer.req

These certificates will be used during system configuration to replace the default certificates.

4.2.3. Updating Settings After Changing Certificates

After changing the certificates it will be necessary to update the system user and the org.codice.ddf.system.hostname property with the value of either the FQDN or the IP.

FQDNs should be used wherever possible. In the absence of DNS, however, IP addresses can be used.

Replace localhost with the FQDN or the IP in <DDF_HOME>/etc/users.properties, <DDF_HOME>/etc/users.attributes, and <DDF_HOME>/etc/custom.system.properties.

Tip	On linux this can be accomplished with a single command: `sed -i 's/localhost/<FQDN\|IP>/g' <DDF_HOME>/etc/users.* <DDF_HOME>/etc/custom.system.properties`

Finally, restart the DDF instance. Navigate to the Admin Console to test changes.

4.3. Configuring (Quick Start)

Set the configurations needed to run DDF.

In a browser, navigate to the Admin Console at https://{FQDN}:{PORT}/admin.
1. The Admin Console may take a few minutes to start up.
Enter the default username of admin and the password of admin.
Follow the installer prompts for a standard installation.
1. Click start to begin the setup process.
2. Configure guest claims attributes or use defaults.
  1. See Configuring Guest Access for more information about the Guest user.
  2. All users will be automatically granted these permissions.
  3. Guest users will not be able to ingest data with more restrictive markings than the guest claims.
  4. Any data ingested that has more restrictive markings than these guest claims will not be visible to Guest users.
3. Select Standard Installation.
  1. This step may take several minutes to complete.
4. On the System Configuration page, configure any port or protocol changes desired and add any keystores/truststores needed.
  1. See Certificates (Quick Start) for more details.
5. Click Next
6. Click Finish

4.4. Ingesting (Quick Start)

Now that DDF has been configured, ingest some sample data to demonstrate search capabilities.

This is one way to ingest into the catalog, for a complete list of the different methods, see Ingesting Data.

4.4.1. Ingesting Sample Data

Download a sample valid GeoJson file here .
Navigate in the browser to Intrigue at https://{FQDN}:{PORT}/search/catalog.
Select the Menu icon () in the upper left corner
Select Upload.
Drag and drop the sample file or click to navigate to it.
Select Start to begin upload.

Note	XML metadata for text searching is not automatically generated from GeoJson fields.

Querying from Intrigue (https://{FQDN}:{PORT}/search/catalog) will return the record for the file ingested:

Select the Menu icon ()and return to Workspaces.
Search for the ingested data.

Note	The sample data was selected as an example of well-formed metadata. Other data can and should be used to test other usage scenarios.

Managing

Administrators will be installing, maintaining, and supporting existing applications. Use this section to prepare, install, configure, run, and monitor a DDF.

5. Securing

Security is an important consideration for DDF, so it is imperative to update configurations away from the defaults to unique, secure settings.

Important

Securing DDF Components

DDF is enabled with an Insecure Defaults Service which will warn users/admins if the system is configured with insecure defaults.

A banner is displayed on the admin console notifying "The system is insecure because default configuration values are in use."

A detailed view is available of the properties to update.

Security concerns will be highlighted in the configuration sections to follow.

5.1. Security Hardening

Security Hardening

To harden DDF, extra security precautions are required.

Where available, necessary migitations to harden an installation of DDF are called out in the following configuration steps.

Refer to the Hardening Checklist for a compilation of these mitigations.

Note	The security precautions are best performed as configuration is taking place, so hardening steps are integrated into configuration steps.

This is to avoid setting an insecure configuration and having to revisit during hardening. Most configurations have a security component to them, and important considerations for hardening are labeled as such during configuration as well as provided in a checklist format.

Some of the items on the checklist are performed during installation and others during configuration. Steps required for hardening are marked as Required for Hardening and are collected here for convenience. Refer to the checklist during system setup.

5.2. Auditing

Required Step for Security Hardening

Audit logging captures security-specific system events for monitoring and review. DDF provides an Audit Plugin that logs all catalog transactions to the security.log. Information captured includes user identity, query information, and resources retrieved.

Follow all operational requirements for the retention of the log files. This may include using cryptographic mechanisms, such as encrypted file volumes or databases, to protect the integrity of audit information.

Note	The Audit Log default location is `<DDF_HOME>/data/log/security.log`

Note

Audit Logging Best Practices

For the most reliable audit trail, it is recommended to configure the operational environment of the DDF to generate alerts to notify adminstrators of:

auditing software/hardware errors
failures in audit capturing mechanisms
audit storage capacity (or desired percentage threshold) being reached or exceeded.

Warning

The security audit logging function does not have any configuration for audit reduction or report generation. The logs themselves could be used to generate such reports outside the scope of DDF.

5.2.1. Enabling Fallback Audit Logging

Required Step for Security Hardening

In the event the system is unable to write to the security.log file, DDF must be configured to fall back to report the error in the application log:

edit <DDF_HOME>/etc/org.ops4j.pax.logging.cfg
- uncomment the line (remove the # from the beginning of the line) for log4j2 (org.ops4j.pax.logging.log4j2.config.file = ${karaf.etc}/log4j2.xml)
- delete all subsequent lines

If you want to change the location of your systems security backup log from the default location: <DDF_HOME>/data/log/securityBackup.log, follow the next two steps:

edit <DDF_HOME>/security/configurations.policy
- find "Security-Hardening: Backup Log File Permissions"
- below grant codeBase "file:/pax-logging-log4j2" add the path to the directory containing the new log file you will create in the next step.
edit <DDF_HOME>/etc/log4j2.xml
- find the entry for the securityBackup appender. (see example)
- change value of filename and prefix of filePattern to the name/path of the desired failover security logs

  <RollingFile name="securityBackup" append="true" ignoreExceptions="false"
                     fileName="${sys:karaf.log}/securityBackup.log"
                     filePattern="${sys:karaf.log}/securityBackup.log-%d{yyyy-MM-dd-HH}-%i.log.gz">

                     fileName="<NEW_LOG_FILE>"
                     filePattern="<NEW_LOG_FILE>-%d{yyyy-MM-dd-HH}-%i.log.gz">

Warning

If the system is unable to write to the security.log file on system startup, fallback logging will be unavailable. Verify that the security.log file is properly configured and contains logs before configuring a fall back.

6. Installing

Set up a complete, secure instance of DDF. For simplified steps used for a testing, development, or demonstration installation, see the DDF Quick Start.

Important

Although DDF can be installed by any user, it is recommended for security reasons to have a non-root user execute the DDF installation.

Note	Hardening guidance assumes a Standard installation. Adding other components does not have any security/hardening implications.

6.1. Installation Prerequisites

Warning

For security reasons, DDF cannot be started from a user’s home directory. If attempted, the system will automatically shut down.

These are the system/environment requirements to configure prior to an installation.

Note	The DDF process or user under which the DDF process runs must have permission to create and write files in the directories where the Solr cores are installed, If this permission is missing, DDF will not be able to create new Solr cores and the system will not function correctly.

6.1.1. Hardware Requirements

6.2. Installing With the DDF Distribution Zip

Warning

Check System Time

Prior to installing DDF, ensure the system time is accurate to prevent federation issues.

To install the DDF distribution zip, perform the following:

Download the DDF zip file .
After the prerequisites have been met, change the current directory to the desired install directory, creating a new directory if desired. This will be referred to as <DDF_HOME>.

Warning

Windows Pathname Warning

Do not use spaces in directory or file names of the <DDF_HOME> path. For example, do not install in the default Program Files directory.
Example: Create a Directory (Windows and *NIX)
```
mkdir new_installation
```
1. Use a Non-root User on *NIX. (Windows users skip this step)
  
  It is recommended that the root user create a new install directory that can be owned by a non-root user (e.g., DDF_USER). This can be a new or existing user. This DDF_USER can now be used for the remaining installation instructions.
2. Create a new group or use an existing group (e.g., DDF_GROUP) (Windows users skip this step)
  Example: Add New Group on *NIX
  groupadd DDF_GROUP
  Example: Switch User on *NIX
  chown DDF_USER:DDF_GROUP new_installation su - DDF_USER
Change the current directory to the location of the zip file (ddf-2.21.6.zip).
*NIX (Example assumes DDF has been downloaded to a CD/DVD)
```
cd /home/user/cdrom
```
Windows (Example assumes DDF has been downloaded to the D drive)
```
cd D:\
```

Copy ddf-2.21.6.zip to <DDF_HOME>.

*NIX

cp ddf-2.21.6.zip <DDF_HOME>

Windows

copy ddf-2.21.6.zip <DDF_HOME>

Change the current directory to the desired install location.
*NIX or Windows
```
cd <DDF_HOME>
```

The DDF zip is now located within the <DDF_HOME>. Unzip ddf-2.21.6.zip.

*NIX

unzip ddf-2.21.6.zip

Warning

Windows Zip Utility Warning

Use Java to Unzip in Windows(Replace <PATH_TO_JAVA> with correct path and <JAVA_VERSION> with current version.)

"<PATH_TO_JAVA>\jdk<JAVA_VERSION>\bin\jar.exe" xf ddf-2.21.6.zip

The unzipping process may take time to complete. The command prompt will stop responding to input during this time.

6.2.1. Configuring Operating Permissions and Allocations

Restrict access to sensitive files by ensuring that the only users with access privileges are administrators.

Within the <DDF_HOME>, a directory is created named ddf-2.21.6. This directory will be referred to in the documentation as <DDF_HOME>.

Do not assume the deployment is from a trusted source; verify its origination.
Check the available storage space on the system to ensure the deployment will not exceed the available space.
Set maximum storage space on the <DDF_HOME>/deploy and <DDF_HOME>/system directories to restrict the amount of space used by deployments.

6.2.1.1. Setting Directory Permissions

Required Step for Security Hardening

DDF relies on the Directory Permissions of the host platform to protect the integrity of the DDF during operation. System administrators MUST perform the following steps prior to deploying bundles added to the DDF.

Important

The system administrator must restrict certain directories to ensure that the application (user) cannot access restricted directories on the system. For example the DDFUSER should have read-only access to <DDF_HOME>, except for the sub-directories etc, data, solr and instances.

Setting Directory Permissions on Windows

Set directory permissions on the <DDF_HOME>; all sub-directories except etc, data, and instances; and any directory intended to interact with the DDF to protect from unauthorized access.

Right-click on the <DDF_HOME> directory.
Select Properties → Security → Advanced.
Under Owner, select Change.
Enter Creator Owner into the Enter the Object Name… field.
Select Check Names.
Select Apply.
1. If prompted Do you wish to continue, select Yes.
Remove all Permission Entries for any groups or users with access to <DDF_HOME> other than System, Administrators, and Creator Owner.
1. Note: If prompted with a message such as: You can’t remove X because this object is inheriting permissions from its parent. when removing entries from the Permission entries table:
  1. Select Disable Inheritance.
  2. Select Convert Inherited Permissions into explicit permissions on this object.
  3. Try removing the entry again.
Select the option for Replace all child object permission entries with inheritable permission entries from this object.
Close the Advanced Security Settings window.

Setting Directory Permissions on *NIX

Set directory permissions to protect the DDF from unauthorized access.

Change ownership of <DDF_HOME>
- chown -R ddf-user <DDF_HOME>
Create instances sub-directory if does not exist
- mkdir -p <DDF_HOME>/instances
Change group ownership on sub-directories
- chgrp -R DDFGROUP <DDF_HOME>/etc <DDF_HOME>/data <DDF_HOME>/instances <DDF_HOME>/solr
Change group permissions
- chmod -R g-w <DDF_HOME>/etc <DDF_HOME>/data <DDF_HOME>/instances <DDF_HOME>/solr
Remove permissions for other users
- chmod -R o-rwx <DDF_HOME>/etc <DDF_HOME>/data <DDF_HOME>/instances

6.2.1.2. Configuring Memory Allocation for the DDF Java Virtual Machine

The amount of memory allocated to the Java Virtual Machine host DDF by the operating system can be increased by updating the setenv script:

Setenv Scripts: *NIX

<DDF_HOME>/bin/setenv
Update the JAVA_OPTS -Xmx value
<DDF_HOME>/bin/setenv-wrapper.conf
Update the wrapper.java.additional -Xmx value

Setenv Scripts: Windows

<DDF_HOME>/bin/setenv.bat
Update the JAVA_OPTS -Xmx value
<DDF_HOME>/bin/setenv-windows-wrapper.conf
Update the wrapper.java.additional -Xmx value

6.2.1.3. Enabling JMX

By default, DDF prevents connections to JMX because the system is more secure when JMX is not enabled. However, many monitoring tools require a JMX connection to the Java Virtual Machine. To enable JMX, update the setenv script:

Setenv Scripts: *NIX

<DDF_HOME>/bin/setenv
Remove -XX:+DisableAttachMechanism from JAVA_OPTS
<DDF_HOME>/bin/setenv-wrapper.conf
Comment out the -XX:+DisableAttachMechanism line and re-number remainder lines appropriately

Setenv Scripts: Windows

<DDF_HOME>/bin/setenv.bat
Remove -XX:+DisableAttachMechanism from JAVA_OPTS
<DDF_HOME>/bin/setenv-windows-wrapper.conf
Comment out the -XX:+DisableAttachMechanism line and re-number remainder lines appropriately

6.2.1.4. Configuring Memory for the Solr Server

Note	This section applies only to configurations that manage the lifecycle of the Solr server. It does not apply to Solr Cloud configurations.

The Solr server consumes large amount of memory when it ingests documents. If the Solr server runs out of memory, it terminates its process. To allocate more memory to the Solr server, increase the value of the solr.mem property.

6.2.2. Managing Keystores and Certificates

Required Step for Security Hardening

DDF uses certificates in two ways:

Ensuring the privacy and integrity of messages sent or received over a network.
Authenticating an incoming user request.

To ensure proper configuration of keystore, truststore, and certificates, follow the options below according to situation.

Configuring Certificates Workflow

Jump to the steps referenced in the diagram:

Certificate Workflow Steps

Adding an Existing Keystore
Creating a New Keystore/Truststore with an Existing Certificate and Private Key
Adding an Existing Truststore
Creating a Server Keystore
1. Creating a Server Truststore

6.2.2.1. Managing Keystores

Certificates, and sometimes their associated private keys, are stored in keystore files. DDF includes two default keystore files, the server key store and the server trust store. The server keystore holds DDF’s certificate and private key. It will also hold the certificates of other nodes whose signature DDF will accept. The truststore holds the certificates of nodes or other entities that DDF needs to trust.

Note	Individual certificates of other nodes should be added to the keystore instead of CA certificates. If a CA’s certificate is added, DDF will automatically trust any certificate that is signed by that CA.

6.2.2.1.1. Adding an Existing Server Keystore

If provided an existing keystore for use with DDF, follow these steps to replace the default keystore.

Remove the default keystore at etc/keystores/serverKeystore.jks.
Add the desired keystore file to the etc/keystores directory.
Edit custom.system.properties file to set filenames and passwords.
1. If using a type of keystore other than jks (such as pkcs12), change the javax.net.ssl.keyStoreType property as well.
If the truststore has the correct certificates, restart server to complete configuration.
1. If provided with an existing server truststore, continue to Adding an Existing Server Truststore.
2. Otherwise, create a server truststore.

6.2.2.1.2. Adding an Existing Server Truststore

Remove the default truststore at etc/keystores/serverTruststore.jks.
Add the desired truststore file to the etc/keystores directory.
Edit custom.system.properties file to set filenames and passwords.
1. If using a type of truststore other than jks (such as pkcs12), change the javax.net.ssl.trustStoreType property as well.

If the provided server keystore does not include the CA certificate that was used to sign the server’s certificate, add the CA certificate into the serverKeystore file.

6.2.2.1.3. Creating a New Keystore/Truststore with an Existing Certificate and Private Key

If provided an existing certificate, create a new keystore and truststore with it.

Note	DDF requires that the keystore contains both the private key and the CA.

Using the private key, certificate, and CA certificate, create a new keystore containing the data from the new files.

cat client.crt >> client.key
openssl pkcs12 -export -in client.key -out client.p12
keytool -importkeystore -srckeystore client.p12 -destkeystore serverKeystore.jks -srcstoretype pkcs12 -alias 1
keytool -changealias -alias 1 -destalias client -keystore serverKeystore.jks
keytool -importcert -file ca.crt -keystore serverKeystore.jks -alias "ca"
keytool -importcert -file ca-root.crt -keystore serverKeystore.jks -alias "ca-root"

Create the truststore using only the CA certificate. Based on the concept of CA signing, the CA should be the only entry needed in the truststore.

keytool -import -trustcacerts -alias "ca" -file ca.crt -keystore truststore.jks
keytool -import -trustcacerts -alias "ca-root" -file ca-root.crt -keystore truststore.jks

Create a PEM file using the certificate, as some applications require that format.

openssl x509 -in client.crt -out client.der -outform DER
openssl x509 -in client.der -inform DER -out client.pem -outform PEM

Important

The localhost certificate must be removed if using a system certificate.

6.2.2.1.4. Updating Key Store / Trust Store via the Admin Console

Certificates (and certificates with keys) can be managed in the Admin Console.

Navigate to the Admin Console.
Select the Security application.
Select the Certificates tab.
Add and remove certificates and private keys as necessary.
Restart DDF.

Important

The default trust store and key store files for DDF included in etc/keystores use self-signed certificates. Self-signed certificates should never be used outside of development/testing areas.

This view shows the alias (name) of every certificate in the trust store and the key store. It also displays if the entry includes a private key ("Is Key") and the encryption scheme (typically "RSA" or "EC").

This view allows administrators remove certificates from DDF’s key and trust stores. It also allows administrators to import certificates and private keys into the keystores with the "+" button. The import function has two options: import from a file or import over HTTPS. The file option accepts a Java Keystore file or a PKCS12 keystore file. Because keystores can hold many keys, the import dialog asks the administrator to provide the alias of the key to import. Private keys are typically encrypted and the import dialog prompts the administrator to enter the password for the private key. Additionally, keystore files themselves are typically encrypted and the dialog asks for the keystore ("Store") password.

The name and location of the DDF trust and key stores can be changed by editing the system properties files, etc/custom.system.properties. Additionally, the password that DDF uses to decrypt (unlock) the key and trust stores can be changed here.

Important

DDF assumes that password used to unlock the keystore is the same password that unlocks private keys in the keystore.

The location, file name, passwords and type of the server and trust key stores can be set in the custom.system.properties file:

Setting the Keystore and Truststore Java Properties

javax.net.ssl.keyStore=etc/keystores/serverKeystore.jks
javax.net.ssl.keyStorePassword=changeit
javax.net.ssl.trustStore=etc/keystores/serverTruststore.jks
javax.net.ssl.trustStorePassword=changeit
javax.net.ssl.keyStoreType=jks
javax.net.ssl.trustStoreType=jks

Note	If the server’s fully qualified domain name is not recognized, the name may need to be added to the network’s DNS server.

Tip

The DDF instance can be tested even if there is no entry for the FQDN in the DNS. First, test if the FQDN is already recognized. Execute this command:

ping <FQDN>

If the command responds with an error message such as unknown host, then modify the system’s hosts file to point the server’s FQDN to the loopback address. For example:

127.0.0.1 <FQDN>

Note

Changing Default Passwords

This step is not required for a hardened system.

The default password in custom.system.properties for serverKeystore.jks is changeit. This needs to be modified.
- ds-cfg-key-store-file: ../../keystores/serverKeystore.jks
- ds-cfg-key-store-type: JKS
- ds-cfg-key-store-pin: password
- cn: JKS
The default password in custom.system.properties for serverTruststore.jks is changeit. This needs to be modified.
- ds-cfg-trust-store-file: ../../keystores/serverTruststore.jks
- ds-cfg-trust-store-pin: password
- cn: JKS

6.3. Initial Startup

Run the DDF using the appropriate script.

*NIX

<DDF_HOME>/bin/ddf

Windows

<DDF_HOME>/bin/ddf.bat

The distribution takes a few moments to load depending on the hardware configuration.

Tip	To run DDF as a service, see Starting as a Service.

6.3.1. Verifying Startup

At this point, DDF should be configured and running with a Solr Catalog Provider. New features (endpoints, services, and sites) can be added as needed.

Verification is achieved by checking that all of the DDF bundles are in an Active state (excluding fragment bundles which remain in a Resolved state).

Note	It may take a few moments for all bundles to start so it may be necessary to wait a few minutes before verifying installation.

Execute the following command to display the status of all the DDF bundles:

View Status

ddf@local>list | grep -i ddf

Warning

Entries in the Resolved state are expected, they are OSGi bundle fragments. Bundle fragments are distinguished from other bundles in the command line console list by a field named Hosts, followed by a bundle number. Bundle fragments remain in the Resolved state and can never move to the Active state.

Example: Bundle Fragment in the Command Line Console

96 | Resolved |  80 | 2.10.0.SNAPSHOT | DDF :: Platform :: PaxWeb :: Jetty Config, Hosts: 90

After successfully completing these steps, the DDF is ready to be configured.

6.3.2. DDF Directory Contents after Installation and Initial Startup

During DDF installation, the major directories and files shown in the table below are created, modified, or replaced in the destination directory.

Table 12. DDF Directory Contents

`system`	Local bundle repository. Contains all of the JARs required by DDF, including third-party JARs.

6.3.3. Completing Installation

Upon startup, complete installation from either the Admin Console or the Command Console.

6.3.3.1. Completing Installation from the Admin Console

Upon startup, the installation can be completed by navigating to the Admin Console at https://{FQDN}:{PORT}/admin.

Warning

Internet Explorer 10 TLS Warning

Internet Exlorer 10 users may need to enable TLS 1.2 to access the Admin Console in the browser.

Enabling TLS1.2 in IE10

Go to Tools → Internet Options → Advanced → Settings → Security.
Enable TLS1.2.

Default user/password: admin/admin.

On the initial startup of the Admin Console, a series of prompts walks through essential configurations. These configurations can be changed later, if needed.

Click Start to begin.

Setup Types

DDF is pre-configured with several installation profiles.

Standard Installation: Recommended. Includes these applications by default:
- Admin
- Catalog
- Platform
- Security
- Solr Catalog
- Spatial
- Intrigue
Minimum Installation: Includes these applications for a minimum install:
- Admin
- Platform
- Security
Development: Includes all demo, beta, and experimental applications.

Configure Guest Claim Attributes Page

Setting the attributes on the Configure Guest Claim Attributes page determines the minimum claims attributes (and, therefore, permissions) available to a guest, or not signed-in, user.

To change this later, see Configuring Guest Claim Attributes.

System Configuration Settings

System Settings: Set hostname and ports for this installation.
Contact Info: Contact information for the point-of-contact or administrator for this installation.
Certificates: Add PKI certificates for the Keystore and Truststore for this installation.
- For a quick (test) installation, if the hostname/ports are not changed from the defaults, DDF includes self-signed certificates to use. Do not use in a working installation.
- For more advanced testing, on initial startup of the Admin Console append the string ?dev=true to the url (https://{FQDN}:{PORT}/admin?dev=true) to auto-generate self-signed certificates from a demo Certificate Authority(CA). This enables changing hostname and port settings during initial installation.
  - NOTE: ?dev=true generates certificates on initial installation only. Do not use in a working installation.
- For more information about importing certificate from a Certificate Authority, see Managing Keystores and Certificates.

Configure Single Sign On (SSO)

Configure Single Sign On method: SAML or OIDC.

SAML SSO

Enter the URLs for the IdP metatdata and set other options.

IdP Server

Configure $DDF’s internal Identity Provider Server.

SP Metadata: The metatada of the desired Service Provider to connect to the internal IdP. Can be configured as an HTTPS URL (https://), file URL (file:), or an XML block (<md:EntityDescriptor>…</md:EntityDescriptor>).
Require Signed AuthnRequests: Toggle whether or not to require signed AuthnRequests. When off, unsigned AuthnRequests will be rejected.
Limit RelayStates to 80 Bytes: Toggle whether or not to restrict the RelayState length to 80 bytes. The SAML specification requires a maximum length of 80 bytes. When on, messages with RelayStates over 80 bytes will be rejected. Only disable if this length is not enforced by the IdP being connected.
Cookie Expiration Time (minutes): Sets the cookie expiration time for Single Sign On, which determines how long the internal IdP will cache SAML assertions for later use. This value should match the lifetime of SAML assertions.

IdP Client

Configure handling of incoming requests where SAML authentication is enabled.

IdP Metadata: The metadata of the desired IdP to authenticate with. Can be configured as an HTTPS URL (https://), file URL (file:), or an XML block (<md:EntityDescriptor>…</md:EntityDescriptor>).
Perform User-Agent Check: If selected, this will allow clients that do not support ECP and are not browsers to fall back to PKI, BASIC, and potentially GUEST authentication, if enabled.

OIDC

Select the IdP type desired and set other options as needed.

OIDC Handler Configuration

Configurations relating to handling incoming requests where OIDC authentication is enabled.

IdP Type: The type of IdP that OIDC will be authenticating with.
Client ID: Unique ID for the client. This may be provided by the Identity Provider.

Finished Page

Upon successful startup, the Finish page will redirect to the Admin Console to begin further configuration, ingest, or federation.

Note	The redirect will only work if the certificates are configured in the browser. Otherwise the redirect link must be used.

6.3.3.2. Completing Installation from the Command Console

In order to install DDF from the Command Console, use the command profile:install <profile-name>. The <profile-name> should be the desired Setup Type in lowercase letters. To see the available profiles, use the command profile:list.

Note	This only installs the desired Setup Type. There are other components that can be set up in the Admin Console Installer that cannot be setup on the Command Console. After installing the Setup Type, these other components can be set up as described below.

6.3.3.2.1. Configuring Guest Claim Attributes

The Guest Claim Attributes can be configured via the Admin Console after running the profile:install command. See Configuring Guest Claim Attributes.

6.3.3.2.2. System Configuration Settings

System Settings and Contact Info, as described in System Configuration Settings, can be changed in <DDF_HOME>/etc/custom.system.properties. The certificates must be set up manually as described in Managing Keystores and Certificates.

Note	The system will need to be restarted after changing any of these settings.

6.3.4. Firewall Port Configuration

Below is a table listing all of the default ports that DDF uses and a description of what they are used for. Firewalls will need to be configured to open these ports in order for external systems to communicate with DDF.

Table 13. Port List
Port	Usage description
8993	https access to DDF admin and search web pages.
8101	For administering DDF instances gives ssh access to the administration console.
1099	RMI Registry Port
44444	RMI Server Port
8994	Solr Server Port. DDF does not listen on this port, but the Solr process does and it must be able to receive requests from DDF on this port.

Note	These are the default ports used by DDF. DDF can be configured to use different ports.

6.3.5. Internet Explorer 11 Enhanced Security Configuration

Below are steps listing all of the changes that DDF requires to run on Internet Explorer 11 and several additional considerations to keep in mind.

In the IE11 Settings > Compatibility View Settings dialog, un-check Display intranet sites in Compatibility View.
In the Settings > Internet Options > Security tab, Local intranet zone:
1. Click the Sites > Advanced button, add the current host name to the list, e.g., https://windows-host-name.domain.edu, and close the dialog.
2. Make sure the security level for the Local intranet zone is set to Medium-low in Custom level….
  1. Enable Protected Mode is checked by default, but it may need to be disabled if the above changes do not fully resolve access issues.
Restart the browser.

Note	During installation, make sure to use the host name and not localhost when setting up the DDF’s hostname, port, etc.

6.4. High Availability Initial Setup

This section describes how to complete the initial setup of DDF in a Highly Available Cluster.

Prerequisites

A failover proxy that can route HTTP traffic according to the pattern described in the Introduction to High Availability. It is recommended that a hardware failover proxy be used in a production environment.
Solr Cloud: See the Solr Cloud section for installation and configuration guidance to connect DDF nodes to Solr Cloud.

Once the prerequisites have been met, the below steps can be followed.

Note	Unless listed in the High Availability Initial Setup Exceptions section, the normal steps can be followed for installing, configuring, and hardening.

Install the first DDF node. See the Installation Section.
Configure the first DDF node. See the Configuring Section.
Optional: If hardening the first DDF node (excluding setting directory permissions). See the Hardening Section.
Export the first DDF node’s configurations, install the second DDF node, and import the exported configurations on that node. See Reusing Configurations.
If hardening, set directory permissions on both DDF nodes. See Setting Directory Permissions.

6.4.1. High Availability Initial Setup Exceptions

These steps are handled differently for the initial setup of a Highly Available Cluster.

6.4.1.1. Failover Proxy Integration

In order to integrate with a failover proxy, the DDF node’s system properties (in <DDF_HOME>/etc/custom.system.properties) must be changed to publish the correct port to external systems and users. This must be done before installing the first DDF node. See High Availability Initial Setup.

There are two internal port properties that must be changed to whatever ports the DDF will use on its system. Then there are two external port properties that must be changed to whatever ports the failover proxy is forwarding traffic through.

Warning

Make sure that the failover proxy is already running and forwarding traffic on the chosen ports before starting the DDF. There may be unexpected behavior otherwise.

In the below example, the failover proxy with a hostname of service.org is forwarding https traffic via 8993 and http traffic via 8181. The DDF node will run on 1111 for https and 2222 for http (on the host that it’s hosted on). The hostname of the DDF must match the hostname of the proxy.

org.codice.ddf.system.hostname=service.org
org.codice.ddf.system.httpsPort=1111
org.codice.ddf.system.httpPort=2222
org.codice.ddf.system.port=${org.codice.ddf.system.httpsPort}

org.codice.ddf.external.hostname=service.org
org.codice.ddf.external.httpsPort=8993
org.codice.ddf.external.httpPort=8181
org.codice.ddf.external.port=${org.codice.ddf.external.httpsPort}

6.4.1.2. Identical Directory Structures

The two DDF nodes need to be under identical root directories on their corresponding systems. On Windows, this means they must be under the same drive.

6.4.1.3. Highly Available Security Auditing

A third party tool will have to be used to persist the logs in a highly available manner.

Edit the <DDF_HOME>/etc/org.ops4j.pax.logging.cfg file to enable log4j2, following the steps in Enabling Fallback Audit Logging.
Then put the appropriate log4j2 appender in <DDF_HOME>/etc/log4j2.xml to send logs to the chosen third party tool. See Log4j Appenders .

6.4.1.4. Shared Storage Provider

The storage provider must be in a location that is shared between the two DDF nodes and must be highly available. If hardening the Highly Available Cluster, this shared storage provider must be trusted/secured. One way to accomplish this is to use the default Content File System Storage Provider and configure it to point to a highly available shared directory.

6.4.1.5. High Availability Certificates

Due to the nature of highly available environments, localhost is not suitable for use as a hostname to identify the DDF cluster. The default certificate that ships with the product uses localhost as the common name, so this certificate needs to be replaced. The following describes how to generate a certificate signed by the DDF Demo Certificate Authority that uses a proper hostname.

Note	This certificate, and any subsequent certificates signed by the Demo CA, are intended for testing purposes only, and should not be used in production.

Certificates need to have Subject Alternative Names (SANs) which will include the host for the failover proxy and for both DDF nodes. A certificate with SANs signed by the Demo CA can be obtained by navigating to <DDF_HOME>/etc/certs/ and, assuming the proxy’s hostname is service.org, running the following for UNIX operating systems:

./CertNew.sh -cn service.org -san "DNS:service.org"

or the following for Windows operating systems:

CertNew -cn service.org -san "DNS:service.org"

Note	Systems that use DDF version 2.11.4 or later will automatically get a DNS SAN entry matching the CN without the need to specify the `-san` argument to the `CertNew` command.

More customization for certs can be achieved by following the steps at Creating New Server Keystore Entry with the CertNew Scripts.

6.4.1.6. High Availability Installation Profile

Instead of having to manually turn features on and off, there is a High Availability installation profile. This profile will not show up in the UI Installer, but can be installed by executing profile:install ha on the command line instead of stepping through the UI Installer. This profile will install all of the High Availability supported features.

7. Configuring

DDF is highly configurable and many of the components of the system can be configured to use an included DDF implementation or replaced with an existing component of an integrating system.

Note	Configuration Requirements Because components can easily be installed and uninstalled, it’s important to remember that for proper DDF functionality, at least the Catalog API, one Endpoint, and one Catalog Framework implementation must be active.

Configuration Tools

DDF provides several tools for configuring the system. The Admin Console is a useful interface for configuring applications, their features, and important settings. Alternatively, many configurations can be updated through console commands entered into the Command Console. Finally, configurations are stored in configuration files within the <DDF_HOME> directory.

Configuration Outline

While many configurations can be set or changed in any order, for ease of use of this documentation, similar subjects have been grouped together sequentially.

See Keystores and certificates to set up the certificates needed for messaging integrity and authentication. Set up Users with security attributes, then configure data attribute handling, and finally, define the Security Policies that map between users and data and make decisions about access.

Connecting DDF to other data sources, including other instances of DDF is covered in the Configuring Federation section.

Lastly, see the Configuring for Special Deployments section for guidance on common specialized installations, such as fanout or multiple identical configurations.

7.1. Admin Console Tutorial

The Admin Console is the centralized location for administering the system. The Admin Console allows an administrator to configure and tailor system services and properties. The default address for the Admin Console is https://{FQDN}:{PORT}/admin.

System Settings Tab

The configuration and features installed can be viewed and edited from the System tab of the Admin Console.

Managing Federation in the Admin Console

It is recommended to use the Catalog App → Sources tab to configure and manage sites/sources.

Viewing Currently Active Applications from Admin Console

DDF displays all active applications in the Admin Console. This view can be configured according to preference. Either view has an > arrow icon to view more information about the application as currently configured.

Table 14. Admin Console Views
View	Description
Tile View	The first view presented is the Tile View, displaying all active applications as individual tiles.
List View	Optionally, active applications can be displayed in a list format by clicking the list view button.

Application Detailed View

Each individual application has a detailed view to modify configurations specific to that application. All applications have a standard set of tabs, although some apps may have additional ones with further information.

Table 15. Individual Application Views
Tab	Explanation
Configuration	The Configuration tab lists all bundles associated with the application as links to configure any configurable properties of that bundle.

Managing Features Using the Admin Console

DDF includes many components, packaged as features, that can be installed and/or uninstalled without restarting the system. Features are collections of OSGi bundles, configuration data, and/or other features.

Note	Transitive Dependencies Features may have dependencies on other features and will auto-install them as needed.

In the Admin Console, Features are found on the Features tab of the System tab.

Navigate to the Admin Console.
Select the System tab.
Select the Features tab.
Uninstalled features are shown with a play arrow under the Actions column.
1. Select the play arrow for the desired feature.
2. The Status will change from Uninstalled to Installed.
Installed features are shown with a stop icon under the Actions column.
1. Select the stop icon for the desired feature.
2. The Status will change from Installed to Uninstalled.

7.2. Console Command Reference

DDF provides access to a powerful Command Console to use to manage and configure the system.

7.2.1. Feature Commands

Individual features can also be added via the Command Console.

Determine which feature to install by viewing the available features on DDF.
ddf@local>feature:list
The console outputs a list of all features available (installed and uninstalled). A snippet of the list output is shown below (the versions may differ):

State         Version            Name                                     Repository                           Description

[uninstalled] [2.21.6         ] ddf-source-dummy              ddf-2.21.6

7.3. Configuration Files

Many important configuration settings are stored in the <DDF_HOME> directory.

Note	Depending on the environment, it may be easier for integrators and administrators to configure DDF using the Admin Console prior to disabling it for hardening purposes. The Admin Console can be re-enabled for additional configuration changes.

In an environment hardened for security purposes, access to the Admin Console or the Command Console might be denied and using the latter in such an environment may cause configuration errors. It is necessary to configure DDF (e.g., providers, Schematron rulesets, etc.) using .config files.

A template file is provided for some configurable DDF items so that they can be copied/renamed then modified with the appropriate settings.

Warning

If the Admin Console is enabled again, all of the configuration done via .config files will be loaded and displayed. However, note that the name of the .config file is not used in the Admin Console. Rather, a universally unique identifier (UUID) is added when the DDF item was created and displays this UUID in the console (e.g., OpenSearchSource.112f298e-26a5-4094-befc-79728f216b9b)

7.3.1. Configuring Global Settings with custom.system.properties

Global configuration settings are configured via the properties file custom.system.properties. These properties can be manually set by editing this file or set via the initial configuration from the Admin Console.

Note	Any changes made to this file require a restart of the system to take effect.

Important

The passwords configured in this section reflect the passwords used to decrypt JKS (Java KeyStore) files. Changing these values without also changing the passwords of the JKS causes undesirable behavior.

This variable version is more verbose, but will not need to be changed if the system host, port or root context changes.

Warning

Only root can access ports < 1024 on Unix systems.

7.3.2. Configuring with .config Files

The DDF is configured using .config files. Like the Karaf .cfg files, these configuration files must be located in the <DDF_HOME>/etc/ directory. Unlike the Karaf .cfg files, .config files must follow the naming convention that includes the configuration persistence ID (PID) that they represent. The filenames must be the pid with a .config extension. This type of configuration file also supports lists within configuration values (metatype cardinality attribute greater than 1) and String, Boolean, Integer, Long, Float, and Double values.

Important

This new configuration file format must be used for any configuration that makes use of lists. Examples include Web Context Policy Manager (org.codice.ddf.security.policy.context.impl.PolicyManager.config) and Guest Claims Configuration (ddf.security.guest.realm.config).

Warning

Only one configuration file should exist for any given PID. The result of having both a .cfg and a .config file for the same PID is undefined and could cause the application to fail.

The main purpose of the configuration files is to allow administrators to pre-configure DDF without having to use the Admin Console. In order to do so, the configuration files need to be copied to the <DDF_HOME>/etc directory after DDF zip has been extracted.

Upon start up, all the .config files located in <DDF_HOME>/etc are automatically read and processed. DDF monitors the <DDF_HOME>/etc directory for any new .config file that gets added. As soon as a new file is detected, it is read and processed. Changes to these configurations from the Admin Console or otherwise are persisted in the original configuration file in the <DDF_HOME>/etc directory.

7.4. Configuring User Access

DDF does not define accounts or types of accounts to support access. DDF uses an attribute based access control (ABAC) model. For reference, ABAC systems control access by evaluating rules against the attributes of the entities (subject and object), actions, and the environment relevant to a request.

DDF can be configured to access many different types of user stores to manage and monitor user access.

7.4.1. Configuring Guest Access

Unauthenticated access to a secured DDF system is provided by the Guest user. By default, DDF allows guest access.

Because DDF does not know the identity of a Guest user, it cannot assign security attributes to the Guest. The administrator must configure the attributes and values (i.e. the "claims") to be assigned to Guests. The Guest Claims become the default minimum attributes for every user, both authenticated and unauthenticated. Even if a user claim is more restrictive, the guest claim will grant access, so ensure the guest claim is only as permissive as necessary.

The Guest user is uniquely identified with a Principal name of the format Guest@UID. The unique identifier is assigned to a Guest based on its source IP address and is cached so that subsequent Guest accesses from the same IP address within a 30-minute window will get the same unique identifier. To support administrators' need to track the source IP Address for a given Guest user, the IP Address and unique identifier mapping will be audited in the security log.

Make sure that all the default logical names for locations of the security services are defined.

7.4.1.1. Denying Guest User Access

To disable guest access for a context, use the Web Context Policy Manager configuration to remove Guest. from the Authentication Type for that context. Only authorized users are then allowed to continue to the Search UI page.

Note	If using the included IdP for authentication, disable the `Allow Guest Access` option by Configuring the IdP Server.

7.4.1.2. Allowing Guest User Access

Guest authentication must be enabled and configured to allow guest users. Once the guest user is configured, redaction and filtering of metadata is done for the guest user the same way it is done for normal users.

To enable guest authentication for a context, use the Web Context Policy Manager configuration to select Allow Guest Access.

Navigate to the Admin Console.
Select the Security application.
Select the Configuration tab.
Select Web Context Policy Manager.
Select Allow Guest Access

7.4.1.2.1. Configuring Guest Interceptor if Allowing Guest Users

Required Step for Security Hardening

If a legacy client requires the use of the secured SOAP endpoints, the guest interceptor should be configured. Otherwise, the guest interceptor and public endpoints should be uninstalled for a hardened system.

To uninstall the guest interceptor and public endpoints: . Navigate to the Admin Console. . Select the System tab. . Open the Features section. . Search for security-interceptor-guest. . Click the Uninstall button.

7.4.1.2.2. Configuring Guest Claim Attributes

A guest user’s attributes define the most permissive set of claims for an unauthenticated user.

A guest user’s claim attributes are stored in configuration, not in the LDAP as normal authenticated users' attributes are.

Navigate to the Admin Console.
Select the Security application.
Select the Configuration tab.
Select the Security Guest Claims Handler.
Add any additional attributes desired for the guest user.
Save changes.

7.4.2. Configuring REST Services for Users

If using REST services or connecting to REST sources, several configuration options are available.

DDF includes an Identity Provider (IdP), but can also be configured to support an external IdP or no IdP at all. The following diagram shows the configuration options.

REST Services Configuration Options

7.4.2.1. Configuring Included Identity Provider

The included IdP is installed by default.

Installing the IdP from the Admin Console

Navigate to the Admin Console.
Select the System tab.
Select the Features tab.
Install security-idp feature.

Installing the IdP from the Command Console

Run the command feature:install security-idp from the Command Console.

Configuring the IdP Server

Navigate to the Admin Console.
Select the Security application.
Select the Configuration tab.
Select IdP Server.
Configure Authentication Request requirements
1. Disable the Require Signed AuthnRequests option to allow processing of authentication requests without signatures.
2. Disable the Limit RelayStates to 80 Bytes option to allow interoperability with Service Providers that are not compliant with the SAML Specifications and send RelayStates larger than 80 bytes.
Configure Guest Access:
1. Disable the Allow Guest Access option to disallow a user to authenticate against the IdP with a guest account.
Configure the Service Providers (SP) Metadata:
1. Select the + next to SP Metadata to add a new entry.
2. Populate the new entry with:
  1. an HTTPS URL (https://) such as https://localhost:8993/services/saml/sso/metadata1,
  2. a file URL (file:), or
  3. an XML block to refer to desired metadata.

Configuring Authentication Types to use SAML IdP

To use the SAML IdP for authentication,

Navigate to the Admin Console.
Select the Security application.
Select the Configuration tab.
Select Web Context Policy Manager.
Under Authentication Types, set the authentication type to SAML for context paths as necessary. For example:
- /search=SAML

Other authentication types can also be used in conjunction with the SAML type. For example, if you wanted to secure the entire system with the IdP, but still allow legacy clients that don’t understand the SAML ECP specification to connect, you could set /=SAML|PKI. With that configuration, any clients that failed to connect using either the SAML 2.0 Web SSO Profile or the SAML ECP specification would fall back to 2-way TLS for authentication.

Configuring the SP

To configure the IdP client (also known as the SP) that interacts with the specified IdP,

Navigate to the Admin Console.
Select the Security application.
Select the Configuration tab.
Select IdP Client.
Populate IdP Metadata field through one of the following:
1. an HTTPS URL (https://) e.g., https://localhost:8993/services/idp/login/metadata,
2. a file URL (file:), or
3. an XML block to refer to desired metadata.

When using the included IdP, DDF can be configured to use the included Security Token Service(STS).

7.4.2.1.1. Configuring Included STS

An LDAP server can be used to maintain a list of DDF users and the attributes associated with them. The Security Token Service (STS) can use an LDAP server as an attribute store and convert those attributes to SAML claims.

DDF includes a demo LDAP server, but an external LDAP is required for actual installation.

The STS is installed by default in DDF.

Configuring STS

Verify that the serverKeystores.jks file in <DDF_HOME>/etc/keystores trusts the hostnames used in your environment (the hostnames of LDAP, and any DDF users that make use of this STS server).
Navigate to the Admin Console.
Select the System tab.
Select the Features tab.
Start the security-sts-ldaplogin and security-sts-ldapclaimshandler features.
Select the Configuration tab.
Select the Security STS LDAP Login configuration.
Verify that the LDAP URL, LDAP Bind User DN, and LDAP Bind User Password fields match your LDAP server’s information.
1. The default DDF LDAP settings will match up with the default settings of the OpenDJ embedded LDAP server. Change these values to map to the location and settings of the LDAP server being used.
Select the Save changes button if changes were made.
Open the Security STS LDAP and Roles Claims Handler configuration.
Populate the same URL, user, and password fields with your LDAP server information.
Select the Save Changes button.

Configuring DDF Authentication Scheme

Configure the DDF to use this authentication scheme.

Navigate to the Admin Console.
Select the Catalog application.
Open the Web Context Policy Manager configuration.
1. Under Authentication Types, make any desired authentication changes to contexts.
  1. In order to use the SAML 2.0 Web SSO profile against a context, you must specify only the SAML authentication type.

Security STS Client

Configure the client connecting to the STS.

Navigate to the Admin Console.
Select the Security application.
Open the Security STS Client configuration.
Verify that the host/port information in the STS Address field points to your STS server. If you are using the default bundled STS, this information will already be correct.

See Security STS Client table for all configuration options.

The DDF should now use the SSO/STS/LDAP servers when it attempts to authenticate a user upon an attempted log in.

STS Server

Connect to the server hosting the STS.

Navigate to the Admin Console.
Select the Security application.
Select the Security STS Server configuration.
Verify the hostname and usernames are correct.

See Security STS Server table for all configuration options.

SAML Name ID

Set up alternatives to displaying the username of the logged in user.

Navigate to the Admin Console.
Select the Security application.
Select the SAML NameID Policy configuration.
Add any desired attributes to display instead of the username. (The first matching attribute will be used.)

Limiting Access to the STS

Be sure to limit the hosts that are allowed to connect to the STS:

Required Step for Security Hardening
Open the <DDF_HOME>/etc/custom.system.properties file.
Edit the line ws-security.subject.cert.constraints = .*CN=<MY_HOST_CN>.*.
- By default this will only allow your hostname. To allow other desired hosts add their CNs to the regular expression within parentheses delimited by |:
  - ws-security.subject.cert.constraints = .*CN=(<MY_HOST_CN>|<OTHER_HOST_CN>|<ANOTHER_HOST_CN>).*

Configuring OpenID Connect (OIDC) and OAuth 2.0

To use OpenID Connect (OIDC) and OAuth 2.0, DDF needs to be connected to an external Identity Provider (IdP) which supports these protocols.

OIDC

OIDC is used to authenticate (or log in) a user. To use this protocol in DDF, DDF needs the external IdP’s information.

To connect to an external IdP,

Navigate to the Admin Console.
Select the Security application.
Select the Configuration tab.
Select OIDC Handler Configuration.
Populate the fields with the external IdP’s information. For more detail, see the OIDC Handler Configuration section under Configure Single Sign On.

Once connected, the Web Context Policy Manager needs to be updated. to do so,

Under the Configuration tab in the Security application
Select the Web Context Policy Manager.
Under Authentication Types, add the context type of the endpoint you wish to protect with OIDC. For example /search=OIDC.

OAuth 2.0

OAuth 2.0 is an authorization protocol and DDF can use it when federating. When a user queries a source that is configured to use this protocol, DDF will forward the user’s information (access token) with the request. If a source can be configured to use OAuth 2.0, OAuth 2.0 will appear as an option under Authentication Type in the source’s configuration.

To configure a source to use OAuth 2.0, under the source’s configuration,

Change the Authentication Type to OAuth 2.0.
Set the OAuth Discovery Url to the discovery URL where the OAuth provider’s metadata is hosted.
Set the OAuth Client ID to the ID given to DDF when it was registered with the OAuth provider`.
Set the OAuth Client Secret to the secret given to DDF when it was registered with the OAuth provider`.
Set the OAuth Flow to the OAuth 2.0 flow to use when federating.

Note	If the system DDF is federating with is a DDF, the DDF receiving the federated request should be connected to an external IdP and have `/services` protected by that IdP (i.e. have /service=OIDC`).

7.4.2.2. Connecting to an External Identity Provider

To connect to an external Identity Provider,

Provide the external IdP with DDF’s Service Provider (SP) metadata. The SP metadata can found at https://<FQDN>:<PORT>/services/saml/sso/metadata.
Replace the IdP metadata field in DDF.
1. Navigate to the Admin Console.
2. Select the Security application.
3. Select the Configuration tab.
4. Select IdP Client.
5. Populate the IdP Metadata field with the external IdP’s metadata.

Note	The certificate that the external IdP uses for signing will need to be added to the DDF’s keystore. See Updating Key Store / Trust Store via the Admin Console for details.

Note	DDF may not interoperate successfully with all IdPs. To idenify the ones it can interoperate with use the The Security Assertion Markup Language (SAML) Conformance Test Kit (CTK)

Service Provider Metadata

It is not recommended to remove or replace the included Service Provider. To add an additional, external Service Provider, add the SP metadata to the IdP Server configuration. See Configuring Security IdP Service Provider for more detail.

7.4.2.3. Configuring Without an Identity Provider

To configure DDF to not use an Identity Provider (IdP),

Disable the IdP feature.
1. Navigate to the Admin Console.
2. Select the System tab.
3. Select the Features tab.
4. Uninstall the security-idp feature.
Change the Authentication Type if it is IdP.
1. Navigate to the Admin Console.
2. Select the Security application.
3. Select the Configuration tab.
4. Select Web Context Policy Manager
5. Under Authentication Types, remove the SAML authentication type from all context paths.

7.4.2.3.1. Using STS without IdP

To configure DDF to use the included Security Token Service (STS) without an IdP, follow the same Configuring STS steps, with one additional configuration to make via the Web Context Policy Manager.

Configuring Authentication Types for STS

Navigate to the Admin Console.
Select the Security application.
Select Configuration.
Select the Web Context Policy Manager.
Add any needed authentication types to the Authentication Types list, such as PKI, BASIC, etc.

7.4.2.4. Configuring Multi Factor Authentication

Mutli-factor authentication, sometimes referred to as two-factor authentication, allows for greater security. It does this by requiring users to provide multiple proofs of identity, typically through something they know (such as a password), and something they have/are (such as a randomly generated pin number sent to one of their personal devices). The IdP that comes with DDF does not support multi-factor authentication by default.

Keycloak can be used to help setup and configure multi-factor authentication. See Connecting to an External Identity Provider on how to initially hookup Keycloak.

Configuring Keycloak for MFA

Download and install Keycloak from here: Keycloak Downloads {external link}
See Choosing an Operating Mode {external link} to choose a specific operation mode.
Set up an Admin User following these steps here: Server Admin Initialization {external link}
Refer to OTP Policies {external link} for how to set up multi-factor authentication using supported authentication tools such as FreeOTP and Google Authenticator.

See the Keycloak Documentation {external link} for more information and details about how to configure Keycloack for multi-factor authentication.

7.4.3. Configuring SOAP Services for Users

If using SOAP services, DDF can be configured to use the included Security Token Service (STS).

7.4.3.1. Connecting to Included STS with SOAP

DDF includes a STS implementation that can be used for user authentication over SOAP services.

Configure the STS WSS

Configure the STS WSS.

Navigate to the Admin Console.
Select the Security application.
Select Configuration.
Select Security STS WSS.
Update the Claims that should be requested by the STS.

7.4.4. Connecting to an LDAP Server

Warning

The configurations for Security STS LDAP and Roles Claims Handler and Security STS LDAP Login contain plain text default passwords for the embedded LDAP, which is insecure to use in production.

Use the Encryption Service, from the Command Console to set passwords for your LDAP server. Then change the LDAP Bind User Password in the Security STS LDAP and Roles Claims Handler configurations to use the encrypted password.

A claim is an additional piece of data about a principal that can be included in a token along with basic token data. A claims manager provides hooks for a developer to plug in claims handlers to ensure that the STS includes the specified claims in the issued token.

Claims handlers convert incoming user credentials into a set of attribute claims that will be populated in the SAML assertion. For example, the LDAPClaimsHandler takes in the user’s credentials and retrieves the user’s attributes from a backend LDAP server. These attributes are then mapped and added to the SAML assertion being created. Integrators and developers can add more claims handlers that can handle other types of external services that store user attributes.

See the Security STS LDAP and Roles Claims Handler for all possible configurations.

7.4.5. Updating System Users

By default, all system users are located in the <DDF_HOME>/etc/users.properties and <DDF_HOME>/etc/users.attributes files. The default users included in these two files are "admin" and "localhost". The users.properties file contains username, password, and role information; while the users.attributes file is used to mix in additional attributes. The users.properties file must also contain the user corresponding to the fully qualified domain name (FQDN) of the system where DDF is running. This FQDN user represents this host system internally when making decisions about what operations the system is capable of performing. For example, when performing a DDF Catalog Ingest, the system’s attributes will be checked against any security attributes present on the metacard, prior to ingest, to determine whether or not the system should be allowed to ingest that metacard.

Additionally, the users.attributes file can contain user entries in a regex format. This allows an administrator to mix in attributes for external systems that match a particular regex pattern. The FQDN user within the users.attributes file should be filled out with attributes sufficient to allow the system to ingest the expected data. The users.attributes file uses a JSON format as shown below:


  1
2
3
4
5
6
7
8
9
10
11
12

  {
    "admin" : {
        "test" : "testValue",
        "test1" : [ "testing1", "testing2", "testing3" ]
    },
    "localhost" : {

    },
    ".*host.*" : {
        "reg" : "ex"
    }
}

For this example, the "admin" user will end up with two additional claims of "test" and "test1" with values of "testValue" and [ "testing1", "testing2", "testing3" ] respectively. Also, any host matching the regex ".host." would end up with the claim "reg" with the single value of "ex". The "localhost" user would have no additional attributes mixed in.

Warning

It is possible for a regex in users.attributes to match users as well as a system, so verify that the regex pattern’s scope will not be too great when using this feature.

Warning

If your data will contain security markings, and these markings are being parsed out into the metacard security attributes via a PolicyPlugin, then the FQDN user MUST be updated with attributes that would grant the privileges to ingest that data. Failure to update the FQDN user with sufficient attributes will result in an error being returned for any ingest request.

Warning

The following attribute values are not allowed:

null
""
a non-String (e.g. 100, false)
an array including any of the above
[]

Additionally, attribute names should not be repeated, and the order that the attributes are defined and the order of values within an array will be ignored.

7.4.6. Restricting Access to Admin Console

Required Step for Security Hardening

If you have integrated DDF with your existing security infrastructure, then you may want to limit access to parts of the DDF based on user roles/groups.

Limit access to the Admin Console to those users who need access. To set access restrictions on the Admin Console, consult the organization’s security architecture to identify specific realms, authentication methods, and roles required.

Navigate to the Admin Console.
Select the Security application.
Select the Configuration tab.
Select the Web Context Policy Manager.
1. A dialogue will pop up that allows you to edit DDF access restrictions.
2. Once you have configured your realms in your security infrastructure, you can associate them with DDF contexts.
3. If your infrastructure supports multiple authentication methods, they may be specified on a per-context basis.
4. Role requirements may be enforced by configuring the required attributes for a given context.
5. The white listed contexts allows child contexts to be excluded from the authentication constraints of their parents.

7.4.6.1. Restricting Feature, App, Service, and Configuration Access

Required Step for Security Hardening

Limit access to the individual applications, features, or services to those users who need access. Organizational requirements should dictate which applications are restricted and the extent to which they are restricted.

Navigate to the Admin Console.
Select the Admin application.
Select the Configuration tab.
Select the Admin Configuration Policy.
To add a feature or app permission:
1. Add a new field to "Feature and App Permissions" in the format of:
  
  <feature name>/<app name> = "attribute name=attribute value","attribute name2=attribute value2", …
2. For example, to restrict access of any user without an admin role to the catalog-app:
  
  catalog-app = "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/role=admin", …
To add a configuration permission:
1. Add a new field to "Configuration Permissions" in the format of:
  
  configuration id = "attribute name=attribute value","attribute name2=attribute value2", …
2. For example, to restrict access of any user without an admin role to the Web Context Policy Manager:
  
  org.codice.ddf.security.policy.context.impl.PolicyManager="http://schemas.xmlsoap.org/ws/2005/05/identity/claims/role=admin"

If a permission is specified, any user without the required attributes will be unable to see or modify the feature, app, or configuration.

7.4.7. Removing Default Users

Required Step for Security Hardening

The default security configuration uses a property file located at <DDF_HOME>/etc/users.properties to store users and passwords. A hardened system will remove this file and manage all users externally, via an LDAP server or by other means.

Note	Default Users are an Insecure Default The Admin Console has an insecure default warning if the default users are not removed.

Once DDF is configured to use an external user (such as LDAP), remove the users.properties file from the <DDF_HOME>/etc directory. Use of a users.properties file should be limited to emergency recovery operations and replaced as soon as effectively possible.

The deletion of the default users in the users.properties file can be done automatically after 72 hours. This feature can be found at Admin Console → Admin → Default Users Deletion Scheduler → Enable default users automatic deletion.

Warning

Once the default users are removed, the <DDF_HOME>/bin/client and <DDF_HOME>/bin/client.bat scripts will not work. If SSH access to the Karaf shell is to be supported, edit the file org.apache.karaf.shell.cfg in the <INSTALL_HOME>/etc directory, changing the value of the sshRealm property from karaf to ldap.

Note

Emergency Use of users.properties file

Typically, the DDF does not manage passwords. Authenticators are stored in an external identity management solution. However, administrators may temporarily use a users.properties file for emergencies.

If a system recovery account is configured in users.properties, ensure:

The use of this account should be for as short a time as possible.
The default username/password of “admin/admin” should not be used.
All organizational standards for password complexity should still apply.
The password should be encrypted. For steps on how, see the section "Passwords Encryption" at https://karaf.apache.org/manual/latest/security.

Note	Compliance Reviews It is recommended to perform yearly reviews of accounts for compliance with organizational account management requirements.

7.4.8. Disallowing Login Without Certificates

DDF can be configured to prevent login without a valid PKI certificate.

Navigate to the Admin Console.
Select Security.
Select Web Context Policy Manager.
Add a policy for each context requiring restriction.
- For example: /search=PKI will disallow login without certificates to the Search UI.
- The format for the policy should be: /<CONTEXT>=PKI
Click Save.

Note	Ensure certificates comply with organizational hardening policies.

7.4.9. Managing Certificate Revocation

Required Step for Security Hardening

For hardening purposes, it is recommended to implement a way to verify a Certificate Revocation List (CRL) at least daily or an Online Certificate Status Protocol (OCSP) server.

7.4.9.1. Managing a Certificate Revocation List (CRL)

A Certificate Revocation List is a collection of formerly-valid certificates that should explicitly not be accepted.

7.4.9.1.1. Creating a CRL

Create a CRL in which the token issuer’s certificate is valid. The example uses OpenSSL.

$> openssl ca -gencrl -out crl-tokenissuer-valid.pem

Note	Windows and OpenSSL Windows does not include OpenSSL by default. For Windows platforms, a additional download of OpenSSL or an alternative is required.

Revoke a Certificate and Create a New CRL that Contains the Revoked Certificate

$> openssl ca -revoke tokenissuer.crt

$> openssl ca -gencrl -out crl-tokenissuer-revoked.pem

Viewing a CRL

Use the following command to view the serial numbers of the revoked certificates: $> openssl crl -inform PEM -text -noout -in crl-tokenissuer-revoked.pem

7.4.9.1.2. Enabling Certificate Revocation

Note	Enabling CRL revocation or modifying the CRL file will require a restart of DDF to apply updates.

Place the CRL in <DDF_HOME>/etc/keystores.
Add the line org.apache.ws.security.crypto.merlin.x509crl.file=etc/keystores/<CRL_FILENAME> to the following files (Replace <CRL_FILENAME> with the URL or file path of the CRL location):
1. <DDF_HOME>/etc/ws-security/server/encryption.properties
2. <DDF_HOME>/etc/ws-security/issuer/encryption.properties
3. <DDF_HOME>/etc/ws-security/server/signature.properties
4. <DDF_HOME>/etc/ws-security/issuer/signature.properties
(Replace <CRL_FILENAME> with the file path or URL of the CRL file used in previous step.)

Adding this property will also enable CRL revocation for any context policy implementing PKI authentication. For example, adding an authentication policy in the Web Context Policy Manager of /search=PKI will disable basic authentication and require a certificate for the search UI. If a certificate is not in the CRL, it will be allowed through, otherwise it will get a 401 error. If no certificate is provided, and guest access is enabled on the web context policy, guest access will be granted.

This also enables CRL revocation for the STS endpoint. The STS CRL Interceptor monitors the same encryption.properties file and operates in an identical manner to the PKI Authenication’s CRL handler. Enabling the CRL via the encryption.properties file will also enable it for the STS, and also requires a restart.

If the CRL cannot be placed in <DDF_HOME>/etc/keystores but can be accessed via an HTTPS URL:

Navigate to the Admin Console.
Select the Security application.
Select the Configuration tab.
Select Certificate Revocation List (CRL)
Add the HTTPS URL under CRL URL address
Check the Enable CRL via URL option

A local CRL file will be created and the encryption.properties and signature.properties files will be set as mentioned above.

Add Revocation to a Web Context

The PKIHandler implements CRL revocation, so any web context that is configured to use PKI authentication will also use CRL revocation if revocation is enabled.

After enabling revocation (see above), open the Web Context Policy Manager.
Add or modify a Web Context to use PKI in authentication. For example, enabling CRL for the search ui endpoint would require adding an authorization policy of /search=PKI
If guest access is also required, check the 'Allow Guest Access` box in the policy.

With guest access, a user with a revoked certificate will be given a 401 error, but users without a certificate will be able to access the web context as the guest user.

The STS CRL interceptor does not need a web context specified. The CRL interceptor for the STS will become active after specifying the CRL file path, or the URL for the CRL, in the encryption.properties file and restarting DDF.

Note	Disabling or enabling CRL revocation or modifying the CRL file will require a restart of DDF to apply updates. If CRL checking is already enabled, adding a new context via the Web Context Policy Manager will not require a restart.

Adding Revocation to an Endpoint

Note	This section explains how to add CXF’s CRL revocation method to an endpoint and not the CRL revocation method in the `PKIHandler`.

This guide assumes that the endpoint being created uses CXF and is being started via Blueprint from inside the OSGi container. If other tools are being used the configuration may differ.

Add the following property to the jasws endpoint in the endpoint’s blueprint.xml:

<entry key="ws-security.enableRevocation" value="true"/>

Example xml snippet for the jaxws:endpoint with the property:

<jaxws:endpoint id="Test" implementor="#testImpl"
                wsdlLocation="classpath:META-INF/wsdl/TestService.wsdl"
                address="/TestService">

    <jaxws:properties>
        <entry key="ws-security.enableRevocation" value="true"/>
    </jaxws:properties>
</jaxws:endpoint>

Verifying Revocation

A Warning similar to the following will be displayed in the logs of the source and endpoint showing the exception encountered during certificate validation:

11:48:00,016 | WARN  | tp2085517656-302 | WSS4JInInterceptor               | ecurity.wss4j.WSS4JInInterceptor  330 | 164 - org.apache.cxf.cxf-rt-ws-security - 2.7.3 |

7.4.9.2. Managing an Online Certificate Status Protocol (OCSP) Server

An Online Certificate Status Protocol is a protocol used to verify the revocation status of a certificate. An OCSP server can be queried with a certificate to verify if it is revoked.

The advantage of using an OCSP Server over a CRL is the fact that a local copy of the revoked certificates is not needed.

7.4.9.2.1. Enabling OCSP Revocation

Navigate to the Admin Console.
Select the Security application.
Select the Configuration tab.
Select Online Certificate Status Protocol (OCSP)
Add the URL of the OCSP server under OCSP server URL.
Check the Enable validating a certificate against an OCSP server option.

Note	If an error occurs while communicating with the OCSP server, an alert will be posted to the Admin Console. Until the error is resolved, certificates will not be verified against the server.

7.5. Configuring Data Management

Data ingested into DDF has security attributes that can be mapped to users' permissions to ensure proper access. This section covers configurations that ensure only the appropriate data is contained in or exposed by DDF.

7.5.1. Configuring Solr

The default catalog provider for DDF is Solr. If using another catalog provider, see Changing Catalog Providers.

7.5.1.1. Configuring Solr Catalog Provider Synonyms

When configured, text searches in Solr will utilize synonyms when attempting to match text within the catalog. Synonyms are used during keyword/anyText searches as well as when searching on specific text attributes when using the like / contains operator. Text searches using the equality / exact match operator will not utilize synonyms.

Solr utilizes a synonyms.txt file which exists for each Solr core. Synonym matching is most pertinent to metacards which are contained within 2 cores: catalog and metacard_cache.

7.5.1.1.1. Defining synonym rules in the Solr Provider

Edit the synonyms.txt file under the catalog core. For each synonym group you want to define, add a line with the synonyms separated by a comma. For example:

United States, United States of America, the States, US, U.S., USA, U.S.A

Save the file
Repeat the above steps for the metacard_cache core.
Restart the DDF.

Note	Data does not have to be re-indexed for the synonyms to take effect.

7.5.1.2. Hardening Solr

The following sections provide hardening guidance for Solr; however, they are provided only as reference and additional security requirements may be added.

7.5.1.2.1. Hardening Solr Server Configuration

The Solr server configuration is configured to be secure by default. No additional hardening should be necessary. The default configuration starts Solr with TLS enabled and basic authentication required. That means DDF must trust Solr’s PKI certificate.

7.5.1.2.2. Solr Server Password Management

By default, DDF is configured to use Solr server. To verify this, view the property solr.client. If the property is set to HttpSolrClient, DDF is configured to use Solr server.

To ensure the security of its communication with Solr server, DDF sends HTTP requests over TLS. Solr is configured to use basic authentication to further ensure the requests originated from DDF. There are several system properties that control basic authentication and password management.

solr.useBasicAuthSend basic authentication header if property is true
solr.usernameUsername for basic authentication with Solr server.
solr.passwordPassword for basic authentication.
solr.attemptAutoPasswordChange If this property is true, DDF attempts to change the default password to a randomly generated secure password if it detects the default password is in use. The new password is encrypted and then stored in the system properties.

The Solr distrubition included with DDF comes already configured with a user. To see the username or default password, either inspect the file <DDF_HOME>/etc/custom.system.properties or refer to the properties here.

A limitation of the current implementation is that the Solr password is not recoverable. Further, the migration command does not currently migrate the password. It may be necessary to reset the password:

After a migration.
If the administator needs access to the Solr admin UI.
If the administator wants to use their own password.

Do not Autogenerate a Solr Password

To prevent DDF from attempting to change the password set the property solr.attemptAutoPasswordChange to false in the file <DDF_HOME>/etc/custom.system.properties

Change the Password to a Specific String

Note	If DDF has generated an encrypted password, the password must be reset before proceeding. Follow the procedure in Restore the Default Password in Solr before proceeding.

To change the Solr password to a specific string, send Solr an HTTP POST request. This is covered in the official Solr documentation . Here is an example that uses the command line utility curl to change the password from admin to newpassword:
```
curl -k -u "admin:admin" "https://{FQDN}:{PORT}/solr/admin/authentication" -H 'Content-type:application/json' -d "{ 'set-user': {'admin' : 'newpassword'}}"
```
Encrypt the password using the Encryption Service. The encryption command enciphers the password. It is safe to save the peristed password in a file.
Update property solr.password in the file <DDF_HOME>/etc/custom.system.properties` to be the ouput from the encryption command. Be sure to include ENC( and ) characters produced by the encryption comand. Note that the default password is not enclosed in ENC() because that is not necessary for cleartext. Cleartext is used by the system exactly as it appears. follow these instructions.
Finally, restart DDF

Restore the Default Password in Solr

Restore the <DDF_HOME>/solr/server/solr/security.json from a zip file of the DDF distribution.

Edit the <DDF_HOME>/solr/server/solr/security.json file. Solr stores a salted hash of the user passwords in this file.
Assuming the Solr username is admin, change the credentials section to match this string:
```
 "credentials": {
      "admin": "EjjOS/zyQ1KQQdSXFb/rFm7w6MItU5pmdthM35ZiJaA= ZZI7d4jf/8hz5oZz7ljBE6+uv1wqncj+VudX3arbib4="}
```
The quoted string following the username admin is the salted hash for the password admin.
Edit the file <DDF_HOME>/etc/custom.system.properties and change the value of solr.password to admin.
Optional: Prevent DDF from automatically changing the Solr password.

Removing Basic Authentication from Solr

To disable Solr’s basic authentication mechanism, rename or remove the file <DDF_HOME>/solr/server/solr/security.json and restart Solr. The file security.json configures Solr to use basic authetnication and defines Solr users. If the file is not present, Solr requires no login. This could a security issue in many environments and it is recommended to never disable Solr authentication in an operational environment. If authentication is disabled, the system property solr.useBasicAuth may be set to false.

7.5.1.2.3. Configuring Solr Encryption

While it is possible to encrypt the Solr index, it decreases performance significantly. An encrypted Solr index also can only perform exact match queries, not relative or contextual queries. As this drastically reduces the usefulness of the index, this configuration is not recommended. The recommended approach is to encrypt the entire drive through the Operating System of the server on which the index is located.

7.5.1.3. Accessing the Solr Admin UI

The Solr Admin UI for Solr server configurations can be accessed from a web browser with a username and password.

7.5.1.3.1. Solr Admin UI’s URL

The Solr server’s URL is configured in DDF’s custom.system.properties file. See solr.http.url for more information. An example of a typical URL for the Solr Admin UI is https://hostname:8994.

7.5.1.3.2. Solr Admin UI’s Username and Password

The Solr admin username is configured in the custom.system.properties file. See solr.username. The password is also stored in the custom.system.properties file, but the password is encrypted and not recoverable. See Solr Server Password Management.

7.5.2. Changing Catalog Providers

This scenario describes how to reconfigure DDF to use a different catalog provider.

This scenario assumes DDF is already running.

Uninstall Catalog Provider (if installed).

Navigate to the Admin Console.
Select the System tab.
Select the Features tab.
Find and Stop the installed Catalog Provider

Install the new Catalog Provider

Navigate to the Admin Console.
Select the System tab.
Select the Features tab.
Find and Start the desired Catalog Provider.

7.5.3. Changing Hostname

By default, the STS server, STS client and the rest of the services use the system property org.codice.ddf.system.hostname which is defaulted to 'localhost' and not to the fully qualified domain name of the DDF instance. Assuming the DDF instance is providing these services, the configuration must be updated to use the fully qualified domain name as the service provider. If the DDF is being accessed from behind a proxy or load balancer, set the system property org.codice.ddf.external.hostname to the hostname users will be using to access the DDF.

This can be changed during Initial Configuration or later by editing the <DDF_HOME>/etc/custom.system.properties file.

7.5.4. Configuring Errors and Warnings

DDF performs several types of validation on metadata ingested into the catalog. Depending on need, configure DDF to act on the warnings or errors discovered.

7.5.4.1. Enforcing Errors or Warnings

Prevent data with errors or warnings from being ingested at all.

Navigate to the Admin Console.
Select the Catalog application.
Select Configuration.
Select Metacard Validation Marker Plugin.
Enter ID of validator(s) to enforce.
Select Enforce errors to prevent ingest for errors.
Select Enforce warnings to prevent ingest for warnings.

7.5.4.2. Hiding Errors or Warnings from Queries

Prevent invalid metacards from being displayed in query results, unless specifically queried.

Navigate to the Admin Console.
Select the Catalog application.
Select Configuration.
Select Catalog Federation Strategy.
Deselect Show Validations Errors to hide metacards with errors.
Deselect Show Validations Warnings to hide metacards with warnings.

7.5.4.3. Hiding Errors and Warnings from Users Based on Role

Required Step for Security Hardening

Prevent certain users from seeing data with certain types of errors or warnings. Typically, this is used for security markings. If the Metacard Validation Filter Plugin is configured to Filter errors and/or Filter warnings, metacards with errors/warnings will be hidden from users without the specified user attributes.

Navigate to the Admin Console.
Select the Catalog application.
Select Configuration.
Select Metacard Validation Filter Plugin.

For Attribute map, enter both the metacard SECURITY attribute to filter and the user attribute to filter.

The default attribute for viewing invalid metacards is invalid-state

invalid-state=<USER ROLE>.

Replace <USER ROLE> with the roles that should be allowed to view invalid metacards.

Note	To harden the system and prevent other DDF systems from querying invalid data in the local catalog, it is recommended to create and set user roles that are unique to the local system (ie. a user role that includes a UUID).

Select Filter errors to filter errors. Users without the invalid-state attribute will not see metacards with errors.
Select Filter warnings to filter warnings. Users without the invalid-state attribute will not see metacards with warnings.

7.5.5. Content Directory Monitor

The Content Directory Monitor (CDM) provides the capability to easily add content and metacards into the Catalog by placing a file in a directory.

7.5.5.1. Installing the Content Directory Monitor

The Content Directory Monitor is installed by default with a standard installation of the Catalog application.

7.5.5.2. Configuring Permissions for the Content Directory Monitor

Tip	If monitoring a WebDav server, then adding these permissions is not required and this section can be skipped.

Configuring a Content Directory Monitor requires adding permissions to the Security Manager before CDM configuration.

Configuring a CDM requires adding read and write permissions to the directory being monitored. The following permissions, replacing <DIRECTORY_PATH> with the path of the directory being monitored, are required for each configured CDM and should be placed in the CDM section inside <DDF_HOME>/security/configurations.policy.

Warning

Adding New Permissions

After adding permissions, a system restart is required for them to take effect.

permission java.io.FilePermission "<DIRECTORY_PATH>", "read";
permission java.io.FilePermission "<DIRECTORY_PATH>${/}-", "read, write";

Trailing slashes after <DIRECTORY_PATH> have no effect on the permissions granted. For example, adding a permission for "${/}test${/}path" and "${/}test${/}path${/}" are equivalent. The recursive forms "${/}test${/}path${/}-", and "${/}test${/}path${/}${/}-" are also equivalent.

Line 1 gives the CDM the permissions to read from the monitored directory path. Line 2 gives the CDM the permissions to recursively read and write from the monitored directory path, specified by the directory path’s suffix "${/}-".

If a CDM configuration is deleted, then the corresponding permissions that were added should be deleted to avoid granting unnecessary permissions to parts of the system.

7.5.5.3. Configuring the Content Directory Monitor

Important

Content Directory Monitor Permissions

When configuring a Content Directory Monitor, make sure to set permissions on the new directory to allow DDF to access it. Setting permissions should be done before configuring a CDM. Also, don’t forget to add permissions for products outside of the monitored directory. See Configuring Permissions for the Content Directory Monitor for in-depth instructions on configuring permissions.

Note	If there’s a metacard that points to a resource outside of the CDM, then you must configure the URL Resource Reader to be able to download it.

Warning

Monitoring Directories In Place

If monitoring a directory in place, then the URL Resource Reader must be configured prior to configuring the CDM to allow reading from the configured directory. This allows the Catalog to download the products.

Configure the CDM from the Admin Console:

Navigate to the Admin Console.
Select the Catalog application.
Select the Configuration tab.
Select Catalog Content Directory Monitor.

See Content Directory Monitor configurations for all possible configurations.

7.5.5.4. Using the Content Directory Monitor

The CDM processes files in a directory, and all of its sub-directories. The CDM offers three options:

Delete
Move
Monitor in place

Regardless of the option, the DDF takes each file in a monitored directory structure and creates a metacard for it. The metacard is linked to the file. The behavior of each option is given below.

Delete

Copies the file into the Content Repository.
Creates a metacard in the Catalog from the file.
Erases the original file from the monitored directory.

Move

Copies the file into the directory .\ingested (this will double the disk space used)
Copies the file into the Content Repository.
Creates a metacard in the Catalog from the file.
Erases the original file from the monitored directory.

Monitor in place

Creates a metacard in the Catalog from the file.
Creates a reference from the metacard to the original file in the monitored directory.
If the original file is deleted, the metacard is removed from the Catalog.
If the original file is modified, the metacard is updated to reflect the new content.
If the original file is renamed, the old metacard is deleted and a new metacard is created.

Parallel Processing

The CDM supports parallel processing of files (up to 8 files processed concurrently). This is configured by setting the number of Maximum Concurrent Files in the configuration. A maximum of 8 is imposed to protect system resources.

Read Lock

When the CDM is set up, the directory specified is continuously scanned, and files are locked for processing based on the ReadLock Time Interval. This does not apply to the Monitor in place processing directive. Files will not be ingested without having a ReadLock that has observed no change in the file size. This is done so that files that are in transit will not be ingested prematurely. The interval should be dependent on the speed of the copy to the directory monitor (ex. network drive vs local disk). For local files, the default value of 500 milliseconds is recommended. The recommended interval for network drives is 1000 - 2000 milliseconds. If the value provided is less than 100, 100 milliseconds will be used. It is also recommended that the ReadLock Time Interval be set to a lower amount of time when the Maximum Concurrent Files is set above 1 so that files are locked in a timely manner and processed as soon as possible. When a higher ReadLock Time Interval is set, the time it takes for files to be processed is increased.

Attribute Overrides

The CDM supports setting metacard attributes directly when DDF ingests a file. Custom overrides are entered in the form:

attribute-name=attribute-value

For example, to set the contact email for all metacards, add the attribute override:

contact.point-of-contact-email=doctor@clinic.com

Each override sets the value of a single metacard attribute. To set the value of an additional attribute, select the "plus" icon in the UI. This creates an empty line for the entry.

To set multi-valued attributes, use a separate override for each value. For example, to add the keywords PPI and radiology to each metacard, add the custom attribute overrides:

topic.keyword=PPI
topic.keyword=radiology

Attributes will only be overridden if they are part of the metacard type or are injected.

All attributes in the catalog taxonomy tables are injected into all metacards by default and can be overridden.

Important

If an overridden attribute is not part of the metacard type or injected the attribute will not be added to the metacard.

For example, if the metacard type contains contact email,

contact.point-of-contact-email

but the value is not currently set, adding an attribute override will set the attribute value. To override attributes that are not part of the metacard type, attribute injection can be used.

Blacklist

The CDM blacklist uses the "bad.files" and "bad.file.extensions" properties from the custom.system.properties file in "etc/" in order to prevent malicious or unwanted data from being ingested into DDF. While the CDM automatically omits hidden files, this is particularly useful when an operating system automatically generates files that should not be ingested. One such example of this is "thumbs.db" in Windows. This file type and any temporary files are included in the blacklist.

Errors

If the CDM fails to read the file, an error will be logged in the ingest log. If the directory monitor is configured to Delete or Move, the original file is also moved to the \.errors directory.

Other

Multiple directories can be monitored. Each directory has an independent configuration.
To support the monitoring in place behavior, DDF indexes the files to track their names and modification timestamps. This enables the Content Directory Monitor to take appropriate action when files are changed or deleted.
The Content Directory Monitor recursively processes all subdirectories.

7.5.6. Configuring System Usage Message

The Platform UI configuration contains the settings for displaying messages to users at login or in banners in the headers and footers of all pages. For, example this configuration can provide warnings that system usage is monitored or controlled.

Configuring System Usage Message

Navigate to the Admin Console.
Select the Platform application.
Select Configuration.
Select Platform UI Configuration.
Select Enable System Usage Message.
Enter text in the remaining fields and save.

See the Platform UI for all possible configurations.

7.5.7. Configuring Data Policy Plugins

Configure the data-related policy plugins to determine the accessibility of data held by DDF.

7.5.7.1. Configuring the Metacard Attribute Security Policy Plugin

The Metacard Attribute Security Policy Plugin combines existing metacard attributes to make new attributes and adds them to the metacard.

Navigate to the Admin Console.
Select the Catalog application tile
Select the Configuration tab
Select the Metacard Attribute Security Policy Plugin.

Sample configuration of the Metacard Attribute Security Policy Plugin.

To configure the plugin to combine the attributes sourceattribute1 and sourceattribute2 into a new attribute destinationattribute1 using the union, enter these two lines under the title Metacard Union Attributes

Metacard Union Attributes

sourceattribute1=destinationattribute1

sourceattribute2=destinationattribute1

See Metacard Attribute Security Policy Plugin configurations for all possible configurations.

7.5.7.2. Configuring the Metacard Validation Marker Plugin

By default, the Metacard Validation Marker Plugin will mark metacards with validation errors and warnings as they are reported by each metacard validator and then allow the ingest. To prevent the ingest of certain invalid metacards, the Metacard Validity Marker plugin can be configured to "enforce" one or more validators. Metacards that are invalid according to an "enforced" validator will not be ingested.

Navigate to the Admin Console.
Select the Catalog application.
Select the Configuration tab.
Select the Metacard Validity Marker Plugin.
1. If desired, enter the ID of any metacard validator to enforce. This will prevent ingest of metacards that fail validation.
2. If desired, check Enforce Errors or Enforce Warnings, or both.

See Metacard Validity Marker Plugin configurations for all possible configurations.

7.5.7.3. Configuring the Metacard Validity Filter Plugin

The Metacard Validity Filter Plugin determines whether metacards with validation errors or warnings are filtered from query results.

Navigate to the Admin Console.
Select the Catalog application.
Select the Configuration tab.
Select the Metacard Validity Filter Plugin.
1. Check Filter Errors to hide metacards with errors from users.
2. Check Filter Warnings to hide metacards with warnings from users.

See Metacard Validity Filter Plugin configurations for all possible configurations.

7.5.7.4. Configuring the XML Attribute Security Policy Plugin

The XML Attribute Security Policy Plugin finds security attributes contained in a metacard’s metadata.

Navigate to the Admin Console.
Select the Catalog application tile.
Select the Configuration tab.
Select the XML Attribute Security Policy Plugin configuration.

See XML Attribute Security Policy Plugin configurations for all possible configurations.

7.5.8. Configuring Data Access Plugins

Configure access plugins to act upon the rules and attributes configured by the policy plugins and user attributes.

7.5.8.1. Configuring the Security Audit Plugin

The Security Audit Plugin audits specific metacard attributes.

To configure the Security Audit Plugin:

Navigate to the Admin Console.
Select Catalog application.
Select Configuration tab.
Select Security Audit Plugin.

Add the desired metacard attributes that will be audited when modified.

See Security Audit Plugin configurations for all possible configurations.

7.6. Configuring Security Policies

User attributes and Data attributes are matched by security policies defined within DDF.

7.6.1. Configuring the Web Context Policy Manager

The Web Context Policy Manager defines all security policies for REST endpoints within DDF. It defines:

the realms a context should authenticate against.
the type of authentication that a context requires.
any user attributes required for authorization.

See Web Context Policy Manager Configurations for detailed descriptions of all fields.

7.6.1.1. Guest Access

Guest access is a toggleable configuration. Enabling guest access will cause all users to be assigned a guest principal for use throughout the entire system. The guest principal will be used either by itself or along with any other principals acquired from configured authentication types.

7.6.1.2. Session Storage

Enabling session storage allows the system to persist the user login through the use of cookies. Note that the SAML and OIDC authentication types require session storage to be enabled.

7.6.1.3. Authentication Types

As you add REST endpoints, you may need to add different types of authentication through the Web Context Policy Manager.

Any web context that allows or requires specific authentication types should be added here with the following format:

/<CONTEXT>=<AUTH_TYPE>|<AUTH_TYPE|...

Table 17. Default Types of Authentication
Authentication Type	Description
`BASIC`	Activates basic authentication.
`PKI`	Activates public key infrastructure authentication.
`SAML`	Activates single-sign on (SSO) across all REST endpoints that use SAML.
`OIDC`	Activates single-sign on (SSO) across all REST endpoints that use OIDC.

7.6.1.3.1. Terminating and Non-Terminating Authentication Types

Terminating authentication types are authentication types where, once hit, must either allow or forbid access to the system. No other authentication types will be checked once a terminating authentication type is hit.

Non-Terminating authentication types are authentication types where, once hit, must first verify that the client supports the authentication type’s method of obtaining credentials. If the client supports the non-terminating authentication type’s method of obtaining credentials, it either allows or forbids access to the system. However if the client does not support the non-terminating authentication type’s method of obtaining credentials, the system will continue to the next configured authentication type.

BASIC is the only terminating authentication type. Every other authentication type is non-terminating.

For example: assume a context is protected by the non-terminating SAML authorization type. The system first checks to see if the client supports the acquisition of SAML credentials.

If the connecting client is a browser, the system can acquire SAML credentials.
If the connecting client is a machine that supports SAML ECP, the system can acquire SAML credentials.
If the connecting client is a machine that does not support SAML ECP, the system cannot acquire SAML credentials.

If the system can acquire SAML credentials from the client, the system will attempt to acquire said credentials and either allow or forbid access. If the system cannot acquire SAML credentials from the client, the system will continue to the next configured authentication type.

Contrarily, assume a context is protected by the terminating BASIC authentication type. Once this authentication type is hit, the system either allows or forbids access to the system, without checking if the client supports the acquisition of BASIC credentials.

7.6.1.4. Required Attributes

The fields for required attributes allows configuring certain contexts to only be accessible to users with pre-defined attributes. For example, the default required attribute for the /admin context is role=system-admin, limiting access to the Admin Console to system administrators

7.6.1.5. White Listed Contexts

White listed contexts are trusted contexts which will bypass security. Any sub-contexts of a white listed context will be white listed as well, unless they are specifically assigned a policy.

7.6.2. Configuring Catalog Filtering Policies

Filtering is the process of evaluating security markings on data products, comparing them to the users permissions and protecting resources from inappropriate access.

There are two options for processing filtering policies: internally, or through the use of a policy formatted in eXtensible Access Control Markup Language (XACML). The procedure for setting up a policy differs depending on whether that policy is to be used internally or by the external XACML processing engine.

7.6.2.1. Setting Internal Policies

Navigate to the Admin Console.
Select the Security application.
Click the Configuration tab.
Click on the Security AuthZ Realm configuration.
Add any attribute mappings necessary to map between subject attributes and the attributes to be asserted.
1. For example, the above example would require two Match All mappings of subjectAttribute1=assertedAttribute1 and subjectAttribute2=assertedAttribute2`
2. Match One mappings would contain subjectAttribute3=assertedAttribute3 and subjectAttribute4=assertedAttribute4.

With the security-pdp-authz feature configured in this way, the above Metacard would be displayed to the user. Note that this particular configuration would not require any XACML rules to be present. All of the attributes can be matched internally and there is no reason to call out to the external XACML processing engine. For more complex decisions, it might be necessary to write a XACML policy to handle certain attributes.

7.6.2.2. Setting XACML Policies

To set up a XACML policy, place the desired XACML policy in the <distribution root>/etc/pdp/policies directory and update the included access-policy.xml to include the new policy. This is the directory in which the PDP will look for XACML policies every 60 seconds.

See Developing XACML Policies for more information about custom XACML policies.

7.6.2.3. Catalog Filter Policy Plugins

Several Policy Plugins for catalog filtering exist currently: Metacard Attribute Security Policy Plugin and XML Attribute Security Policy Plugin. These Policy Plugin implementations allow an administrator to easily add filtering capabilities to some standard Metacard types for all Catalog operations. These plugins will place policy information on the Metacard itself that allows the Filter Plugin to restrict unauthorized users from viewing content they are not allowed to view.

7.8. Configuring Federation

DDF is able to federate to other data sources, including other instances of DDF, with some simple configuration.

7.8.1. Enable SSL for Clients

In order for outbound secure connections (HTTPS) to be made from components like Federated Sources and Resource Readers configuration may need to be updated with keystores and security properties. These values are configured in the <DDF_HOME>/etc/custom.system.properties file. The following values can be set:

Property Sample Value Description

javax.net.ssl.trustStore

etc/keystores/serverTruststore.jks

The java keystore that contains the trusted public certificates for Certificate Authorities (CA’s) that can be used to validate SSL Connections for outbound TLS/SSL connections (e.g. HTTPS). When making outbound secure connections a handshake will be done with the remote secure server and the CA that is in the signing chain for the remote server’s certificate must be present in the trust store for the secure connection to be successful.

javax.net.ssl.trustStorePassword

changeit

This is the password for the truststore listed in the above property

javax.net.ssl.keyStore

etc/keystores/serverKeystore.jks

The keystore that contains the private key for the local server that can be used for signing, encryption, and SSL/TLS.

javax.net.ssl.keyStorePassword

changeit

The password for the keystore listed above

javax.net.ssl.keyStoreType

jks

The type of keystore

https.cipherSuites

TLS_DHE_RSA_WITH_AES_128_GCM_SHA256, TLS_DHE_RSA_WITH_AES_128_CBC_SHA256, TLS_DHE_RSA_WITH_AES_128_CBC_SHA, TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256, TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256

The cipher suites that are supported when making outbound HTTPS connections

https.protocols

TLSv1.1,TLSv1.2

The protocols that are supported when making outbound HTTPS connections

jdk.tls.client.protocols

TLSv1.1,TLSv1.2

The protocols that are supported when making inbound HTTPS connections

jdk.tls.ephemeralDHKeySize

'matched'

For X.509 certificate based authentication (of non-exportable cipher suites), the DH key size matching the corresponding authentication key is used, except that the size must be between 1024 bits and 2048 bits. For example, if the public key size of an authentication certificate is 2048 bits, then the ephemeral DH key size should be 2048 bits unless the cipher suite is exportable. This key sizing scheme keeps the cryptographic strength consistent between authentication keys and key-exchange keys.

Note	`<DDF_HOME>` Directory DDF is installed in the `<DDF_HOME>` directory.

7.8.2. Configuring HTTP(S) Ports

To change HTTP or HTTPS ports from the default values, edit the custom.system.properties file.

Open the file at <DDF_HOME>/etc/custom.system.properties
Change the value after the = to the desired port number(s):
1. org.codice.ddf.system.httpsPort=8993 to org.codice.ddf.system.httpsPort=<PORT>
2. org.codice.ddf.system.httpPort=8181 to org.codice.ddf.system.httpPort=<PORT>
Restart DDF for changes to take effect.

Important

Do not use the Admin Console to change the HTTP port. While the Admin Console’s Pax Web Runtime offers this configuration option, it has proven to be unreliable and may crash the system.

7.8.3. Configuring HTTP Proxy

The platform-http-proxy feature proxies https to http for clients that cannot use HTTPS and should not have HTTP enabled for the entire container via the etc/org.ops4j.pax.web.cfg file.

Enabling the HTTP Proxy from the Admin Console

Navigate to the Admin Console.
Select the System tab.
Select the Features tab.
Select platform-http-proxy.
Select the Play button to the right of the word “Uninstalled”

Enabling the HTTP Proxy from the Command Console

Type the command feature:install platform-http-proxy

Configuring HTTP Proxy Hostname

Select Configuration tab.
Select HTTP to HTTPS Proxy Settings
1. Enter the Hostname to use for HTTPS connection in the proxy.
Click Save changes.

Note	HTTP Proxy and Hostname The hostname should be set by default. Only configure the proxy if this is not working.

7.8.4. Federation Strategy

A federation strategy federates a query to all of the Remote Sources in the query’s list, processes the results in a unique way, and then returns the results to the client. For example, implementations can choose to halt processing until all results return and then perform a mass sort or return the results back to the client as soon as they are received back from a Federated Source.

An endpoint can optionally specify the federation strategy to use when it invokes the query operation. Otherwise, the Catalog provides a default federation strategy that will be used: the Catalog Federation Strategy.

7.8.4.1. Configuring Federation Strategy

The Catalog Federation Strategy configuration can be found in the Admin Console.

Navigate to Admin Console.
Select Catalog
Select Configuration
Select Catalog Federation Strategy.

See Federation Strategy configurations for all possible configurations.

7.8.4.1.1. Catalog Federation Strategy

The Catalog Federation Strategy is the default federation strategy and is based on sorting metacards by the sorting parameter specified in the federated query.

The possible sorting values are:

metacard’s effective date/time
temporal data in the query result
distance data in the query result
relevance of the query result

The supported sorting orders are ascending and descending.

The default sorting value/order automatically used is relevance descending.

Warning

The Catalog Federation Strategy expects the results returned from the Source to be sorted based on whatever sorting criteria were specified. If a metadata record in the query results contains null values for the sorting criteria elements, the Catalog Federation Strategy expects that result to come at the end of the result list.

7.8.5. Connecting to Sources

A source is a system consisting of a catalog containing Metacards.

Catalog sources are used to connect Catalog components to data sources, local and remote. Sources act as proxies to the actual external data sources, e.g., a RDBMS database or a NoSQL database.

Types of Sources

Remote Source: Read-only data sources that support query operations but cannot be used to create, update, or delete metacards.
Federated Sources: A federated source is a remote source that can be included in federated queries by request or as part of an enterprise query. Federated sources support query and site information operations only. Catalog modification operations, such as create, update, and delete, are not allowed. Federated sources also expose an event service, which allows the Catalog Framework to subscribe to event notifications when metacards are created, updated, and deleted.

Catalog instances can also be federated to each other. Therefore, a Catalog can also act as a federated source to another Catalog.
Connected Sources: A Connected Source is a local or remote source that is always included in every local and enterprise query, but is hidden from being queried individually. A connected source’s identifier is removed in all query results by replacing it with DDF’s source identifier. The Catalog Framework does not reveal a connected source as a separate source when returning source information responses.
Catalog Providers: A Catalog Provider is used to interact with data providers, such as files systems or databases, to query, create, update, or delete data. The provider also translates between DDF objects and native data formats.

All sources, including federated source and connected source, support queries, but a Catalog provider also allows metacards to be created, updated, and deleted. A Catalog provider typically connects to an external application or a storage system (e.g., a database), acting as a proxy for all catalog operations.
Catalog Stores: A Catalog Store is an editable store that is either local or remote.

Configuring the Confluence Federated Source

Configure an Existing Confluence Federated Source through the Admin Console:

Navigate to the Admin Console.
Select the Catalog application.
Select the Sources tab.
Select the name of the source to edit.

See Confluence Federated Source configurations for all possible configurations.

Important

If an additional attribute is not part of the Confluence metacard type or injected, the attribute will not be added to the metacard.

Usage Limitations of the Confluence Federated Source

Most of the fields that can be queried on Confluence have some sort of restriction on them. Most of the fields do not support the like aka ~ operation so the source will convert like queries to equal queries for attributes that don’t support like. If the source receives a query with attributes it doesn’t understand, it will just ignore them. If the query doesn’t contain any attributes that map to Confluence search attributes, an empty result set will be returned.

Depending on your version of Confluence, when downloading attachments you might get redirected to a different download URL. The default URLResourceReader configuration allows redirects, but if the option was disabled in the past, the download will fail. This can be fixed by re-enabling redirects in the URLResourceReader configuration.

7.8.5.7. Registry Store

The Registry Store is the interface that allows CSW messages to be turned into usable Registry metacards and for those metacards to be turned back into CSW messages.

Installing Registry Store

The Registry Store is installed by default with the Registry application.

Configuring Registry Store

To configure the Registry store:

Navigate to the Admin Console.
Select Registry.
Select the Remote Registries Tab and click the Add button.
1. ALTERNATIVELY: Select the Configuration Tab and select Registry Store.

7.8.5.8. Solr Catalog Provider

The Solr Catalog Provider is included with a standard installation of DDF. There are two configurations available:

Solr Server (default)::

DDF is bundled with a distribution of Apache Solr. This distribution includes special JAR libraries used by DDF. This DDF scripts manage the starting and stopping of the Solr server. Considerations include:

No configuration necessary. Simply start DDF and DDF manages starting and stopping the Solr server.
Backup can be performed using DDF console’s backup command.
This configuration cannot be scaled larger than the single Solr server.
All data is located inside the {$branding} home directory. If the Solr index grows large, the storage volume may run low on space.

Installing Solr Server

No installation is required because DDF includes a distribution of Apache Solr.

Configuring Solr Server

No configuration.

Solr Cloud

Solr Cloud is a cluster of distributed Solr servers used for high availability and scalability. If the DDF needs to be available with little or no downtime, then the Solr Cloud configuration should be used. The general considerations for selecting this configuration are:

SolrCloud can scale to support over 2 billion indexed documents.
Has network overhead and requires additional protection to be secure.
Installation is more involved (requires Zookeeper)
Configuration and administration is more complex due to replication, sharding, etc.
No way to backup currently, but will automatically recover from system failure.

Configuration shared between Solr Server instances is managed by Zookeeper. Zookeeper helps manage the overall structure.

Solr Cloud Deployment

Note	The instructions on setting up Solr Cloud for DDF only include setup in a *NIX environment.

Solr Cloud Prerequisites

Before Solr Cloud can be installed:

ZooKeeper 3.4.5 (Refer to https://zookeeper.apache.org/doc/r3.1.2/zookeeperStarted.html#sc_Download for installation instructions.)
*NIX environment
JDK 8 or greater

Note

A minimum of three Zookeeper nodes required. Three Zookeeper nodes are needed to form a quorum. A three Zookeeper ensemble allows for a single server to fail and the service will still be available. More Zookeeper nodes can be added to achieve greater fault tolerance. The total number of nodes must always be an odd number. See Setting Up an External Zoo Keeper Ensemble for more information.

Installing Solr Cloud

Before starting the install procedure, download the extension jars. The jars are needed to support geospatial and xpath queries and need to be installed on every Solr server instance after the Solr Cloud installation instructions have been followed.

The JARs can be found here:

Repeat the following procedure for each Solr server instance that will be part of the Solr Cloud cluster:

Refer to https://cwiki.apache.org/confluence/display/solr/Apache+Solr+Reference+Guide for installation instructions.
Copy jts-core-1.15.0.jar to: <SOLR_INSTALL_DIR>/server/solr-webapp/webapp/WEB-INF/lib/.
Copy solr-xpath-2.21.6.jar to: <SOLR_INSTALL_DIR>/plugins/.

Note

A minimum of two Solr server instances is required. Each Solr server instance must have a minimum of two shards. Having two Solr server instances guarantees that at least one Solr server is available if one fails. The two shards enables the document mapping to be restored if one shard becomes unavailable.

Configuring Solr Cloud

On the DDF server, edit <DDF_HOME>/etc/custom.system.properties:
1. Comment out the Solr Client Configuration for Http Solr Client section.
2. Uncomment the section for the Cloud Solr Client:
3. Set solr.cloud.zookeeper to <ZOOKEEPER_1_HOSTNAME>:<PORT_NUMBER>, <ZOOKEEPER_2_HOSTNAME>:<PORT_NUMBER>, <ZOOKEEPER_n_HOSTNAME>:<PORT_NUMBER>
4. Set solr.data.dir to the desired data directory.

Solr Cloud System Properties

solr.client = CloudSolrClient
solr.data.dir = ${karaf.home}/data/solr
solr.cloud.zookeeper = zk1:2181,zk2:2181,zk3:2181

7.8.5.9. WFS 1.0 Source

The WFS Source allows for requests for geographical features across the web using platform-independent calls.

A Web Feature Service (WFS) source is an implementation of the FederatedSource interface provided by the DDF Framework.

Use the WFS Source if querying a WFS version 1.0.0 compliant service.

Installing the WFS v1.0.0 Source

The WFS v1.0.0 Source is installed by default with a standard installation in the Spatial application.

Configure a new WFS v1.0.0 Source through the Admin Console:

Navigate to the Admin Console.
Select the Catalog application.
Select the Sources tab.
Add a New source.
Name the New source.
Select WFS v1.0.0 Source from Binding Configurations.

Configuring the WFS v1.0.0 Source

Configure an existing WFS v1.0.0 Source through the Admin Console:

Navigate to the Admin Console.
Select the Catalog application.
Select the Sources tab.
Select the name of the source to edit.

See WFS v.1.0 Federated Source configurations or WFS v1.0 Connected Source configurations for all possible configurations.a

WFS URL

The WFS URL must match the endpoint for the service being used. The type of service and version are added automatically, so they do not need to be included. Some servers will throw an exception if they are included twice, so do not include those.

The syntax depends on the server. However, in most cases, the syntax will be everything before the ? character in the URL that corresponds to the GetCapabilities query.

Example GeoServer 2.5 Syntax

http://www.example.org:8080/geoserver/ows?service=wfs&version=1.0.0&request=GetCapabilities

In this case, the WFS URL would be: http://www.example.org:8080/geoserver/ows

7.8.5.10. WFS 1.1 Source

The WFS Source allows for requests for geographical features across the web using platform-independent calls.

A Web Feature Service (WFS) source is an implementation of the FederatedSource interface provided by the DDF Framework.

Use the WFS Source if querying a WFS version 1.1.0 compliant service.

Installing the WFS v1.1.0 Source

The WFS v1.1.0 Source is installed by default with a standard installation in the Spatial application.

Configure a new WFS v1.1.0 Source through the Admin Console:

Navigate to the Admin Console.

Navigate to the Admin Console.
Select the Catalog application.
Select the Sources tab.
Select the name of the source to edit.

See WFS v.1.1 Federated Source configurations for all possible configurations.

WFS URL

The syntax depends on the server. However, in most cases, the syntax will be everything before the ? character in the URL that corresponds to the GetCapabilities query.

Example GeoServer 2.12.1 Syntax

http://www.example.org:8080/geoserver/wfs?service=wfs&version=1.1.0&request=GetCapabilities

In this case, the WFS URL would be: http://www.example.org:8080/geoserver/wfs

Mapping Metacard Attributes to WFS Feature Properties for Queries

The WFS v1.1.0 Source supports mapping metacard attributes to WFS feature properties for queries (GetFeature requests) to the WFS server. The source uses a MetacardMapper service to determine how to map a given metacard attribute in a query to a feature property the WFS server understands. It looks for a MetacardMapper whose getFeatureType() matches the feature type being queried. Any MetacardMapper service implementation will work, but DDF provides one in the Spatial application called Metacard to WFS Feature Map.

7.8.5.11. WFS 2.0 Source

The WFS 2.0 Source allows for requests for geographical features across the web using platform-independent calls.

Use the WFS Source if querying a WFS version 2.0.0 compliant service. Also see Working with WFS Sources.

Installing the WFS v2.0.0 Source

The WFS v2.0.0 Source is installed by default with a standard installation in the Spatial application.

Configure a new WFS v2.0.0 Source through the Admin Console:

Navigate to the Admin Console.
Select the Catalog application.
Select the Sources tab.
Add a new source.
Name the new source.
Select WFS v2.0.0 Source from Binding Configurations.

Configuring the WFS v2.0.0 Source

Navigate to the Admin Console.
Select the Catalog application.
Select the Sources tab.
Select the name of the source to edit.

See WFS v.2.0 Federated source configurations or WFS v2.0 Connected source configurations for all possible configurations.

WFS URL

The WFS URL must match the endpoint for the service being used. The type of service and version is added automatically, so they do not need to be included. Some servers will throw an exception if they are included twice, so do not include those.

The syntax depends on the server. However, in most cases, the syntax will be everything before the ? character in the URL that corresponds to the GetCapabilities query.

Example GeoServer 2.5 Syntax

http://www.example.org:8080/geoserver/ows?service=wfs&version=2.0.0&request=GetCapabilities

In this case, the WFS URL would be

http://www.example.org:8080/geoserver/ows

Mapping WFS Feature Properties to Metacard Attributes

The WFS 2.0 Source allows for virtually any schema to be used to describe a feature. A feature is roughly equivalent to a metacard. The MetacardMapper was added to allow an administrator to configure which feature properties map to which metacard attributes.

Using the WFS MetacardMapper

Use the WFS MetacardMapper to configure which feature properties map to which metacard attributes when querying a WFS version 2.0.0 compliant service. When feature collection responses are returned from WFS sources, a default mapping occurs which places the feature properties into metacard attributes, which are then presented to the user via DDF. There can be situations where this automatic mapping is not optimal for your solution. Custom mappings of feature property responses to metacard attributes can be achieved through the MetacardMapper. The MetacardMapper is set by creating a feature file configuration which specifies the appropriate mapping. The mappings are specific to a given feature type.

Installing the WFS MetacardMapper

The WFS MetacardMapper is installed by default with a standard installation in the Spatial application.

Configuring the WFS MetacardMapper

There are two ways to configure the MetacardMapper:

The Configuration Admin available in the Admin Console.
Placing a feature.xml file in the deploy directory.

Example WFS MetacardMapper Configuration

The following shows how to configure the MetacardMapper to be used with the sample data provided with GeoServer. This configuration shows a custom mapping for the feature type ‘states’. For the given type, we are taking the feature property ‘STATE_NAME’ and mapping it to the metacard attribute ‘title’. In this particular case, since we mapped the state name to title in the metacard, it will now be fully searchable.

Example MetacardMapper Configuration Within a feature.xml file:


  1
2
3
4
5
6
7

  <feature name="geoserver-states" version="2.21.6"
    description="WFS Feature to Metacard mappings for GeoServer Example {http://www.openplans.org/topp}states">
    <config name="org.codice.ddf.spatial.ogc.wfs.catalog.mapper.MetacardMapper-geoserver.http://www.openplans.org/topp.states">
        featureType = {http://www.openplans.org/topp}states
        titleMapping = STATE_NAME
    </config>
</feature>

7.8.6. Configuring Endpoints

To install the CSW endpoint:

Navigate to the Admin Console.
Select System.
Select Features.
Install the csw-endpoint feature.

To control the number of threads used for parallel processing of transactions, set the org.codice.ddf.spatial.ogc.csw.catalog.endpoint.threadpool system property in custom.system.properties. The default thread pool is 2 * Number Processors.

7.8.6.3. Configuring FTP Endpoint

The FTP endpoint provides a method for ingesting files directly into the DDF Catalog using the FTP protocol The files sent over FTP are not first written to the file system, as the Directory Monitor does, but instead the FTP stream of the file is ingested directly into the DDF catalog, thus avoiding extra I/O overhead.

To install the FTP endpoint:

Navigate to the Admin Console.
Select System.
Select Features.
Install the catalog-ftp feature.

To configure the FTP endpoint:

Navigate to the Admin Console.
Select System.
Select Features.

See FTP Endpoint configurations for all possible configurations.

7.8.6.4. Configuring KML Endpoint

Keyhole Markup Language (KML) is an XML notation for describing geographic annotation and visualization for 2- and 3- dimensional maps.

The root network link will create a network link for each configured source, including the local catalog. The individual source network links will perform a query against the OpenSearch Endpoint periodically based on the current view in the KML client. The query parameters for this query are obtained by a bounding box generated by Google Earth. The root network link will refresh every 12 hours or can be forced to refresh. As a user changes their current view, the query will be re-executed with the bounding box of the new view. (This query gets re-executed two seconds after the user stops moving the view.)

This KML Network Link endpoint has the ability to serve up custom KML style documents and Icons to be used within that document. The KML style document must be a valid XML document containing a KML style. The KML Icons should be placed in a single level directory and must be an image type (png, jpg, tif, etc.). The Description will be displayed as a pop-up from the root network link on Google Earth. This may contain the general purpose of the network and URLs to external resources.

To install the KML endpoint:

Navigate to the Admin Console.
Select System.
Select Features.
Install the spatial-kml feature.

To configure the KML endpoint:

Navigate to the Admin Console.
Select System.
Select Features.
Select KML Endpoint.

See KML Endpoint configurations for all possible configurations.

7.8.6.5. Configuring OpenSearch Endpoint

The OpenSearch endpoint enables a client to send query parameters and receive search results. This endpoint uses the input query parameters to create an OpenSearch query. The client does not need to specify all of the query parameters, only the query parameters of interest.

To install the KML endpoint:

Navigate to the Admin Console.
Select System.
Select Features.
Install the catalog-opensearch-endpoint feature.

The OpenSearch endpoint has no configurable properties. It can only be installed or uninstalled.

7.8.6.6. Configuring WPS Endpoint

The WPS endpoint enables a client to execute and monitor long running processes.

To install the WPS endpoint:

Navigate to the Admin Console.
Select System.
Select Features.
Install the spatial-wps feature.

The WPS endpoint has no configurable properties. It can only be installed or uninstalled.

7.8.6.7. Compression Services

DDF supports compression of outgoing and incoming messages through the Compression Services. These compression services are based on CXF message encoding.

The formats supported in DDF are:

gzip: Adds GZip compression to messages through CXF components. Code comes with CXF.
exi: Adds Efficient XML Interchange (EXI) support to outgoing responses. EXI is an W3C standard for XML encoding that shrinks xml to a smaller size than normal GZip compression.

To Install a compression service:

Navigate to the Admin Console.
Select the System tab.
Select the Features tab.
Start the service for the desired compression format:
- compression-exi
- compression-gzip

Warning

The compression services either need to be installed BEFORE the desired CXF service is started or the CXF service needs to be refreshed / restarted after the compression service is installed.

Compression services have no configurable properties. They can only be installed or uninstalled.

7.8.7. Federating Through a Registry

Another approach to configuring federation is to use the Registry application to locate sources in a network/enterprise. See Registry Application Reference for details on installing the Registry application. Use the registry to subscribe to and federate with other instances of DDF.

Note	The Node Information and Remote Registries tabs appear in both the Registry application and the Catalog application.

7.9. Environment Hardening

Required Step for Security Hardening

Important

It is recommended to apply the following security mitigations to the DDF.

7.9.1. Known Issues with Environment Hardening

The session timeout should be configured longer than the UI polling time or you may get session timeout errors in the UI.

Protocol/Type

Risk

Mitigation

JMX

tampering, information disclosure, and unauthorized access

Stop the management feature using the command line console: feature:stop management.

File System Access

tampering, information disclosure, and denial of service

Set OS File permissions under the <DDF_HOME> directory (e.g. /deploy, /etc) to ensure unauthorized viewing and writing is not allowed.

If Caching is installed:

Set permissions for the installation directory /data/product-cache such that only the DDF process and users with the appropriate permissions can view any stored product.
Caching can be turned off as well to mitigate this risk.
- To disable caching, navigate to Admin Console.
- Select the Catalog application.
- Select Resource Download Settings.
- Uncheck the Enable Product Caching box.
Install Security to ensure only the appropriate users are accessing the products.
- Navigate to the Admin Console
- Select Manage.
- Install the Security application, if applicable.
Cached files are written by the user running the DDF process/application.

On system: ensure that not everyone can change ACLs on your object.

SSH

tampering, information disclosure, and denial of service

By default, SSH access to DDF is only enabled to connections originating from the same host running DDF. For remote access to DDF, first establish an SSH session with the host running DDF. From within that session, initiate a new SSH connection (to localhost), and use the sshPort as configured in the file <DDF_HOME>/etc/org.apache.karaf.shell.cfg.

To allow direct remote access to the DDF shell from any host, change the value of the sshHost property to 0.0.0.0 in the <DDF_HOME>/etc/org.apache.karaf.shell.cfg file.

SSH can also be authenticated and authorized through an external Realm, such as LDAP. This can be accomplished by editing the <DDF_HOME>/etc/org.apache.karaf.shell.cfg file and setting the value for sshRealm, e.g. to ldap. No restart of DDF is necessary after this change.

By definition, all connections over SSH will be authenticated and authorized and secure from eavesdropping.

Warning

Enabling SSH will expose your file system such that any user with access to your DDF shell will have read/write/execute access to all directories and files accessible to your installation user.

Because of this, SSH is not recommended in a secure environment and should be turned off in a fully hardened system.

Set karaf.shutdown.port=-1 in <DDF_HOME>/etc/custom.properties or <DDF_HOME>/etc/config.properties.

SSL/TLS

man-in-the-middle, information disclosure

Update the <DDF_HOME>/etc/org.ops4j.pax.web.cfg file to add the entry org.ops4j.pax.web.ssl.clientauthneeded=true.

Warning

Setting this configuration may break compatibility to legacy systems that do not support two-way SSL.

Warning

Setting this configuration will require a certificate to be installed in the browser.

Session Inactivity Timeout

unauthorized access

Update the Session configuration to have no greater than a 10 minute Session Timeout.

Navigate to the Admin Console.
Select the Security application.
Select the Configuration tab.
Select Session.
Set Session Timeout (in minutes) to 10 (or less).

Shell Command Access

command injection

By default, some shell commands are disabled in order to secure the system. DDF includes a whitelist of allowed shell commands in <DDF_HOME>/etc/org.apache.karaf.command.acl.shell.cfg.

By default, this list includes commands that are whitelisted only to administrators:

complete
echo
format
grep
if
keymap
less
set
setopt
sleep
tac
wc
while
.invoke
unsetopt

7.10. Configuring for Special Deployments

In addition to standard configurations, several specialized configurations are possible for specific uses of DDF.

7.10.1. Multiple Installations

One common specialized configuration is installing multiple instances of DDF.

7.10.1.1. Reusing Configurations

The Migration Export/Import capability allows administrators to export the current DDF configuration and use it to restore the same state for either a brand new installation or a second node for a Highly Available Cluster.

Important

There are some key limitations when following this process to reuse configurations for a different versions of DDF. See Reusing Configurations Across Different Versions below.

To export the current configuration settings:

Run the command migration:export from the Command Console.
Files named ddf-2.21.6.dar, ddf-2.21.6.dar.key, and ddf-2.21.6.dar.sha256 will be created in the exported directory underneath <DDF_HOME>. The .dar file contains the encrypted information. The .key and .sha256 files contains the encryption key and a validation checksum. Copy the '.dar' file to a secure location and copy the '.key' and '.sha256' to a different secure location. Keeping all 3 files together represents a security risk and should be avoided.

To import previously exported configuration settings:

Unzip the DDF distribution.
Restore all external files, softlinks, and directories that would not have been exported and for which warnings would have been generated during export. This could include (but is not limited to) external certificates or monitored directories.
Start up the newly unzipped DDF distribution.
Make sure to install and re-enable the DDF service on the new system if it was installed and enabled on the original system.
Copy the previously exported files from your secure locations to the exported directory underneath <DDF_HOME>.
Either:
1. If an administrator wishes to restore the original profile along with the configuration (experimental, see 'NOTE' below this list):
  1. Run the command migration:import with the option --profile from the Command Console (see 'NOTE' below this list)
2. Otherwise:
  1. Step through the installation process one of 2 ways:
    
    If network profile needs to be configured, install through the UI Admin Console.
    
    Else, install by running the command profile:install standard in the Command Console.
  2. Run the command migration:import from the Command Console.
DDF will automatically restart if the command is successful. Otherwise address any generated warnings before manually restarting DDF.

Note

The --profile command enables the installed profile from the original system to be restored. It cannot be used if upgrading from an older version.

'Experimental' in this context denotes the continuing development of using migration:import along with --profile to restore the original profile with the configuration.

It is possible to decrypt the previously exported configuration settings but doing so is insecure and appropriate measures should be taken to secure the resulting decrypted file. To decrypt the exported file:

Copy all 3 exported files (i.e. .dar, .key, and .sha256) to the exported directory underneath <DDF_HOME>.
Run the command migration:decrypt from the Command Console.
A file named ddf-2.21.6.zip will be created in the exported directory underneath <DDF_HOME>. This file represents the decrypted version of the .dar file.

Important

The following is currently not supported when importing configuration files:
- importing from a system installed on a different OS
- importing from a system installed in a different directory location
To keep the export/import process simple and consistent, all system configuration files are required to be under the <DDF_HOME> directory and not be softlinks. Presence of external files or symbolic links during export will not fail the export; they will yield warnings. It will be up to the administrator to manually copy these files over to the new system before proceeding with the import. The import process will verify their presence and consistency and yield warnings if they don’t match the original files.
The import process will restore all configurations done on the original system as part of the hardening process including changes to starting scripts and certificates.
The import process can also restore the profile from the original system by restoring all applications, features, and/or bundles to the same state (i.e., installed, uninstalled, started, stopped, …) they were in originally. Doing so is currently experimental and was tested only with the standard and HA profiles.

7.10.1.1.1. Reusing Configurations Across Different Versions

The same step-by-step process above can be followed when migrating configurations between DDF instances of different versions, with a few key constraints:

Only a subset of configuration files are currently imported:
- Files under etc/ws-security
- Files under etc/pdp
- etc/users.attributes and etc/users.properties
- security/configurations.policy
- etc/system.properties
- etc/custom.system.properties (the solr.password property will be preserved)
- Keystores
- Truststores
- Service wrapper *.conf files, if the DDF is installed as a service
- Select Admin Console configurations, including:
  - Content Directory Monitor
  - URL Resource Reader
  - Web Context Policy Manager
  - Guest Claims Configuration
  - Security STS Server
  - Session
  - Catalog Federation Strategy
  - Catalog Standard Framework
  - Metacard Validation Filter Plugin
  - Metacard Validation Marker Plugin
  - All Catalog Source configurations
  - All Registry configurations
    
    Warning
    If a supported configuration is being imported across versions, any corresponding .config files in the etc directory will not be put into the etc directory of the importing system.
There is a list of specific DDF versions that have been tested that can be found in etc/migration.properties under the property supported.versions, as a comma-delimited list. The system will only allow importing configurations from those versions.

7.10.1.2. Isolating Solr Cloud and Zookeeper

Required Step for Security Hardening (if using Solr Cloud/Zookeeper)

Zookeeper cannot use secure (SSL/TLS) connection. The configuration information that Zookeeper sends and receives is vulnerable to network sniffing. Also, the connections between the local Solr Catalog service and the Solr Cloud is not necessarily secure. The connections between Solr Cloud nodes are not necessarily secure. Any unencrypted network traffic is vulnerable to sniffing attacks. To use Solr Cloud and Zookeeper securely, these processes must be isolated on the network, or their communications must be encrypted by other means. The DDF process must be visible on the network to allow authorized parties to interact with it.

Examples of Isolation:

Create a private network for Solr Cloud and Zookeeper. Only DDF is allowed to contact devices inside the private network.
Use IPsec to encrypt the connections between DDF, Solr Cloud nodes, and Zookeeper nodes.
Put DDF, Solr Cloud and Zookeeper behind a firewall that only allows access to DDF.

7.10.2. Configuring for a Fanout Proxy

Optionally, configure DDF as a fanout proxy such that only queries and resource retrieval requests are processed and create/update/delete requests are rejected. All queries are enterprise queries and no catalog provider needs to be configured.

Navigate to the Admin Console.
Select the Catalog application.
Select the Configuration tab.
Select Catalog Standard Framework.
Select Enable Fanout Proxy.
Save changes.

DDF is now operating as a fanout proxy. Only queries and resource retrieval requests will be allowed. All queries will be federated. Create, update, and delete requests will not be allowed, even if a Catalog Provider was configured prior to the reconfiguration as a fanout.

7.10.3. Standalone Security Token Service (STS) Installation

To run a STS-only DDF installation, uninstall the catalog components that are not being used. The following list displays the features that can be uninstalled to minimize the runtime size of DDF in an STS-only mode. This list is not a comprehensive list of every feature that can be uninstalled; it is a list of the larger components that can be uninstalled without impacting the STS functionality.

Unnecessary Features for Standalone STS

catalog-core-standardframework
catalog-opensearch-endpoint
catalog-opensearch-souce
catalog-rest-endpoint

7.10.4. Configuring for a Highly Available Cluster

This section describes how to make configuration changes after the initial setup for a DDF in a Highly Available Cluster.

In a Highly Available Cluster, configuration changes must be made on both DDF nodes. The changes can still be made in the standard ways via the Admin Console, the Command Line, or the file system.

Note

Changes made in the Admin Console must be made through the HTTP proxy. This means that the below steps should be followed to make a change in the Admin Console:

Make a configuration change on the currently active DDF node
Shut down the active DDF node, making the failover proxy switch to the standby DDF node
Make the same configuration change on the newly active DDF node
Start the DDF node that was just shut down

7.11. Configuring UI Themes

The optional configurations in this section cover minor changes that can be made to optimize DDF appearance.

7.11.1. Landing Page

The Landing Page is the first page presented to users of DDF. It is customizable to allow adding organizationally-relevant content.

7.11.1.1. Installing the Landing Page

The Landing Page is installed by default with a standard installation.

7.11.1.2. Configuring the Landing Page

The DDF landing page offers a starting point and general information for a DDF node. It is accessible at /(index|home|landing(.htm|html)).

7.11.1.3. Customizing the Landing Page

Configure the Landing Page from the Admin Console:

Navigate to the Admin Console.
Select Platform Application.
Select Configuration tab.
Select Landing Page.

Configure important landing page items such as branding logo, contact information, description, and additional links.

See Landing Page configurations for all possible configurations.

7.11.2. Configuring Logout Page

The logout pages is presented to users through the navigation of DDF and has a changeable timeout value.

Navigate to the Admin Console.
Select Security Application.
Select Configuration tab.
Select Logout Page.

The customizable feature of the logout page is the Logout Page Time Out. This is the time limit the IDP client will wait for a user to click log out on the logout page. Any requests that take longer than this time for the user to submit will be rejected.

Default value: 3600000 (milliseconds)

See Logout Configuration for detailed information.

7.11.3. Platform UI Themes

The Platform UI Configuration allows for the customization of attributes of all pages within DDF. It contains settings to display messages to users at login or in banners in the headers and footers of all pages, along with changing the colors of text and backgrounds.

7.11.3.1. Navigating to UI Theme Configuration

Navigate to the Admin Console.
Select the Platform application.
Select Configuration.
Select Platform UI Configuration.

7.11.3.2. Customizing the UI Theme

The customization of the UI theme across DDF is available through the capabilities of Platform UI Configuration. The banner has four items to configure:

Header (text)
Footer (text)
Text Color
Background Color

See the Platform UI for all possible configurations of the Platform UI Configuration.

7.12. Miscellaneous Configurations

The optional configurations in this section cover minor changes that can be made to optimize DDF.

7.12.1. Configuring Thread Pools

The org.codice.ddf.system.threadPoolSize property can be used to specify the size of thread pools used by:

Federating requests between DDF systems
Downloading resources
Handling asynchronous queries, such as queries from the UI

By default, this value is set to 128. It is not recommended to set this value extremely high. If unsure, leave this setting at its default value of 128.

7.12.2. Configuring Jetty ThreadPool Settings

To prevent resource shortages in the event of concurrent requests, DDF allows configuring Jetty ThreadPool settings to specify the minimum and maximum available threads.

The settings can be changed at etc/org.ops4j.pax.web.cfg under Jetty Server ThreadPool Settings.
Specify the maximum thread amount with org.ops4j.pax.web.server.maxThreads
Specify the minimum thread amount with org.ops4j.pax.web.server.minThreads
Specify the allotted time for a thread to complete with org.ops4j.pax.web.server.idleTimeout

DDF does not support changing ThreadPool settings from the Command Console or the Admin Console.

7.12.3. Configuring Alerts

By default, DDF uses two services provided by Karaf Decanter for alerts that can be configured by configuration file. Further information on Karaf Decanter services and configurations can be found here .

7.12.3.1. Configuring Decanter Service Level Agreement (SLA) Checker

The Decanter SLA Checker provides a way to create alerts based on configurable conditions in events posted to decanter/collect/* and can be configured by editing the file <DDF_HOME>/etc/org.apache.karaf.decanter.sla.checker.cfg. By default there are only two checks that will produce alerts, and they are based on the SystemNotice event property of priority.

Table 24. Decanter SLA Configuration
Property	Alert Level	Expression	Description
priority	warn	equal:1,2,4	Produce a warn level alert if priority is important (3)
priority	error	equal:1,2,3	Produce an error level alert if priority is critical (4)

7.12.3.2. Configuring Decanter Scheduler

The Decanter Scheduler looks up services implementing the Runnable interface with the service-property decanter.collector.name and executes the Runnable periodically. The Scheduler can be configured by editing the file <DDF_HOME>/etc/org.apache.karaf.decanter.scheduler.simple.cfg.

Table 25. Decanter Scheduler Configuration
Property Name	Description	Default Value
period	Decanter simple scheduler period (milliseconds)	300000 (5 minutes)
threadIdleTimeout	The time to wait before stopping an idle thread (milliseconds)	60000 (1 minute)
threadInitCount	Initial number of threads created by the scheduler	5
threadMaxCount	Maximum number of threads created by the scheduler	200

7.12.4. Encrypting Passwords

DDF includes an encryption service to encrypt plain text such as passwords.

7.12.4.1. Encryption Command

An encrypt security command is provided with DDF to encrypt text. This is useful when displaying password fields to users.

Below is an example of the security:encrypt command used to encrypt the plain text myPasswordToEncrypt.

Navigate to the Command Console.
security:encrypt Command Example
```
ddf@local>security:encrypt myPasswordToEncrypt
```
The output is the encrypted value.
security:encrypt Command Output
```
ddf@local>bR9mJpDVo8bTRwqGwIFxHJ5yFJzatKwjXjIo/8USWm8=
```

8. Running

Find directions here for running an installation of DDF.

Starting: Getting an instance of DDF up and running.
Managing Services: Running DDF as a managed service.
Maintaining: Keeping DDF running with useful tasks.
Monitoring: Tracking system health and usage.
Troubleshooting: Common tips for unexpected behavior.

8.1. Starting

8.1.1. Run DDF as a Managed Service

8.1.1.1. Running as a Service with Automatic Start on System Boot

Because DDF is built on top of Apache Karaf, DDF can use the Karaf Wrapper to run DDF as a service and enable automatic startup and shutdown. When DDF is started using Karaf Wrapper, new wrapper.log and wrapper.log.n (where n goes from 1 to 5 by default) log files will be generated to include wrapper and console specific information.

Warning

When installing as a service on *NIX, do not use spaces in the path for <DDF_HOME> as the service scripts that are generated by the wrapper cannot handle spaces.

Warning

Ensure that JAVA_HOME is properly set before beginning this process. See Java Requirements

Create the service wrapper.

DDF can create native scripts and executable files to run itself as an operating system service. This is an optional feature that is not installed by default. To install the service wrapper feature, go the DDF console and enter the command:

ddf@local> feature:install -r wrapper

Generate the script, configuration, and executable files:

*NIX

ddf@local> wrapper:install -i setenv-wrapper.conf -n ddf -d ddf -D "DDF Service"

Windows

ddf@local> wrapper:install -i setenv-windows-wrapper.conf -n ddf -d ddf -D "DDF Service"

(Windows users skip this step) (All *NIX) If DDF was installed to run as a non-root user (as-recommended,) edit <DDF_HOME>/bin/ddf-service and change the property #RUN_AS_USER= to:
<DDF_HOME>/bin/ddf-service
```
RUN_AS_USER=<ddf-user>
```
where <ddf-user> is the intended username:
(Windows users skip down) (All *NIX) Edit <DDF_HOME>/bin/ddf-service. Add LimitNOFILE to the [Service] section.
<DDF_HOME>/bin/ddf.service
```
LimitNOFILE=6815744
```
(Windows users skip this step) (*NIX with systemd) Install the wrapper startup/shutdown scripts.

Install the service and start it when the system boots, use systemctl From an OS console, execute:

root@localhost# systemctl enable <DDF_HOME>/bin/ddf.service
(Windows users skip this step) (*NIX without systemd) Install the wrapper startup/shutdown scripts.

If the system does not use systemd, use the init.d system to install and configure the service. Execute these commands as root or superuser:
```
root@localhost# ln -s <DDF_HOME>/bin/ddf-service /etc/init.d/
root@localhost# chkconfig ddf-service --add
root@localhost# chkconfig ddf-service on
```

(Windows only, if the system’s JAVA_HOME variable has spaces in it) Edit <DDF_HOME>/etc/ddf-wrapper.conf. Put quotes around wrapper.java.additional.n system properties for n from 1 to 13 like so:

<DDF_HOME>/etc/ddf-wrapper.conf

wrapper.java.additional.1=-Djava.endorsed.dirs="%JAVA_HOME%/jre/lib/endorsed;%JAVA_HOME%/lib/endorsed;%KARAF_HOME%/lib/endorsed"
wrapper.java.additional.2=-Djava.ext.dirs="%JAVA_HOME%/jre/lib/ext;%JAVA_HOME%/lib/ext;%KARAF_HOME%/lib/ext"
wrapper.java.additional.3=-Dkaraf.instances="%KARAF_HOME%/instances"
wrapper.java.additional.4=-Dkaraf.home="%KARAF_HOME%"
wrapper.java.additional.5=-Dkaraf.base="%KARAF_BASE%"
wrapper.java.additional.6=-Dkaraf.data="%KARAF_DATA%"
wrapper.java.additional.7=-Dkaraf.etc="%KARAF_ETC%"
wrapper.java.additional.8=-Dkaraf.log="%KARAF_LOG%"
wrapper.java.additional.9=-Dkaraf.restart.jvm.supported=true
wrapper.java.additional.10=-Djava.io.tmpdir="%KARAF_DATA%/tmp"
wrapper.java.additional.11=-Djava.util.logging.config.file="%KARAF_ETC%/java.util.logging.properties"
wrapper.java.additional.12=-Dcom.sun.management.jmxremote
wrapper.java.additional.13=-Dkaraf.startLocalConsole=false
wrapper.java.additional.14=-Dkaraf.startRemoteShell=true

(Windows only) Install the wrapper startup/shutdown scripts.

Run the following command in a console window. The command must be run with elevated permissions.
```
<DDF_HOME>\bin\ddf-service.bat install
```
Startup and shutdown settings can then be managed through Services → MMC Start → Control Panel → Administrative Tools → Services.

8.1.1.2. Karaf Documentation

Because DDF is built on top of Apache Karaf, more information on operating DDF can be found in the Karaf documentation .

8.2. Managed Services

The lifecycle of DDF and Solr processes can be managed by the operating system. The DDF documentation provides instructions to install DDF as a managed services on supported unix platforms. However, the documentation cannot account for all possible configurations. Please consult the documentation for the operating system and its init manager if the instructions in this document are inadequate.

Configure Solr to run as a managed service
Configure DDF to run as a managed service

8.2.1. Run Solr as Managed Service

These instructions are for configuring Solr as a service managed by the operating system.

8.2.1.1. Configure Solr as a Windows Service

Windows users can use the Task Scheduler to start Solr as a background process.

If DDF is running, stop it.
Edit <DDF_HOME>/etc/custom.system.properties and set start.solr=false. This prevents the DDF scripts from attempting to manage Solr’s lifecycle.
Start the Windows Task Scheduler and open the Task Scheduler Library.
Under the Actions pane, select Create Basic Task….
Provide a useful name and description, then select Next.
Select When the computer starts as the Trigger and select Next.
Select Start a program as the Action and select Next.
Select the script to start Solr:
```
<DDF_HOME>\bin\ddfsolr.bat
```
Add the argument start in the window pane and select Next.
Review the settings and select Finish.

It may be necessary to update the Security Options under the task Properties to Run with highest privileges or setting user to "SYSTEM".

Additionally, the process can be set to restart if it fails. The option can be found in the the Properties > Settings tab.

Depending on the system it may also make sense to delay the process from starting for a few minutes until the machine has fully booted. Open the task’s Properties settings and

Select Triggers.
Select Edit.
Select Advanced Settings.
Select Delay Task.

8.2.1.2. Configure Solr as a Systemd Service

These instructions are for unix operating systems running the systemd init manager. If configuring a Windows system, see Configure Solr as a Windows Service

If DDF is running, stop it.
Edit <DDF_HOME>/etc/custom.system.properties and set start.solr=false.
Edit the file <DDF_HOME>/solr/services/solr.service
1. Edit the property Environment=JAVA_HOME and replace <JAVA_HOME> with the absolute path to the directory where the Java Runtime Environment is installed.
2. Edit the property ExecStart and replace <DDF_HOME> with the absolute path to the ddfsolr file.
3. Edit the property ExecStop and replace <DDF_HOME> with the absolute path to the ddfsolr file.
4. Edit the property User and replace <USER> with the user ID of the Solr process owner.
From the operating system command line, enable a Solr service using a provided configuration file. Use the full path to the file.
```
systemctl enable <DDF_HOME>/solr/service/solr.service
```
Start the service.
```
systemctl start solr
```
Check the status of Solr
```
systemctl status solr
```

Solr will start automatically each time the system is booted.

Follow the below steps to start and stop DDF.

8.2.2. Starting from Startup Scripts

Run one of the start scripts from a command shell to start the distribution and open a local console:

Start Script: *NIX

<DDF_HOME>/bin/ddf

Start Script: Windows

<DDF_HOME>/bin/ddf.bat

8.2.3. Starting as a Background Process

Alternatively, to run DDF as a background process, run the start script:

*NIX

<DDF_HOME>/bin/start

Windows

<DDF_HOME>/bin/start.bat

Note	If console access is needed while running as a service, run the `client` script on the host where the DDF is running: *NIX <DDF_HOME>/bin/client Windows <DDF_HOME>/bin/client.bat -h <FQDN> Use the `-h` option followed by the name (`<FQDN>`) or IP of the host where DDF is running.

8.2.4. Stopping DDF

There are two options to stop a running instance:

Call shutdown from the console:

Shut down with a prompt

ddf@local>shutdown

Force Shutdown without prompt

ddf@local>shutdown -f

Keyboard shortcut for shutdown
- Ctrl-D
- Cmd-D
Or run the stop script:

*NIX

<DDF_HOME>/bin/stop

Windows

<DDF_HOME>/bin/stop.bat

Important

Shut Down

Do not shut down by closing the window (Windows, Unix) or using the kill -9 <pid> command (Unix). This prevents a clean shutdown and can cause significant problems when DDF is restarted. Always use the shutdown command or the shortcut from the command line console.

8.3. Maintaining

8.3.1. Console Commands

Once the distribution has started, administrators will have access to a powerful command line console, the Command Console. This Command Console can be used to manage services, install new features, and manage the state of the system.

The Command Console is available to the user when the distribution is started manually or may also be accessed by using the bin/client.bat or bin/client scripts.

Note	The majority of functionality and information available on the Admin Console is also available on the Command Line Console.

8.3.1.1. Console Command Help

For details on any command, type help then the command. For example, help search (see results of this command in the example below).

Example Help

ddf@local>help search

                Interacts with the provider directly instead of the framework.

The help command provides a description of the provided command, along with the syntax in how to use it, arguments it accepts, and available options.

8.3.1.2. CQL Syntax

The CQL syntax used with console commands should follow the OGC CQL format. GeoServer provides a description of the grammar and examples in this CQL Tutorial .

CQL Syntax Examples

Finding all notifications that were sent due to a download:
ddf@local>store:list --cql "application='Downloads'" --type notification

Deleting a specific notification:
ddf@local>store:delete --cql "id='fdc150b157754138a997fe7143a98cfa'" --type notification

8.3.1.3. Available Console Commands

Many console commands are available, including DDF commands and the core Karaf console commands. For more information about these core Karaf commands and using the console, see the Commands documentation for Karaf 4.2.6 at Karaf documentation .

For a complete list of all available commands, from the Command Console, press TAB and confirm when prompted.

Console commands follow a format of namespace:command.

To get a list of commands, type in the namespace of the desired extension then press TAB.

For example, type catalog, then press TAB.

Table 26. DDF Console Command Namespaces
Namespace	Description
catalog	The Catalog Shell Commands are meant to be used with any `CatalogProvider` implementations. They provide general useful queries and functions against the Catalog API that can be used for debugging, printing, or scripting.
migrate	The Migrate Shell Commands provide functions to perform data migrations.
platform	The DDF Platform Shell Commands provide generic platform management functions
store	The Persistence Shell Commands are meant to be used with any `PersistentStore` implementations. They provide the ability to query and delete entries from the persistence store.
subscription	The DDF PubSub shell commands provide functions to list the registered subscriptions in DDF and to delete subscriptions.
solr	The Solr commands are used for the Solr `CatalogProvider` implementation. They provide commands specific to that provider.

The --created-after and --created-before options allow filtering on the date and time that the metacard was created, while --modified-after and --modified-before options allow filtering on the date and time that the metacard was last modified (which is the created date if no other modifications were made). These date ranges are exclusive (i.e., if the date and time match exactly, the metacard will not be included). The date filtering options (--created-after, --created-before, --modified-after, and --modified-before) can be used in any combination, with the export result including only metacards that match all of the provided conditions.

If no date filtering options are provided, created and modified dates are ignored, so that all metacards match.

Date Syntax

Supported dates are taken from the common subset of ISO8601, matching the datetime from the following syntax:

datetime          = time | date-opt-time
time              = 'T' time-element [offset]
date-opt-time     = date-element ['T' [time-element] [offset]]
date-element      = std-date-element | ord-date-element | week-date-element
std-date-element  = yyyy ['-' MM ['-' dd]]
ord-date-element  = yyyy ['-' DDD]
week-date-element = xxxx '-W' ww ['-' e]
time-element      = HH [minute-element] | [fraction]
minute-element    = ':' mm [second-element] | [fraction]
second-element    = ':' ss [fraction]
fraction          = ('.' | ',') digit+
offset            = 'Z' | (('+' | '-') HH [':' mm [':' ss [('.' | ',') SSS]]]

catalog:dump Examples

8.3.1.3.2. Solr Commands

Table 28. Solr Command Descriptions
Command	Description
`solr:backup`	Creates a backup of the selected Solr core/collection. This uses the Solr interface for creating the backup. In Solr Cloud deployments the selected backup directory must exist and be shared on all Solr nodes.
`solr:restore`	Restores a Solr backup to the selected core/collection. This uses the Solr interfaces for restoring the backup. In Solr Cloud deployments the directory containing the files to restore must exist and be shared on all Solr nodes.

8.3.1.3.3. Subscriptions Commands

Note	The subscriptions commands are installed when the Catalog application is installed.

Table 29. Subscription Command Descriptions
Command	Description
`subscriptions:delete`	Deletes the subscription(s) specified by the search phrase or LDAP filter.
`subscriptions:list`	List the subscription(s) specified by the search phrase or LDAP filter.

subscriptions:list Command Usage Examples

Note that no arguments are required for the subscriptions:list command. If no argument is provided, all subscriptions will be listed. A count of the subscriptions found matching the list command’s search phrase (or LDAP filter) is displayed first followed by each subscription’s ID.

List All Subscriptions

The example below illustrates searching for any subscription that has json and 172.18.14.169 in its subscription ID. This could be a handy way of finding all subscriptions for a specific site.

ddf@local>subscriptions:list -f "(&(subscription-id=*json*) (subscription-id=*172.18.14.169*))"

Total subscriptions found: 1

Subscription ID
my.contextual.id.json|http://172.18.14.169:8088/services/json/local/event/notification

subscriptions:delete Command Usage

The arguments for the subscriptions:delete command are the same as for the list command, except that a search phrase or LDAP filter must be specified. If one of these is not specified an error will be displayed. When the delete command is executed it will display each subscription ID it is deleting. If a subscription matches the search phrase but cannot be deleted, a message in red will be displayed with the ID. After all matching subscriptions are processed, a summary line is displayed indicating how many subscriptions were deleted out of how many matching subscriptions were found.

Delete a Specific Subscription Using Its Exact ID

ddf@local>subscriptions:delete "my.contextual.id.json|http://172.18.14.169:8088/services/json/local/event/notification"

8.3.1.3.4. Platform Commands

Table 30. Platform Command Descriptions
Command	Description
`platform:describe`	Shows the current platform configuration.
`platform:envlist`	Provides a list of environment variables.

8.3.1.3.5. Migrate Commands

Note

Migrate Command Descriptions

Performing a data migration creates, updates, or deletes existing metacards within the system. A data migration needs to be run when the structure of the data changes to ensure that existing resources function as expected. The effects of this command cannot be reverted or undone. It is highly recommended to back up the catalog before performing a data migration.

The syntax for the migration command is

migrate:data --list
migrate:data --all
migrate:data <serviceId>

Select the <serviceId> based on which data migration task you wish to run. To see a list of all data migrations tasks that are currently available, run the migrate:data --list command.

The --all option runs every data migration task that is available.

The --list option lists all available data migration tasks.

Note	If an error occurrs performing a data migration the specifics of that error are available in the logs or are printed to the karaf console.

8.3.1.3.6. Persistence Store Commands

Table 31. Persistence Store Command Descriptions
`Command`	Description
`store:delete`	Delete entries from the persistence store that match a given CQL statement
`store:list`	Lists entries that are stored in the persistence store.

8.3.1.4. Command Scheduler

The Command Scheduler allows administrators to schedule Command Line Commands to be run at specified intervals.

The Command Scheduler allows administrators to schedule Command Line Shell Commands to be run in a platform-independent way. For instance, if an administrator wanted to use the Catalog commands to export all records of a Catalog to a directory, the administrator could write a cron job or a scheduled task to remote into the container and execute the command. Writing these types of scripts are specific to the administrator’s operating system and also requires extra logic for error handling if the container is up. The administrator can also create a Command Schedule, which currently requires only two fields. The Command Scheduler only runs when the container is running, so there is no need to verify if the container is up. In addition, when the container is restarted, the commands are rescheduled and executed again. A command will be repeatedly executed indefinitely according to the configured interval until the container is shutdown or the Scheduled Command is deleted.

Note	There will be further attempts to execute the command according to the configured interval even if an attempt fails. See the log for details about failures.

8.3.1.4.1. Schedule a Command

Configure the Command Scheduler to execute a command at specific intervals.

Navigate to the Admin Console (https://{FQDN}:{PORT}/admin).
Select the Platform application.
Click on the Configuration tab.
Select Platform Command Scheduler.
Enter the command or commands to be executed in the Command text field. Commands can be separated by a semicolon and will execute in order from left to right.
Enter an interval in the Interval field. This can either be a Quartz Cron expression or a positive integer (seconds) (e.x. 0 0 0 1/1 * ? * or 12).
Select the interval type in the Interval Type drop-down.
Click the Save changes button.

Note	Scheduling commands will be delayed by 1 minute to allow time for bundles to load when DDF is starting up.

8.3.1.4.2. Updating a Scheduled Command

Change the timing, order, or execution of scheduled commands.

Navigate to the Admin Console.
Click on the Platform application.
Click on the Configuration tab.
Under the Platform Command Scheduler configuration are all of the scheduled commands. Scheduled commands have the following syntax: ddf.platform.scheduler.Command.{GUID} such as ddf.platform.scheduler.Command.4d60c917-003a-42e8-9367-1da0f822ca6e.
Find the desired configuration to modify, and update fields.
Click the Save changes button.

8.3.1.4.3. Output of Scheduled Commands

Commands that normally write out to the console will write out to the log. For example, if an echo "Hello World" command is set to run every five seconds, the log contains the following:

Sample Command Output in the Log

16:01:32,582 | INFO  | heduler_Worker-1 | ddf.platform.scheduler.CommandJob          68 | platform-scheduler   | Executing command [echo Hello World]
16:01:32,583 | INFO  | heduler_Worker-1 | ddf.platform.scheduler.CommandJob          70 | platform-scheduler   | Execution Output: Hello World
16:01:37,581 | INFO  | heduler_Worker-4 | ddf.platform.scheduler.CommandJob          68 | platform-scheduler   | Executing command [echo Hello World]
16:01:37,582 | INFO  | heduler_Worker-4 | ddf.platform.scheduler.CommandJob          70 | platform-scheduler   | Execution Output: Hello World

In short, administrators can view the status of a run within the log as long as INFO was set as the status level.

8.4. Monitoring

The DDF contains many tools to monitor system functionality, usage, and overall system health.

8.4.1. Metrics Reporting

Metrics are available in several formats and levels of detail.

Complete the following procedure now that several queries have been executed.

Select Platform
Select Metrics tab
For individual metrics, choose the format desired from the desired timeframe column:
1. PNG
2. CSV
3. XLS
For a detailed report of all metrics, at the bottom of the page are selectors to choose time frame and summary level. A report is generated in xls format.

8.4.2. Managing Logging

The DDF supports a dynamic and customizable logging system including log level, log format, log output destinations, roll over, etc.

8.4.2.1. Configuring Logging

Edit the configuration file <DDF_HOME>/etc/org.ops4j.pax.logging.cfg]

8.4.2.2. DDF log file

The name and location of the log file can be changed with the following setting:

log4j.appender.out.file=<DDF_HOME>/data/log/ddf.log

8.4.2.3. Controlling log level

A useful way to debug and detect issues is to change the log level:

log4j.rootLogger=DEBUG, out, osgi:VmLogAppender

8.4.2.4. Controlling the size of the log file

Set the maximum size of the log file before it is rolled over by editing the value of this setting:

log4j.appender.out.maxFileSize=20MB

8.4.2.5. Number of backup log files to keep

Adjust the number of backup files to keep by editing the value of this setting:

log4j.appender.out.maxBackupIndex=10

8.4.2.6. Enabling logging of inbound and outbound SOAP messages for the DDF SOAP endpoints

By default, the DDF start scripts include a system property enabling logging of inbound and outbound SOAP messages.

-Dcom.sun.xml.ws.transport.http.HttpAdapter.dump=true

In order to see the messages in the log, one must set the logging level for org.apache.cxf.services to INFO. By default, the logging level for org.apache.cxf is set to WARN.

ddf@local>log:set INFO org.apache.cxf.services

8.4.2.7. Logging External Resources

Other appenders can be selected and configured.

For more detail on configuring the log file and what is logged to the console see: Karaf Documentation: Log .

8.4.2.8. Enabling HTTP Access Logging

To enable access logs for the current DDF, do the following:

Update the jetty.xml file located in etc/ adding the following xml:

        <New class="org.eclipse.jetty.server.handler.RequestLogHandler">
          <Set name="requestLog">
            <New id="RequestLogImpl" class="org.eclipse.jetty.server.NCSARequestLog">
              <Arg><SystemProperty name="jetty.logs" default="data/log/"/>/yyyy_mm_dd.request.log</Arg>
              <Set name="retainDays">90</Set>
              <Set name="append">true</Set>
              <Set name="extended">false</Set>
              <Set name="LogTimeZone">GMT</Set>
            </New>
          </Set>
        </New>
      </Arg>
    </Call>
  </Get>

Change the location of the logs to the desired location. In the settings above, location will default to data/log (same place where the log is located).

The log is using National Center for Supercomputing Association Applications (NCSA) or Common format (hence the class 'NCSARequestLog'). This is the most popular format for access logs and can be parsed by many web server analytics tools. Here is a sample output:

127.0.0.1 -  -  [14/Jan/2013:16:21:24 +0000] "GET /favicon.ico HTTP/1.1" 200 0
127.0.0.1 -  -  [14/Jan/2013:16:21:33 +0000] "GET /services/ HTTP/1.1" 200 0
127.0.0.1 -  -  [14/Jan/2013:16:21:33 +0000] "GET /services//?stylesheet=1 HTTP/1.1" 200 0
127.0.0.1 -  -  [14/Jan/2013:16:21:33 +0000] "GET /favicon.ico HTTP/1.1" 200 0

8.4.2.9. Using the LogViewer

Navigate to the Admin Console
Navigate to the System tab
Select Logs

The LogViewer displays the most recent 500 log messages by default, but will grow to a maximum of 5000 messages. To view incoming logs, select the PAUSED button to toggle it to LIVE mode. Switching this back to PAUSED will prevent any new logs from being displayed in the LogViewer. Note that this only affects the logs displayed by the LogViewer and does not affect the underlying log.

Log events can be filtered by:

Log level (ERROR, WARNING, etc).
- The LogViewer will display at the currently configured log level for the Karaf logs.
  - See Controlling Log Level to change log level.
Log message text.
Bundle generating the message.

Warning

It is not recommended to use the LogViewer if the system logger is set to a low reporting level such as TRACE. The volume of messages logged will exceed the polling rate, and incoming logs may be missed.

The actual logs being polled by the LogViewer can still be accessed at <DDF_HOME>/data/log

Note	The LogViewer settings don’t change any of the underlying logging settings, only which messages are displayed. It does not affect the logs generated or events captured by the system logger.

8.5. Troubleshooting

If, after configuration, a DDF is not performing as expected, consult this table of common fixes and workarounds.

Table 32. General Troubleshooting
Issue	Solution
Unable to unzip distribution on Windows platform	The default Windows zip utility is not compatible with the DDF distribution zip file. Use Java or a third-party zip utility.
Unable to federate on Windows Platform	Windows default firewall is not compatible with DDF.
Ingesting more than 200,000 data files stored NFS shares may cause Java Heap Space error (Linux-only issue).	This is an NFS bug where it creates duplicate entries for some files when doing a file list. Depending on the OS, some Linux machines can handle the bug better and able get a list of files but get an incorrect number of files. Others would have a Java Heap Space error because there are too many file to list. As a workaround, ingest files in batches smaller than 200,000.
Ingesting serialized data file with scientific notation in WKT string causes RuntimeException.	WKT string with scientific notation such as POINT (-34.8932113039107 -4.77974239601E-5) won’t ingest. This occurs with serialized data format only.
Exception Starting DDF (Windows) An exception is sometimes thrown starting DDF on a Windows machine (x86). If using an unsupported terminal, `java.lang.NoClassDefFoundError: Could not initialize class org.fusesource.jansi.internal.Kernel32` is thrown.	Install missing Windows libraries. Some Windows platforms are missing libraries that are required by DDF. These libraries are provided by the Microsoft Visual C++ 2008 Redistributable Package x64 .
CXF BusException The following exception is thrown: `org.apache.cxf.BusException: No conduit initiator`	Restart DDF. . Shut down DDF: `ddf@local>shutdown` . Start up DDF: `./ddf`
Distribution Will Not Start DDF will not start when calling the start script defined during installation.	Complete the following procedure. Verify that Java is correctly installed. `java -version` This should return something similar to: `java version "1.8.0_45" Java™ SE Runtime Environment (build 1.8.0_45-b14) Java HotSpot™ Server VM (build 25.45-b02, mixed mode)` If running *nix, verify that bash is installed. `echo $SHELL` This should return: `/bin/bash`
Multiple `java.exe` processes running, indicating more than one DDF instance is running. This can be caused when another DDF is not properly shut down.	Perform one or all of the following recommended solutions, as necessary. Wait for proper shutdown of DDF prior to starting a new instance. Verify running java.exe are not DDF (e.g., kill/close if necessary). Utilize automated start/stop scripts to run DDF as a service.

8.5.1. Deleted Records Are Being Displayed In The Search UI’s Search Results

When queries are issued by the Search UI, the query results that are returned are also cached in an internal Solr database for faster retrieval when the same query may be issued in the future. As records are deleted from the catalog provider, this Solr cache is kept in sync by also deleting the same records from the cache if they exist.

Sometimes the cache may get out of sync with the catalog provider such that records that should have been deleted are not. When this occurs, users of the Search UI may see stale results since these records that should have been deleted are being returned from the cache. Records in the cache can be manually deleted using the URL commands listed below from a browser. In these command URLs, metacard_cache is the name of the Solr query cache.

To delete all of the records in the Solr cache:

Deletion of all records in Solr query cache

https://{FQDN}:{PORT}/solr/metacard_cache/update?stream.body=<delete><query>*:*</query></delete>&commit=true

To delete a specific record in the Solr cache by ID (specified by the original_id_txt field):

Deletion of record in Solr query cache by ID

https://{FQDN}:{PORT}/solr/metacard_cache/update?stream.body=<delete><query>original_id_txt:50ffd32b21254c8a90c15fccfb98f139</query></delete>&commit=true

To delete record(s) in the Solr cache using a query on a field in the record(s) - in this example, the title_txt field is being used with wildcards to search for any records with word remote in the title:

Deletion of records in Solr query cache using search criteria

https://{FQDN}:{PORT}/solr/metacard_cache/update?stream.body=<delete><query>title_txt:*remote*</query></delete>&commit=true

9. Data Management

9.1. Ingesting Data

Ingesting is the process of getting metacard(s) into the Catalog Framework. Ingested files are "transformed" into a neutral format that can be searched against as well as migrated to other formats and systems. There are multiple methods available for ingesting files into the DDF.

Note	Guest Claims Attributes and Ingest Ensure that appropriate Guest Claims are configured to allow guest users to ingest data and query the catalog.

9.1.1. Ingest Command

The Command Console has a command-line option for ingesting data.

Note	Ingesting with the console ingest command creates a metacard in the catalog, but does not copy the resource to the content store. The Ingest Command requires read access to the directory being ingested. See the URL Resource Reader for configuring read permission entries to the directory.

The syntax for the ingest command is

ingest -t <transformer type> <file path>

Select the <transformer type> based on the type of file(s) ingested. Metadata will be extracted if it exists in a format compatible with the transformer. The default transformer is the XML input transformer, which supports the metadata schema catalog:metacard. To see a list of all transformers currently installed, and the file types supported by each, run the catalog:transformers command.

For more information on the schemas and file types(mime-types) supported by each transformer see the Input Transformers.

The <file path> is relative to the <DDF_HOME> directory. This can be the path to a file or a directory containing the desired files.

Note	Windows Users On Windows, put the file path in quotes: `"path/to/file"`.

Successful command line ingest operations are accompanied with messaging indicating how many files were ingested and how long the operations took. The ingest command also prints which files could not be ingested with additional details recorded in the ingest log. The default location of the log is <DDF_HOME>/data/log/ingest_error.log.

9.1.2. User Interface Ingest

Files can also be ingested directly from Intrigue.

Warning

The Intrigue uploader is intended for the upload of products (such as images or documents), not metadata files (such as Metacard XML). A user will not be able to specify which input transformer is used to ingest the document.

See Ingesting from Intrigue for details.

9.1.3. Content Directory Monitor Ingest

The Catalog application contains a Content Directory Monitor feature that allows files placed in a single directory to be monitored and ingested automatically. For more information about configuring a directory to be monitored, see Configuring the Content Directory Monitor.

Files placed in the monitored directory will be ingested automatically. If a file cannot be ingested, they will be moved to an automatically-created directory named .errors. More information about the ingest operations can be found in the ingest log. The default location of the log is <DDF_HOME>/data/log/ingest_error.log. Optionally, ingested files can be automatically moved to a directory called .ingested.

9.1.4. External Methods of Ingesting Data

Third-party tools, such as cURL.exe and the Chrome Advanced Rest Client , can be used to send files to DDF for ingest.

Windows Example

curl -H "Content-type: application/json;id=geojson" -i -X POST -d @"C:\path\to\geojson_valid.json" https://{FQDN}:{PORT}/services/catalog

*NIX Example

curl -H "Content-type: application/json;id=geojson" -i -X POST -d @geojson_valid.json https://{FQDN}:{PORT}/services/catalog

Where:
-H adds an HTTP header. In this case, Content-type header application/json;id=geojson is added to match the data being sent in the request.
-i requests that HTTP headers are displayed in the response.
-X specifies the type of HTTP operation. For this example, it is necessary to POST (ingest) data to the server.
-d specifies the data sent in the POST request. The @ character is necessary to specify that the data is a file.

The last parameter is the URL of the server that will receive the data.

This should return a response similar to the following (the actual catalog ID in the id and Location URL fields will be different):

Sample Response


  1
2
3
4
5
6

  HTTP/1.1 201 Created
Content-Length: 0
Date: Mon, 22 Apr 2015 22:02:22 GMT
id: 44dc84da101c4f9d9f751e38d9c4d97b
Location: https://{FQDN}:{PORT}/services/catalog/44dc84da101c4f9d9f751e38d9c4d97b
Server: Jetty(7.5.4.v20111024)

Use a web browser to verify a file was successfully ingested. Enter the URL returned in the response’s HTTP header in a web browser. For instance in our example, it was /services/catalog/44dc84da101c4f9d9f751e38d9c4d97b. The browser will display the catalog entry as XML in the browser.
Verify the catalog entry exists by executing a query via the OpenSearch endpoint.
Enter the following URL in a browser /services/catalog/query?q=ddf. A single result, in Atom format, should be returned.

A resource can also be ingested with metacard metadata associated with it using the multipart/mixed content type.

Example

curl -k -X POST -i -H "Content-Type: multipart/mixed" -F parse.resource=@/path/to/resource -F parse.metadata=@/path/to/metacard https://{FQDN}:{PORT}/services/catalog

More information about the ingest operations can be found in the ingest log. The default location of the log is <DDF_HOME>/data/log/ingest_error.log.

9.1.5. Creating And Managing System Search Forms Through Karaf

System search provide a way to execute queries with pre-defined templates and search criteria. System search forms are loaded via the system and are read-only. This command allows an administrator to ingest, modify or remove system search forms within the system.

Loading Forms With Defaults

forms:load

Loading Forms With Overrides

forms:load --formsDirectory "/etc/forms" --forms "forms.json" --results "results.json"

Where:
-formsDirectory Specifies the directory in which the forms JSON and XML will reside

-results Specifies the file name of the results.json file

-forms Specifies the file name of the forms.json file

It’s important to note that forms:load will fallback to the system default location for forms, results and the forms directory. The defaults are as follows:

formsDirectory: "/etc/forms"
forms: "forms.json"
results: "results.json"

Example search forms and result form data can be found in <DDF_HOME>/etc/forms/readme.md.

Managing Forms

In addition to ingesting new system forms into the system, we provide the capability to manage the forms, view the forms and remove them.

Viewing All Forms

forms:manage --list

Removing Single Form

forms:manage --remove-single "METACARD_ID"

Removing All Forms

forms:manage --remove-all

Where:
-list Displays the titles and IDs of all system forms in the system

-remove-single Takes in a metacard ID as an argument and removes it

-remove-all Removes all system forms from the system

9.1.6. Other Methods of Ingesting Data

The DDF provides endpoints for integration with other data systems and to further automate ingesting data into the catalog. See Endpoints for more information.

9.2. Validating Data

Configure DDF to perform validation on ingested documents to verify the integrity of the metadata brought into the catalog.

Isolate metacards with data validation issues and edit the metacard to correct validation errors. Additional attributes can be added to metacards as needed.

9.2.1. Validator Plugins on Ingest

When Enforce Errors is enabled within the Admin Console, validator plugins ensure the data being ingested is valid. Below is a list of the validators run against the data ingested.

Note

Enforcing errors:

Navigate to the Admin Console.
Select the System tab.
Select the Configuration tab.
Select Metacard Validation Marker Plugin.
1. If Enforce errors is checked, these validators below will be run on ingest.
2. If Enforce errors is not checked, these validators below will not be run on ingest.

9.2.1.1. Validators run on ingest

TDF Schema Validation Service: This service validates a TDO against a TDF schema.
Size Validator: Validates the size of an attribute’s value(s).
Range Validator: Validates an attribute’s value(s) against an inclusive numeric range.
Enumeration Validator: Validates an attribute’s value(s) against a set of acceptable values.
Future Date Validator: Validates an attribute’s value(s) against the current date and time, validating that they are in the future.
Past Date Validator: Validates an attribute’s value(s) against the current date and time, validating that they are in the past.
ISO3 Country Code Validator: Validates an attribute’s value(s) against the ISO_3166-1 Alpha3 country codes.
Pattern Evaluator: Validates an attribute’s value(s) against a regular expression.
Required Attributes Metacard Validator: Validates that a metacard contains certain attributes.
Duplication Validator: Validates metacard against the local catalog for duplicates based on configurable attributes.
Relationship Validator: Validates values that an attribute must have, can only have, and/or can’t have.
Metacard WKT Validator: Validates a location metacard attribute (WKT string) against valid geometric shapes.

9.2.2. Configuring Schematron Services

DDF uses Schematron Validation to validate metadata ingested into the catalog.

Custom schematron rulesets can be used to validate metacard metadata. Multiple services can be created, and each service can have multiple rulesets associated with it. Namespaces are used to distinguish services. The root schematron files may be placed anywhere on the file system as long as they are configured with an absolute path. Any root schematron files with a relative path are assumed to be relative to <DDF_HOME>/schematron.

Tip	Schematron files may reference other schematron files using an include statement with a relative path. However, when using the document function within a schematron ruleset to reference another file, the path must be absolute or relative to the DDF installation home directory.

Schematron validation services are configured with a namespace and one or more schematron rulesets. Additionally, warnings may be suppressed so that only errors are reported.

To create a new service:

Navigate to the Admin Console.
Select the Catalog.
Select Configuration.
Ensure that catalog-schematron-plugin is started.
Select Schematron Validation Services.

9.2.3. Viewing Invalid Metacards

To view invalid metacards, query for them through Intrigue. Viewing will require DDF-administrator privileges, if Catalog Federation Strategy is configured to filter invalid metacards.

Navigate to Intrigue (https://{FQDN}:{PORT}/search).
Select Advanced Search.
Change the search property to metacard-tags.
Change the value of the property to invalid.
Select Search.

9.2.4. Manually Editing Attributes

For small numbers of metacards, or for metacards ingested without overrides, attributes can be edited directly.

Warning

Metacards retrieved from connected sources or from a fanout proxy will appear to be editable but are not truly local so changes will not be saved.

Navigate to Intrigue.
Search for the metacard(s) to be updated.
Select the metacards to be updated from the results list.
Select Summary or Details.
Select Actions from the Details view.
Select Add.
Select attribute from the list of available attributes.
Add any values desired for the attribute.

9.2.5. Injecting Attributes

To create a new attribute, it must be injected into the metacard before it is available to edit or override.

Injections are defined in a JSON-formatted file See Developing Attribute Injections for details on creating an attribute injection file.

9.2.6. Overriding Attributes

Automatically change the value of an existing attribute on ingest by setting an attribute override.

Note	Attribute overrides are available for the following ingest methods: Content Directory Monitor. Confluence source.

Navigate to the Admin Console.
Select the Catalog application.
Select Configuration.
Select the configuration for the desired ingest method.
1. Catalog Content Directory Monitor.
2. Confluence Connected Source.
3. Confluence Federated Source.
Select Attribute Overrides.
Enter the key-value pair for the attribute to override and the value(s) to set.

9.3. Backing Up the Catalog

To backup local catalog records, a Catalog Backup Plugin is available. It is not installed by default for performance reasons.

See Catalog Backup Plugin for installation and configuration instructions).

9.4. Removing Expired Records from the Catalog

DDF has many ways to remove expired records from the underlying Catalog data store. Nevertheless, the benefits of data standardization is that an attempt can be made to remove records without the need to know any vendor-specific information. Whether the data store is a search server, a No-SQL database, or a relational database, expired records can be removed universally using the Catalog API and the Catalog Commands.

9.5. Migrating Data

Data migration is the process of moving metacards from one catalog provider to another. It is also the process of translating metadata from one format to another. Data migration is necessary when a user decides to use metadata from one catalog provider in another catalog provider.

The process for changing catalog providers involves first exporting the metadata from the original catalog provider and ingesting it into another.

From the Command Console, use these commands to export data from the existing catalog and then import into the new one.

catalog:export: Exports metacards, history, and their associated resources from the current Catalog to an auto-generated file inside <DDF_HOME>.
Use the catalog:export --help command to see all available options.
catalog:import <FILE_NAME>: Imports Metacards and history into the current Catalog.
Use the catalog:import --help command to see all available options.

9.6. Automatically Added Metacard Attributes

This section describes how attributes are automatically added to metacards.

9.6.1. Attributes Added on Ingest

A metacard is first created and populated by parsing the ingested resource with an Input Transformer.
Then Attributes Are Injected, Default Attribute Types are applied, and Attribute are Overridden.
Finally the metacard is passed through a series of Pre-Authorization Plugins and Pre-Ingest Plugins.

Ingest Attribute Flow

9.6.1.1. Attributes Added by Input Transformers

Input Transformers create and populate metacards by parsing a resource. See File Format Specific Attributes to see the attributes used for specific file formats.

DDF chooses which input transformer to use by:

Resolving the mimetype for the resource.
Gathering all of the input transformers associated with the resolved mimetype. See Supported File Formats for a list of supported mimetypes.
Iterating through the transformers until a successful transformation is performed.

The first transformer that can successfully create a metacard from the ingested resource is chosen. If no transformer can successfully transform the resource, the ingest process fails.

Important

Each of the ingest methods have their own subtle differences when resolving the resource’s mimetype/input transformer.
For example: a resource ingested through Intrigue may not produce the same metacard attributes as the same resource ingested through the Content Directory Monitor.

9.6.1.2. Attributes Added by Attribute Injection

Attribute Injection is the act of adding attributes to a metacard’s Metacard Type. A Metacard Type indicates the attributes available for a particular metacard, and is created at the same time as the metacard.

Note	Attribute values can only be set/modified if the attribute exists in the metacard’s metacard type. Attributes are initially injected with blank values. However, if an attempt is made to inject an attribute that already exists, the attribute will retain the original value.

See Catalog Taxonomy Definitions for a list of attributes injected by default.
See Developing Attribute Injections to learn how to configure attribute injections.

9.6.1.3. Attributes Added by Default Attribute Types

Developing Default Attribute Types is a configurable way to assign default values to a metacard’s attributes.

Note that the attribute must be part of the metacard’s Metacard Type before it can be assigned a default value.
See Attributes Added By Attribute Injection for more information about injecting attributes into the metacard type.

9.6.1.4. Attributes Added by Attribute Overrides (Ingest)

Attribute Overriding is the act of replacing existing attribute values with a new value.

Attribute overrides can be configured for the Content Directory Monitor.

Note that the attribute must be part of the metacard’s Metacard Type before it can be overridden.
See Attributes Added By Attribute Injection for more information about injecting attributes into the metacard type.

9.6.1.5. Attributes Added by Pre-Authorization Plugins

The Pre-Authorization Plugins provide an opportunity to take action before any security rules are applied.

The Metacard Ingest Network Plugin is a configurable plugin that allows the conditional insertion of new attributes on metacards during ingest based on network information from the ingest request. See Configuring the Metacard Ingest Network Plugin for configuration details.

9.6.1.6. Attributes Added by Pre-Ingest Plugins

The Pre-Ingest Plugins are responsible for setting attribute fields on metacards before they are stored in the catalog.

The Expiration Date Pre-Ingest Plugin adds or updates expiration dates which can be used later for archiving old data.
The Geocoder Plugin is responsible for populating the metacard’s Location.COUNTRY_CODE attribute if the metacard has an associated location. If the metacard’s country code is already populated, the plugin will not override it.
The Identification Plugin assigns IDs to registry metacards and adds/updates IDs on create and update.
The Metacard Groomer plugin adds/updates IDs and timestamps to the created metacard.

9.6.2. Attributes Added on Query

Metacards resulting from a query will undergo Attribute Injection, then have their Attributes Overridden.

9.6.2.1. Attributes Added by Attribute Overrides (Query)

Attribute Overriding is the act of replacing existing attribute values with a new value.

Attribute overrides can be configured for query results from the following Sources:

Federated Source For Atlassian Confluence.
CSW Specification Profile Federated Source.
GMD CSW Federated Source.

A new workspace, by default called New Workspace, will be created containing only the new search.
Rename the workspace, if desired.
Select the Save icon next to the workspace name.

Search Types

Text: Perform a minimal textual search that is treated identically to a Basic search with only Text specified.

Basic: Define a Text, Temporal, Spatial, or Type Search.

Text Search Details: Searches across all textual data of the targeted data source. Text search capabilities include:

Search for an exact word, such as Text = apple : Returns items containing the word "apple" but not "apples". Matching occurs on word boundaries.
Search for the existence of items containing multiple words, such as Text = apple orange : Returns items containing both "apple" and "orange" words. Words can occur anywhere in an item’s metadata.
Search using wildcards, such as Text = foo* : Returns items containing words like "food", "fool", etc..

Wildcards should only be used for single word searches, not for phrases.

Warning

When searching with wildcards, do not include the punctuation at the beginning or the end of a word. For example, search for Text = ca* instead of Text = -ca* when searching for words like "cat", "-cat", etc.. and search for Text = *og instead of Text = *og. when searching for words like "dog", "dog.", etc..

Text searches are by default case insensitive, but case sensitive searches are an option.

Temporal Search Details: Search based on absolute time of the created, modified, or effective date.
- Any: Search without any time restrictions (default).
- After: Search records after a specified time.
- Before: Search records before a specified time.
- Between: Set a beginning and end time to search between.
- Relative: Search records relative to the current time.

Spatial Search Details

Search by latitude/longitude (decimal degrees or degrees minutes seconds), USNG/MGRS, or UTM
Search by entering a Keyword for a region, country, or city in the Location section of the query builder.

To search using a line, polygon, point-radius, or bounding box, select the shape to draw, then select Draw.

Note

Intersecting Polygon Searchs

If a self intersecting polygon is used to perform a geographic search, the polygon will be converted into a non-intersection one via a convex hull conversion. In the example below the blue line shows the original self intersecting search polygon and the red line shows the converted polygon that will be used for the search. The blue dot shows a search result that was not within the original polygon but was returned because it was within the converted polygon.

Figure 2. Self Intersecting Polygon Conversion Example

Type Search Details
- Search for specific content types.

Advanced: Advanced Query Builder can be used to create more specific searches than can be done through the other methods.
- Advanced Query Builder Details
  - Operator: If 'AND' is used, all the filters in the branch have to be true for this branch to be true. If 'OR' is used, only one of the filters in this branch has to be true for this branch to be true.
  - Property: Property to compare against.
  - Comparison: How to compare the value for this property against the provided value. Depending on the type of property selected, various comparison values will be available. See Types of Comparators
  - Search Terms: The value for the property to use during comparison.
  - Sorting: Sort results by relevance, distance, created time, modified time or effective time.
  - Sources: Perform an enterprise search (the local Catalog and all federated sources) or search specific sources.
- Advanced Query Builder Comparators
  - Textual:
    
    CONTAINS: Equivalent to Basic Text Search with Matchcase set to No.
    
    MATCHCASE: Equivalent to Basic Text Search with Matchcase set to Yes.
    
    =: Matches if an attribute is precisely equal to that search term.
    
    NEAR: Performs a fuzzy proximity-based textual search. A NEAR query of "car street" within 3 will match a sample text of the blue car drove down the street with the red building because performing three word deletions in that phrase (drove, down, the) causes car and street to become adjacent.
    
    EMPTY: Search records when the attribute itself does not exist or when the attribute value is null.
    
    More generally, a NEAR query of "A B" within N matches a text document if you can perform at most N insertions/deletions to your document and end up with A followed by B.
    
    It is worth noting that "street car" within 3 will not match the above sample text because it is not possible to match the phrase "street car" after only three insertions/deletions. "street car" within 5 will match, though, as you can perform three word deletions to get "car street", one deletion of one of the two words, and one insertion on the other side.
    
    If multiple terms are used in the phrase, then the within amount specifies the total number of edits that can be made to attempt to make the full phrase match. "car down street" within 2 will match the above text because it takes two word deletions (drove, the) to turn the phrase car drove down the street into car down street.
  - Temporal:
    
    BEFORE: Search records before a specified time.
    
    AFTER: Search records after a specified time.
    
    RELATIVE Search records relative to the current time.
    
    EMPTY: Search records when the attribute itself does not exist or when the attribute value is null.
  - Spatial:
    
    INTERSECTS: Gives a component with the same functionality as Basic Spatial Search.
    
    EMPTY: Search records when the attribute itself does not exist or when the attribute value is null.
  - Numeric:
    
    >: Search records with field entries greater than the specified value.
    
    >=: Search records with field entries greater than or equal to the specified value.
    
    =: Search records with field entries equal to the specified value.
    
    <=: Search records with field entries less than or equal to the specified value.
    
    RANGE: Search records between the two specified values (inclusive).
    
    <: Search records with field entries less than the specified value.
    
    EMPTY: Search records when the attribute itself does not exist or when the attribute value is null.

11. Using the Simple Search

The DDF Simple Search UI application provides a low-bandwidth option for searching records in the local Catalog (provider) and federated sources. Results are returned in HTML format.

11.1. Search

The Input form allows the user to specify keyword, geospatial, temporal, and type query parameters. It also allows the user to select the sources to search and the number of results to return.

11.1.1. Search Criteria

Enter one or more of the available search criteria to execute a query:

Keyword Search: A text box allowing the user to enter a textual query. This supports the use of (*) wildcards. If blank, the query will contain a contextual component.
Temporal Query: Select from any, relative, or absolute. Selecting Any results in no temporal restrictions on the query, selecting relative allows the user to query a period from some length of time in the past until now, and selecting absolute allows the user to specify a start and stop date range.
Spatial Search: Select from any, point-radius, and bounding box. Selecting Any results in no spatial restrictions on the query, selecting point-radius allows the user to specify a lat/lon and radius to search, and selecting a bounding box allows the user to specify an eastern, western, southern and northern boundary to search within.
Type Search: Select from any, or a specific type. Selecting Any results in no type restrictions on the query, and Selecting Specific Types shows a list of known content types on the federation, and allows the user to select a specific type to search for.
Sources: Select from none, all sources, or specific sources. Selelcting None results in querying only the local provider, Selecting All Sources results in an enterprise search where all federations are queried, and selecting Specific Sources allows the user to select which sources are queried.
Results per Page: Select the number of results to be returned by a single query.

11.1.2. Results

The table of results shows the details of the results found, as well as a link to download the product if applicable.

Result Table: Provides the list of properties and associated values of a single search result.
Metadata: The metadata, when expanded, displays a tree structure representing the result’s custom metadata.

Integrating

Warning

If integrating with a Highly Available Cluster of DDF, see High Availability Guidance.

DDF is structured to enable flexible integration with external clients and into larger component systems.

If integrating with an existing installation of DDF, continue to the following sections on endpoints and data/metadata management.

If a new installation of DDF is required, first see the Managing section for installation and configuration instructions, then return to this section for guidance on connecting external clients.

If you would like to set up a test or demo installation to use while developing an external client, see the Quick Start Tutorial for demo instructions.

For troubleshooting and known issues, see the Release Notes .

12. Endpoints

Federation with DDF is primarily accomplished through Endpoints accessible through http(s) requests and responses.

Note	Not all installations will expose all available endpoints. Check with DDF administrator to confirm availability of these endpoints.

12.1. Ingest Endpoints

Ingest is the process of getting data and/or metadata into the DDF catalog framework.

These endpoints are provided by DDF to be used by integrators to ingest content or metadata.

Catalog REST Endpoint: Uses REST to interact with the catalog.
CSW Endpoint: Searches collections of descriptive information (metadata) about geospatial data and services.
FTP Endpoint: Ingests files directly into the DDF catalog using the FTP protocol.

12.2. CRUD Endpoints

To perform CRUD (Create, Read, Update, Delete) operations on data or metadata in the catalog, work with one of these endpoints.

Catalog REST Endpoint: Uses REST to interact with the catalog.
CSW Endpoint: Searches collections of descriptive information (metadata) about geospatial data and services.
Queries Endpoint: To perform CRUD (Create, Read, Update, Delete) operations on query metacards in the catalog, work with one of these endpoints.

12.3. Query Endpoints

Query data or metadata stored within an instance of DDF using one of these endpoints.

CSW Endpoint: Searches collections of descriptive information (metadata) about geospatial data and services.
OpenSearch Endpoint: Sends query parameters and receives search results.

12.4. Content Retrieval Endpoints

To retrieve content from an instance of DDF, use one of these endpoints.

Catalog REST Endpoint: Uses REST to interact with the catalog.

12.5. Pub-Sub Endpoints

These endpoints provide publication and subscription services to allow notifications when certain events happen within DDF.

CSW Endpoint: Searches collections of descriptive information (metadata) about geospatial data and services.

12.6. Endpoint Details

12.6.1. Catalog REST Endpoint

The Catalog REST Endpoint allows clients to perform operations on the Catalog using REST, a simple architectural style that performs communication using HTTP.

Bulk operations are not supported: for all RESTful CRUD commands, only one metacard ID is supported in the URL.

The Catalog REST Endpoint can be used for one or more of these operations on an instance of DDF:

Ingest metacards or resources into the DDF catalog.
Retrieve metacards or resources from the catalog.
Update metacards or resources in the catalog.
Delete resources and metadata from the catalog.
Get information about configured sources.

This example metacard can be used to test the integration with DDF.

</metacard>

12.6.1.1. Catalog REST Create Operation Examples

The REST endpoint can be used to upload resources as attachments.

Send a POST request with the input to be ingested contained in the HTTP request body to the endpoint.

Create Request URL

https://<FQDN>:<PORT>/services/catalog/

Example Create Request

  POST /services/catalog?transform=xml HTTP/1.1
Host: <FQDN>:<PORT>
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW
Cache-Control: no-cache

------WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="parse.resource"; filename=""
Content-Type:


------WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="parse.metadata"; filename=""
Content-Type:


------WebKitFormBoundary7MA4YWxkTrZu0gW--

The create and update methods both support the multipart mime format. If only a single attachment exists, it will be interpreted as a resource to be parsed, which will result in a metacard and resource being stored in the system.

If multiple attachments exist, then the REST endpoint will assume that one attachment is the actual resource (attachment should be named parse.resource) and the other attachments are overrides of metacard attributes (attachment names should follow metacard attribute names). In the case of the metadata attribute, it is possible to also have the system transform that metadata and use the results of that to override the metacard that would be generated from the resource (attachment should be named parse.metadata).

Create Success

If the ingest is successful, a status of 201 Created will be returned, along with the Metacard ID in the header of the response.

Note	Request with Non-XML Data If a request with non-XML data is sent to the Catalog REST endpoint, the metacard will be created but the resource will be stored in the `metadata` field. This could affect discoverability.

If content or metadata is not ingested successfully, check for these error messages.

Table 33. Create Error Responses
Status Code	Error Message	Possible Causes
`400 Bad Request`	`<pre>Error while storing entry in catalog: </pre>`	Malformed XML Response: If the XML being ingested has formatting errors.
`400 Bad Request`	`<pre>Error while storing entry in catalog: </pre>`	Request with Unknown Schema: If ingest is attempted with a schema that is unknown, unsupported, or not configured by the endpoint, DDF creates a generic resource metacard with the provided XML as content for the `metadata` XML field in the metacard.

12.6.1.2. Catalog REST Read Operation Examples

The read operation can be used to retrieve metadata in different formats.

Send a GET request to the endpoint.
Optionally add a transform query parameter to the end of the URL with the transformer to be used (such as transform=kml). By default, the response body will include the XML representation of the Metacard.

Read Request URL

https://<FQDN>:<PORT>/services/catalog/<metacardId>

If successful, a status of 200 OK will be returned, along with the content of the metacard requested.

12.6.2. CSW Endpoint

The CSW endpoint enables a client to search collections of descriptive information (metadata) about geospatial data and services.

The CSW endpoint supports metadata operations only.

For more information about the Catalogue Services for Web (CSW) standard .

The CSW Endpoint can be used for one or more of these operations on an instance of DDF:

Ingest metadata into the DDF catalog.
Read metacards from the catalog.
Update metadata in the catalog.
Publish and/or subscribe to catalog events.
Delete metadata from the catalog.
Get capabilities of the catalog and the URLs used to access.

Note	Sample Responses May Not Match Actual Responses Actual responses may vary from these samples, depending on your configuration. Send a GET or POST request to obtain an accurate response.

12.6.2.1. CSW Endpoint Create Examples

Metacards are ingested into the catalog via the Insert sub-operation.

The schema of the record needs to conform to a schema of the information model that the catalog supports.

Send a POST request to the CSW endpoint URL.

CSW Endpoint Ingest URL

12.6.2.2. CSW Endpoint Query Examples

To query through the CSW Enpoint, send a POST request to the CSW endpoint.

CSW Endpoint Query URL

https://<FQDN>:<PORT>/services/csw

Within the body of the request, include a GetRecords operation to define the query. Define the service and version to use (CSW, 2.0.2). The output format must be application/xml. Specify the output schema. (To get a list of supported schemas, send a Get Capabilities request to the CSW endpoint.)

Querying a Specific Source with the CSW Endpoint

To query a Specific Source, specify a query for a source-id. To find a valid source-id , send a Get Capabilities request. Configured sources will be listed in the FederatedCatalogs section of the response.

Note	The `DistributedSearch` element must be specific with a `hopCount` greater than 1 to identify it as a federated query, otherwise the `source-id`'s will be ignored.

Querying by UTM Coordinates

UTM coordinates can be used when making a CSW GetRecords request using an ogc:Filter. UTM coordinates should use EPSG:326XX`as the `srsName where XX is the zone within the northern hemisphere. UTM coordinates should use EPSG:327XX as the srsName where XX is the zone within the southern hemisphere.

Note	UTM coordinates are only supported with requests providing an `ogc:Filter`, but not with CQL as there isn’t a way to specify the UTM `srsName` in CQL.

Updating Individual Attributes

Within the csw:Transaction element, use the csw:RecordProperty to update individual metacard attributes.

Use the Name element to specify the name of the record property to be updated and set the Value element to the value to update in the record. The values in the Update will completely replace those that are already in the record.

  <csw:RecordProperty>
    <csw:Name>title</csw:Name>
    <csw:Value>Updated Title</csw:Value>
</csw:RecordProperty>

Removing Attributes

To remove a non-required attribute, send the csw:Name without a csw:Value.


  1
2
3

  <csw:RecordProperty>
    <csw:Name>title</csw:Name>
</csw:RecordProperty>

Required attributes are set to a default value if no Value element is provided.

Table 41. `RecordProperty` Default Values
Property	Default Value
`metadata-content-type`	Resource
`created`	current time
`modified`	current time
`effective`	current time
`metadata-content-type-version`	myVersion
`metacard.created`	current time
`metacard.modified`	current time
`metacard-tags`	resource, VALID
`point-of-contact`	system@localhost
`title`	current time

Use a csw:Constraint to specify the metacard ID. The constraint can be an OGC Filter or a CQL query.

12.6.2.4. CSW Endpoint Publication/Subscription Examples

The subscription GetRecords operation is very similar to the GetRecords operation used to search the catalog but it subscribes to a search and sends events to a ResponseHandler endpoint as metacards are ingested matching the GetRecords request used in the subscription. The ResponseHandler must use the https protocol and receive a HEAD request to poll for availability and POST/PUT/DELETE requests for creation, updates, and deletions. The response to a GetRecords request on the subscription url will be an acknowledgement containing the original GetRecords request and a requestId. The client will be assigned a requestId (URN).

A Subscription listens for events from federated sources if the DistributedSearch element is present and the catalog is a member of a federation.

Adding a Subscription

Send a POST request to the CSW endpoint.

12.6.2.6. CSW Endpoint Get Capabilities Examples

The GetCapabilities operation describes the operations the catalog supports and the URLs used to access those operations. The CSW endpoint supports both HTTP GET and HTTP POST requests for the GetCapabilities operation. The response to either request will always be a csw:Capabilities XML document. This XML document is defined by the CSW-Discovery XML Schema .

CSW Endpoint GetCapabilities URL for GET request

https://<FQDN>:<PORT>/services/csw?service=CSW&version=2.0.2&request=GetCapabilities

Alternatively, send a POST request to the root CSW endpoint URL.

CSW Endpoint GetCapabilities URL for GET request

$https://<FQDN>:<PORT>/services/csw

Include an XML message body with a GetCapabilities element.

GetCapabilities Sample Request

<?xml version="1.0" ?>
<csw:GetCapabilities
  xmlns:csw="http://www.opengis.net/cat/csw/2.0.2"
  service="CSW"
  version="2.0.2" >

12.6.3. FTP Endpoint

The FTP endpoint provides a method for ingesting files directly into the DDF catalog using the FTP protocol.

The FTP endpoint can be accessed from any FTP client of choice. Some common clients are FileZilla, PuTTY, or the FTP client provided in the terminal. The default port number is 8021. If FTPS is enabled with 2-way TLS, a client that supports client authentication is required.

12.6.3.1. FTP Endpoint Create Examples

To ingest files into DDF send an FTP PUT request to the DDF server.

FTP Endpoint URL

ftp://<FQDN>:<PORT>

12.6.3.2. FTP Endpoint Rename Command

The FTP endpoint also supports renaming files as they are ingested with the FTP RNTO operation.

Files named with a leading ., such as .<FILENAME>, are held by DDF without being ingested until the rename command is sent.

PUT Command Example

PUT .<FILENAME>.txt

Rename Command Example

rename .<NEW_FILENAME>.txt

The endpoint will complete the ingest process when the rename command is sent. The filename on the original file system will NOT be changed.

12.6.4. OpenSearch Endpoint

The OpenSearch Endpoint enables a client to send query parameters and receive search results. This endpoint uses the input query parameters to create an OpenSearch query. The client does not need to specify all of the query parameters, only the query parameters of interest.

The OpenSearch specification defines a file format to describe an OpenSearch endpoint. This file is XML-based and is used to programatically retrieve a site’s endpoint, as well as the different parameter options a site holds. The parameters are defined via the OpenSearch and CDR IPT Specifications.

12.6.4.1. OpenSearch Contextual Queries

To use the OpenSearch endpoint for a query, send a GET request with the query options as parameters

OpenSearch Query URL

https://<FQDN>:<PORT>/services/catalog/query?<NAME>="<VALUE>"

Table 44. OpenSearch Parameter List
OpenSearch Element	HTTPS Parameter	Possible Values	Comments
`searchTerms`	`q`	URL-encoded, space-delimited list of search terms	Complex contextual search string.
`count`	`count`	Integer >= 0	Maximum # of results to retrieve. default: `10`
`startIndex`	`start`	integer > 0	Index of first result to return. This value uses a one-based index for the results. default: `1`
`format`	`format`	Requires a transformer shortname as a string, possible values include, when available, `atom`, `html`, and `kml`. See Query Response transformers for more possible values.	Defines the format that the return type should be in. default: `atom`

Sample OpenSearch Textual Query

https://<FQDN>:<PORT>/services/catalog/query?q="Aliquam"&count=20

12.6.4.1.1. Complex OpenSearch Contextual Query Format

The OpenSearch Endpoint supports the following operators: AND, OR, and NOT. These operators are case sensitive. Implicit ANDs are also supported.

Use parentheses to change the order of operations. Use quotes to group keywords into literal expressions.

See the OpenSearch specification for more syntax specifics.

OpenSearch Endpoint Complex Query Example

https://<FQDN>:<PORT>/services/catalog/query?q='cat OR dog'

12.6.4.2. OpenSearch Temporal Queries

Queries can also specify a start and end time to narrow results.

Table 45. OpenSearch Temporal Parameters
OpenSearch Element	HTTPS Parameter	Possible Values	Comments
`start`	`dtstart`	RFC-3399-defined value:`YYYY-MM-DDTHH:mm:ssZ` or `yyyy-MM-dd’T’HH:mm:ss.SSSZZ`	Specifies the beginning of the time slice of the search. Default value of "1970-01-01T00:00:00Z" is used when `dtend` is specified but `dtstart` is not specified.
`end`	`dtend`	RFC-3399-defined value:`YYYY-MM-DDTHH:mm:ssZ` or `yyyy-MM-dd’T’HH:mm:ss.SSSZZ`	Specifies the ending of the time slice of the search Current GMT date/time is used when `dtstart` is specified but `dtend` is not specified.

OpenSearch Temporal Query Example

https://<FQDN>:<PORT>/services/catalog/query?q='*'&dtstart=2020-04-02T00:00:00Z&dtend=2020-04-02T18:00:00Z

Note	The start and end temporal criteria must be of the format specified above. Other formats are currently not supported. Example: `2020-04-02T12:00:00.111-04:00`. The start and end temporal elements are based on modified timestamps for a metacard.

12.6.4.3. OpenSearch Geospatial Queries

Query by location.

Use geospatial query parameters to create a geospatial INTERSECTS query, where INTERSECTS means geometries that are not DISJOINT to the given geospatial parameters.

Table 46. Opensearch Geospatial Parameters
OpenSearch Element	HTTPS Parameter	Possible Values	Comments
`lat`	`lat`	`EPSG:4326 (WGS84)` decimal degrees	Used in conjunction with the `lon` and `radius` parameters.
`lon`	`lon`	`EPSG:4326 (WGS84)` decimal degrees	Used in conjunction with the `lat` and `radius` parameters.
`radius`	`radius`	`EPSG:4326 (WGS84)` meters along the Earth’s surface > 0	Specifies the search distance in meters from the `lon`,`lat` point. Used in conjunction with the `lat` and `lon` parameters. default: `5000`
`polygon`	`polygon`	Comma-delimited list of lat/lon (`EPSG:4326 (WGS84)` decimal degrees) pairs, in clockwise order around the polygon, where the last point is the same as the first in order to close the polygon. (e.g. `-80,-170,0,-170,80,-170,80,170,0,170,-80,170,-80,-170`)	According to the OpenSearch Geo Specification this is deprecated. Use the `geometry` parameter instead.
`box`	`bbox`	4 comma-delimited `EPSG:4326 (WGS84)` decimal degrees coordinates in the format West,South,East,North
`geometry`	`geometry`	WKT Geometries Examples: `POINT(10 20)` where 10 is the longitude and 20 is the latitude. `POLYGON ( ( 30 10, 10 20, 20 40, 40 40, 30 10 ) )`. 30 is longitude and 10 is latitude for the first point. `MULTIPOLYGON ( ( (40 40, 20 45, 45 30, 40 40) ), ( (20 35, 10 30, 10 10, 30 5, 45 20, 20 35), (30 20, 20 15, 20 25, 30 20) ) )` `GEOMETRYCOLLECTION(POINT(4 6),LINESTRING(4 6,7 10))`	Make sure to repeat the starting point as the last point to close the polygon.

12.6.4.4. Additional OpenSearch Query Parameters

The OpenSearch Endpoint can also use these additional parameters to refine queries

Table 47. OpenSearch Query Extensions
OpenSearch Element	HTTPS Parameter	Possible Values	Comments
`sort`	`sort`	`<sbfield>:<sborder>` where `<sbfield>` is `date` or `relevance` `<sborder>` is `asc` or `desc`	`<sborder>` is optional but has a value of `asc` or `desc` (default is `desc`). However, when `<sbfield>` is `relevance`, `<sborder>` must be `desc`. Sorting by `date` will sort the results by the `effective` date. default: `relevance:desc`
`maxResults`	`mr`	Integer >= 0	Maximum # of results to return. If `count` is also specified, the `count` value will take precedence over the `maxResults` value. default: `1000`
`maxTimeout`	`mt`	Integer > 0	Maximum timeout (milliseconds) for query to respond. default: `300000` (5 minutes)
`dateOffset`	`dtoffset`	Integer > 0	Specifies an offset (milliseconds), backwards from the current time, to search on the modified time field for entries.
`type`	`type`	Any valid datatype (e.g. `Text`)	Specifies the type of data to search for.
`version`	`version`	Comma-delimited list of strings (e.g. 20,30)	Version values for which to search.
`selector`	`selector`	Comma-delimited list of XPath string selectors (e.g. `//namespace:example`, //example`)	Selectors to narrow the query.

Table 48. Federated Search
OpenSearch Element	HTTPS Parameter	Possible Values	Comments
`routeTo`	`src`	Comma-delimited list of site names to query. Varies depending on the names of the sites in the federation. `local` specifies to query the local site.	If `src` is not provided, the default behavior is to execute an enterprise search to the entire federation.

12.6.5. Queries Endpoint

The queries endpoint enables an application to create, retrieve, update, and delete query metacards.

Query metacards represent queries within the UI. A query metacard is what is persisted in the data store.

The queries endpoint can be used for one or more of these operations on an instance of DDF:

Create query metacards and store them in the DDF catalog.
Retrieve all query metacards stored in the DDF catalog and sort them based on attribute and sort order.
Retrieve a specific query metacard stored in the DDF catalog.
Update query metacards that are stored in the DDF catalog.
Delete query metacards that are stored in the DDF catalog.

Queries Endpoint URL

https://<HOSTNAME>:<PORT>/search/catalog/internal/queries

12.6.5.1. Queries Endpoint Create Examples

To create a query metacard through the queries endpoint, send a POST request to the queries endpoint.

Developing

Developers will build or extend the functionality of the applications.

DDF includes several extension points where external developers can add functionality to support individual use cases.

DDF is written in Java and uses many open source libraries. DDF uses OSGi to provide modularity, lifecycle management, and dynamic services. OSGi services can be installed and uninstalled while DDF is running. DDF development typically means developing new OSGi bundles and deploying them to the running DDF. A complete description of OSGi is outside the scope of this documentation. For more information about OSGi, see the OSGi Alliance website .

If developing for a Highly Available Cluster of DDF, see High Availability Guidance.

13. Catalog Framework API

Catalog Architecture

Catalog Framework Architecture

The CatalogFramework is the routing mechanism between catalog components that provides integration points for the Catalog Plugins. An endpoint invokes the active Catalog Framework, which calls any configured Pre-query or Pre-ingest plug-ins. The selected federation strategy calls the active Catalog Provider and any connected or federated sources. Then, any Post-query or Post-ingest plug-ins are invoked. Finally, the appropriate response is returned to the calling endpoint.

The Catalog Framework wires all Catalog components together.

It is responsible for routing Catalog requests and responses to the appropriate target.

The Catalog Framework decouples clients from service implementations and provides integration points for Catalog Plugins and convenience methods for Endpoint developers.

13.1. Catalog API Design

The Catalog is composed of several components and an API that connects them together. The Catalog API is central to DDF’s architectural qualities of extensibility and flexibility. The Catalog API consists of Java interfaces that define Catalog functionality and specify interactions between components. These interfaces provide the ability for components to interact without a dependency on a particular underlying implementation, thus allowing the possibility of alternate implementations that can maintain interoperability and share developed components. As such, new capabilities can be developed independently, in a modular fashion, using the Catalog API interfaces and reused by other DDF installations.

13.1.1. Ensuring Compatibility

The Catalog API will evolve, but great care is taken to retain backwards compatibility with developed components. Compatibility is reflected in version numbers.

13.1.2. Catalog Framework Sequence Diagrams

Because the Catalog Framework plays a central role to Catalog functionality, it interacts with many different Catalog components. To illustrate these relationships, high-level sequence diagrams with notional class names are provided below. These examples are for illustrative purposes only and do not necessarily represent every step in each procedure.

Ingest Request Data Flow

The Ingest Service Endpoint, the Catalog Framework, and the Catalog Provider are key components of the Reference Implementation. The Endpoint bundle implements a Web service that allows clients to create, update, and delete metacards. The Endpoint calls the CatalogFramework to execute the operations of its specification. The CatalogFramework routes the request through optional PreIngest and PostIngest Catalog Plugins, which may modify the ingest request/response before/after the Catalog Provider executes the ingest request and provides the response. Note that a CatalogProvider must be present for any ingest requests to be successfully processed, otherwise a fault is returned.

This process is similar for updating catalog entries, with update requests calling the update(UpdateRequest) methods on the Endpoint, CatalogFramework, and Catalog Provider. Similarly, for deletion of catalog entries, the delete requests call the delete(DeleteRequest) methods on the Endpoint, CatalogFramework, and CatalogProvider.

13.1.2.1. Error Handling

Any ingest attempts that fail inside the Catalog Framework (whether the failure comes from the Catalog Framework itself, pre-ingest plugin failures, or issues with the Catalog Provider) will be logged to a separate log file for ease of error handling. The file is located at <DDF_HOME>/data/log/ingest_error.log and will log the Metacards that fail, their ID and Title name, and the stack trace associated with their failure. By default, successful ingest attempts are not logged. However, that functionality can be achieved by setting the log level of the ingestLogger to DEBUG (note that enabling DEBUG can cause a non-trivial performance hit).

Tip	To turn off logging failed ingest attempts into a separate file, execute the following via the command line console log:set ERROR ingestLogger

13.1.2.2. Query

Query Request Data Flow

The Query Service Endpoint, the Catalog Framework, and the CatalogProvider are key components for processing a query request as well. The Endpoint bundle contains a Web service that exposes the interface to query for Metacards. The Endpoint calls the CatalogFramework to execute the operations of its specification. The CatalogFramework relies on the CatalogProvider to execute the actual query. Optional PreQuery and PostQuery Catalog Plugins may be invoked by the CatalogFramework to modify the query request/response prior to the Catalog Provider processing the query request and providing the query response. If a CatalogProvider is not configured and no other remote Sources are configured, a fault will be returned. It is possible to have only remote Sources configured and no local CatalogProvider configured and be able to execute queries to specific remote Sources by specifying the site name(s) in the query request.

13.1.2.3. Product Retrieval

The Query Service Endpoint, the Catalog Framework, and the CatalogProvider are key components for processing a retrieve product request. The Endpoint bundle contains a Web service that exposes the interface to retrieve products, also referred to as Resources. The Endpoint calls the CatalogFramework to execute the operations of its specification. The CatalogFramework relies on the Sources to execute the actual product retrieval. Optional PreResource and PostResource Catalog Plugins may be invoked by the CatalogFramework to modify the product retrieval request/response prior to the Catalog Provider processing the request and providing the response. It is possible to retrieve products from specific remote Sources by specifying the site name(s) in the request.

13.1.2.4. Product Caching

The Catalog Framework optionally provides caching of products, so future requests to retrieve the same product will be serviced much quicker. If caching is enabled, each time a retrieve product request is received, the Catalog Framework will look in its cache (default location <DDF_HOME>/data/product-cache) to see if the product has been cached locally. If it has, the product is retrieved from the local site and returned to the client, providing a much quicker turnaround because remote product retrieval and network traffic was avoided. If the requested product is not in the cache, the product is retrieved from the Source (local or remote) and cached locally while returning the product to the client. The caching to a local file of the product and the streaming of the product to the client are done simultaneously so that the client does not have to wait for the caching to complete before receiving the product. If errors are detected during the caching, caching of the product will be abandoned, and the product will be returned to the client.

The Catalog Framework attempts to detect any network problems during the product retrieval, e.g., long pauses where no bytes are read implying a network connection was dropped. (The amount of time defined as a "long pause" is configurable, with the default value being five seconds.) The Catalog Framework will attempt to retrieve the product up to a configurable number of times (default = three), waiting for a configurable amount of time (default = 10 seconds) between each attempt, trying to successfully retrieve the product. If the Catalog Framework is unable to retrieve the product, an error message is returned to the client.

If the admin has enabled the Always Cache When Canceled option, caching of the product will occur even if the client cancels the product retrieval so that future requests will be serviced quickly. Otherwise, caching is canceled if the user cancels the product download.

13.1.2.5. Product Download Status

As part of the caching of products, the Catalog Framework also posts events to the OSGi notification framework. Information includes when the product download started, whether the download is retrying or failed (after the number of retrieval attempts configured for product caching has been exhausted), and when the download completes. These events are retrieved by the Search UI and presented to the user who initiated the download.

13.1.3. Catalog API

The Catalog API is an OSGi bundle (catalog-core-api) that contains the Java interfaces for the Catalog components and implementation classes for the Catalog Framework, Operations, and Data components.

13.1.3.1. Catalog API Search Interfaces

The Catalog API includes two different search interfaces.

Search UI Application Search Interface: The DDF Search UI application provides a graphic interface to return results and locate them on an interactive globe or map.
SSH Search Interface: Additionally, it is possible to use a client script to remotely access DDF via SSH and send console commands to search and ingest data.

13.1.3.2. Catalog Search Result Objects

Data is returned from searches as Catalog Search Result objects. This is a subtype of Catalog Entry that also contains additional data based on what type of sort policy was applied to the search. Because it is a subtype of Catalog Entry, a Catalog Search Result has all Catalog Entry’s fields such as metadata, effective time, and modified time. It also contains some of the following fields, depending on type of search, that are populated by DDF when the search occurs:

Distance: Populated when a point-radius spatial search occurs. Numerical value that indicates the result’s distance from the center point of the search.
Units: Populated when a point-radius spatial search occurs. Indicates the units (kilometer, mile, etc.) for the distance field.
Relevance: Populated when a contextual search occurs. Numerical value that indicates how relevant the text in the result is to the text originally searched for.

13.1.3.3. Search Programmatic Flow

Searching the catalog involves three basic steps:

Define the search criteria (contextual, spatial, or temporal).
1. Optionally define a sort policy and assign it to the criteria.
2. For contextual search, optionally set the fuzzy flag to true or false (the default value for the Metadata Catalog fuzzy flag is true, while the portal default value is false).
3. For contextual search, optionally set the caseSensitive flag to true (the default is that caseSensitive flag is NOT set and queries are not case sensitive). Doing so enables case sensitive matching on the search criteria. For example, if caseSensitive is set to true and the phrase is “Baghdad” then only metadata containing “Baghdad” with the same matching case will be returned. Words such as “baghdad”, “BAGHDAD”, and “baghDad” will not be returned because they do not match the exact case of the search term.
Issue a search.
Examine the results.

13.1.3.4. Sort Policies

Searches can also be sorted according to various built-in policies. A sort policy is applied to the search criteria after its creation but before the search is issued. The policy specifies to the DDF the order the Catalog search results should be in when they are returned to the requesting client. Only one sort policy may be defined per search.

There are three policies available.

Table 50. Sort Policies
Sort Policy	Sorts By	Default Order	Available for
Temporal	The catalog search result’s effective time field	Newest to oldest	All Search Types
Distance	The catalog search result’s distance field	Nearest to farthest	Point-Radius Spatial searches
Relevance	The catalog search result’s relevance field	Most to least relevant	Contextual

If no sort policy is defined for a particular search, the temporal policy will automatically be applied.

13.1.3.5. Product Retrieval

The DDF is used to catalog resources. A Resource is a URI-addressable entity that is represented by a Metacard. Resources may also be known as products or data. Resources may exist either locally or on a remote data store.

Examples of Resources

NITF image
MPEG video
Live video stream
Audio recording
Document

Product Retrieval Services

SOAP Web services
DDF JSON
DDF REST

The Query Service Endpoint, the Catalog Framework, and the CatalogProvider are key components for processing a retrieve product request. The Endpoint bundle contains a Web service that exposes the interface to retrieve products, also referred to as Resources. The Endpoint calls the CatalogFramework to execute the operations of its specification. The CatalogFramework relies on the Sources to execute the actual product retrieval. Optional PreResource and PostResource Catalog Plugins may be invoked by the CatalogFramework to modify the product retrieval request/response prior to the Catalog Provider processing the request and providing the response. It is possible to retrieve products from specific remote Sources by specifying the site name(s) in the request.

Note	Product Caching Existing DDF clients are able to leverage product caching due to the product cache being implemented in the DDF. Enabling the product cache is an administrator function. Product Caching is enabled by default.

To configure product caching:

Navigate to the Admin Console.
Select Catalog.
Select Configuration.
Select Resource Download Settings.

See Resource Download Settings configurations for all possible configurations.

Product Retrieval Request

13.1.3.6. Notifications and Activities

DDF can send/receive notifications of "Activities" occuring in the system.

13.1.3.6.1. Notifications

Currently, the notifications provide information about product retrieval only.

13.1.3.6.2. Activities

Activity events include the status and progress of actions that are being performed by the user, such as searches and downloads.

13.2. Included Catalog Frameworks, Associated Components, and Configurations

These catalog frameworks are available in a standard DDF installation:

Standard Catalog Framework: Reference implementation of a Catalog Framework that implements all requirements of the Catalog API.
Catalog Framework Camel Component: Supports creating, updating, and deleting metacards using the Catalog Framework from a Camel route.

13.2.1. Standard Catalog Framework

The Standard Catalog Framework provides the reference implementation of a Catalog Framework that implements all requirements of the Catalog API. CatalogFrameworkImpl is the implementation of the DDF Standard Catalog Framework.

The Standard Catalog Framework is the core class of DDF. It provides the methods for create, update, delete, and resource retrieval (CRUD) operations on the Sources. By contrast, the Fanout Catalog Framework only allows for query and resource retrieval operations, no catalog modifications, and all queries are enterprise-wide.

Use this framework if:

access to a catalog provider is required to create, update, and delete catalog entries.
queries to specific sites are required.
queries to only the local provider are required.

It is possible to have only remote Sources configured with no local CatalogProvider configured and be able to execute queries to specific remote sources by specifying the site name(s) in the query request.

The Standard Catalog Framework also maintains a list of ResourceReaders for resource retrieval operations. A resource reader is matched to the scheme (i.e., protocol, such as file://) in the URI of the resource specified in the request to be retrieved.

Site information about the catalog provider and/or any federated source(s) can be retrieved using the Standard Catalog Framework. Site information includes the source’s name, version, availability, and the list of unique content types currently stored in the source (e.g., NITF). If no local catalog provider is configured, the site information returned includes site info for the catalog framework with no content types included.

13.2.1.1. Installing the Standard Catalog Framework

The Standard Catalog Framework is bundled as the catalog-core-standardframework feature and can be installed and uninstalled using the normal processes described in Configuration.

13.2.1.2. Configuring the Standard Catalog Framework

These are the configurable properties on the Standard Catalog Framework.

See Catalog Standard Framework configurations for all possible configurations.

13.2.2.1. Message Headers

13.2.2.1.1. Catalog Framework Producer

Header

Description

operation

the operation to perform using the Catalog Framework (possible values are CREATE | UPDATE | DELETE)

13.2.2.2. Sending Messages to Catalog Framework Endpoint

13.2.2.2.1. Catalog Framework Producer

In Producer mode, the component provides the ability to provide different inputs and have the Catalog framework perform different operations based upon the header values.

For the CREATE and UPDATE operation, the message body can contain a list of metacards or a single metacard object.

For the DELETE operation, the message body can contain a list of strings or a single string object. The string objects represent the IDs of metacards to be deleted. The exchange’s "in" message will be set with the affected metacards. In the case of a CREATE, it will be updated with the created metacards. In the case of the UPDATE, it will be updated with the updated metacards and with the DELETE it will contain the deleted metacards.

Table 53. Catalog Framework Camel Component Operations
Header	Message Body (Input)	Exchange Modification (Output)
operation = CREATE	List<Metacard> or Metacard	exchange.getIn().getBody() updated with List of Metacards created
operation = UPDATE	List<Metacard> or Metacard	exchange.getIn().getBody() updated with List of Metacards updated
operation = DELETE	List<String> or String (representing metacard IDs)	exchange.getIn().getBody() updated with List of Metacards deleted

Note	If there is an exception thrown while the route is being executed, a FrameworkProducerException will be thrown causing the route to fail with a CamelExecutionException.

13.2.2.2.2. Samples

This example demonstrates:

Reading in some sample data from the file system.

14. Transformers

Transformers

Transformers transform data to and from various formats. Transformers are categorized by when they are invoked and used. The existing types are Input transformers, Metacard transformers, and Query Response transformers. Additionally, XSLT transformers are provided to aid in developing custom, lightweight Metacard and Query Response transformers.

Transformers are utility objects used to transform a set of standard DDF components into a desired format, such as into PDF, GeoJSON, XML, or any other format. For instance, a transformer can be used to convert a set of query results into an easy-to-read GeoJSON format (GeoJSON Transformer) or convert a set of results into a RSS feed that can be easily published to a URL for RSS feed subscription. Transformers can be registered in the OSGi Service Registry so that any other developer can access them based on their standard interface and self-assigned identifier, referred to as its "shortname." Transformers are often used by endpoints for data conversion in a system standard way. Multiple endpoints can use the same transformer, a different transformer, or their own published transformer.

Warning

The current transformers only work for UTF-8 characters and do not support Non-Western Characters (for example, Hebrew). It is recommend not to use international character sets, as they may not be displayed properly.

Communication Diagram

Transformers are used to alter the format of a resource or its metadata to or from the catalog’s metacard format.

Types of Transformers

Input Transformers: Input Transformers create metacards from input. Once converted to a Metacard, the data can be used in a variety of ways, such as in an UpdateRequest, CreateResponse, or within Catalog Endpoints or Sources. For instance, an input transformer could be used to receive and translate XML into a Metacard so that it can be placed within a CreateRequest to be ingested within the Catalog. Input transformers should be registered within the Service Registry with the interface ddf.catalog.transform.InputTransformer to notify Catalog components of any new transformers.
Metacard Transformers: Metacard Transformers translate a metacard from catalog metadata to a specific data format.
Query Response Transformers: Query Response transformers convert query responses into other data formats.

14.1. Available Input Transformers

14.4.2. CSW Query Response Transformer

The CSW Query Response Transformer transforms a query response into a CSW-formatted document.

14.4.2.1. Installing the CSW Query Response Transformer

The CSW Query Response Transformer is installed by default with a standard installation in the Spatial application.

14.4.2.2. Configuring the CSW Query Response Transformer

The CSW Query Response Transformer has no configurable properties.

14.4.3. GeoJSON Input Transformer

The GeoJSON input transformer is responsible for translating GeoJSON into a Catalog metacard.

14.4.3.1. Installing the GeoJSON Input Transformer

The GeoJSON Input Transformer is installed by default with a standard installation.

14.4.3.2. Configuring the GeoJSON Input Transformer

The GeoJSON Input Transformer has no configurable properties.

14.4.3.3. Using the GeoJSON Input Transformer

Using the REST Endpoint, for example, HTTP POST a GeoJSON metacard to the Catalog. Once the REST Endpoint receives the GeoJSON Metacard, it is converted to a Catalog metacard.

Example HTTP POST of a Local metacard.json File Using the Curl Command

curl -X POST -i -H "Content-Type: application/json" -d "@metacard.json" https://{FQDN}:{PORT}/services/catalog

14.4.3.4. Conversion to a Metacard

A GeoJSON object consists of a single JSON object. This can be a geometry, a feature, or a FeatureCollection. The GeoJSON input transformer only converts "feature" objects into metacards because feature objects include geometry information and a list of properties. A geometry object alone does not contain enough information to create a metacard. Additionally, the input transformer currently does not handle FeatureCollections.

  { "type": "LineString",
 "coordinates": [ [100.0, 0.0], [101.0, 1.0] ]
 }

The following sample will create a valid metacard:

        "created": "2012-09-01T00:09:19.368+0000",
        "metadata-content-type-version": "myVersion",

            10.0
        ]
    }
}

In the current implementation, Metacard.LOCATION is not taken from the properties list as WKT, but instead interpreted from the geometry JSON object. The geometry object is formatted according to the GeoJSON standard. Dates are in the ISO 8601 standard. White space is ignored, as in most cases with JSON. Binary data is accepted as Base64. XML must be properly escaped, such as what is proper for normal JSON.

Currently, only Required Attributes are recognized in the properties.

14.4.3.4.1. Metacard Extensibility

GeoJSON supports custom, extensible properties on the incoming GeoJSON using DDF’s extensible metacard support. To have those customized attributes understood by the system, a corresponding MetacardType must be registered with the MetacardTypeRegistry. That MetacardType must be specified by name in the metacard-type property of the incoming GeoJSON. If a MetacardType is specified on the GeoJSON input, the customized properties can be processed, cataloged, and indexed.

        "metadata-content-type-version": "myVersion",
        "metadata-content-type": "myType",
        "metadata": "<xml></xml>",

            30.0,
            10.0
        ]
    }
}

When the GeoJSON Input Transformer gets GeoJSON with the MetacardType specified, it will perform a lookup in the MetacardTypeRegistry to obtain the specified MetacardType in order to understand how to parse the GeoJSON. If no MetacardType is specified, the GeoJSON Input Transformer will assume the default MetacardType. If an unregistered MetacardType is specified, an exception will be returned to the client indicating that the MetacardType was not found.

14.4.3.5. Usage Limitations of the GeoJSON Input Transformer

The GeoJSON Input Transformer does not handle multiple geometries.

14.4.4. GeoJSON Metacard Transformer

14.4.8. KML Style Mapper

The KML Style Mapper provides the ability for the KMLTransformer to map a KML Style URL to a metacard based on that metacard’s attributes. For example, if a user wanted all JPEGs to be blue, the KML Style Mapper provides the ability to do so. This would also allow an administrator to configure metacards from each source to be different colors.

The configured style URLs are expected to be HTTP URLs. For more information on style URL’s, refer to the KML Reference .

The KML Style Mapper supports all basic and extended metacard attributes. When a style mapping is configured, the resulting transformed KML contain a <styleUrl> tag pointing to that style, rather than the default KML style supplied by the KMLTransformer.

14.4.8.1. Installing the KML Style Mapper

The KML Style Mapper is installed by default with a standard installation in the Spatial Application in the spatial-kml-transformer feature.

14.4.8.2. Configuring the KML Style Mapper

The properties below describe how to configure a style mapping. The configuration name is Spatial KML Style Map Entry.

See KML Style Mapper configurations for all possible configurations.

14.5. Mime Type Mapper

The MimeTypeMapper is the entry point in DDF for resolving file extensions to mime types, and vice versa.

MimeTypeMappers are used by the ResourceReader to determine the file extension for a given mime type in aid of retrieving a product. MimeTypeMappers are also used by the FileSystemProvider in the Catalog Framework to read a file from the content file repository.

The MimeTypeMapper maintains a list of all of the MimeTypeResolvers in DDF.

The MimeTypeMapper accesses each MimeTypeResolver according to its priority until the provided file extension is successfully mapped to its corresponding mime type. If no mapping is found for the file extension, null is returned for the mime type. Similarly, the MimeTypeMapper accesses each MimeTypeResolver according to its priority until the provided mime type is successfully mapped to its corresponding file extension. If no mapping is found for the mime type, null is returned for the file extension.

For files with no file extension, the MimeTypeMapper will attempt to determine the mime type from the contents of the file. If it is unsuccessful, the file will be ingested as a binary file.

DDF Mime Type Mapper: Core implementation of the DDF Mime API.

14.5.1. DDF Mime Type Mapper

The DDF Mime Type Mapper is the core implementation of the DDF Mime API. It provides access to all MimeTypeResolvers within DDF, which provide mapping of mime types to file extensions and file extensions to mime types.

14.5.1.1. Installing the DDF Mime Type Mapper

The DDF Mime Type Mapper is installed by default with a standard installation in the Platform application.

14.5.1.2. Configuring DDF Mime Type Mapper

The DDF Mime Type Mapper has no configurable properties.

14.6. Mime Type Resolver

A MimeTypeResolver is a DDF service that can map a file extension to its corresponding mime type and, conversely, can map a mime type to its file extension.

MimeTypeResolvers are assigned a priority (0-100, with the higher the number indicating the higher priority). This priority is used to sort all of the MimeTypeResolvers in the order they should be checked to map a file extension to a mime type (or vice versa). This priority also allows custom MimeTypeResolvers to be invoked before default MimeTypeResolvers by setting custom resolver’s priority higher than the default.

MimeTypeResolvers are not typically invoked directly. Rather, the MimeTypeMapper maintains a list of MimeTypeResolvers (sorted by their priority) that it invokes to resolve a mime type to its file extension (or to resolve a file extension to its mime type).

Custom Mime Type Resolver: The Custom Mime Type Resolver is a MimeTypeResolver that defines the custom mime types that DDF will support.
Tika Mime Type Resolver: Provides support for resolving over 1300 mime types.

14.6.1. Custom Mime Type Resolver

These are mime types not supported by the default TikaMimeTypeResolver.

Table 62. Custom Mime Type Resolver Default Supported Mime Types
File Extension	Mime Type
`nitf`	`image/nitf`
`ntf`	`image/nitf`
`json`	`json=application/json;id=geojson`

As a MimeTypeResolver, the Custom Mime Type Resolver will provide methods to map the file extension to the corresponding mime type, and vice versa.

14.6.1.1. Installing the Custom Mime Type Resolver

One Custom Mime Type Resolver is configured and installed for the image/nitf mime type. This custom resolver is bundled in the mime-core-app application and is part of the mime-core feature.

Additional Custom Mime Type Resolvers can be added for other custom mime types.

14.6.1.1.1. Configuring the Custom Mime Type Resolver

The configurable properties for the Custom Mime Type Resolver are accessed from the MIME Custom Types configuration in the Admin Console.

Navigate to the Admin Console.
Select the Platform application.
Select Configuration.
Select MIME Custom Types.

Managed Service Factory PID

Ddf_Custom_Mime_Type_Resolver

See Custom Mime Type Resolver configurations for all possible configurations.

14.6.2. Tika Mime Type Resolver

The TikaMimeTypeResolver is a MimeTypeResolver that is implemented using the Apache Tika open source product.

Using the Apache Tika content analysis toolkit, the TikaMimeTypeResolver provides support for resolving over 1300 mime types, but not all mime types yield the same quality metadata.

The TikaMimeTypeResolver is assigned a default priority of -1 to insure that it is always invoked last by the MimeTypeMapper. This insures that any custom MimeTypeResolvers that may be installed will be invoked before the TikaMimeTypeResolver.

The TikaMimeTypeResolver provides the bulk of the default mime type support for DDF.

14.6.2.1. Installing the Tika Mime Type Resolver

The TikaMimeTypeResolver is bundled as the mime-tika-resolver feature in the mime-tika-app application.

This feature is installed by default.

14.6.2.1.1. Configuring the Tika Mime Type Resolver

The Tika Mime Type Resolver has no configurable properties.

15. Catalog Plugins

15.2.7. Event Processor

The Event Processor creates, updates, and deletes subscriptions for event notification. These subscriptions optionally specify a filter criteria so that only events of interest to the subscriber are posted for notification.

As metacards are created, updated, and deleted, the Catalog’s Event Processor is invoked (as a post-ingest plugin) for each of these events. The Event Processor applies the filter criteria for each registered subscription to each of these ingest events to determine if they match the criteria.

For more information on creating subscriptions, see Creating a Subscription.

15.2.7.1. Installing the Event Processor

15.2.9. Filter Plugin

The Filter Plugin performs filtering on query responses as they pass through the framework.

Each metacard result can contain security attributes that are pulled from the metadata record after being processed by a PolicyPlugin that populates this attribute. The security attribute is a Map containing a set of keys that map to lists of values. The metacard is then processed by a filter plugin that creates a KeyValueCollectionPermission from the metacard’s security attribute. This permission is then checked against the user subject to determine if the subject has the correct claims to view that metacard. The decision to filter the metacard eventually relies on the installed Policy Decision Point (PDP). The PDP that is being used returns a decision, and the metacard will either be filtered or allowed to pass through.

How a metacard gets filtered is left up to any number of FilterStrategy implementations that might be installed. Each FilterStrategy will return a result to the filter plugin that says whether or not it was able to process the metacard, along with the metacard or response itself. This allows a metacard or entire response to be partially filtered to allow some data to pass back to the requester. This could also include filtering any products sent back to a requester.

The security attributes populated on the metacard are completely dependent on the type of the metacard. Each type of metacard must have its own PolicyPlugin that reads the metadata being returned and then returns the appropriate attributes.

Example (represented as simple XML for ease of understanding):

  <metacard>
    <security>
        <map>
            <entry assertedAttribute1="A,B" />
            <entry assertedAttribute2="X,Y" />
            <entry assertedAttribute3="USA,GBR" />
            <entry assertedAttribute4="USA,AUS" />
        </map>
    </security>
</metacard>

  <user>
    <claim name="subjectAttribute1">
        <value>A</value>
        <value>B</value>
    </claim>
    <claim name="subjectAttribute2">
        <value>X</value>
        <value>Y</value>
    </claim>
    <claim name="subjectAttribute3">
        <value>USA</value>
    </claim>
    <claim name="subjectAttribute4">
        <value>USA</value>
    </claim>
</user>

In the above example, the user’s claims are represented very simply and are similar to how they would actually appear in a SAML 2 assertion. Each of these user (or subject) claims will be converted to a KeyValuePermission object. These permission objects will be implied against the permission object generated from the metacard record. In this particular case, the metacard might be allowed if the policy is configured appropriately because all of the permissions line up correctly.

15.2.9.1. Installing the Filter Plugin

The Filter Plugin is installed by default with a standard installation in the Catalog application.

15.2.9.2. Configuring the Filter Plugin

The Filter Plugin has no configurable properties.

15.2.10. GeoCoder Plugin

If there is a valid country code for the Metacard, it will be in ISO 3166-1 alpha-3 format. If the metacard’s country code is already populated, the plugin will not override it. The GeoCoder relies on either the WebService or Offline Gazetteer to retrieve country code information.

Warning

For a polygon or polygons, this plugin takes the center point of the bounding box to assign the country code.

15.2.10.1. Installing the GeoCoder Plugin

15.2.14. Metacard Attribute Security Policy Plugin

The Metacard Attribute Security Policy Plugin combines existing metacard attributes to make new attributes and adds them to the metacard. For example, if a metacard has two attributes, sourceattribute1 and sourceattribute2, the values of the two attributes could be combined into a new attribute, destinationattribute1. The sourceattribute1 and sourceattribute2 are the source attributes and destinationattribute1 is the destination attribute.

There are two way to combine the values of source attributes. The first, and most common, is to take all of the attribute values and put them together. This is called the union. For example, if the source attributes sourceattribute1 and sourceattribute2 had the values:

sourceattribute1 = MASK, VESSEL

sourceattribute2 = WIRE, SACK, MASK

…the union would result in the new attribute destinationattribute1:

destinationattribute1 = MASK, VESSEL, WIRE, SACK

The other way to combine attributes is use the values common to all of the attributes. This is called the intersection. Using our previous example, the intersection of sourceattribute1 and sourceattribute2 would create the new attribute destinationattribute1

destinationattribute1 = MASK

because only MASK is common to all of the source attributes.

The policy plugin could also be used to rename attributes. If there is only one source attribute, and the combination policy is union, then the attribute’s values are effectively renamed to the destination attribute.

15.2.14.1. Installing the Metacard Attribute Security Policy Plugin

The Metacard Attribute Security Policy Plugin is installed by default with a standard installation in the Catalog application.

Overwrites the Metacard.ID field with a generated, unique, 32 character hexadecimal value if missing or if the resource URI is not a catalog resource URI.
Sets Metacard.CREATED to the current time stamp if not already set.
Sets Metacard.MODIFIED to the current time stamp if not already set.
Sets Core.METACARD_CREATED to the current time stamp if not present.
Sets Core.METACARD_MODIFIED to the current time stamp.

In an UpdateRequest, the same operations are performed as a CreateRequest, except:

If no value is provided for Metacard.ID in the new metacard, it will be set using the UpdateRequest ID if applicable.

15.2.17.1. Installing the Metacard Groomer

15.2.18. Metacard Ingest Network Plugin

The Metacard Ingest Network Plugin allows the conditional insertion of new attributes on metacards during ingest based on network information from the ingest request; including IP address and hostname.

For the extent of this section, a 'rule' will refer to a configured, single instance of this plugin.

15.2.18.1. Related Components to the Metacard Ingest Network Plugin

Client Info Plugin

15.2.18.2. Installing the Metacard Ingest Network Plugin

The Metacard Ingest Network Plugin is installed by default during a standard installation in the Catalog application.

15.2.18.3. Configuring the Metacard Ingest Network Plugin

To configure the Metacard Ingest Network Plugin:

Navigate to the Admin Console.
Select the Catalog application.
Select the Configuration tab.
Select the label Metacard Ingest Network Plugin to setup a network rule.

See Metacard Ingest Network Plugin configurations for all possible configurations.

Multiple instances of the plugin can be configured by clicking on its configuration title within the configuration tab of the Catalog app. Each instance represents a conditional statement, or a 'rule', that gets evaluated for each ingest request. For any request that meets the configured criteria of a rule, that rule will attempt to transform its list of key-value pairs to become new attributes on all metacards in that request.

The rule is divided into two fields: "Criteria" and "Expected Value". The "Criteria" field features a drop-down list containing the four elements for which equality can be tested:

IP Address of where the ingest request came from
Host Name of where the ingest request came from
Scheme that the ingest request arrived on, for example, http vs https
Context Path that the ingest request arrived on, for example, /services/catalog

In order for a rule to evaluate to true and the attributes be applied, the value in the "Expected Value" field must be an exact match to the actual value of the selected criteria. For example, if the selected criteria is "IP Address" with an expected value of "192.168.0.1", the rule only evaluates to true for ingest requests coming from "192.168.0.1" and nowhere else.

Important

Check for IPv6

Verify your system’s IP configuration. Rules using "IP Address" may need to be written in IPv6 format.

The key-value pairs within each rule should take the following form: "key = value" where the "key" is the name of the attribute and the "value" is the value assigned to that attribute. Whitespace is ignored unless it is within the key or value. Multi-valued attributes can be expressed in comma-separated format if necessary.

Examples of Valid Attribute Assignments

contact.contributor-name = John Doe
contact.contributor-email = john.doe@example.net
language = English
language = English, French, German
security.access-groups = SJ202, SR 101, JS2201

15.2.18.3.1. Useful Attributes

The following table provides some useful attributes that may commonly be set by this plugin:

Table 65. Useful Attributes
Attribute Name	Expected Format	Multi-Valued
expiration	ISO DateTime	no
description	Any String	no
metacard.owner	Any String	no
language	Any String	yes
security.access-groups	Any String	yes
security.access-individuals	Any String	yes

15.2.18.4. Usage Limitations of the Metacard Ingest Network Plugin

This plugin only works for ingest (create requests) performed over a network; data ingested via command line does not get processed by this plugin.
Any attribute that is already set on the metacard will not be overwritten by the plugin.
The order of execution is not guaranteed. For any rule configuration where two or more rules add different values for the same attribute, it is undefined what the final value for that attribute will be in the case where more than one of those rules evaluates to true.

15.2.19. Metacard Resource Size Plugin

This post-query plugin updates the resource size attribute of each metacard in the query results if there is a cached file for the product and it has a size greater than zero; otherwise, the resource size is unmodified and the original result is returned.

16. Data

Catalog Architecture Diagram: Data

The Catalog stores and translates Metadata, which can be transformed into many data formats, shared, and queried. The primary form of this metadata is the metacard. A Metacard is a container for metadata. CatalogProviders accept Metacards as input for ingest, and Sources search for metadata and return matching Results that include Metacards.

16.1. Metacards

A metacard is a single instance of metadata in the Catalog (an instance of a metacard type) which generally contains general information about the product, such as the title of the product, the product’s geo-location, the date the product was created and/or modified, the owner or producer, and/or the security classification.

16.1.1. Metacard Type

A metacard type indicates the attributes available for a particular metacard. It is a model used to define the attributes of a metacard, much like a schema.

A metacard type indicates the attributes available for a particular type of data. For example, an image may have different attributes than a PDF document, so each could be defined to have their own metacard type.

16.1.1.1. Default Metacard Type and Attributes

Most metacards within the system are created using the default metacard type or a metacard type based on the default type. The default metacard type of the system can be programmatically retrieved by calling ddf.catalog.data.impl.MetacardImpl.BASIC_METACARD. The name of the default MetacardType can be retrieved from ddf.catalog.data.MetacardType.DEFAULT_METACARD_TYPE_NAME.

The default metacard type has the following required attributes. Though the following attributes are required on all metacard types, setting their values is optional except for ID.

Core Attributes

Note

It is highly recommended when referencing a default attribute name to use the ddf.catalog.data.types.* interface constants whenever possible. Mapping to a normalized taxonomy allows for higher quality transformations between different formats and for improved federation. This neutral profile facilitates improved search and discovery across disparate data types.

Warning

Every Source should at the very least return an ID attribute according to Catalog API. Other fields may or may not be applicable, but a unique ID must be returned by a source.

16.1.1.2. Extensible Metacards

Metacard extensibility is achieved by creating a new MetacardType that supports attributes in addition to the required attributes listed above.

Required attributes must be the base of all extensible metacard types.

Warning

Not all Catalog Providers support extensible metacards. Nevertheless, each Catalog Provider should at least have support for the default MetacardType; i.e., it should be able to store and query on the attributes and attribute formats specified by the default metacard type. Catalog providers are neither expected nor required to store attributes that are not in a given metacard’s type.

Consult the documentation of the Catalog Provider in use for more information on its support of extensible metacards.

Often, the BASIC_METACARD MetacardType does not provide all the functionality or attributes necessary for a specific task. For performance or convenience purposes, it may be necessary to create custom attributes even if others will not be aware of those attributes. One example could be if a user wanted to optimize a search for a date field that did not fit the definition of CREATED, MODIFIED, EXPIRATION, or EFFECTIVE. The user could create an additional java.util.Date attribute in order to query the attribute separately.

Metacard objects are extensible because they allow clients to store and retrieve standard and custom key/value Attributes from the Metacard. All Metacards must return a MetacardType object that includes an AttributeDescriptor for each Attribute, indicating it’s key and value type. AttributeType support is limited to those types defined by the Catalog.

New MetacardType implementations can be made by implementing the MetacardType interface.

16.1.2. Metacard Type Registry

Warning

The MetacardTypeRegistry is experimental. While this component has been tested and is functional, it may change as more information is gathered about what is needed and as it is used in more scenarios.

The MetacardTypeRegistry allows DDF components, primarily catalog providers and sources, to make available the MetacardTypes that they support. It maintains a list of all supported MetacardTypes in the CatalogFramework, so that other components such as Endpoints, Plugins, and Transformers can make use of those MetacardTypes. The MetacardType is essential for a component in the CatalogFramework to understand how it should interpret a metacard by knowing what attributes are available in that metacard.

For example, an endpoint receiving incoming metadata can perform a lookup in the MetacardTypeRegistry to find a corresponding MetacardType. The discovered MetacardType will then be used to help the endpoint populate a metacard based on the specified attributes in the MetacardType. By doing this, all the incoming metadata elements can then be available for processing, cataloging, and searching by the rest of the CatalogFramework.

MetacardTypes should be registered with the MetacardTypeRegistry. The MetacardTypeRegistry makes those MetacardTypes available to other DDF CatalogFramework components. Other components that need to know how to interpret metadata or metacards should look up the appropriate MetacardType from the registry. By having these MetacardTypes available to the CatalogFramework, these components can be aware of the custom attributes.

The MetacardTypeRegistry is accessible as an OSGi service. The following blueprint snippet shows how to inject that service into another component:

MetacardTypeRegistry Service Injection

  <bean id="sampleComponent" class="ddf.catalog.SampleComponent">
    <argument ref="metacardTypeRegistry" />
</bean>

<!-- Access MetacardTypeRegistry -->
<reference id="metacardTypeRegistry" interface="ddf.catalog.data.MetacardTypeRegistry"/>

The reference to this service can then be used to register new MetacardTypes or to lookup existing ones.

Typically, new MetacardTypes will be registered by CatalogProviders or sources indicating they know how to persist, index, and query attributes from that type. Typically, Endpoints or InputTransformers will use the lookup functionality to access a MetacardType based on a parameter in the incoming metadata. Once the appropriate MetacardType is discovered and obtained from the registry, the component will know how to translate incoming raw metadata into a DDF Metacard.

16.1.3. Attributes

An attribute is a single field of a metacard, an instance of an attribute type. Attributes are typically indexed for searching by a source or catalog provider.

16.1.3.1. Attribute Types

An attribute type indicates the attribute format of the value stored as an attribute. It is a model for an attribute.

16.1.3.1.1. Attribute Format

An enumeration of attribute formats are available in the catalog. Only these attribute formats may be used.

Table 66. Attribute Formats
AttributeFormat	Description
`BINARY`	Attributes of this attribute format must have a value that is a Java `byte[]` and `AttributeType.getBinding()` should return `Class<Array>of` byte.
`BOOLEAN`	Attributes of this attribute format must have a value that is a Java boolean.
`DATE`	Attributes of this attribute format must have a value that is a Java date.
`DOUBLE`	Attributes of this attribute format must have a value that is a Java double.
`FLOAT`	Attributes of this attribute format must have a value that is a Java float.
`GEOMETRY`	Attributes of this attribute format must have a value that is a WKT-formatted Java string.
`INTEGER`	Attributes of this attribute format must have a value that is a Java integer.
`LONG`	Attributes of this attribute format must have a value that is a Java long.
`OBJECT`	Attributes of this attribute format must have a value that implements the serializable interface.
`SHORT`	Attributes of this attribute format must have a value that is a Java short.
`STRING`	Attributes of this attribute format must have a value that is a Java string and treated as plain text.
`XML`	Attributes of this attribute format must have a value that is a XML-formatted Java string.

16.1.3.1.2. Attribute Naming Conventions

Catalog taxonomy elements follow the naming convention of group-or-namespace.specific-term, except for extension fields outside of the core taxonomy. These follow the naming convention of ext.group-or-namespace.specific-term and must be namespaced. Nesting is not permitted.

16.1.3.2. Result

A single "hit" included in a query response.

A result object consists of the following:

a metacard.
a relevance score if included.
distance in meters if included.

16.1.4. Creating Metacards

The quickest way to create a Metacard is to extend or construct the MetacardImpl object. MetacardImpl is the most commonly used and extended Metacard implementation in the system because it provides a convenient way for developers to retrieve and set Attributes without having to create a new MetacardType (see below). MetacardImpl uses BASIC_METACARD as its MetacardType.

16.1.4.1. Limitations

A given developer does not have all the information necessary to programmatically interact with any arbitrary source. Developers hoping to query custom fields from extensible Metacards of other sources cannot easily accomplish that task with the current API. A developer cannot question a source for all its queryable fields. A developer only knows about the MetacardTypes which that individual developer has used or created previously.

The only exception to this limitation is the Metacard.ID field, which is required in every Metacard that is stored in a source. A developer can always request Metacards from a source for which that developer has the Metacard.ID value. The developer could also perform a wildcard search on the Metacard.ID field if the source allows.

16.1.4.2. Processing Metacards

As Metacard objects are created, updated, and read throughout the Catalog, care should be taken by all catalog components to interrogate the MetacardType to ensure that additional Attributes are processed accordingly.

16.1.4.3. Basic Types

The Catalog includes definitions of several basic types all found in the ddf.catalog.data.BasicTypes class.

Table 67. Basic Types
Name	Type	Description
`BASIC_METACARD`	MetacardType	Represents all required Metacard Attributes.
`BINARY_TYPE`	AttributeType	A Constant for an `AttributeType` with `AttributeType.AttributeFormat.BINARY`.
`BOOLEAN_TYPE`	AttributeType	A Constant for an `AttributeType` with `AttributeType.AttributeFormat.BOOLEAN`.
`DATE_TYPE`	AttributeType	A Constant for an `AttributeType` with `AttributeType.AttributeFormat.DATE`.
`DOUBLE_TYPE`	AttributeType	A Constant for an `AttributeType` with `AttributeType.AttributeFormat.DOUBLE`.
`FLOAT_TYPE`	AttributeType	A Constant for an `AttributeType` with `AttributeType.AttributeFormat.FLOAT`.
`GEO_TYPE`	AttributeType	A Constant for an `AttributeType` with `AttributeType.AttributeFormat.GEOMETRY`.
`INTEGER_TYPE`	AttributeType	A Constant for an `AttributeType` with `AttributeType.AttributeFormat.INTEGER`.
`LONG_TYPE`	AttributeType	A Constant for an `AttributeType` with `AttributeType.AttributeFormat.LONG`.
`OBJECT_TYPE`	AttributeType	A Constant for an `AttributeType` with `AttributeType.AttributeFormat.OBJECT`.
`SHORT_TYPE`	AttributeType	A Constant for an `AttributeType` with `AttributeType.AttributeFormat.SHORT`.
`STRING_TYPE`	AttributeType	A Constant for an `AttributeType` with `AttributeType.AttributeFormat.STRING`.
`XML_TYPE`	AttributeType	A Constant for an `AttributeType` with `AttributeType.AttributeFormat.XML`.

17. Operations

The Catalog provides the capability to query, create, update, and delete metacards; retrieve resources; and retrieve information about the sources in the enterprise.

Each of these operations follow a request/response paradigm. The request is the input to the operation and contains all of the input parameters needed by the Catalog Framework’s operation to communicate with the Sources. The response is the output from the execution of the operation that is returned to the client, which contains all of the data returned by the sources. For each operation there is an associated request/response pair, e.g., the QueryRequest and QueryResponse pair for the Catalog Framework’s query operation.

All of the request and response objects are extensible in that they can contain additional key/value properties on each request/response. This allows additional capability to be added without changing the Catalog API, helping to maintain backwards compatibility.

18. Resources

Resources Architecture

Resources are the data that is represented by the cataloged metadata in DDF.

Metacards are used to describe those resources through metadata. This metadata includes the time the resource was created, the location where the resource was created, etc. A DDF Metacard contains the getResourceUri method, which is used to locate and retrieve its corresponding resource.

Content Data Component Architecture

18.1. Content Item

ContentItem is the domain object populated by the Storage Provider that represents the information about the content to be stored or content that has been stored in the Storage Provider. A ContentItem encapsulates the content’s globally unique ID, mime type, and input stream (i.e., the actual content). The unique ID of a ContentItem will always correspond to a Metacard ID.

18.1.1. Retrieving Resources

When a client attempts to retrieve a resource, it must provide a metacard ID or URI corresponding to a unique resource. As mentioned above, the resource URI is obtained from a Metacard’s `getResourceUri method. The CatalogFramework has three methods that can be used by clients to obtain a resource: getEnterpriseResource, getResource, and getLocalResource. The getEnterpriseResource method invokes the retrieveResource method on a local ResourceReader as well as all the Federated and Connected Sources inthe DDF enterprise. The second method, getResource, takes in a source ID as a parameter and only invokes retrieveResource on the specified Source. The third method invokes retrieveResource on a local ResourceReader.

The parameter for each of these methods in the CatalogFramework is a ResourceRequest. DDF includes two implementations of ResourceRequest: ResourceRequestById and ResourceRequestByProductUri. Since these implementations extend OperationImpl, they can pass a Map of generic properties through the CatalogFramework to customize how the resource request is carried out. One example of this is explained in the Retrieving Resource Options section below. The following is a basic example of how to create a ResourceRequest and invoke the CatalogFramework resource retrieval methods to process the request.

Retrieve Resource Example


  1

  Map<String, Serializable> properties = new HashMap<String, Serializable>();
properties.put("PropertyKey1", "propertyA"); //properties to customize Resource retrieval
ResourceRequestById resourceRequest = new ResourceRequestById("0123456789abcdef0123456789abcdef", properties); //object containing ID of Resource to be retrieved
String sourceName = "LOCAL_SOURCE"; //the Source ID or name of the local Catalog or a Federated Source
ResourceResponse resourceResponse; //object containing the retrieved Resource and the request that was made to get it.
resourceResponse = catalogFramework.getResource(resourceRequest, sourceName); //Source-based retrieve Resource request
Resource resource = resourceResponse.getResource(); //actual Resource object containing InputStream, mime type, and Resource name

DDF.catalog.resource.ResourceReader instances can be discovered via the OSGi Service Registry. The system can contain multiple ResourceReaders. The CatalogFramework determines which one to call based on the scheme of the resource’s URI and what schemes the ResourceReader supports. The supported schemes are obtained by a ResourceReader’s `getSupportedSchemes method. As an example, one ResourceReader may know how to handle file-based URIs with the scheme file, whereas another ResourceReader may support HTTP-based URIs with the scheme http.

The ResourceReader or Source is responsible for locating the resource, reading its bytes, adding the binary data to a Resource implementation, then returning that Resource in a ResourceResponse. The ResourceReader or Source is also responsible for determining the Resource’s name and mime type, which it sends back in the `Resource implementation.

18.1.1.1. BinaryContent

BinaryContent is an object used as a container to store translated or transformed DDF components. Resource extends BinaryContent and includes a getName method. ` BinaryContent` has methods to get the InputStream, byte array, MIME type, and size of the represented binary data. An implementation of BinaryContent (BinaryContentImpl) can be found in the Catalog API in the DDF.catalog.data package.

18.1.2. Retrieving Resource Options

Options can be specified on a retrieve resource request made through any of the supporting endpoint. To specify an option for a retrieve resource request, the endpoint needs to first instantiate a ResourceRequestByProductUri or a ResourceRequestById. Both of these ResourceRequest implementations allow a Map of properties to be specified. Put the specified option into the Map under the key RESOURCE_OPTION.

Retrieve Resource with Options


  1

3

  Map<String, Serializable> properties = new HashMap<String, Serializable>();
properties.put("RESOURCE_OPTION", "OptionA");
ResourceRequestById resourceRequest = new ResourceRequestById("0123456789abcdef0123456789abcdef", properties);

Depending on the support that the ResourceReader or Source provides for options, the properties``Map will be checked for the RESOURCE_OPTION entry. If that entry is found, the option will be handled. If the ResourceReader or Source does not support options, that entry will be ignored.

A new ResourceReader or Source implementation can be created to support options in a way that is most appropriate. Since the option is passed through the catalog framework as a property, the ResourceReader or Source will have access to that option as long as the endpoint supports options.

18.1.3. Storing Resources

Resources are saved using a ResourceWriter. DDF.catalog.resource.ResourceWriter instances can be discovered via the OSGi Service Registry. Once retrieved, the ResourceWriter instance provides clients with a way to store resources and get a corresponding URI that can be used to subsequently retrieve the resource via a ResourceReader. Simply invoke either of the storeResource methods with a resource and any potential arguments. The ResourceWriter implementation is responsible for determining where the resource is saved and how it is saved. This allows flexibility for a resource to be saved in any one of a variety of data stores or file systems. The following is an example of how to use a generic implementation of ResourceWriter.

Using a ResourceWriter

  InputStream inputStream = <Video_Input_Stream>; //InputStream of raw Resource data
MimeType mimeType = new MimeType("video/mpeg"); //Mime Type or content type of Resource
String name = "Facility_Video";  //Descriptive Resource name
Resource resource = new ResourceImpl(inputStream, mimeType, name);
Map<String, Object> optionalArguments = new HashMap<String, Object>();
ResourceWriter writer = new ResourceWriterImpl();
URI resourceUri; //URI that can be used to retrieve Resource
resourceUri = writer.storeResource(resource, optionalArguments); //Null can be passed in here

18.2. Resource Components

Resource components are used when working with resources

A resource is a URI-addressable entity that is represented by a metacard. Resources may also be known as products or data.

Resources may exist either locally or on a remote data store.

Examples of resources include:

NITF image
MPEG video
Live video stream
Audio recording
Document

A resource object in DDF contains an InputStream with the binary data of the resource. It describes that resource with a name, which could be a file name, URI, or another identifier. It also contains a mime type or content type that a client can use to interpret the binary data.

18.3. Resource Readers

A resource reader retrieves resources associated with metacards via URIs. Each resource reader must know how to interpret the resource’s URI and how to interact with the data store to retrieve the resource.

There can be multiple resource readers in a Catalog instance. The Catalog Framework selects the appropriate resource reader based on the scheme of the resource’s URI.

In order to make a resource reader available to the Catalog Framework, it must be exported to the OSGi Service Registry as a DDF.catalog.resource.ResourceReader.

18.3.1. URL Resource Reader

The URLResourceReader is an implementation of ResourceReader which is included in the DDF Catalog. It obtains a resource given an http, https, or file-based URL. The URLResourceReader will connect to the provided Resource URL and read the resource’s bytes into an InputStream.

Warning

When a resource linked using a file-based URL is in the product cache, the URLResourceReader’s rootResourceDirectories is not checked when downloading the product. It is downloaded from the product cache which bypasses the URLResourceReader. For example, if path /my/valid/path is configured in the URLResourceReader’s rootResourceDirectories and one downloads the product with resource-uri file:///my/valid/path/product.txt and then one removes /my/valid/path from the URLResourceReader’s rootResourceDirectories configuration, the product will still be accessible via the product cache.

18.3.1.1. Installing the URL Resource Reader

The URLResourceReader is installed by default with a standard installation in the Catalog application.

18.3.1.2. Configuring Permissions for the URL Resource Reader

Configuring the URL Resource Reader to retrieve files requires adding Security Manager read permission entries for the directory containing the resources. To add the correct permission entries, edit the file <DDF_HOME>/security/configurations.policy. In the URL Resource Reader section of the file, add two new permission for each top-level directory that the Resource Reader needs to access. The Resource Reader needs one permission to read the directory and another to read its contents.

Warning

Adding New Permissions

After adding permission entries, a system restart is required for them to take effect.

grant codeBase "file:/org.apache.tika.core/catalog-core-urlresourcereader" { permission java.io.FilePermission "<DIRECTORY_PATH>", "read"; permission java.io.FilePermission "<OTHER_DIRECTORY_PATH>", "read"; }

18.3.1.3. Configuring the URL Resource Reader

Configure the URL Resource Reader from the Admin Console.

Navigate to the Admin Console.
Select the Catalog application.
Select the Configuration tab.
Select the URL Resource Reader.

See URL Resource Reader configurations for all possible configurations.

18.3.2. Using the URL Resource Reader

URLResourceReader will be used by the Catalog Framework to obtain a resource whose metacard is cataloged in the local data store. This particular ResourceReader will be chosen by the CatalogFramework if the requested resource’s URL has a protocol of http, https, or file.

For example, requesting a resource with the following URL will make the Catalog Framework invoke the URLResourceReader to retrieve the product.

Example

file:///home/users/DDF_user/data/example.txt

If a resource was requested with the URL udp://123.45.67.89:80/SampleResourceStream, the URLResourceReader would not be invoked.

Supported Schemes:

http
https
file

Note	If a file-based URL is passed to the `URLResourceReader`, that file path needs to be accessible by the DDF instance.

18.4. Resource Writers

A resource writer stores a resource and produces a URI that can be used to retrieve the resource at a later time. The resource URI uniquely locates and identifies the resource. Resource writers can interact with an underlying data store and store the resource in the proper place. Each implementation can do this differently, providing flexibility in the data stores used to persist the resources.

Resource Writers should be used within the Content Framework if and when implementing a custom Storage Provider to store the product. The default Storage Provider that comes with the DDF writes the products to the file system.

19. Queries

Clients use ddf.catalog.operation.Query objects to describe which metacards are needed from Sources.

Query objects have two major components:

Filters
Query Options

A Source uses the Filter criteria constraints to find the requested set of metacards within its domain of metacards. The Query Options are used to further restrict the Filter’s set of requested metacards.

19.1. Filters

An OGC Filter is a Open Geospatial Consortium (OGC) standard that describes a query expression in terms of Extensible Markup Language (XML) and key-value pairs (KVP). The OGC Filter is used to represent a query to be sent to sources and the Catalog Provider, as well as to represent a Subscription. The OGC Filter provides support for expression processing, such as adding or dividing expressions in a query, but that is not the intended use for DDF.

The Catalog Framework does not use the XML representation of the OGC Filter standard. DDF instead uses the Java implementation provided by GeoTools . GeoTools provides Java equivalent classes for OGC Filter XML elements. GeoTools originally provided the standard Java classes for the OGC Filter Encoding 1.0 under the package name org.opengis.filter. The same package name is used today and is currently used by DDF. Java developers do not parse or view the XML representation of a Filter in DDF. Instead, developers use only the Java objects to complete query tasks.

Note that the ddf.catalog.operation.Query interface extends the org.opengis.filter.Filter interface, which means that a Query object is an OGC Java Filter with Query Options.

A Query is an OGC Filter

public interface Query extends Filter

19.1.1. FilterBuilder API

To avoid the complexities of working with the Filter interface directly and implementing the DDF Profile of the Filter specification, the Catalog includes an API, primarily in DDF.filter, to build Filters using a fluent API.

To use the FilterBuilder API, an instance of DDF.filter.FilterBuilder should be used via the OSGi registry. Typically, this will be injected via a dependency injection framework. Once an instance of FilterBuilder is available, methods can be called to create and combine Filters.

Tip	The fluent API is best accessed using an IDE that supports code-completion. For additional details, refer to the [Catalog API Javadoc].

19.1.2. Boolean Operators

Filters use a number of boolean operators.

FilterBuilder.allOf(Filter …): creates a new Filter that requires all provided Filters are satisfied (Boolean AND), either from a List or Array of Filter instances.
FilterBuilder.anyOf(Filter …): creates a new Filter that requires at least one of the provided Filters are satisfied (Boolean OR), either from a List or Array of Filter instances.
FilterBuilder.not(Filter filter): creates a new Filter that requires the provided Filter must not match (Boolean NOT).

19.1.3. Attribute

Filters can be based on specific attributes.

FilterBuilder.attribute(String attributeName):: begins a fluent API for creating an Attribute-based Filter, i.e., a Filter that matches on Metacards with Attributes of a particular value.

19.1.4. XPath

Filters can be based on XML attributes.

FilterBuilder.xpath(String xpath):: begins a fluent API for creating an XPath-based Filter, i.e., a Filter that matches on Metacards with Attributes of type XML that match when evaluating a provided XPath selector.

Contextual Operators

  FilterBuilder.attribute(attributeName).is().like().text(String contextualSearchPhrase);
FilterBuilder.attribute(attributeName).is().like().caseSensitiveText(StringcaseSensitiveContextualSearchPhrase);
FilterBuilder.attribute(attributeName).is().like().fuzzyText(String fuzzySearchPhrase);

20. Metrics

DDF includes a system of data-collection to enable monitoring system health, user interactions, and overall system performance: Metrics Collection.

The Metrics Collection Application collects data for all of the pre-configured metrics in DDF and stores them in custom JMX Management Bean (MBean) attributes. Samples of each metric’s data is collected every 60 seconds and stored in the <DDF_HOME>/data/metrics directory with each metric stored in its own .rrd file. Refer to the Metrics Reporting Application for how the stored metrics data can be viewed.

Warning

Do not remove the <DDF_HOME>/data/metrics directory or any files in it. If this is done, all existing metrics data will be permanently lost.

Also note that if DDF is uninstalled/re-installed that all existing metrics data will be permanently lost.

Types of Metrics Collected

Catalog Metrics: Metrics collected about the catalog status.
Source Metrics: Metrics collected per source.

20.1. Metrics Collection Application

The Metrics Collection Application is responsible for collecting both Catalog and Source metrics.

Use Metrics Collection to collect historical metrics data, such as catalog query metrics, message latency, or individual sources' metrics type of data.

20.1.1. Installing Metrics Collection

The Metrics Collection application is installed by default with a standard installation.

The catalog-level metrics are packaged as the catalog-core-metricsplugin feature, and the source-level metrics are packaged as the catalog-core-sourcemetricsplugin feature.

20.1.2. Configuring Metrics Collection

No configuration is made for the Metrics Collection application. All metrics collected are either pre-configured in DDF or dynamically created as sources are created or deleted.

20.1.3. Catalog Metrics

Table 68. Catalog Metrics Collected
Metric	JMX MBean Name	MBean Attribute Name	Description
Catalog Exceptions	ddf.metrics.catalog:name=Exceptions	Count	The number of exceptions, of all types, thrown across all catalog queries executed.
Catalog Exceptions Federation	ddf.metrics.catalog:name=Exceptions.Federation	Count	The total number of Federation exceptions thrown across all catalog queries executed.
Catalog Exceptions Source Unavailable	ddf.metrics.catalog:name=Exceptions.SourceUnavailable	Count	The total number of `SourceUnavailable` exceptions thrown across all catalog queries executed. These exceptions occur when the source being queried is currently not available.
Catalog Exceptions Unsupported Query	ddf.metrics.catalog:name=Exceptions.UnsupportedQuery	Count	Total number of `UnsupportedQuery` exceptions thrown across all catalog queries executed. These exceptions occur when the query being executed is not supported or is invalid.
Catalog Ingest Created	ddf.metrics.catalog:name=Ingest.Created	Count	The number of catalog entries created in the Metadata Catalog.
Catalog Ingest Deleted	ddf.metrics.catalog:name=Ingest.Deleted	The number of catalog entries deleted from the Metadata Catalog.	Count
Catalog Ingest Updated	ddf.metrics.catalog:name=Ingest.Updated	Count	The number of catalog entries updated in the Metadata Catalog.
Catalog Queries	ddf.metrics.catalog:name=Queries	Count	The number of queries attempted.
Catalog Queries Comparison	ddf.metrics.catalog:name=Queries.Comparison	Count	The number of queries attempted that included a string comparison criteria as part of the search criteria, e.g., `PropertyIsLike`, `PropertyIsEqualTo`, etc.
Catalog Queries Federated	ddf.metrics.catalog:name=Queries.Federated	Count	The number of federated queries attempted.
Catalog Queries Fuzzy	ddf.metrics.catalog:name=Queries.Fuzzy	Count	The number of queries attempted that included a string comparison criteria with fuzzy searching enabled as part of the search criteria.
Catalog Queries Spatial	ddf.metrics.catalog:name=Queries.Spatial	Count	The number of queries attempted that included a spatial criteria as part of the search criteria.
Catalog Queries Temporal	ddf.metrics.catalog:name=Queries.Temporal	Count	The number of queries attempted that included a temporal criteria as part of the search criteria.
Catalog Queries Total Results	ddf.metrics.catalog:name=Queries.TotalResults	Mean	The average of the total number of results returned from executed queries. This total results data is averaged over the metric’s sample rate.
Catalog Queries Xpath	ddf.metrics.catalog:name=Queries.Xpath	Count	The number of queries attempted that included a Xpath criteria as part of the search criteria.
Catalog Resource Retrieval	ddf.metrics.catalog:name=Resource	Count	The number of resources retrieved.
Services Latency	ddf.metrics.services:name=Latency	Mean	The response time (in milliseconds) from receipt of the request at the endpoint until the response is about to be sent to the client from the endpoint. This response time data is averaged over the metric’s sample rate.

20.1.4. Source Metrics

Metrics are also collected on a per source basis for each configured Federated Source and Catalog Provider. When the source is configured, the metrics listed in the table below are automatically created. Metrics are collected for each request(whether enterprise query or a source-specific query). When the source is deleted (or renamed), the associated metrics' MBeans and Collectors are also deleted. However, the RRD file in the data/metrics directory containing the collected metrics remain indefinitely and remain accessible from the Metrics tab in the Admin Console.

In the table below, the metric name is based on the Source’s ID (indicated by <sourceId>).

Table 69. Source Metrics Collected
Metric	JMX MBean Name	MBean AttributeName	Description
Source <sourceId> Exceptions	`ddf.metrics.catalog.source:name=<sourceId>.Exceptions`	Count	A count of the total number of exceptions, of all types, thrown from catalog queries executed on this source.
Source <sourceId> Queries	`ddf.metrics.catalog.source:name=<sourceId>.Queries`	Count	A count of the number of queries attempted on this source.
Source <sourceId> Queries Total Results	`ddf.metrics.catalog.source:name=<sourceId>.Queries.TotalResults`	Mean	An average of the total number of results returned from executed queries on this source. This total results data is averaged over the metric’s sample rate.

For example, if a Federated Source was created with a name of fs-1, then the following metrics would be created for it:

Source Fs1 Exceptions
Source Fs1 Queries
Source Fs1 Queries Total Results

If this federated source is then renamed to fs-1-rename, the MBeans and Collectors for the fs-1 metrics are deleted, and new MBeans and Collectors are created with the new names:

Source Fs1 Rename Exceptions
Source Fs1 Rename Queries
Source Fs1 Rename Queries Total Results

Note that the metrics with the previous name remain on the Metrics tab because the data collected while the Source had this name remains valid and thus needs to be accessible. Therefore, it is possible to access metrics data for sources renamed months ago, i.e., until DDF is reinstalled or the metrics data is deleted from the <DDF_HOME>/data/metrics directory. Also note that the source metrics' names are modified to remove all non-alphanumeric characters and renamed in camelCase.

20.2. Metrics Reporting Application

The DDF Metrics Reporting Application provides access to historical data in several formats: a graphic, a comma-separated values file, a spreadsheet, a PowerPoint file, XML, and JSON formats for system metrics collected while DDF is running. Aggregate reports (weekly, monthly, and yearly) are also provided where all collected metrics are included in the report. Aggregate reports are available in Excel and PowerPoint formats.

To use the Metrics Reporting Application:

Navigate to the Admin Console.
Select the Platform Application.
Select the Metrics tab.

With each metric in the list, a set of hyperlinks is displayed under each column. Each column’s header is displayed with the available time ranges. The time ranges currently supported are 15 minutes, 1 hour, 1 day, 1 week, 1 month, 3 months, 6 months, and 1 year, measured from the time that the hyperlink is clicked.

All metrics reports are generated by accessing the collected metric data stored in the <DDF_HOME>/data/metrics directory. All files in this directory are generated by the JmxCollector using RRD4J, a Round Robin Database for a Java open source product. All files in this directory will have the .rrd file extension and are binary files, hence they cannot be opened directly. These files should only be accessed using the Metrics tab’s hyperlinks. There is one RRD file per metric being collected. Each RRD file is sized at creation time and will never increase in size as data is collected. One year’s worth of metric data requires approximately 1 MB file storage.

Warning

Do not remove the <DDF_HOME>/data/metrics directory or any files in the directory. If this is done, all existing metrics data will be permanently lost.

Also note that if DDF is uninstalled/re-installed, all existing metrics data will be permanently lost.

Hyperlinks are provided for each metric and each format in which data can be displayed. For example, the PNG hyperlink for 15m for the Catalog Queries metric maps to https://{FQDN}:{PORT}/services/internal/metrics/catalogQueries.png?dateOffset=900, where the dateOffset=900 indicates the previous 900 seconds (15 minutes) to be graphed.

Note that the date format will vary according to the regional/locale settings for the server.

All of the metric graphs displayed are in PNG format and are displayed on their own page. The user may use the back button in the browser to return to the Admin Console, or, when selecting the hyperlink for a graph, they can use the right mouse button in the browser to display the graph in a separate browser tab or window, which will keep the Admin Console displayed. The user can also specify custom time ranges by adjusting the URL used to access the metric’s graph. The Catalog Queries metric data may also be graphed for a specific time range by specifying the startDate and endDate query parameters in the URL.

For example, to map the Catalog Queries metric data for March 31, 6:00 am, to April 1, 2013, 11:00 am, (Arizona timezone, which is -07:00) the URL would be:

https://{FQDN}:{PORT}/services/internal/metrics/catalogQueries.png?startDate=2013-03-31T06:00:00-07:00&endDate=2013-04-01T11:00:00-07:00

Or to view the last 30 minutes of data for the Catalog Queries metric, a custom URL with a dateOffset=1800 (30 minutes in seconds) could be used:

https://{FQDN}:{PORT}/services/internal/metrics/catalogQueries.png?dateOffset=1800

20.2.1. Metrics Aggregate Reports

The Metrics tab also provides aggregate reports for the collected metrics. These are reports that include data for all of the collected metrics for the specified time range.

The aggregate reports provided are:

Weekly reports for each week up to the past four complete weeks from current time. A complete week is defined as a week from Monday through Sunday. For example, if current time is Thursday, April 11, 2013, the past complete week would be from April 1 through April 7.
Monthly reports for each month up to the past 12 complete months from current time. A complete month is defined as the full month(s) preceding current time. For example, if current time is Thursday, April 11, 2013, the past complete 12 months would be from April 2012 through March 2013.
Yearly reports for the past complete year from current time. A complete year is defined as the full year preceding current time. For example, if current time is Thursday, April 11, 2013, the past complete year would be 2012.

An aggregate report in XLS format would consist of a single workbook (spreadsheet) with multiple worksheets in it, where a separate worksheet exists for each collected metric’s data. Each worksheet would display:

the metric’s name and the time range of the collected data,
two columns: Timestamp and Value, for each sample of the metric’s data that was collected during the time range, and
a total count (if applicable) at the bottom of the worksheet.

An aggregate report in PPT format would consist of a single slideshow with a separate slide for each collected metric’s data. Each slide would display:

a title with the metric’s name.
the PNG graph for the metric’s collected data during the time range.
a total count (if applicable) at the bottom of the slide.

Hyperlinks are provided for each aggregate report’s time range in the supported display formats, which include Excel (XLS) and PowerPoint (PPT). Aggregate reports for custom time ranges can also be accessed directly via the URL:

https://{FQDN}:{PORT}/services/internal/metrics/report.<format>?startDate=<start_date_value>&endDate=<end_date_value>

where <format> is either xls or ppt and the <start_date_value> and <end_date_value> specify the custom time range for the report.

These example reports represent custom aggregate reports. NOTE: all example URLs begin with https://{FQDN}:{PORT}, which is omitted in the table for brevity.

Table 70. Example Aggregate Reports

20.2.2. Viewing Metrics

The Metrics Viewer has reports in various formats.

Navigate to the Admin Console.
Select the Platform application.
Select the Metrics tab.

Reports are organized by timeframe and output format.

Standard time increments: * 15m: 15 Minutes * 1h: 1 Hour * 1d: 1 Day * 1w: 1 Week * 1M: 1 Month * 3M: 3 Month * 6M: 6 Month * 1y: 1 Year

Custom timeframes are also available via the selectors at the bottom of the page.

Output formats: * PNG * CSV (Comma-separated values) * XLS

Note	Based on the browser’s configuration, either the `.xls` file will be downloaded or automatically displayed in Excel.

21. Action Framework

The Action Framework was designed as a way to limit dependencies between applications (apps) in a system. For instance, a feature in an app, such as an Atom feed generator, might want to include an external link as part of its feed’s entries. That feature does not have to be coupled to a REST endpoint to work, nor does it have to depend on a specific implementation to get a link. In reality, the feature does not identify how the link is generated, but it does identify whether the link works or does not work when retrieving the intended entry’s metadata. Instead of creating its own mechanism or adding an unrelated feature, it could use the Action Framework to query the OSGi container for any service that can provide a link. This does two things: it allows the feature to be independent of implementations, and it encourages reuse of common services.

The Action Framework consists of two major Java interfaces in its API:

ddf.action.Action
ddf.action.ActionProvider

Actions

Specific tasks that can be performed as services.

Action Providers

Lists of related actions that a service is capable of performing.

21.1. Action Providers

Included Action Providers

Download Resource ActionProvider: Downloads a resource to the local product cache.
IdP Logout Action Provider: Identity Provider Logout.
Karaf Logout Action: Local Logout.
LDAP Logout Action: Ldap Logout.
Overlay ActionProvider: Provides a metacard URL that transforms the metacard into a geographically aligned image (suitable for overlaying on a map).
View Metacard ActionProvider: Provides a URL to a metacard.
Metacard Transformer ActionProvider: Provides a URL to a metacard that has been transformed into a specified format.

22. Asynchronous Processing Framework

Note	This code is experimental. While this interface is functional and tested, it may change or be removed in a future version of the library.

The Asynchronous Processing Framework is a way to run plugins asynchronously. Generally, plugins that take a significant amount of processing time and whose results are not immediately required are good candidates for being asynchronously processed. A Processing Framework can either be run on the local or remote system. Once the Processing Framework finishes processing incoming requests, it may submit (Create|Update|Delete)Requests to the Catalog. The type of plugins that a Processing Framework runs are the Post-Process Plugins. The Post-Process Plugins are triggered by the Processing Post Ingest Plugin, which is a Post-Ingest Plugin. Post-Ingest Plugins are run after the metacard has been ingested into the Catalog. This feature is uninstalled by default.

Warning

The Processing Framework does not support partial updates to the Catalog. This means that if any changes are made to a metacard in the Catalog between the time asynchronous processing starts and ends, those changes will be overwritten by the ProcessingFramework updates sent back to the Catalog. This feature should be used with caution.

Processing Framework Architecture

The Asynchronous Processing Framework API Interfaces

org.codice.ddf.catalog.async.processingframework.api.internal.ProcessingFramework

org.codice.ddf.catalog.async.data.api.internal.ProcessRequest
org.codice.ddf.catalog.async.data.api.internal.ProcessResoure
org.codice.ddf.catalog.async.data.api.internal.ProcessResourceItem

Processing Framework Interface Diagram

ProcessingFramework

The ProcessingFramework is responsible for processing incoming ProcessRequests that contain a ProcessItem. A ProcessingFramework should never block. It receives its ProcessRequests from a PostIngestPlugin on all CUD operations to the Catalog. In order to determine whether or not asynchronous processing is required by the ProcessingFramework, the ProcessingFramework should mark any request it has submitted back the Catalog, otherwise a processing loop may occur. For example, the default In-Memory Processing Framework adds a POST_PROCESS_COMPLETE flag to the Catalog CUD request after processing. This flag is checked by the ProcessingPostIngestPlugin before a ProcessRequest is sent to the ProcessingFramework. For an example of a ProcessingFramework, please refer to the org.codice.ddf.catalog.async.processingframework.impl.InMemoryProcessingFramework.

ProcessRequest

A ProcessRequest contains a list of ProcessItems for the ProcessingFramework to process. Once a ProcessRequest has been processed by a ProcessingFramework, the ProcessingFramework should mark the ProcessRequest as already been processed, so that it does not process it again.

PostProcessPlugin

The PostProcessPlugin is a plugin that will be run by the ProcessingFramework. It is capable of processing ProcessCreateItems, ProcessUpdateItems, and ProcessDeleteItems.

Warning

ProcessItem

Do not implement ProcessItem directly; it is intended for use only as a common base interface for ProcessResourceItem and ProcessDeleteItem.

The ProcessItem is contained by a ProcessRequest. It can be either a ProcessCreateItem, ProcessUpdateItem, or ProcessDeleteItem.

ProcessResource

The ProcessResource is a piece of content that is attached to a metacard. The piece of content can be either local or remote.

ProcessResourceItem

The ProcessResourceItem indicates that the item being processed may have a ProcessResource associated with it.

Warning

ProcessResourceItem Warning

Do not implement ProcessResourceItem directly; it is intended for use only as a common base interface for ProcessCreateItem and ProcessUpdateItem.

ProcessCreateItem

The ProcessCreateItem is an item for a metacard that has been created in the Catalog. It contains the created metacard and, optionally, a ProcessResource.

ProcessUpdateItem

The ProcessUpdateItem is an item for a metacard that has been updated in the Catalog. It contains the original metacard, the updated metacard and, optionally, a ProcessResource.

ProcessDeleteItem

The ProcessDeleteItem is an item for a metacard that has been deleted in the Catalog. It contains the deleted metacard.

23. Eventing

Eventing Architecture

The Eventing capability of the Catalog allows endpoints (and thus external users) to create a "standing query" and be notified when a matching metacard is created, updated, or deleted.

Notably, the Catalog allows event evaluation on both the previous value (if available) and new value of a Metacard when an update occurs.

Eventing allows DDFs to receive events on operations (e.g. create, update, delete) based on particular queries or actions. Once subscribed, users will receive notifications of events such as update or create on any source.

23.1. Eventing Components

The key components of DDF Eventing include:

Subscription
Delivery Method
Event Processor

24. Migration API

Note	This code is experimental. While the interfaces and classes provided are functional and tested, they may change or be removed in a future version of the library.

DDF currently has an experimental API for making bundles migratable. Interfaces and classes in platform/migration/platform-migratable-api are used by the system to identify bundles that provide implementations for export and import operations.

The migration API provides a mechanism for bundles to handle exporting data required to clone or backup/restore a DDF system. The migration process is meant to be flexible, so an implementation of org.codice.ddf.migration.Migratable can handle exporting data for a single bundle or groups of bundles such as applications. For example, the org.codice.ddf.platform.migratable.impl.PlatformMigratable handles exporting core system files for the Platform application. Each migratable must provide a unique identifier via its getId() method used by the migration API to uniquely identify the migratable between exports and imports.
DDF defines migratables of its own to export/import all configurations stored in org.osgi.service.cm.ConfigurationAdmin.

These do not need to be handled by implementations of org.codice.ddf.migration.Migratable.

An export and an import operation can be performed through the Command Console.

When an export operation is processed, the migration API will do a look-up for all registered OSGi services that are implementing Migratable and call their doExport() method. As part of the exported data, information about the migratable as required by the org.codice.ddf.platform.services.common.Describable interface will be included. In particular the version string returned will help the migration API identify the version of the exported data from the corresponding migratable and must be provided as a non-blank string.

When an import operation is processed when the current DDF version matches the exported @DDF version, the migration API will do another look-up for all registered OSGi services that are implementing Migratable and call their doImport() or doIncompatibleImport() methods based on whether the recorded version string at export time is equal to the version string currently provided by the migratable or not. The doMissingImport() method will be called instead of one of the other two methods when the migration API detects that the corresponding migratable data is missing from the exported data. Any migratables that are tagged using the OptionalMigratable tag interface will automatically be skipped unless otherwise specified when the import phase is initiated.

When an import operation is processed when the current DDF version does not the exported @DDF version, the migration API will do a look-up for all registered OSGi services that are implementing Migratable and call their doVersionUpgradeImport() method.

The services that implement the migratable interface will be called one at a time based on their service ranking order, and do not need to be thread safe. A bundle or a feature can have as many services implementing the interfaces as needed.

24.1. The Migration API Interfaces and Classes

org.codice.ddf.migration.Migratable
org.codice.ddf.migration.OptionalMigratable
org.codice.ddf.migration.MigrationContext
org.codice.ddf.migration.ExportMigrationContext
org.codice.ddf.migration.ImportMigrationContext
org.codice.ddf.migration.MigrationEntry
org.codice.ddf.migration.ExportMigrationEntry
org.codice.ddf.migration.ImportMigrationEntry
org.codice.ddf.migration.MigrationOperation
org.codice.ddf.migration.MigrationReport
org.codice.ddf.migration.MigrationMessage
org.codice.ddf.migration.MigrationException
org.codice.ddf.migration.MigrationWarning
org.codice.ddf.migration.MigrationInformation
org.codice.ddf.migration.MigrationSuccessfulInformation

24.1.1. `Migratable`

The contract for a migratable is stored here. This is the only interface that should be implemented by implementers and registered as an OSGi service. All other interfaces will be implemented by the migration API that provides support for migratables.

The org.codice.ddf.migration.Migratable interface defines these methods:

String getId()
String getVersion()
String getTitle()
String getDescription()
String getOrganization()
void doExport(ExportMigrationContext context)
void doImport(ImportMigrationContext context)
void doIncompatibleImport(ImportMigrationContext context)
void doVersionUpgradeImport(ImportMigrationContext context)
void doMissingImport(ImportMigrationContext context)

The getId() method returns a unique identifier for this migratable that must remain constant between the export and the import operations in order for the migration API to correlate the exported data with the migratable during the import operation. It must be unique across all migratables.
The getVersion() method returns a unique version string which is meant to identify the version of the data exported or supported at import time by the migratable. It cannot be blank and its format is left to the migratable. The only noticeable requirement is that when the string compares equal using the String.equals() method, the migration API will call doImport() instead of doIncompatibleImport() to restore previously exported data for the migratable.
The getTitle() method returns a simple title for the migratable.
The getDescription() method returns a short description of the type of data exported by the migratable.
The getOrganization() method provides the name of the organization responsible for the migratable.
The doExport() method is called by the migration API along with a context for the current export operation to store data.
The doImport() method is called by the migration API along with a context for the current import operation when the version of exported data matches the current version reported by the migratable. This method can be used to restore previously exported data.
The doIncompatibleImport() method is called to restore incompatible data which might require transformation. It is provided a context for the current import operation and the previously exported version. It can then proceed with restoring incompatible data which might require transformation.
The doVersionUpgradeImport() method is called to restore data from a different DDF version which might require transformation. It is provided a context for the current import operation and the previously exported version.
Finally, the doMissingImport() method will be called along with the context for the current import operation when data had not been exported for the corresponding migratable. This will be the case when a migratable is later introduced in the software distribution.

In order to create a Migratable for a module of the system, the org.codice.ddf.migration.Migratable interface must be implemented and the implementation must be registered under the org.codice.ddf.migration.Migratable interface as an OSGi service in the OSGi service registry. Creating an OSGi service allows for the migration API to lookup all implementations of org.codice.ddf.migration.Migratable and command them to export or import.

24.1.2. `OptionalMigratable`

This interface is designed as a tagged interface to identify optional migratables. An optional migratable will be skipped by default during the import phase. It can still be manually marked as mandatory when initiating the import phase.

24.1.3. `MigrationContext`

The org.codice.ddf.migration.MigrationContext provides contextual information about an operation in progress for a given migratable. This is a sort of sandbox that is unique to each migratable. This interface defines the following methods:

MigrationReport getReport()
String getId()
Optional<String> getMigratableVersion()

The getReport() method returns a migration report that can be used to record messages while processing an export or an import operation.
The getId() method returns the identifier for the currently processing migratable. The getMigratableVersion() method returns the version for the currently processing migratable.

24.1.4. `ExportMigrationContext`

The export migration context provides methods for creating new migration entries and system property referenced migration entries to track exported migration files for a given migratable while processing an export migration operation. It defines the following methods:

Optional<ExportMigrationEntry> getSystemPropertyReferencedEntry(String name)
Optional<ExportMigrationEntry> getSystemPropertyReferencedEntry(String name, BiPredicate<MigrationReport, String> validator)
ExportMigrationEntry getEntry(Path path)
Stream<ExportMigrationEntry> entries(Path path)
Stream<ExportMigrationEntry> entries(Path path, PathMatcher filter)
Stream<ExportMigrationEntry> entries(Path path, boolean recurse)
Stream<ExportMigrationEntry> entries(Path path, boolean recurse, PathMatcher filter)

The getSystemPropertyReferencedEntry() methods create a migration entry to track a file referenced by a given system property value.
The getEntry() method creates a migration entry given the path for a specific file or directory.
The entries() methods create multiple entries corresponding to all files recursively (or not) located underneath a given path with an optional path matcher to filter which files to create entries for.

Once an entry is created, it is not stored with the exported data. It is the migratable’s responsibility to store the data using one of the entry’s provided methods. Entries are uniquely identified using a relative path and are specific to each migratable meaning that an entry with the same path in two migratables will not conflict with each other. Each migratable is given its own context (a.k.a. sandbox) to work with.

24.1.5. `ImportMigrationContext`

The import migration context provides methods for retrieving migration entries and system property referenced migration entries corresponding to exported files for a given migratable while processing an import migration operation. It defines the following methods:

Optional<ImportMigrationEntry> getSystemPropertyReferencedEntry(String name)
ImportMigrationEntry getEntry(Path path)
Stream<ImportMigrationEntry> entries(Path path)
Stream<ImportMigrationEntry> entries(Path path, PathMatcher filter)

The getSystemPropertyReferencedEntry() method retrieves a migration entry for a file that was referenced by a given system property value.
The getEntry() method retrieves a migration entry given the path for a specific file or directory.
The entries() methods retrieve multiple entries corresponding to all exported files recursively located underneath a given relative path with an optional path matcher to filter which files to retreive entries for.

Once an entry is retrieved, its exported data is not restored. It is the migratable’s responsibility to restore the data using one of the entry’s provided methods. Entries are uniquely identified using a relative path and are specific to each migratable meaning that an entry with the same path in two migratables will not conflict with each other. Each migratable is given its own context (a.k.a. sandbox) to work with.

24.1.6. `MigrationEntry`

This interface provides supports for exported files. It defines the following methods:

MigrationReport getReport()
String getId()
String getName()
Path getPath()
boolean isDirectory()
boolean isFile()
long getLastModifiedTime()

The getReport() method provides access to the associated migration report where messages can be recorded.
The getId() method returns the identifier for the migratable responsible for this entry.
The getName() method provides the unique name for this entry in an OS-independent way.
The getPath() method provides the unique path to the corresponding file for this entry in an OS-specific way.
The isDirectory() method indicates if the entry represents a directory. The isFile() method indicates if the entry represents a file. The getLastModifiedTime() method provides the last modification time for the corresponding file or directory as available when the file or directory is exported.

24.1.7. `ExportMigrationEntry`

The export migration entry provides additional methods available for entries created at export time. It defines the following methods:

Optional<ExportMigrationEntry> getPropertyReferencedEntry(String name)
Optional<ExportMigrationEntry> getPropertyReferencedEntry(String name, BiPredicate<MigrationReport, String> validator)
boolean store()
boolean store(boolean required)
boolean store(PathMatcher filter)
boolean store(boolean required, PathMatcher filter)
boolean store(BiThrowingConsumer<MigrationReport, OutputStream, IOException> consumer)
OutputStream getOutputStream() throws IOException

The getPropertyReferencedEntry() methods create another migration entry for a file that was referenced by a given property value in the file represented by this entry.
The store() and store(boolean required) methods will automatically copy the content of the corresponding file as part of the export making sure the file exists (if required) on disk otherwise an error will be recorded. If the path represents a directory then all files recursively found under the path will be automatically exported.
The store(PathMatcher filter) and store(boolean required, PathMatcher filter) methods will automatically copy the content of the corresponding file if it matches the filter as part of the export making sure the file exists (if required) on disk otherwise an error will be recorded. If the path represents a directory then all matching files recursively found under the path will be automatically exported.
The store(BiThrowingConsumer<MigrationReport, OutputStream, IOException> consumer) method allows the migratable to control the export process by specifying a callback consumer that will be called back with an output stream where the data can be writen to instead of having a file on disk being copied by the migration API. The OutputStream getOutputStream() method provides access to the low-level output stream where the migratable can write data directly as opposed to having a file on disk copied automatically.

24.1.8. `ImportMigrationEntry`

The import migration entry provides additional methods available for entries retrieved at import time. It defines the following methods:

Optional<ImportMigrationEntry> getPropertyReferencedEntry(String name)
boolean restore()
boolean restore(boolean required)
boolean restore(PathMatcher filter)
boolean restore(boolean required, PathMatcher filter)
boolean restore(BiThrowingConsumer<MigrationReport, Optional<InputStream>, IOException> consumer)
Optional<InputStream getInputStream() throws IOException

The getPropertyReferencedEntry() method retrieves another migration entry for a file that was referenced by a given property value in the file represented by this entry.
The restore() and restore(boolean required) methods will automatically copy the exported content of the corresponding file back to disk if it was exported; otherwise an error will be recorded. If the path represents a directory then all file entries originally recursively exported under this entry’s path will be automatically imported. If the directory had been completely exported using one of the store() or store(boolean required) methods then in addition to restoring all entries recursively, calling this method will also remove any existing files or directories that were not on the original system.
The restore(PathMatcher filter) and restore(boolean required, PathMatcher filter) methods will automatically copy the exported content of the corresponding file if it matches the filter back to disk if it was exported; otherwise an error will be recorded. If the path represents a directory then all matching file entries originally recursively exported under this entry’s path will be automatically imported.
The restore(BiThrowingConsumer<MigrationReport, Optional<InputStream>, IOException> consumer) method allows the migratable to control the import process by specifying a callback consumer that will be called back with an optional input stream (empty if the data was not exported) where the data can be read from instead of having a file on disk being created or updated by the migration API.
The Optional<InputStream> getInputStream() method provides access to the optional low-level input stream (empty if the data was not exported) where the migratable can read data directly as opposed to having a file on disk created or updated automatically.

24.1.9. `MigrationOperation`

The org.codice.ddf.migration.MigrationOperation provides a simple enumeration for identifying the various migration operations available.

24.1.10. `MigrationReport`

The org.codice.ddf.migration.MigrationReport interface provides information about the execution of a migration operation. It defines the following methods:

MigrationOperation getOperation()
Instant getStartTime()
Optional<Instant> getEndTime()
MigrationReport record(String msg)
MigrationReport record(String format, @Nullable Object… args)
MigrationReport record(MigrationMessage msg)
MigrationReport doAfterCompletion(Consumer<MigrationReport> code)
Stream<MigrationMessage> messages()
default Stream<MigrationException> errors()
Stream<MigrationWarning> warnings()
Stream<MigrationInformation> infos()
boolean wasSuccessful()
boolean wasSuccessful(@Nullable Runnable code)
boolean wasIOSuccessful(@Nullable ThrowingRunnable<IOException> code) throws IOException
boolean hasInfos()
boolean hasWarnings()
boolean hasErrors()
void verifyCompletion()

The getOperation() method provides the type of migration operation (i.e. export or import) currently in progress.
The getStartTime() method provides the time at which the corresponding operation started.
The getEndTime() method provides the optional time at which the corresponding operation ended. The time is only available if the operation has ended.
The record() methods enable messages to be recorded with the report. Messages are displayed on the console for the administrator.
The doAfterCompletion() methods enable code to be registered such that it is invoked at the end before a successful result is returned. Such code can still affect the result of the operation.
The messages() method provides access to all recorded messages so far.
The errors() method provides access to all recorded error messages so far.
The warnings() method provides access to all recorded warning messages so far.
The infos() method provides access to all recorded informational messages so far.
The wasSuccessful() method provides a quick check to see if the report is successful. A successful report might have warnings recorded but cannot have errors recorded.
The wasSuccessful(Runnable code) method allows code to be executed. It will return true if no new errors are recorded as a result of executing the provided code. The `wasIOSuccessful(ThrowingRunnable<IOException> code) method allows code to be executed which can throw I/O exceptions which are automatically recorded as errors. It will return true if no new errors are recorded as a result of executing the provided code. The `hasInfos() method will return true if at least one information message has been recorded so far.
The hasWarnings() method will return true if at least one warning message has been recorded so far.
The hasErrors() method will return true if at least one error message has been recorded so far.
The `verifyCompletion() method will verify if the report is successful and if not, it will throw back the first recorded exception and attach as suppressed exceptions all other recorded exceptions.

24.1.11. `MigrationMessage`

The `org.codice.ddf.migration.MigrationException is defined as a base class for all recordable messages during migration operations. It defines the following methods:

String getMessage()

The getMessage() method provides a message for the corresponding exception, warning, or info that will be displayed to the administrator on the console.

24.1.12. `MigrationException`

An org.codice.ddf.migration.MigrationException should be thrown when an unrecoverable exception occurs that prevents the export or the import operation from continuing. It is also possible to simply record one or many exception(s) with the migration report in order to fail the export or import operation while not aborting it right away. This provides for the ability to record as many errors as possible and report all of them back to the administrator. All migration exception messages are displayed to the administrator.

24.1.13. `MigrationWarning`

An org.codice.ddf.migration.MigrationWarning should be used when a migratable wants to warn the administrator that certain aspects of the export or the import may cause problems. For example, if an absolute path is encountered, that path may not exist on the target system and cause the installation to fail. All migration warning messages are displayed to the administrator.

24.1.14. `MigrationInformation`

An org.codice.ddf.migration.MigrationInformation should be used when a migratable simply wants to provide useful information to the administrator. All migration information messages are displayed to the administrator.

24.1.15. `MigrationSuccessfulInformation`

The org.codice.ddf.migration.MigrationSuccessfulInformation can be used to further qualify an information message as representing the success of an operation.

25. Security Framework

The DDF Security Framework utilizes Apache Shiro as the underlying security framework. The classes mentioned in this section will have their full package name listed, to make it easy to tell which classes come with the core Shiro framework and which are added by DDF.

25.1. Subject

ddf.security.Subject <extends> org.apache.shiro.subject.Subject

The Subject is the key object in the security framework. Most of the workflow and implementations revolve around creating and using a Subject. The Subject object in DDF is a class that encapsulates all information about the user performing the current operation. The Subject can also be used to perform permission checks to see if the calling user has acceptable permission to perform a certain action (e.g., calling a service or returning a metacard). This class was made DDF-specific because the Shiro interface cannot be added to the Query Request property map.

Table 71. Implementations of Subject:
Classname	Description
ddf.security.impl.SubjectImpl	Extends `org.apache.shiro.subject.support.DelegatingSubject`

25.1.1. Security Manager

ddf.security.service.SecurityManager

The Security Manager is a service that handles the creation of Subject objects. A proxy to this service should be obtained by an endpoint to create a Subject and add it to the outgoing QueryRequest. The Shiro framework relies on creating the subject by obtaining it from the current thread. Due to the multi-threaded and stateless nature of the DDF framework, utilizing the Security Manager interface makes retrieving Subjects easier and safer.

Table 72. Implementations of Security Managers:
Classname	Description
`ddf.security.service.SecurityManagerImpl`	This implementation of the Security Manager handles taking in both `org.apache.shiro.authc`. AuthenticationToken and `org.apache.cxf.ws.security.tokenstore.SecurityToken` objects.

25.1.2. Realms

DDF uses Apache Shiro for the concept of Realms for Authentication and Authorization. Realms are components that access security data such as such as users or permissions.

25.1.2.1. Authenticating Realms

org.apache.shiro.realm.AuthenticatingRealm

Authenticating Realms are used to authenticate an incoming Authentication Token and return Authentication Info on successful authentication. This Authentication Info is used by the Shiro framework to put together a resulting Subject. A Subject represents the application user and contains all available security-relevant information about that user.

Table 73. Implementations of Authenticating Realms in DDF:
Classname	Description
`org.codice.ddf.security.guest.realm.GuestRealm`	This realm checks if Guest access is allowed on the incoming Authentication Token, and if so the Guest realm returns the Guest Authentication Info.
`org.codice.ddf.security.oidc.realm.OidcRealm`	This realm takes in any OIDC/OAuth credentials found on the incoming Authentication Token, and if so resolves the ID_Token using those credentials. The ID_Token is then used to put together the resulting Authentication Info.
`ddf.security.realm.sts.StsRealm`	This realm delegates authentication to the Secure Token Service (STS). It creates a `RequestSecurityToken` message from the incoming Authentication Token and converts a successful STS response into Authentication Info.

25.1.2.2. Authorizing Realms

org.apache.shiro.realm.AuthorizingRealm

Authorizing Realms are used to perform authorization on the current Subject. These are used when performing both service authorization and filtering. They are passed in the AuthorizationInfo of the Subject along with the permissions of the object wanting to be accessed. The response from these realms is a true (if the Subject has permission to access) or false (if the Subject does not).

Table 74. Other implementations of the Security API within DDF
Classname	Description
`org.codice.ddf.platform.filter.delegate.DelegateServletFilter`	The `DelegateServletFilter` detects any servlet filters that have been exposed as OSGi services implementing `org.codice.ddf.platform.filter.SecurityFilter` and places them in-order in front of any servlet or web application running on the container.
`org.codice.ddf.security.filter.websso.WebSSOFilter`	This filter is the main security filter that works with a number of handlers to protect a variety of web contexts, each using different authentication schemes and policies. It attaches an Authentication Token to the request by either checking the session or calling the configured Security Handlers.
`org.codice.ddf.security.handler.basic.BasicAuthenticationHandler`	Checks for basic authentication credentials in the http request header. If no credentials are found, it supports the acquisition of basic credentials on user-agent requests.
`org.codice.ddf.security.handler.pki.PKIHandler`	Handler for PKI based authentication. X509 chain will be extracted from the HTTP request.
`org.codice.security.idp.client.IdpHandler`	Handler for IdP/SAML based authentication. If no credentials are found, it supports the acquisition of credentials through the configured SAML IdP.
`org.codice.ddf.security.handler.oidc.OidcHandler`	Handler for OIDC based authentication. If no credentials are found, and is a user-agent request, this handler supports the acquisition of credentials through the configured OIDC IdP.
`org.codice.ddf.security.handler.oauth.OAuthHandler`	Handler for OAuth based authentication. Does not support the acquisition of credentials.
`org.codice.ddf.security.filter.login.LoginFilter`	This filter runs immediately after the WebSSOFilter and exchanges an Authentication Token found in the request with a Subject via Shiro.
`org.codice.ddf.security.filter.authorization.AuthorizationFilter`	This filter runs immediately after the `LoginFilter` and checks any permissions assigned to the web context against the attributes of the Subject via Shiro.
`org.apache.shiro.realm.AuthenticatingRealm`	This is an abstract authenticating realm that exchanges an `org.apache.shiro.authc.AuthenticationToken` for a `org.apache.shiro.authc.AuthenticationInfo`, which is used by the Shiro framework to put together a `ddf.security.Subject`.
`ddf.security.service.AbstractAuthorizingRealm`	This is an abstract authorizing realm that takes care of caching and parsing the Subject’s `AuthorizingInfo` and should be extended to allow the implementing realm to focus on making the decision.
`ddf.security.pdp.realm.AuthZRealm`	This realm performs the authorization decision and may or may not delegate out to the external XACML processing engine. It uses the incoming permissions to create a decision. However, it is possible to extend this realm using the ddf.security.policy.extension.PolicyExtension interface. This interface allows an integrator to add additional policy information to the PDP that can’t be covered via its generic matching policies. This approach is often easier to configure for those that are not familiar with XACML.
`org.codice.ddf.security.validator.*`	A number of validators are provided for X.509 and Username tokens.

Warning

An update was made to the IdpHandler to pass SAML assertions through the Authorization HTTP header. Cookies are still accepted and processed to maintain legacy federation compatibility, but assertions are sent in the header on outbound requests. While a machine’s identity will still federate between versions, a user’s identity will ONLY be federated when a DDF version 2.7.x server communicates with a DDF version 2.8.x+ server, or between two servers whose versions are 2.8.x or higher.

25.2. Security Core

The Security Core application contains all of the necessary components that are used to perform security operations (authentication, authorization, and auditing) required in the framework.

25.2.1. Security Core API

The Security Core API contains all of the DDF APIs that are used to perform security operations within DDF.

25.2.1.1. Installing the Security Core API

The Security Services App installs the Security Core API by default. Do not uninstall the Security Core API as it is integral to system function and all of the other security services depend upon it.

25.2.1.2. Configuring the Security Core API

The Security Core API has no configurable properties.

25.2.2. Security Core Implementation

The Security Core Implementation contains the reference implementations for the Security Core API interfaces that come with the DDF distribution.

25.2.2.1. Installing the Security Core Implementation

The Security Core app installs this bundle by default. It is recommended to use this bundle as it contains the reference implementations for many classes used within the Security Framework.

25.2.2.2. Configuring the Security Core Implementation

The Security Core Implementation has no configurable properties.

25.2.3. Security Core Commons

The Security Core Commons bundle contains helper and utility classes that are used within DDF to help with performing common security operations. Most notably, this bundle contains the ddf.security.common.audit.SecurityLogger class that performs the security audit logging within DDF.

25.2.3.1. Configuring the Security Core Commons

The Security Core Commons bundle has no configurable properties.

25.3. Security IdP

The Security IdP application provides service provider handling that satisfies the SAML 2.0 Web SSO profile in order to support external IdPs (Identity Providers) or SPs (Service Providers). This capability allows use of DDF as the SSO solution for an entire enterprise.

Table 75. Security IdP Components
Bundle Name	Located in Feature	Description
`security-idp-client`	`security-idp`	The IdP client that interacts with the specified Identity Provider.
`security-idp-server`	`security-idp`	An internal Identity Provider solution.

Note	Limitations The internal Identity Provider solution should be used in favor of any external solutions until the IdP Service Provider fully satisfies the SAML 2.0 Web SSO profile .

25.4. Security Encryption

The Security Encryption application offers an encryption framework and service implementation for other applications to use. This service is commonly used to encrypt and decrypt default passwords that are located within the metatype and Admin Console.

The encryption service and encryption command, which are based on tink , provide an easy way for developers to add encryption capabilities to DDF.

25.4.1. Security Encryption API

The Security Encryption API bundle provides the framework for the encryption service. Applications that use the encryption service should use the interfaces defined within it instead of calling an implementation directly.

25.4.1.1. Installing Security Encryption API

This bundle is installed by default as part of the security-encryption feature. Many applications that come with DDF depend on this bundle and it should not be uninstalled.

25.4.1.2. Configuring the Security Encryption API

The Security Encryption API has no configurable properties.

25.4.2. Security Encryption Implementation

The Security Encryption Implementation bundle contains all of the service implementations for the Encryption Framework and exports those implementations as services to the OSGi service registry.

25.4.2.1. Installing Security Encryption Implementation

This bundle is installed by default as part of the security-encryption feature. Other projects are dependent on the services this bundle exports and it should not be uninstalled unless another security service implementation is being added.

25.4.2.2. Configuring Security Encryption Implementation

The Security Encryption Implementation has no configurable properties.

25.4.3. Security Encryption Commands

The Security Encryption Commands bundle enhances the DDF system console by allowing administrators and integrators to encrypt and decrypt values directly from the console.

The security:encrypt command allows plain text to be encrypted using AES for encryption. It uses randomly generated keys and associated data that are created when the system is installed, and can be found in the <DDF_HOME>/etc/keysets directory. This is useful when displaying password fields in a GUI.

Below is an example of the security:encrypt command used to encrypt the plain text "myPasswordToEncrypt". The output, bR9mJpDVo8bTRwqGwIFxHJ5yFJzatKwjXjIo/8USWm8=, is the encrypted value.

ddf@local>security:encrypt myPasswordToEncrypt

bR9mJpDVo8bTRwqGwIFxHJ5yFJzatKwjXjIo/8USWm8=

25.4.3.1. Installing the Security Encryption Commands

This bundle is installed by default with the security-encryption feature. This bundle is tied specifically to the DDF console and can be uninstalled if not needed. When uninstalled, however, administrators will not be able to encrypt and decrypt data from the console.

25.4.3.2. Configuring the Security Encryption Commands

The Security Encryption Commands have no configurable properties.

25.5. Security LDAP

The DDF LDAP application allows the user to configure either an embedded or a standalone LDAP server. The provided features contain a default set of schemas and users loaded to help facilitate authentication and authorization testing.

25.5.1. Embedded LDAP Server

DDF includes an embedded LDAP server (OpenDJ) for testing and demonstration purposes.

Warning

The embedded LDAP server is intended for testing purposes only and is not recommended for production use.

25.5.1.1. Installing the Embedded LDAP Server

The embedded LDAP server is not installed by default with a standard installation.

Navigate to the Admin Console.
Select the System tab.

25.5.1.6. Starting and Stopping the Embedded LDAP

The embedded LDAP application installs a feature with the name ldap-embedded. Installing and uninstalling this feature will start and stop the embedded LDAP server. This will also install a fresh instance of the server each time. If changes need to persist, stop then start the embedded-ldap-opendj bundle (rather than installing/uninstalling the feature).

All settings, configurations, and changes made to the embedded LDAP instances are persisted across DDF restarts. If DDF is stopped while the LDAP feature is installed and started, it will automatically restart with the saved settings on the next DDF start.

25.5.1.7. Limitations of the Embedded LDAP

Current limitations for the embedded LDAP instances include:

Inability to store the LDAP files/storage outside of the DDF installation directory. This results in any LDAP data (i.e., LDAP user information) being lost when the ldap-embedded feature is uninstalled.
Cannot be run standalone from DDF. In order to run embedded-ldap, the DDF must be started.

25.6. Security PDP

The Security Policy Decision Point (PDP) module contains services that are able to perform authorization decisions based on configurations and policies. In the Security Framework, these components are called realms, and they implement the org.apache.shiro.realm.Realm and org.apache.shiro.authz.Authorizer interfaces. Although these components perform decisions on access control, enforcement of this decision is performed by components within the notional PEP application.

25.6.1. Security PDP AuthZ Realm

The Security PDP AuthZ Realm exposes a realm service that makes decisions on authorization requests using the attributes stored within the metacard to determine if access should be granted. This realm can use XACML and will delegate decisions to an external processing engine if internal processing fails. Decisions are first made based on the "match-all" and "match-one" logic. Any attributes listed in the "match-all" or "match-one" sections will not be passed to the XACML processing engine and they will be matched internally. It is recommended to list as many attributes as possible in these sections to avoid going out to the XACML processing engine for performance reasons. If it is desired that all decisions be passed to the XACML processing engine, remove all of the "match-all" and "match-one" configurations. The configuration below provides the mapping between user attributes and the attributes being asserted - one map exists for each type of mapping (each map may contain multiple values).

Match-All Mapping:: This mapping is used to guarantee that all values present in the specified metacard attribute exist in the corresponding user attribute. Match-One Mapping:: This mapping is used to guarantee that at least one of the values present in the specified metacard attribute exists in the corresponding user attribute.

25.6.1.1. Configuring the Security PDP AuthZ Realm

Navigate to the Admin Console.
Select Security Application.
Select Configuration tab.
Select Security AuthZ Realm.

See Security AuthZ Realm for all possible configurations.

25.6.2. Guest Interceptor

The goal of the GuestInterceptor is to allow non-secure clients (such as SOAP requests without security headers) to access secure service endpoints.

All requests to secure endpoints must satisfy the WS-SecurityPolicy that is included in the WSDL.

Rather than reject requests without user credentials, the guest interceptor detects the missing credentials and inserts an assertion that represents the "guest" user. The attributes included in this guest user assertion are configured by the administrator to represent any unknown user on the current network.

25.6.2.1. Installing Guest Interceptor

The GuestInterceptor is installed by default with Security Application.

25.6.2.2. Configuring Guest Interceptor

Configure the Guest Interceptor from the Admin Console:

Navigate to the Admin Console at https://{FQDN}:{PORT}/admin
Select the Security application.
Select the Configuration tab.
Select the Guest Claims Configuration configuration.
Select the + next to Attributes to add a new attribute.
Add any additional attributes that will apply to every user.
Select Save changes.

Once these configurations have been added, the GuestInterceptor is ready for use. Both secure and non-secure requests will be accepted by all secure DDF service endpoints.

25.7. Web Service Security Architecture

The Web Service Security (WSS) functionality that comes with DDF is integrated throughout the system. This is a central resource describing how all of the pieces work together and where they are located within the system.

DDF comes with a Security Framework and Security Services. The Security Framework is the set of APIs that define the integration with the DDF framework and the Security Services are the reference implementations of those APIs built for a realistic end-to-end use case.

25.7.1. Securing REST

Security Architecture

The Jetty Authenticator is the topmost handler of all requests. It initializes all Security Filters and runs them in order according to service ranking:

The Web SSO Filter reads from the web context policy manager and functions as the first decision point. If the request is from a whitelisted context, no further authentication is needed and the request skips through the rest of the security filters to the desired endpoint.

If the context is not on the whitelist, the filter will first attempt to pull authentication information off of the session. If authentication information cannot be found on the session, the filter will then attempt to get an authentication handler for the context. The filter loops through all configured context handlers until one signals that it has found authentication information that it can use to build a token. This configuration can be changed by modifying the web context policy manager configuration. If unable to resolve the context, the filter will return an authentication error and the process stops. If a handler is successfully found, an auth token is assigned and the request continues to the login filter.

The Login Filter receives an authentication token and returns a subject. To retrieve the subject, the authentication token is sent through Shiro to the configured authenticating realms. The realms will take the authentication token and attempt to return authentication info to the Shiro framework in order to put together a subject.
If the Subject is returned, the request moves to the AuthZ Filter to check permissions on the user. If the user has the correct permissions to access that web context, the request can hit the endpoint.

SAML IdP Architecture

The IdP Handler is a configured handler on the Web SSO Filter just like the other handlers in the previous diagram. The IdP Handler and the Assertion Consumer Service are both part of the IdP client that can be used to interface with any compliant SAML 2.0 Web SSO Identity Provider.

The Metadata Exchange happens asynchronously from any login event. The exchange can happen via HTTP or File, or the metadata XML itself can be pasted into the configuration for either the IdP client or the IdP server that the system ships with. The metadata contains information about what bindings are accepted by the client or server and whether or not either expects messages to be signed, etc. The redirect from the Assertion Consumer Service to the Endpoint will cause the client to pass back through the entire filter chain, which will get caught at the Has Session point of the WebSsoFilter. The request will proceed through the rest of the filters as any other connection would in the previous diagram.

Unauthenticated non-browser clients that pass the HTTP headers signaling that they understand SAML ECP can authenticate via that mechanism as explained below.

SAML ECP Architecture

SAML ECP can be used to authenticate a non-browser client or non-person entity (NPE). This method of authentication is useful when there is no human in the loop, but authentication with an IdP is still desired. The IdP Handler will send a PAOS (Reverse SOAP) request as an initial response back to the Secure Client, assuming the client has sent the necessary HTTP headers to declare that it supports this function. That response does not complete the request/response loop, but is instead caught by a SOAP intermediary, which is implemented through a CXF interceptor. The PAOS response contains an <AuthNRequest> request message, which is intended to be rerouted to an IdP via SOAP. The SOAP intermediary will then contact an IdP (selection of the IdP is not covered by the spec). The IdP will either reject the login attempt, or issue a Signed <Response> that is to be delivered to the Assertion Consumer Service by the intermediary. The method of logging into the IdP is not covered by the spec and is up to the implementation. The SP is then signaled to supply the originally requested resource, assuming the signed Response message is valid and the user has permission to view the resource.

The ambiguity in parts of the spec with regard to selecting an IdP to use and logging into that IdP can lead to integration issues between different systems. However, this method of authentication is not necessarily expected to work by default with anything other than other instances of DDF. It does, however, provide a starting point that downstream projects can leverage in order to provide ECP based authentication for their particular scenario or to connect to other systems that utilize SAML ECP.

25.7.2. Securing SOAP

25.7.2.1. SOAP Secure Client

When calling to an endpoint from a SOAP secure client, it first requests the WSDL from the endpoint and the SOAP endpoint returns the WSDL. The client then calls to STS for authentication token to proceed. If the client receives the token, it makes a secure call to the endpoint and receives results.

25.7.2.2. Policy-unaware SOAP Client

If calling an endpoint from a non-secure client, at the point the of the initial call, the Guest Interceptor catches the request and prepares it to be accepted by the endpoint.

First, the interceptor reads the configured policy, builds a security header, and gets an anonymous SAML assertion. Using this, it makes a getSubject call which is sent through Shiro to the STS realm. Upon success, the STS realm returns the subject and the call is made to the endpoint.

25.8. Security PEP

The Security Policy Enforcement Point (PEP) application contains bundles that allow for policies to be enforced at various parts of the system, for example: to reach contexts, view metacards, access catalog operations, and others.

25.8.1. Security PEP Interceptor

The Security PEP Interceptor bundle contains the ddf.security.pep.interceptor.PEPAuthorizingInterceptor class. This class uses CXF to intercept incoming SOAP messages and enforces service authorization policies by sending the service request to the security framework.

25.8.1.1. Installing the Security PEP Interceptor

This bundle is not installed by default but can be added by installing the security-pep-serviceauthz feature.

Warning

To perform service authorization within a default install of DDF, this bundle MUST be installed.

25.8.1.2. Configuring the Security PEP Interceptor

The Security PEP Interceptor has no configurable properties.

25.9. Filtering

Metacard filtering is performed by the Filter Plugin after a query has been performed, but before the results are returned to the requestor.

Each metacard result will contain security attributes that are populated by the CatalogFramework based on the PolicyPlugins (Not provided! You must create your own plugin for your specific metadata!) that populates this attribute. The security attribute is a HashMap containing a set of keys that map to lists of values. The metacard is then processed by a filter plugin that creates a KeyValueCollectionPermission from the metacard’s security attribute. This permission is then checked against the user subject to determine if the subject has the correct claims to view that metacard. The decision to filter the metacard eventually relies on the PDP (feature:install security-pdp-authz). The PDP returns a decision, and the metacard will either be filtered or allowed to pass through.

The security attributes populated on the metacard are completely dependent on the type of the metacard. Each type of metacard must have its own PolicyPlugin that reads the metadata being returned and returns the metacard’s security attribute. If the subject permissions are missing during filtering, all resources will be filtered.

Example (represented as simple XML for ease of understanding):

  <metacard>
    <security>
        <map>
            <entry key="entry1" value="A,B" />
            <entry key="entry2" value="X,Y" />
            <entry key="entry3" value="USA,GBR" />
            <entry key="entry4" value="USA,AUS" />
        </map>
    </security>
</metacard>

  <user>
    <claim name="claim1">
        <value>A</value>
        <value>B</value>
    </claim>
    <claim name="claim2">
        <value>X</value>
        <value>Y</value>
    </claim>
    <claim name="claim3">
        <value>USA</value>
    </claim>
    <claim name="claim4">
        <value>USA</value>
    </claim>
</user>

In the above example, the user’s claims are represented very simply and are similar to how they would actually appear in a SAML 2 assertion. Each of these user (or subject) claims will be converted to a KeyValuePermission object. These permission objects will be implied against the permission object generated from the metacard record. In this particular case, the metacard might be allowed if the policy is configured appropriately because all of the permissions line up correctly.

To enable filtering on a new type of record, implement a PolicyPlugin that is able to read the string metadata contained within the metacard record. Note that, in DDF, there is no default plugin that parses a metacard. A plugin must be created to create a policy for the metacard.

25.10. Expansion Service

The Expansion Service and its corresponding expansion-related commands provide an easy way for developers to add expansion capabilities to DDF during user attribute and metadata card processing. In addition to these two defined uses of the expansion service, developers are free to utilize the service in their own implementations.

Expansion Service Rulesets

Each instance of the expansion service consists of a collection of rulesets. Each ruleset consists of a key value and its associated set of rules. Callers of the expansion service provide a key and a value to be expanded. The expansion service then looks up the set of rules for the specified key. The expansion service cumulatively applies each of the rules in the set, starting with the original value. The result is returned to the caller.

Table 81. Expansion Service Ruleset Format
Key (Attribute)	Rules (original → new)
key1	`value1`	`replacement1`
	value2	`replacement2`
	value3	`replacement3`
key2	`value1`	`replacement1`
key2	value2	`replacement2`

Included Expansions

Note that the rules listed for each key are processed in order, so they may build upon each other, i.e., a new value from the new replacement string may be expanded by a subsequent rule. In the example Location:Goodyear would expand to Goodyear AZ USA and Title:VP-Sales would expand to VP-Sales VP Sales.

To use the expansion service, modify the following two files within the <DDF_HOME>/etc/pdp directory:

<DDF_HOME>/etc/pdp/ddf-metacard-attribute-ruleset.cfg
<DDF_HOME>/etc/pdp/ddf-user-attribute-ruleset.cfg

The examples below use the following collection of rulesets:

Table 82. Expansion Service Example Ruleset
Key (Attribute)	Rules (original → new)
Location	`Goodyear`	`Goodyear AZ`
	AZ	`AZ USA`
	CA	`CA USA`
Title	`VP-Sales`	`VP-Sales VP Sales`
Title	VP-Engineering	`VP-Engineering VP Engineering`

It is expected that multiple instances of the expansion service will be running at the same time. Each instance of the service defines a unique property that is useful for retrieving specific instances of the expansion service. There are two pre-defined instances used by DDF: one for expanding user attributes and one for metacard attributes.

Property Name Value Description

mapping

security.user.attribute.mapping

This instance is configured with rules that expand the user’s attribute values for security checking.

mapping

security.metacard.attribute.mapping

This instance is configured with rules that expand the metacard’s security attributes before comparing with the user’s attributes.

Expansion Service Configuration Files

Additional instance of the expansion service can be configured using a configuration file. The configuration file can have three different types of lines:

comments: any line prefixed with the # character is ignored as a comment (for readability, blank lines are also ignored)
attribute separator: a line starting with separator= defines the attribute separator string.
rule: all other lines are assumed to be rules defined in a string format <key>:<original value>:<new value>

The following configuration file defines the rules shown above in the example table (using the space as a separator):

Sample Expansion Configuration File

# This defines the separator that will be used when the expansion string contains multiple
# values - each will be separated by this string. The expanded string will be split at the
# separator string and each resulting attribute added to the attribute set (duplicates are
# suppressed). No value indicates the default value of ' ' (space).
separator=

# The following rules define the attribute expansion to be performed. The rules are of the
# form:
#       <attribute name>:<original value>:<expanded value>
# The rules are ordered, so replacements from the first rules may be found in the original
# values of subsequent rules.
Location:Goodyear:Goodyear AZ
Location:AZ:AZ USA
Location:CA:CA USA
Title:VP-Sales:VP-Sales VP Sales
Title:VP-Engineering:VP-Engineering VP Engineering

Expansion Commands

DDF includes commands to work with the Expansion service.

25.11. Security Token Service

The Security Token Service (STS) is a service running in DDF that generates SAML v2.0 assertions. These assertions are then used to authenticate a client allowing them to issue other requests, such as ingests or queries to DDF services.

The STS is an extension of Apache CXF-STS. It is a SOAP web service that utilizes WS-Trust. The generated SAML assertions contain attributes about a user and is used by the Policy Enforcement Point (PEP) in the secure endpoints. Specific configuration details on the bundles that come with DDF can be found on the Security STS application page. This page details all of the STS components that come out of the box with DDF, along with configuration options, installation help, and which services they import and export.

The STS server contains validators, claim handlers, and token issuers to process incoming requests. When a request is received, the validators first ensure that it is valid. The validators verify authentication against configured services, such as LDAP, DIAS, PKI. If the request is found to be invalid, the process ends and an error is returned. Next, the claims handlers determine how to handle the request, adding user attributes or properties as configured. The token issuer creates a SAML 2.0 assertion and associates it with the subject. The STS server sends an assertion back to the requestor, which is used to authenticate and authorize subsequent SOAP and REST requests.

The STS can be used to generate SAML v2.0 assertions via a SOAP web service request. Out of the box, the STS supports authentication from existing SAML tokens, username/password, and x509 certificates. It also supports retrieving claims using LDAP and properties files.

25.11.1. STS Claims Handlers

Claims handlers are classes that convert the incoming user credentials into a set of attribute claims that will be populated in the SAML assertion. An example in action would be the LDAPClaimsHandler that takes in the user’s credentials and retrieves the user’s attributes from a backend LDAP server. These attributes are then mapped and added to the SAML assertion being created. Integrators and developers can add more claims handlers that can handle other types of external services that store user attributes.

25.11.2. Security STS

The Security STS application contains the bundles and services necessary to run and talk to a Security Token Service (STS). It builds off of the Apache CXF STS code and adds components specific to DDF functionality.

Table 84. Security STS Components
Bundle Name	Located in Feature	Description/Link to Bundle Page
`security-sts-realm`	`security-sts-realm`	Security STS Realm
`security-sts-ldaplogin`	`security-sts-ldaplogin`	Security STS LDAP Login
`security-sts-ldapclaimshandler`	`security-sts-ldapclaimshandler`	Security STS LDAP Claims Handler
`security-sts-server`	`security-sts-server`	Security STS Server
`security-sts-samlvalidator`	`security-sts-server`	Contains the default CXF SAML validator and exposes it as a service for the STS.
`security-sts-x509validator`	`security-sts-server`	Contains the default CXF x509 validator and exposes it as a service for the STS.

25.11.3. Security STS Client Config

The Security STS Client Config bundle keeps track and exposes configurations and settings for the CXF STS client. This client can be used by other services to create their own STS client. Once a service is registered as a watcher of the configuration, it will be updated whenever the settings change for the sts client.

25.11.3.1. Installing the Security STS Client Config

This bundle is installed by default.

25.11.3.2. Configuring the Security STS Client Config

Configure the Security STS Client Config from the Admin Console:

Navigate to the Admin Console.
Select Security Application.
Select Configuration tab.
Select Security STS Client.

See Security STS Client configurations for all possible configurations.

25.11.4. External/WS-S STS Support

This configuration works just like the STS Client Config for the internal STS, but produces standard requests instead of the custom DDF ones. It supports two new auth types for the context policy manager, WSSBASIC and WSSPKI. Use these auth types when connecting to a non-DDF STS or if ignoring realms.

25.11.4.1. Security STS Address Provider

This allows one to select which STS address will be used (e.g. in SOAP sources) for clients of this service. Default is off (internal).

25.11.5. Security STS LDAP Login

The Security STS LDAP Login bundle enables functionality within the STS that allows it to use an LDAP to perform authentication when passed a UsernameToken in a RequestSecurityToken SOAP request.

25.11.5.1. Installing the Security STS LDAP Login

This bundle is not installed by default but can be added by installing the security-sts-ldaplogin feature.

25.11.5.2. Configuring the Security STS LDAP Login

Configure the Security STS LDAP Login from the Admin Console:

Navigate to the Admin Console.
Select Security Application.
Select Configuration tab
Select Security STS LDAP Login.

Table 85. Security STS LDAP Login Settings
Configuration Name	Default Value	Additional Information
LDAP URL	`ldaps://${org.codice.ddf.system.hostname}:1636`
StartTLS	`false`	Ignored if the URL uses ldaps.

LDAP Base User DN	`ou=users,dc=example,dc=com`
LDAP Base Group DN	`ou=groups,dc=example,dc=com`

25.11.6. Security STS LDAP Claims Handler

The Security STS LDAP Claims Handler bundle adds functionality to the STS server that allows it to retrieve claims from an LDAP server. It also adds mappings for the LDAP attributes to the STS SAML claims.

Note	All claims handlers are queried for user attributes regardless of realm. This means that two different users with the same username in different LDAP servers will end up with both of their claims in each of their individual assertions.

25.11.6.1. Installing Security STS LDAP Claims Handler

This bundle is not installed by default and can be added by installing the security-sts-ldapclaimshandler feature.

25.11.6.2. Configuring the Security STS LDAP Claims Handler

Configure the Security STS LDAP Claims Handler from the Admin Console:

Navigate to the Admin Console.
Select Security Application
Select Configuration tab.

25.11.7. Security STS Server

The Security STS Server is a bundle that starts up an implementation of the CXF STS. The STS obtains many of its configurations (Claims Handlers, Token Validators, etc.) from the OSGi service registry as those items are registered as services using the CXF interfaces. The various services that the STS Server imports are listed in the Implementation Details section of this page.

Note	The WSDL for the STS is located at the `security-sts-server/src/main/resources/META-INF/sts/wsdl/ws-trust-1.4-service.wsdl` within the source code.

25.11.7.1. Installing the Security STS Server

This bundle is installed by default and is required for DDF to operate.

25.11.7.2. Configuring the Security STS Server

Configure the Security STS Server from the Admin Console:

Navigate to the Admin Console.
Select Security Application
Select Configuration tab.
Select Security STS Server.

Table 89. Security STS Server Settings
Configuration Name	Default Value	Additional Information
SAML Assertion Lifetime	`1800`
Token Issuer	`https://${org.codice.ddf.system.hostname}:${org.codice.ddf.system.httpsPort}${org.codice.ddf.system.rootContext}/idp/login`	The name of the server issuing tokens. Generally this is unique identifier of this IdP.
Signature Username	`localhost`	Alias of the private key in the STS Server’s keystore used to sign messages.
Encryption Username	`localhost`	Alias of the private key in the STS Server’s keystore used to encrypt messages.

25.11.8. Security STS Service

The Security STS Service performs authentication of a user by delegating the authentication request to an STS. This is different than the services located within the Security PDP application as those ones only perform authorization and not authentication.

25.11.8.1. Installing the Security STS Realm

This bundle is installed by default and should not be uninstalled.

25.11.8.2. Configuring the Security STS Realm

The Security STS Realm has no configurable properties.

Table 91. Security STS Realm Exported Services
Registered Interfaces	Implementation Class	Properties Set
`org.apache.shiro.realm.Realm`	`ddf.security.realm.sts.StsRealm`	None

25.12. Federated Identity

Each instance of DDF may be configured with its own security policy that determines the resources a user may access and the actions they may perform. To decide whether a given request is permitted, DDF references the SAML assertion stored internally in the requestor’s Subject. This assertion is generated by the STS during authentication and contains a collection of attributes that identify the requestor. Based on these attributes and the configured policy, DDF makes an authorization decision. See Security PDP for more information.

This authorization process works when the requestor authenticates directly with DDF as they are guaranteed to have a Subject. However, when federating, DDF proxies requests to federated Sources and this poses a problem. The requestor doesn’t authenticate with federated Sources, but Sources still need to make authorization decisions.

To solve this problem, DDF uses federated identity. When performing any federated request (query, resource retrival, etc), DDF attaches the requestor’s SAML assertion to the outgoing request. The federated Source extracts the assertion and validates its signature to make sure it was generated by a trusted entity. If so, the federated Source will construct a Subject for the requestor and perform the request using that Subject. The Source can then make authorization decisions using the process already described.

How DDF attaches SAML assertions to federated requests depends on the endpoint used to connect to a federated Source. When using a REST endpoint such as CSW, DDF places the assertion in the HTTP Authorization header. When using a SOAP endpoint, it places the assertion in the SOAP security header.

The figure below shows a federated query between two instances of DDF that support federated identity.

A user submits a search to DDF.
DDF generates a catalog request, attaches the user’s Subject, and sends the request to the Catalog Framework.
The Catalog Framework extracts the SAML assertion from the Subject and sends an HTTP request to each federated Source with the assertion attached.
A federated Source receives this request and extracts the SAML assertion. The federated Source then validates the authenticity of the SAML Assertion. If the assertion is valid, the federated Source generates a Subject from the assertion to represent the user who initiated the request.
The federated Source filters all results that the user is not authorized to view and returns the rest to DDF.
DDF takes the results from all Sources, filters those that the user is not authorized to view and returns the remaining results to the user.

Note	With federated identity, results are filtered both by the federated Source and client DDF. This is important as each may have different authorization policies.

Warning

Support for federated identity was added in DDF 2.8.x. Federated Sources older than this will not perform any filtering. Instead, they will return all available results and leave filtering up to the client.

26. Developing DDF Components

Create custom implementations of DDF components.

26.1. Developing Complementary Catalog Frameworks

DDF and the underlying OSGi technology can serve as a robust infrastructure for developing frameworks that complement the Catalog.

26.1.1. Simple Catalog API Implementations

The Catalog API implementations, which are denoted with the suffix of Impl on the Java file names, have multiple purposes and uses:

First, they provide a good starting point for other developers to extend functionality in the framework. For instance, extending the MetacardImpl allows developers to focus less on the inner workings of DDF and more on the developer’s intended purposes and objectives.
Second, the Catalog API Implementations display the proper usage of an interface and an interface’s intentions. Also, they are good code examples for future implementations. If a developer does not want to extend the simple implementations, the developer can at least have a working code reference on which to base future development.

26.1.2. Use of the Whiteboard Design Pattern

The Catalog makes extensive use of the Whiteboard Design Pattern. Catalog Components are registered as services in the OSGi Service Registry, and the Catalog Framework or any other clients tracking the OSGi Service Registry are automatically notified by the OSGi Framework of additions and removals of relevant services.

The Whiteboard Design Pattern is a common OSGi technique that is derived from a technical whitepaper provided by the OSGi Alliance in 2004. It is recommended to use the Whiteboard pattern over the Listener pattern in OSGi because it provides less complexity in code (both on the client and server sides), fewer deadlock possibilities than the Listener pattern, and closely models the intended usage of the OSGi framework.

26.1.3. Recommendations for Framework Development

Provide extensibility similar to that of the Catalog.
- Provide a stable API with interfaces and simple implementations (refer to http://www.ibm.com/developerworks/websphere/techjournal/1007_charters/1007_charters.html).
Make use of the Catalog wherever possible to store, search, and transform information.
Utilize OSGi standards wherever possible.
- ConfigurationAdmin
- MetaType
Utilize the sub-frameworks available in DDF.
- Karaf
- CXF
- PAX Web and Jetty

26.1.4. Catalog Framework Reference

The Catalog Framework can be requested from the OSGi Service Registry.

Blueprint Service Reference

<reference id="catalogFramework" interface="DDF.catalog.CatalogFramework" />

26.1.4.1. Methods

The CatalogFramework provides convenient methods to transform Metacards and QueryResponses using a reference to the CatalogFramework.

26.1.4.1.1. Create, Update, and Delete Methods

Create, Update, and Delete (CUD) methods add, change, or remove stored metadata in the local Catalog Provider.

Example Create, Update, Delete Methods


  1
2
3

  public CreateResponse create(CreateRequest createRequest) throws IngestException, SourceUnavailableException;
public UpdateResponse update(UpdateRequest updateRequest) throws IngestException, SourceUnavailableException;
public DeleteResponse delete(DeleteRequest deleteRequest) throws IngestException, SourceUnavailableException;

CUD operations process PolicyPlugin, AccessPlugin, and PreIngestPlugin instances before execution and PostIngestPlugin instances after execution.

26.1.4.1.2. Query Methods

Query methods search metadata from available Sources based on the QueryRequest properties and Federation Strategy. Sources could include Catalog Provider, Connected Sources, and Federated Sources.

Example Query Methods


  1
2

  public QueryResponse query(QueryRequest query) throws UnsupportedQueryException,SourceUnavailableException, FederationException;
public QueryResponse query(QueryRequest queryRequest, FederationStrategy strategy) throws SourceUnavailableException, UnsupportedQueryException, FederationException;

Query requests process PolicyPlugin, AccessPlugin, and PreQueryPlugin instances before execution and PolicyPlugin, AccessPlugin, and PostQueryPlugin instances after execution.

26.1.4.1.3. Resource Methods

Resource methods retrieve products from Sources.

Example Resource Methods


  1
2
3

  public ResourceResponse getEnterpriseResource(ResourceRequest request) throwsIOException, ResourceNotFoundException, ResourceNotSupportedException;
public ResourceResponse getLocalResource(ResourceRequest request) throws IOException, ResourceNotFoundException, ResourceNotSupportedException;
public ResourceResponse getResource(ResourceRequest request, String resourceSiteName) throws IOException, ResourceNotFoundException, ResourceNotSupportedException;

Resource requests process `PreResourcePlugin`s before execution and `PostResourcePlugin`s after execution.

26.1.4.1.4. Source Methods

Source methods can get a list of Source identifiers or request descriptions about Sources.

Example Source Methods


  1
2

  public Set<String> getSourceIds();
public SourceInfoResponse getSourceInfo(SourceInfoRequest sourceInfoRequest) throws SourceUnavailableException;

26.1.4.1.5. Transform Methods

Transform methods provide convenience methods for using Metacard Transformers and Query Response Transformers.

Transform Methods

  // Metacard Transformer
public BinaryContent transform(Metacard metacard, String transformerId, Map<String,Serializable> requestProperties) throws CatalogTransformerException;

 // Other implementation details ...

private void convert(QueryResponse queryResponse ) {
    // ...
    String transformerId = "rss";

    BinaryContent content = catalogFramework.transform(queryResponse, transformerId, null);

    // ...

}

26.1.4.3. Dependency Injection

Using Blueprint or another injection framework, transformers can be injected from the OSGi Service Registry.

Blueprint Service Reference

<reference id="[[Reference Id" interface="DDF.catalog.transform.[[Transformer Interface Name]]" filter="(shortname=[[Transformer Identifier]])" />

Each transformer has one or more transform methods that can be used to get the desired output.

Input Transformer Example


  1

3

  DDF.catalog.transform.InputTransformer inputTransformer = retrieveInjectedInstance() ;

Metacard entry = inputTransformer.transform(messageInputStream);

Metacard Transformer Example


  1

  DDF.catalog.transform.MetacardTransformer metacardTransformer = retrieveInjectedInstance() ;

BinaryContent content = metacardTransformer.transform(metacard, arguments);

Query Response Transformer Example

3

  DDF.catalog.transform.QueryResponseTransformer queryResponseTransformer = retrieveInjectedInstance() ;

BinaryContent content = queryResponseTransformer.transform(sourceSesponse, arguments);

26.1.4.4. OSGi Service Registry

Important

In the vast majority of cases, working with the OSGi Service Reference directly should be avoided. Instead, dependencies should be injected via a dependency injection framework like Blueprint.

Transformers are registered with the OSGi Service Registry. Using a BundleContext and a filter, references to a registered service can be retrieved.

OSGi Service Registry Reference Example


  1
2
3
4

  ServiceReference[] refs =
    bundleContext.getServiceReferences(DDF.catalog.transform.InputTransformer.class.getName(),"(shortname=" + transformerId + ")");
InputTransformer inputTransformer = (InputTransformer) context.getService(refs[0]);
Metacard entry = inputTransformer.transform(messageInputStream);

26.2. Developing Metacard Types

Create custome Metacard types with Metacard Type definition files.

26.2.1. Metacard Type Definition File

To define Metacard Types, the definition file must have a metacardTypes key in the root object.

{
    "metacardTypes": [...]
}

The value of metacardTypes must be an array of Metacard Type Objects, which are composed of the type (required), extendsTypes (optional), and attributes (optional) keys.

Sample Top Level metacardTypes Definition

{
    "metacardTypes": [
        {
            "type": "my-metacard-type",
            "extendsTypes": ["core", "security"],
            "attributes": {...}
        }
    ]
}

The value of the type key is the name of the metacard type being defined. This field is required.

The value of the extendsTypes key is an array of metacard type names (strings) whose attributes you wish to include in your type. Valid Metacard Types already defined in the system or any Metacard Types already defined in this file will work. Please note this section is evaluated from top to bottom so order any types used in other definitions above where they are used in the extendsTypes of other definitions. This key and value may be completely omitted to not extend any types.

The value of the attributes key is a map where each key is the name of an attribute type to include in this metacard type and each value is a map with a single key named required and a boolean value. Required attributes are used for metacard validation - metacards that lack required attributes will be flagged with validation errors. attributes may be completely omitted. required may be omitted.

Sample Complete metacardTypes Definition

{
    "metacardTypes": [
        {
            "type": "my-metacard-type",
            "attributes": {
                "resolution": {
                    "required": true
                },
                "target-areas": {
                    "required": false
                },
                "expiration": {},
                "point-of-contact": {
                    "required": true
                }
            }
        }
    ]
}

Note	The DDF basic metacard attribute types are added to custom metacard types by default. If any attribute types are required by a metacard type, just include them in the `attributes` map and set `required` to `true`, as shown in the above example with `point-of-contact`.

Multiple Metacard Types in a Single File

{
    "metacardTypes": [
        {
            "type": "my-metacard-type",
            "attributes": {
                "resolution": {
                    "required": true
                },
                "target-areas": {
                    "required": false
                }
            }
        },
        {
            "type": "another-metacard-type",
            "attributes": {
                "effective": {
                    "required": true
                },
                "resolution": {
                    "required": false
                }
            }
        }
    ]
}

26.3. Developing Global Attribute Validators

26.3.1. Global Attribute Validators File

To define Validators, the definition file must have a validators key in the root object.

{
    "validators": {...}
}

The value of validators is a map of the attribute name to a list of validators for that attribute.

{
    "validators": {
        "point-of-contact": [...]
    }
}

Each object in the list of validators is the validator name and list of arguments for that validator.

{
    "validators": {
        "point-of-contact": [
            {
                "validator": "pattern",
                "arguments": [".*regex.+\\s"]
            }
        ]
    }
}

Warning

The value of the arguments key must always be an array of strings, even for numeric arguments, e.g. ["1", "10"]

The validator key must have a value of one of the following:

2. validator Possible Values

size (validates the size of Strings, Arrays, Collections, and Maps)
- arguments: (2) [integer: lower bound (inclusive), integer: upper bound (inclusive)]
  - lower bound must be greater than or equal to zero and the upper bound must be greater than or equal to the lower bound
pattern
- arguments: (1) [regular expression]
pastdate
- arguments: (0) [NO ARGUMENTS]
futuredate
- arguments: (0) [NO ARGUMENTS]
range
- (2) [number (decimal or integer): inclusive lower bound, number (decimal or integer): inclusive upper bound]
  - uses a default epsilon of 1E-6 on either side of the range to account for floating point representation inaccuracies
- (3) [number (decimal or integer): inclusive lower bound, number (decimal or integer): inclusive upper bound, decimal number: epsilon (the maximum tolerable error on either side of the range)]
enumeration
- arguments: (unlimited) [list of strings: each argument is one case-sensitive, valid enumeration value]

- arguments: (4+) [attribute value or null, one of mustHave|cannotHave|canOnlyHave, target attribute name, null or target attribute value(s) as additional arguments]
match_any
- validators: (unlimited) [list of previously defined validators: valid if any validator succeeds]

                        "validator": "range",
                        "arguments": ["1", "25"]
                    },
                    {
                        "validator": "enumeration",
                        "arguments": ["Collection", "Dataset", "Event"]
                    }

             }
         ]
    }
}

26.4. Developing Attribute Types

Create custom attribute types with Attribute Type definition files.

26.4.1. Attribute Type Definition File

To define Attribute Types, the definition file must have an attributeTypes key in the root object.

{
    "attributeTypes": {...}
}

The value of attributeTypes must be a map where each key is the attribute type’s name and each value is a map that includes the data type and whether the attribute type is stored, indexed, tokenized, or multi-valued.

Attribute Types

{
    "attributeTypes": {
        "temperature": {
            "type": "DOUBLE_TYPE",
            "stored": true,
            "indexed": true,
            "tokenized": false,
            "multivalued": false
        }
    }
}

The attributes stored, indexed, tokenized, and multivalued must be included and must have a boolean value.

3. Required Attribute Definitions

stored: If true, the value of the attribute should be stored in the underlying datastore. Some attributes may only be indexed or used in transit and do not need to be persisted.
indexed: If true, then the value of the attribute should be included in the datastore’s index and therefore be part of query evaluation.
tokenized: Only applicable to STRING_TYPE attributes, if true then stopwords and punctuation will be stripped prior to storing and/or indexing. If false, only an exact string will match.
multi-valued: If true, then the attribute values will be Lists of the attribute type rather than single values.

The type attribute must also be included and must have one of the allowed values:

4. type Attribute Possible Values

DATE_TYPE
STRING_TYPE
XML_TYPE
LONG_TYPE
BINARY_TYPE
GEO_TYPE
BOOLEAN_TYPE
DOUBLE_TYPE
FLOAT_TYPE
INTEGER_TYPE
OBJECT_TYPE
SHORT_TYPE

An example with multiple attributes defined:

Multiple Attributes Defined

{
    "attributeTypes": {
        "resolution": {
            "type": "STRING_TYPE",
            "stored": true,
            "indexed": true,
            "tokenized": false,
            "multivalued": false
        },
        "target-areas": {
            "type": "GEO_TYPE",
            "stored": true,
            "indexed": true,
            "tokenized": false,
            "multivalued": true
        }
    }
}

26.5. Developing Default Attribute Types

Create custom default attribute types.

26.5.1. Default Attribute Values

To define default attribute values, the definition file must have a defaults key in the root object.

{
    "defaults": [...]
}

The value of defaults is a list of objects where each object contains the keys attribute, value, and optionally metacardTypes.

{
    "defaults": [
        {
            "attribute": ...,
            "value": ...,
            "metacardTypes": [...]
        }
    ]
}

The value corresponding to the attribute key is the name of the attribute to which the default value will be applied. The value corresponding to the value key is the default value of the attribute.

Note	The attribute’s default value must be of the same type as the attribute, but it has to be written as a string (i.e., enclosed in quotation marks) in the JSON file. Dates must be UTC datetimes in the ISO 8601 format, i.e., `yyyy-MM-ddTHH:mm:ssZ`

The metacardTypes key is optional. If it is left out, then the default attribute value will be applied to every metacard that has that attribute. It can be thought of as a 'global' default value. If the metacardTypes key is included, then its value must be a list of strings where each string is the name of a metacard type. In this case, the default attribute value will be applied only to metacards that match one of the types given in the list.

Note	In the event that an attribute has a 'global' default value as well as a default value for a specific metacard type, the default value for the specific metacard type will be applied (i.e., the more specific default value wins).

Example:

{
    "defaults": [
        {
            "attribute": "title",
            "value": "Default Title"
        },
        {
            "attribute": "description",
            "value": "Default video description",
            "metacardTypes": ["video"]
        },
        {
            "attribute": "expiration",
            "value": "2020-05-06T12:00:00Z",
            "metacardTypes": ["video", "nitf"]
        },
        {
            "attribute": "frame-rate",
            "value": "30"
        }
    ]
}

26.6. Developing Attribute Injections

Attribute injections are defined attributes that will be injected into all metacard types or into specific metacard types. This capability allows metacard types to be extended with new attributes.

26.6.1. Attribute Injection Definition

To define attribute injections, create a JSON file in the <DDF_HOME>/etc/definitions directory. The definition file must have an inject key in the root object.

Inject Key

{
  "inject": [...]
}

The value of inject is simply a list of objects where each object contains the key attribute and optionally metacardTypes.

Inject Values

{
  "inject": [
    {
      "attribute": ...,
      "metacardTypes": [...]
    }
  ]
}

The value corresponding to the attribute key is the name of the attribute to inject.

The metacardTypes key is optional. If it is left out, then the attribute will be injected into every metacard type. In that case it can be thought of as a 'global' attribute injection. If the metacardTypes key is included, then its value must be a list of strings where each string is the name of a metacard type. In this case, the attribute will be injected only into metacard types that match one of the types given in the list.

Global and Specific Inject Values

{
  "inject": [
    // Global attribute injection, all metacards
    {
      "attribute": "rating"
    },
    // Specific attribute injection, only "video" metacards
    {
      "attribute": "cloud-cover",
      "metacardTypes": "video"
    }
  ]
}

Note	Attributes must be registered in the attribute registry (see the `AttributeRegistry` interface) to be injected into metacard types. For example, attributes defined in JSON definition files are placed in the registry, so they can be injected.

Add a second key for attributeTypes to register the new types defined previously. For each attribute injections, specify the name and properties for that attribute.

type: Data type of the possible values for this attribute.
indexed: Boolean, attribute is indexed.
stored: Boolean, attribute is stored.
tokenized: Boolean, attribute is stored.
multivalued: Boolean, attribute can hold multiple values.

      "indexed": true,
      "stored": true,
      "tokenized": true,
      "multivalued": false
    }
  }
}

26.7. Developing Endpoints

Custom endpoints can be created, if necessary. See Endpoints for descriptions of provided endpoints.

Complete the following procedure to create an endpoint.

Create a Java class that implements the endpoint’s business logic. Example: Creating a web service that external clients can invoke.
Add the endpoint’s business logic, invoking CatalogFramework calls as needed.
Import the DDF packages to the bundle’s manifest for run-time (in addition to any other required packages):
Import-Package: ddf.catalog, ddf.catalog.*
Retrieve an instance of CatalogFramework from the OSGi registry. (Refer to OSGi Basics - Service Registry for examples.)
Deploy the packaged service to DDF. (Refer to OSGi Basics - Bundles.)

Note	It is recommended to use the maven bundle plugin to create the Endpoint bundle’s manifest as opposed to directly editing the manifest file.

Tip	No implementation of an interface is required Unlike other DDF components that require you to implement a standard interface, no implementation of an interface is required in order to create an endpoint.

Table 92. Common Endpoint Business Logic
Methods	Use
`Ingest`	Add, modify, and remove metadata using the ingest-related `CatalogFramework` methods: create, update, and delete.
`Query`	Request metadata using the `query` method.
`Source`	Get available `Source` information.
`Resource`	Retrieve products referenced in Metacards from Sources.
`Transform`	Convert common Catalog Framework data types to and from other data formats.

26.8. Developing Input Transformers

DDF supports the creation of custom input transformers for use cases not covered by the included implementations.

Creating a custom input Transformer:

Create a new Java class that implements ddf.catalog.transform.InputTransformer.
public class SampleInputTransformer implements ddf.catalog.transform.InputTransformer
Implement the transform methods.
public Metacard transform(InputStream input) throws IOException, CatalogTransformerException
public Metacard transform(InputStream input, String id) throws IOException, CatalogTransformerException
Import the DDF interface packages to the bundle manifest (in addition to any other required packages).
Import-Package: ddf.catalog,ddf.catalog.transform

Create an OSGi descriptor file to communicate with the OSGi Service Registry (described in the OSGi Basics section). Export the service to the OSGi Registry and declare service properties.

`description`	(Optional) A short, human-readable description that describes the functionality of the service and the output.	`This service converts a single metacard xml document to an atom entry element.`

Deploy OSGi Bundle to OSGi runtime.

26.8.1. Create an XML Input Transformer using SaxEventHandlers

For a transformer to transform XML, (as opposed to JSON or a Word document, for example) there is a simpler solution than fully implementing a MetacardValidator. DDF includes an extensible, configurable XmlInputTransformer. This transformer can be instantiated via blueprint as a managed service factory and configured via metatype. The XmlInputTransformer takes a configuration of SaxEventHandlers. A SaxEventHandler is a class that handles SAX Events (a very fast XML parser) to parse metadata and create metacards. Any number of SaxEventHandlers can be implemented and included in the XmlInputTransformer configuration. See the catalog-transformer-streaming-impl bundle for examples (XmlSaxEventHandlerImpl which parses the DDF Metacard XML Metadata and the GmlHandler which parses GML 2.0) Each SaxEventHandler implementation has a SaxEventHandlerFactory associated with it. The SaxEventHandlerFactory is responsible for instantiating new SaxEventHandlers - each transform request gets a new instance of XmlInputTransformer and set of SaxEventHandlers to be thread- and state-safe.

The following diagrams intend to clarify implementation details:

The XmlInputTransformer Configuration diagram shows the XmlInputTransformer configuration, which is configured using the metatype and has the SaxEventHandlerFactory ids. Then, when a transform request is received, the ManagedServiceFactory instantiates a new XmlInputTransformer. This XmlInputTransformer then instantiates a new SaxEventHandlerDelegate with the configured SaxEventHandlersFactory ids. The factories all in turn instantiate a SaxEventHandler. Then, the SaxEventHandlerDelegate begins parsing the XML input document, handing the SAX Events off to each SaxEventHandler, which handle them if they can. After parsing is finished, each SaxEventHandler returns a list of Attributes to the SaxEventHandlerDelegate and XmlInputTransformer which add the attributes to the metacard and then return the fully constructed metacard.

XMLInputTransformer Configuration

XMLInputTransformer SaxEventHandlerDelegate Configuration

For more specific details, see the Javadoc for the org.codice.ddf.transformer.xml.streaming.* package. Additionally, see the source code for the org.codice.ddf.transformer.xml.streaming.impl.GmlHandler.java, org.codice.ddf.transformer.xml.streaming.impl.GmlHandlerFactory, org.codice.ddf.transformer.xml.streaming.impl.XmlInputTransformerImpl, and org.codice.ddf.transformer.xml.streaming.impl.XmlInputTransformerImplFactory.

Note

The XmlInputTransformer & SaxEventHandlerDelegate create and configure themselves based on String matches of the configuration ids with the SaxEventHandlerFactory ids, so ensure these match.
The XmlInputTransformer uses a DynamicMetacardType. This is pertinent because a metacards attributes are only stored in Solr if they are declared on the MetacardType. Since the DynamicMetacardType is constructed dynamically, attributes are declared by the SaxEventHandlerFactory that parses them, as opposed to the MetacardType. See org.codice.ddf.transformer.xml.streaming.impl.XmlSaxEventHandlerFactoryImpl.java vs ddf.catalog.data.impl.BasicTypes.java

26.8.2. Create an Input Transformer Using Apache Camel

Alternatively, make an Apache Camel route in a blueprint file and deploy it using a feature file or via hot deploy.

26.8.2.1. Input Transformer Design Pattern (Camel)

Follow this design pattern for compatibility:

From

When using from, catalog:inputtransformer?id=text/xml, an Input Transformer will be created and registered in the OSGi registry with an id of text/xml.

When using to, catalog:inputtransformer?id=text/xml, an Input Transformer with an id matching text/xml will be discovered from the OSGi registry and invoked.

Table 94. InputTransformer Message Formats
Exchange Type	Field	`Type`
Request (comes from `<from>` in the route)	body	`java.io.InputStream`
Response (returned after called via `<to>` in the route)	body	`ddf.catalog.data.Metacard`

Tip	Its always a good idea to wrap the `mimeType` value with the RAW parameter as shown in the example above. This will ensure that the value is taken exactly as is, and is especially useful when you are using special characters.

            <from uri="catalog:inputtransformer?mimeType=RAW(id=text/xml;id=vehicle)"/>
            <to uri="xslt:vehicle.xslt" /> <!-- must be on classpath for this bundle -->
            <to uri="catalog:inputtransformer?mimeType=RAW(id=application/json;id=geojson)" />
        </route>
    </camelContext>
</blueprint>

InputTransformer Creation Details

Defines this as an Apache Aries blueprint file.
Defines the Apache Camel context that contains the route.
Defines start of an Apache Camel route.
Defines the endpoint/consumer for the route. In this case it is the DDF custom catalog component that is an InputTransformer registered with an id of text/xml;id=vehicle meaning it can transform an InputStream of vehicle data into a metacard. Note that the specified XSL stylesheet must be on the classpath of the bundle that this blueprint file is packaged in.
Defines the XSLT to be used to transform the vehicle input into GeoJSON format using the Apache Camel provided XSLT component.
Defines the route node that accepts GeoJSON formatted input and transforms it into a Mmtacard, using the DDF custom catalog component that is an InputTransformer registered with an id of application/json;id=geojson.

Note	An example of using an Apache Camel route to define an `InputTransformer` in a blueprint file and deploying it as a bundle to an OSGi container can be found in the DDF SDK examples at `DDF/sdk/sample-transformers/xslt-identity-input-transformer`

26.8.3. Input Transformer Boot Service Flag

The org.codice.ddf.platform.bootflag.BootServiceFlag service with a service property of id=inputTransformerBootFlag is used to indicate certain Input Transformers are ready in the system. Adding an Input Transformers ID to a new or existing JSON file under <DDF_HOME>/etc/transformers will cause the service to wait for an Input Transformer with the given ID.

26.9. Developing Metacard Transformers

In general, a MetacardTransformer is used to transform a Metacard into some desired format useful to the end user or as input to another process. Programmatically, a MetacardTransformer transforms a Metacard into a BinaryContent instance, which translates the Metacard into the desired final format. Metacard transformers can be used through the Catalog Framework transform convenience method or requested from the OSGi Service Registry by endpoints or other bundles.

26.9.1. Creating a New Metacard Transformer

Existing metacard transformers are written as Java classes, and these steps walk through the steps to create a custom metacard transformer.

Create a new Java class that implements ddf.catalog.transform.MetacardTransformer.
public class SampleMetacardTransformer implements ddf.catalog.transform.MetacardTransformer
Implement the transform method.
public BinaryContent transform(Metacard metacard, Map<String, Serializable> arguments) throws CatalogTransformerException
1. transform must return a Metacard or throw an exception. It cannot return null.
Import the DDF interface packages to the bundle manifest (in addition to any other required packages).
Import-Package: ddf.catalog,ddf.catalog.transform

Create an OSGi descriptor file to communicate with the OSGi Service registry (described in the OSGi Basics section). Export the service to the OSGi registry and declare service properties.

26.10. Developing Query Response Transformers

A QueryResponseTransformer is used to transform a List of Results from a SourceResponse. Query Response Transformers can be used through the Catalog transform convenience method or requested from the OSGi Service Registry by endpoints or other bundles.

Create a new Java class that implements ddf.catalog.transform.QueryResponseTransformer.
public class SampleResponseTransformer implements ddf.catalog.transform.QueryResponseTransformer
Implement the transform method.
public BinaryContent transform(SourceResponse upstreamResponse, Map<String, Serializable> arguments) throws CatalogTransformerException
Import the DDF interface packages to the bundle manifest (in addition to any other required packages).
Import-Package: ddf.catalog, ddf.catalog.transform
Create an OSGi descriptor file to communicate with the OSGi Service Registry (described in OSGi Basics). Export the service to the OSGi registry and declare service properties.

Deploy OSGi Bundle to OSGi runtime.

26.11. Developing Sources

Sources are components that enable DDF to talk to back-end services. They let DDF perform query and ingest operations on catalog stores and query operations on federated sources.

Source Architecture

26.11.1. Implement a Source Interface

There are three types of sources that can be created to perform query operations. All of these sources must also be able to return their availability and the list of content types currently stored in their back-end data stores.

Catalog Provider

ddf.catalog.source.CatalogProvider is used to communicate with back-end storage and allows for Query and Create/Update/Delete operations.

Federated Source

ddf.catalog.source.FederatedSource is used to communicate with remote systems and only allows query operations.

Connected Source

ddf.catalog.source.ConnectedSource is similar to a Federated Source with the following exceptions:

Queried on all local queries
`SiteName` is hidden (masked with the DDF sourceId) in query results
`SiteService` does not show this Source’s information separate from DDF’s.

Catalog Store

catalog.store.interface is used to store data.

The procedure for implementing any of the source types follows a similar format:

Create a new class that implements the specified Source interface, the ConfiguredService and the required methods.
Create an OSGi descriptor file to communicate with the OSGi registry. (Refer to OSGi Services.)
1. Import DDF packages.
2. Register source class as service to the OSGi registry.
Deploy to DDF.

Important

The factory-pid property of the metatype must contain one of the following in the name: service, Service, source, Source

Note

Remote sources currently extend the ResourceReader interface. However, a RemoteSource is not treated as a ResourceReader. The getSupportedSchemes() method should never be called on a RemoteSource, thus the suggested implementation for a RemoteSource is to return an empty set. The retrieveResource( … ) and getOptions( … ) methods will be called and MUST be properly implemented by a RemoteSource.

26.11.1.1. Developing Catalog Providers

Create a custom implementation of a catalog provider.

Create a Java class that implements CatalogProvider.
public class TestCatalogProvider implements ddf.catalog.source.CatalogProvider
Implement the required methods from the ddf.catalog.source.CatalogProvider interface.
public CreateResponse create(CreateRequest createRequest) throws IngestException; public UpdateResponset update(UpdateRequest updateRequest) throws IngestException; public DeleteResponse delete(DeleteRequest deleteRequest) throws IngestException;
Import the DDF interface packages to the bundle manifest (in addition to any other required packages).
Import-Package: ddf.catalog, ddf.catalog.source
Export the service to the OSGi registry.

Catalog Provider Blueprint example

<service ref="TestCatalogProvider" interface="ddf.catalog.source.CatalogProvider" />

See the existing Catalog Provider list for examples of Catalog Providers included in DDF.

26.11.1.2. Developing Federated Sources

Create a Java class that implements FederatedSource and ConfiguredService.
public class TestFederatedSource implements ddf.catalog.source.FederatedSource, ddf.catalog.service.ConfiguredService
Implement the required methods of the ddf.catalog.source.FederatedSource and ddf.catalog.service.ConfiguredService interfaces.
Import the DDF interface packages to the bundle manifest (in addition to any other required packages).
Import-Package: ddf.catalog, ddf.catalog.source
Export the service to the OSGi registry.

Federated Source Blueprint example

<service ref="TestFederatedSource" interface="ddf.catalog.source.FederatedSource" />

26.11.1.3. Developing Connected Sources

Create a custom implementation of a connected source.

Create a Java class that implements ConnectedSource and ConfiguredService.
public class TestConnectedSource implements ddf.catalog.source.ConnectedSource, ddf.catalog.service.ConfiguredService
Implement the required methods of the ddf.catalog.source.ConnectedSource and ddf.catalog.service.ConfiguredService interfaces.
Import the DDF interface packages to the bundle manifest (in addition to any other required packages).
Import-Package: ddf.catalog, ddf.catalog.source
Export the service to the OSGi registry.

Connected Source Blueprint example

  <service ref="TestConnectedSource" interface="ddf.catalog.source.ConnectedSource" />

Important

In some Providers that are created, there is a need to make Web Service calls through JAXB clients. It is best to NOT create a JAXB client as a global variable. There may be intermittent failures with the creation of Providers and federated sources when clients are created in this manner. To avoid this issue, create any JAXB within the methods requiring it.

26.11.1.4. Exception Handling

In general, sources should only send information back related to the call, not implementation details.

26.11.1.4.1. Exception Examples

Follow these guidelines for effective exception handling:

Use a "Site XYZ not found" message rather than the full stack trace with the original site not found exception.
If the caller issues a malformed search request, return an error describing the right form, or specifically what was not recognized in the request. Do not return the exception and stack trace where the parsing broke.
If the caller leaves something out, do not return the null pointer exception with a stack trace, rather return a generic exception with the message "xyz was missing."

26.11.1.4.2. External Resources for Developing Sources

Three Rules for Effective Exception Handling .

26.12. Developing Catalog Plugins

Plugins extend the functionality of the Catalog Framework by performing actions at specified times during a transaction. Plugin interfaces are located in the Catalog Core API. By implementing a plugin interface, actions can be performed at the desired time.

The following types of plugins can be created:

Table 97. Plugin Interfaces
Plugin Type	Plugin Interface	Invocation Order
Pre-Authorization	`ddf.catalog.plugin.PreAuthorizationPlugin`	Before any security rules are applied.
Policy	`ddf.catalog.plugin.PolicyPlugin`	After pre-authorization plugins, but before other catalog plugins to establish the policy for requests/responses.
Access	`ddf.catalog.plugin.AccessPlugin`	Directly after any policy plugins
Pre-Ingest	`ddf.catalog.plugin.PreIngestPlugin`	Before the Create/Update/Delete method is sent to the Catalog Provider.
Post-Ingest	`ddf.catalog.plugin.PostIngestPlugin`	After the Create/Update/Delete method is sent to the Catalog Provider.
Pre-Query	`ddf.catalog.plugin.PreQueryPlugin`	Prior to the Query/Read method being sent to the Source.
Post-Query	`ddf.catalog.plugin.PostQueryPlugin`	After results have been retrieved from the query but before they are posted to the Endpoint.
Pre-Federated-Query	`ddf.catalog.plugin.PreFederatedQueryPlugin`	Before a federated query is executed.
Post-Federated-Query	`ddf.catalog.plugin.PostFederatedQueryPlugin`	After a federated query has been executed.
Pre-Resource	`ddf.catalog.plugin.PreResourcePlugin`	Prior to a Resource being retrieved.
Post-Resource	`ddf.catalog.plugin.PostResourcePlugin`	After a Resource is retrieved, but before it is sent to the Endpoint.
Pre-Create Storage	`ddf.catalog.content.plugin.PreCreateStoragePlugin`	Experimental Before an item is created in the content repository.
Post-Create Storage	`ddf.catalog.content.plugin.PostCreateStoragePlugin`	Experimental After an item is created in the content repository.
Pre-Update Storage	`ddf.catalog.content.plugin.PreUpdateStoragePlugin`	Experimental Before an item is updated in the content repository.
Post-Update Storage	`ddf.catalog.content.plugin.PostUpdateStoragePlugin`	Experimental After an item is updated in the content repository.
Pre-Subscription	`ddf.catalog.plugin.PreSubscriptionPlugin`	Prior to a Subscription being created or updated.
Pre-Delivery	`ddf.catalog.plugin.PreDeliveryPlugin`	Prior to the delivery of a Metacard when an event is posted.

26.12.1. Implementing Catalog Plugins

The procedure for implementing any of the plugins follows a similar format:

Create a new class that implements the specified plugin interface.
Implement the required methods.
Create an OSGi descriptor file to communicate with the OSGi registry.
1. Register the plugin class as a service to OSGi registry.
Deploy to DDF.

Note	Plugin Performance Concerns Plugins should include a check to determine if requests are local or not. It is usually preferable to take no action on non-local requests.

Tip	Refer to the Javadoc for more information on all Requests and Responses in the `ddf.catalog.operation` and `ddf.catalog.event` packages.

26.12.1.1. Catalog Plugin Failure Behavior

In the event that this Catalog Plugin cannot operate but does not wish to fail the transaction, a PluginExecutionException should be thrown. If processing is to be explicitly stopped, a StopProcessingException should be thrown. For any other exceptions, the Catalog should "fail fast" and cancel the Operation.

26.12.1.2. Implementing Pre-Ingest Plugins

26.13. Developing Token Validators

Token validators are used by the Security Token Service (STS) to validate incoming token requests. The TokenValidator CXF interface must be implemented by all custom token validators. The canHandleToken and validateToken methods must be overridden. The canHandleToken method should return true or false based on the ValueType value of the token that the validator is associated with. The validator may be able to handle any number of different tokens that you specify. The validateToken method returns a TokenValidatorResponse object that contains the Principal of the identity being validated and also validates the ReceivedToken object collected from the RST (RequestSecurityToken) message.

26.14. Developing STS Claims Handlers

Develop a custom claims handler to retrieve attributes from an external attribute store.

A claim is an additional piece of data about a subject that can be included in a token along with basic token data. A claims manager provides hooks for a developer to plug in claims handlers to ensure that the STS includes the specified claims in the issued token.

The following steps define the procedure for adding a custom claims handler to the STS.

The new claims handler must implement the org.apache.cxf.sts.claims.ClaimsHander interface.

Deploy the bundle.

If the new claims handler is hitting an external service that is secured with SSL/TLS, a developer may need to add the root CA of the external site to the DDF trustStore and add a valid certificate into the DDF keyStore. For more information on certificates, refer to Configuring a Java Keystore for Secure Communications.

26.14.1. Example Requests and Responses for SAML Assertions

A client performs a RequestSecurityToken operation against the STS to receive a SAML assertion. The DDF STS offers several different ways to request a SAML assertion. For help in understanding the various request and response formats, samples have been provided. The samples are divided out into different request token types.

26.14.2. BinarySecurityToken (CAS) SAML Security Token Samples

Most endpoints in DDF require the X.509 PublicKey SAML assertion.

To obtain a SAML assertion to use in secure communication to DDF, a RequestSecurityToken (RST) request has to be made to the STS.

A Bearer SAML assertion is automatically trusted by the endpoint. The client doesn’t have to prove it can own that SAML assertion. It is the simplest way to request a SAML assertion, but many endpoints won’t accept a KeyType of Bearer.

26.14.3. UsernameToken Bearer SAML Security Token Sample

WS-Addressing header with Action, To, and Message ID
Valid, non-expired timestamp
Username Token containing a username and password that the STS will authenticate
Issued over HTTPS
KeyType of http://docs.oasis-open.org/ws-sx/ws-trust/200512/Bearer
Claims (optional): Some endpoints may require that the SAML assertion include attributes of the user, such as an authenticated user’s role, name identifier, email address, etc. If the SAML assertion needs those attributes, the RequestSecurityToken must specify which ones to include.

This is the response from the STS containing the SAML assertion to be used in subsequent requests to QCRUD endpoints:

The saml2:Assertion block contains the entire SAML assertion.

The Signature block contains a signature from the STS’s private key. The endpoint receiving the SAML assertion will verify that it trusts the signer and ensure that the message wasn’t tampered with.

The AttributeStatement block contains all the Claims requested.

The Lifetime block indicates the valid time interval in which the SAML assertion can be used.

In order to obtain a SAML assertion to use in secure communication to DDF, a RequestSecurityToken (RST) request has to be made to the STS.

An endpoint’s policy will specify the type of security token needed. Most of the endpoints that have been used with DDF require a SAML v2.0 assertion with a required KeyType of http://docs.oasis-open.org/ws-sx/ws-trust/200512/PublicKey. This means that the SAML assertion provided by the client to a DDF endpoint must contain a SubjectConfirmation block with a type of "holder-of-key" containing the client’s public key. This is used to prove that the client can possess the SAML assertion returned by the STS.

26.14.4. X.509 PublicKey SAML Security Token Sample

The STS that comes with DDF requires the following to be in the RequestSecurityToken request in order to issue a valid SAML assertion. See the request block below for an example of how these components should be populated.

WS-Addressing header containing Action, To, and MessageID blocks
Valid, non-expired timestamp
Issued over HTTPS
TokenType of http://docs.oasis-open.org/wss/oasis-wss-saml-token-profile-1.1#SAMLV2.0
KeyType of http://docs.oasis-open.org/ws-sx/ws-trust/200512/PublicKey
X509 Certificate as the Proof of Possession or POP. This needs to be the certificate of the client that will be both requesting the SAML assertion and using the SAML assertion to issue a query
Claims (optional): Some endpoints may require that the SAML assertion include attributes of the user, such as an authenticated user’s role, name identifier, email address, etc. If the SAML assertion needs those attributes, the RequestSecurityToken must specify which ones to include.
- UsernameToken: If Claims are required, the RequestSecurityToken security header must contain a UsernameToken element with a username and password.

26.14.5. X.509 PublicKey SAML Security Token Sample

This is the response from the STS containing the SAML assertion to be used in subsequent requests to QCRUD endpoints.

The saml2:Assertion block contains the entire SAML assertion.

The SubjectConfirmation block contains the client’s public key, so the server can verify that the client has permission to hold this SAML assertion. The AttributeStatement block contains all of the claims requested.

26.15. Developing Registry Clients

Registry Clients create Federated Sources using the OSGi Configuration Admin. Developers should reference an individual Source’s (Federated, Connected, or Catalog Provider) documentation for the Configuration properties (such as a Factory PID, addresses, intervals, etc) necessary to establish that `Source in the framework.

Creating a Source Configuration

  org.osgi.service.cm.ConfigurationAdmin configurationAdmin = getConfigurationAdmin() ;
org.osgi.service.cm.Configuration currentConfiguration = configurationAdmin.createFactoryConfiguration(getFactoryPid(), null);
Dictionary properties = new Dictionary() ;
properties.put(QUERY_ADDRESS_PROPERTY,queryAddress);
currentConfiguration.update( properties );

Note that the QUERY_ADDRESS_PROPERTY is specific to this Configuration and might not be required for every Source. The properties necessary for creating a Configuration are different for every Source.

26.16. Developing Resource Readers

A ResourceReader is a class that retrieves a resource or product from a native/external source and returns it to DDF. A simple example is that of a File ResourceReader. It takes a file from the local file system and passes it back to DDF. New implementations can be created in order to support obtaining Resources from various Resource data stores.

26.16.1. Creating a New `ResourceReader`

Complete the following procedure to create a ResourceReader.

Create a Java class that implements the DDF.catalog.resource.ResourceReader interface.
Deploy the OSGi bundled packaged service to the DDF run-time.

26.16.1.1. Implementing the `ResourceReader` Interface


  1

  public class TestResourceReader implements DDF.catalog.resource.ResourceReader

ResourceReader has a couple of key methods where most of the work is performed.

Note	URI It is recommended to become familiar with the Java API URI class in order to properly build a `ResourceReader`. Furthermore, a URI should be used according to its specification .

26.16.1.2. retrieveResource


  1

  public ResourceResponse retrieveResource( URI uri, Map<String, Serializable> arguments )throws IOException, ResourceNotFoundException, ResourceNotSupportedException;

This method is the main entry to the ResourceReader. It is used to retrieve a Resource and send it back to the caller (generally the CatalogFramework). Information needed to obtain the entry is contained in the URI reference. The URI Scheme will need to match a scheme specified in the getSupportedSchemes method. This is how the CatalogFramework determines which ResourceReader implementation to use. If there are multiple ResourceReaders supporting the same scheme, these ResourceReaders will be invoked iteratively. Invocation of the ResourceReaders stops once one of them returns a Resource.

Arguments are also passed in. These can be used by the ResourceReader to perform additional operations on the resource.

The URLResourceReader is an example ResourceReader that reads a file from a URI.

Note	The `Map<String, Serializable> arguments` parameter is passed in to support any options or additional information associated with retrieving the resource.

26.16.1.3. Implement `retrieveResource()`

Define supported schemes (e.g., file, http, etc.).
Check if the incoming URI matches a supported scheme. If it does not, throw ResourceNotSupportedException.

Example:


  1
2
3
4

  if ( !uri.getScheme().equals("http") )
 {
   throw new ResourceNotSupportedException("Unsupported scheme received, was expecting http")
 }

Implement the business logic.
For example, the URLResourceReader will obtain the resource through a connection:


  1
2
3
4
5
6
7

  URL url = uri.toURL();
URLConnection conn = url.openConnection();
String mimeType = conn.getContentType();
if ( mimeType == null ) {
    mimeType = URLConnection.guessContentTypeFromName( url.getFile() );
}
InputStream is = conn.getInputStream();

Note

The Resource needs to be accessible from the DDF installation (see the rootResourceDirectories property of the URLResourceReader). This includes being able to find a file locally or reach out to a remote URI. This may require Internet access, and DDF may need to be configured to use a proxy (http.proxyHost and http.proxyPort can be added to the system properties on the command line script).

Return Resource in ResourceResponse.

For example:


  1

  return ResourceResponseImpl( new ResourceImpl( new BufferedInputStream( is ), new MimeType( mimeType ), url.getFile() ) );

If the Resource cannot be found, throw a ResourceNotFoundException.

26.16.1.4. `getSupportedSchemes`

public Set<String> getSupportedSchemes();

This method lets the ResourceReader inform the CatalogFramework about the type of URI scheme that it accepts and should be passed. For single-use ResourceReaders (like a URLResourceReader), there may be only one scheme that it can accept while others may understand more than one. A ResourceReader must, at minimum, accept one qualifier. As mentioned before, this method is used by the CatalogFramework to determine which ResourceReader to invoke.

Note	`ResourceReader` extends `Describable` Additionally, there are other methods that are used to uniquely describe a `ResourceReader`. The `describe` methods are straight-forward and can be implemented with guidance from the Javadoc.

26.16.1.5. Export to OSGi Service Registry

In order for the ResourceReader to be used by the CatalogFramework, it should be exported to the OSGi Service Registry as a DDF.catalog.resource.ResourceReader.

See the XML below for an example:

Blueprint example


  1
2

  <bean id="customResourceReaderId]" class="example.resource.reader.impl.CustomResourceReader" />
<service ref="customResourceReaderId" interface="DDF.catalog.source.ResourceReader" />

26.17. Developing Resource Writers

A ResourceWriter is an object used to store or delete a Resource. ResourceWriter objects should be registered within the OSGi Service Registry, so clients can retrieve an instance when they need to store a Resource.

26.17.1. Create a New `ResourceWriter`

Complete the following procedure to create a ResourceWriter.

Create a Java class that implements the DDF.catalog.resource.ResourceWriter interface.

        }

}

Blueprint Service Registration Example

  ...
<service ref="ResourceWriterReference" interface="DDF.catalog.resource.ResourceWriter" />
...

Deploy the OSGi bundled packaged service to the DDF run-time (Refer to the OSGi Basics - Bundles section.)

Tip	ResourceWriter Javadoc Refer to the Catalog API Javadoc for more information about the methods required for implementing the interface.

26.18. Developing Filters

The common way to create a Filter is to use the GeoTools FilterFactoryImpl object, which provides Java implementations for the various types of filters in the Filter Specification. Examples are the easiest way to understand how to properly create a Filter and a Query.

Note	Refer to the GeoTools javadoc for more information on `FilterFactoryImpl`.

Warning

Implementing the Filter interface directly is only for extremely advanced use cases and is highly discouraged. Instead, use of the DDF-specific FilterBuilder API is recommended.

Developers create a Filter object in order to filter or constrain the amount of records returned from a Source. The OGC Filter Specification has several types of filters that can be combined in a tree-like structure to describe the set of metacards that should be returned.

Categories of Filters

Comparison Operators
Logical Operators
Expressions
Literals
Functions
Spatial Operators
Temporal Operators

26.18.1. Units of Measure

According to the OGC Filter Specifications: 09-026r1 and OGC Filter Specifications: 04-095 , units of measure can be expressed as a URI. To fulfill that requirement, DDF utilizes the GeoTools class org.geotools.styling.UomOgcMapping for spatial filters requiring a standard for units of measure for scalar distances. Essentially, the UomOgcMapping maps the OGC Symbology Encoding standard URIs to Java Units. This class provides three options for units of measure:

FOOT
METRE
PIXEL

DDF only supports FOOT and METRE since they are the most applicable to scalar distances.

26.18.2. Filter Examples

The example below illustrates creating a query, and thus an OGC Filter, that does a case-insensitive search for the phrase "mission" in the entire metacard’s text. Note that the OGC PropertyIsLike Filter is used for this simple contextual query.

String searchPhrase = "mission" ;
org.opengis.filter.Filter propertyIsLikeFilter =
    filterFactory.like(filterFactory.property(Metacard.ANY_TEXT), searchPhrase, wildcardChar, singleChar, escapeChar, isCaseSensitive);
DDF.catalog.operation.QueryImpl query = new QueryImpl( propertyIsLikeFilter );

The example below illustrates creating an absolute temporal query, meaning the query is searching for Metacards whose modified timestamp occurred during a specific time range. Note that this query uses the During OGC Filter for an absolute temporal query.

org.opengis.temporal.Instant endInstant = new org.geotools.temporal.object.DefaultInstant(new DefaultPosition(end));

org.opengis.temporal.Period period =  new org.geotools.temporal.object.DefaultPeriod(startInstant, endInstant);

String property = Metacard.MODIFIED ; // modified date of a metacard

org.opengis.filter.Filter filter = filterFactory.during( filterFactory.property(property), filterFactory.literal(period)  );

DDF.catalog.operation.QueryImpl query = new QueryImpl(filter) ;

26.18.2.1. Contextual Searches

Most contextual searches can be expressed using the PropertyIsLike filter. The special characters that have meaning in a PropertyIsLike filter are the wildcard, single wildcard, and escape characters (see Example Creating-Filters-1).

Table 98. `PropertyIsLike` Special Characters
Character	Description
Wildcard	Matches zero or more characters.
Single Wildcard	Matches exactly one character.
Escape	Escapes the meaning of the Wildcard, Single Wildcard, and the Escape character itself

Characters and words, such as AND, &, and, OR, |, or, NOT, ~, not, {, and }, are treated as literals in a PropertyIsLike filter. In order to create equivalent logical queries, a developer must instead use the Logical Operator filters {AND, OR, NOT}. The Logical Operator filters can be combined together with PropertyIsLike filters to create a tree that represents the search phrase expression.

String wildcardChar = "*" ; // used to match zero or more characters

Filter filter =
    filterFactory.and(
       filterFactory.like(filterFactory.property(Metacard.METADATA), "mission" ,
wildcardChar, singleChar, escapeChar, isCaseSensitive),
       filterFactory.like(filterFactory.property(Metacard.METADATA), "planning" ,
wildcardChar, singleChar, escapeChar, isCaseSensitive)
    );

DDF.catalog.operation.QueryImpl query = new QueryImpl( filter );

26.18.2.1.1. Tree View of Creating Filters

Filters used in DDF can always be represented in a tree diagram.

Filter Example Tree Diagram

26.18.2.1.2. XML View of Creating Filters

Another way to view this type of Filter is through an XML model, which is shown below.

           <PropertyName>metadata</PropertyName>
           <Literal>planning</Literal>
      </PropertyIsLike>
   <And>
</Filter>

Using the Logical Operators and PropertyIsLike filters, a developer can create a whole language of search phrase expressions.

26.18.2.2. Fuzzy Operations

DDF only supports one custom function. The Filter specification does not include a fuzzy operator, so a Filter function was created to represent a fuzzy operation. The function and class is called FuzzyFunction, which is used by clients to notify the Sources to perform a fuzzy search. The syntax expected by providers is similar to the Fuzzy Function. Refer to the example below.

boolean isCaseSensitive = false ;

Filter fuzzyFilter = filterFactory.like(
     new DDF.catalog.impl.filter.FuzzyFunction(
          Arrays.asList((Expression) (filterFactory.property(Metacard.ANY_TEXT))),
          filterFactory.literal("")),
     searchPhrase,
     wildcardChar,
     singleChar,
     escapeChar,
     isCaseSensitive);

QueryImpl query = new QueryImpl(fuzzyFilter);

26.18.3. Parsing Filters

According to the OGC Filter Specification 04-095 : a "(filter expression) representation can be … parsed and then transformed into whatever target language is required to retrieve or modify object instances stored in some persistent object store." Filters can be thought of as the WHERE clause for a SQL SELECT statement to "fetch data stored in a SQL-based relational database."

Sources can parse OGC Filters using the FilterAdapter and FilterDelegate. See Developing a Filter Delegate for more details on implementing a new FilterDelegate. This is the preferred way to handle OGC Filters in a consistent manner.

Alternately, org.opengis.filter.Filter implementations can be parsed using implementations of the interface org.opengis.filter.FilterVisitor. The FilterVisitor uses the Visitor pattern . Essentially, FilterVisitor instances "visit" each part of the Filter tree allowing developers to implement logic to handle the filter’s operations. GeoTools 8 includes implementations of the FilterVisitor interface. The DefaultFilterVisitor, as an example, provides only business logic to visit every node in the Filter tree. The DefaultFilterVisitor methods are meant to be overwritten with the correct business logic. The simplest approach when using FilterVisitor instances is to build the appropriate query syntax for a target language as each part of the Filter is visited. For instance, when given an incoming Filter object to be evaluated against a RDBMS, a CatalogProvider instance could use a `FilterVisitor to interpret each filter operation on the Filter object and translate those operations into SQL. The FilterVisitor may be needed to support Filter functionality not currently handled by the FilterAdapter and FilterDelegate reference implementation.

26.18.3.1. Interpreting a Filter to Create SQL

If the FilterAdapter encountered or "visited" a PropertyIsLike filter with its property assigned as title and its literal expression assigned as mission, the FilterDelegate could create the proper SQL syntax similar to title LIKE mission.

Parsing Filters Tree Diagram

26.18.3.2. Interpreting a Filter to Create XQuery

If the FilterAdapter encountered an OR filter, such as in Figure Parsing-Filters2 and the target language was XQuery, the FilterDelegate could yield an expression such as

ft:query(//inventory:book/@subject,'math') union
ft:query(//inventory:book/@subject,'science').

Parsing Filters XQuery

26.18.3.2.1. FilterAdapter/Delegate Process for Figure Parsing

FilterAdapter visits the OR filter first.
OR filter visits its children in a loop.
The first child in the loop that is encountered is the LHS PropertyIsLike.
The FilterAdapter will call the FilterDelegate `PropertyIsLike`method with the LHS property and literal.
The LHS PropertyIsLike delegate method builds the XQuery syntax that makes sense for this particular underlying object store. In this case, the subject property is specific to this XML database, and the business logic maps the subject property to its index at //inventory:book/@subject Note that ft:query in this instance is a custom XQuery module for this specific XML database that does full text searches.
The FilterAdapter then moves back to the OR filter, which visits its second child.
The FilterAdapter will call the FilterDelegate PropertyIsLike method with the RHS property and literal.
The RHS PropertyIsLike delegate method builds the XQuery syntax that makes sense for this particular underlying object store. In this case, the subject property is specific to this XML database, and the business logic maps the subject property to its index at //inventory:book/@subject Note that ft:query in this instance is a custom XQuery module for this specific XML database that does full text searches. . The FilterAdapter then moves back to its `OR Filter which is now done with its children.
It then collects the output of each child and sends the list of results to the FilterDelegate OR method.
The final result object will be returned from the FilterAdapter adapt method.

26.18.3.2.2. FilterVisitor Process for Figure Parsing

FilterVisitor visits the OR filter first.
OR filter visits its children in a loop.
The first child in the loop that is encountered is the LHS PropertyIsLike.
The LHS PropertyIsLike builds the XQuery syntax that makes sense for this particular underlying object store. In this case, the subject property is specific to this XML database, and the business logic maps the subject property to its index at //inventory:book/@subject. Note that ft:query in this instance is a custom XQuery module for this specific XML database that does full text searches.
The FilterVisitor then moves back to the OR filter, which visits its second child.
The RHS PropertyIsLike builds the XQuery syntax that makes sense for this particular underlying object store. In this case, the subject property is specific to this XML database, and the business logic maps the subject property to its index at //inventory:book/@subject. Note that ft:query in this instance is a custom XQuery module for this specific XML database that does full text searches.
The FilterVisitor then moves back to its OR filter, which is now done with its children. It then collects the output of each child and could potentially execute the following code to produce the above expression.

  public visit( Or filter, Object data) {

   /* the equivalent statement for the OR filter in this domain (XQuery) */
   xQuery = childFilter1Output + " union " + childFilter2Output;
...
}

26.18.4. Filter Profile

The filter profile maps filters to metacard types.

26.18.4.1. Role of the OGC Filter

Both Queries and Subscriptions extend the OGC GeoAPI Filter interface.

The Filter Builder and Adapter do not fully implement the OGC Filter Specification. The filter support profile contains suggested filter to metacard type mappings. For example, even though a Source could support a PropertyIsGreaterThan filter on XML_TYPE, it would not likely be useful.

26.18.4.2. Catalog Filter Profile

The following table displays the common metacard attributes with their respective types for reference.

Table 99. Metacard Attribute To Type Mapping
Metacard Attribute	Metacard Type
ANY_DATE	DATE_TYPE
ANY_GEO	GEO_TYPE
ANY_TEXT	STRING_TYPE
CONTENT_TYPE	STRING_TYPE

TITLE	STRING_TYPE

26.18.4.2.1. Comparison Operators

Comparison operators compare the value associated with a property name with a given Literal value. Endpoints and sources should try to use metacard types other than the object type. The object type only supports backwards compatibility with java.net.URI. Endpoints that send other objects will not be supported by standard sources. The following table maps the metacard types to supported comparison operators.

Table 100. Metacard Types to Comparison Operators
PropertyIs	Between	EqualTo	GreaterThan	GreaterThan	OrEqualTo	LessThan	LessThan	OrEqualTo	Like	NotEqualTo	Null
BINARY_TYPE		X
BOOLEAN_TYPE		X
DATE_TYPE	X	X	X	X	X	X	X	X		X	X

PropertyIsEqualTo	Property == Literal
PropertyIsGreaterThan	Property > Literal
PropertyIsGreaterThanOrEqualTo	Property >= Literal
PropertyIsLessThan	Property < Literal
PropertyIsLessThanOrEqualTo	Property ⇐ Literal
PropertyIsLike	Property LIKE Literal Equivalent to SQL "like"
PropertyIsNotEqualTo	Property != Literal
PropertyIsNull	Property == null

26.18.4.2.2. Logical Operators

Logical operators apply Boolean logic to one or more child filters.

Table 102. Supported Logical Operators
	And	Not	Or
Supported Filters	X	X	X

26.18.4.2.3. Temporal Operators

Temporal operators compare a date associated with a property name to a given Literal date or date range.

Table 103. Supported Temporal Operators
	After	AnyInteracts	Before	Begins	BegunBy	During	EndedBy	Meets	MetBy	OverlappedBy	TContains
DATE_TYPE	X		X			X

Literal values can be either date instants or date periods.

Table 104. Temporal Operator Descriptions
Operator	Description
After	Property > (Literal \|\| Literal.end)
Before	Property < (Literal \|\| Literal.start)
During	Literal.start < Property < Literal.end

26.18.4.2.4. Spatial Operators

Spatial operators compare a geometry associated with a property name to a given Literal geometry.

Table 105. Supported Spatial Operators.
BBox	Beyond	Contains	Crosses	Disjoint	Equals	DWithin	Intersects	Overlaps	Touches	Within
GEO_TYPE		X	X	X	X		X	X	X

Geometries are usually represented as Well-Known Text (WKT).

Table 106. Spatial Operator Descriptions
Operator	Description
Beyond	Property geometries beyond given distance of Literal geometry
Contains	Property geometry contains Literal geometry
Crosses	Property geometry crosses Literal geometry
Disjoint	Property geometry direct positions are not interior to Literal geometry
DWithin	Property geometry lies within distance to Literal geometry
Intersects	Property geometry intersects Literal geometry; opposite to the Disjoint operator
Overlaps	Property geometry interior overlaps Literal geometry interior somewhere
Touches	Property geometry touches but does not overlap Literal geometry
Within	Property geometry completely contains Literal geometry

26.19. Developing Filter Delegates

Filter Delegates help reduce the complexity of parsing OGC Filters. The reference Filter Adapter implementation contains the necessary boilerplate visitor code and input normalization to handle commonly supported OGC Filters.

26.19.1. Creating a New Filter Delegate

A Filter Delegate contains the logic that converts normalized filter input into a form that the target data source can handle. Delegate methods will be called in a depth first order as the Filter Adapter visits filter nodes.

26.19.1.1. Implementing the Filter Delegate

Create a Java class extending FilterDelegate.
public class ExampleDelegate extends DDF.catalog.filter.FilterDelegate<ExampleReturnObjectType> {
FilterDelegate will throw an appropriate exception for all methods not implemented. Refer to the DDF JavaDoc for more details about what is expected of each FilterDelegate method.

Note	A code example of a Filter Delegate can be found in `DDF.catalog.filter.proxy.adapter.test` of the `filter-proxy` bundle.

26.19.1.2. Throwing Exceptions

Filter delegate methods can throw UnsupportedOperationException run-time exceptions. The GeotoolsFilterAdapterImpl will catch and re-throw these exceptions as UnsupportedQueryExceptions.

26.19.1.3. Using the Filter Adapter

The FilterAdapter can be requested from the OSGi registry.

<reference id="filterAdapter" interface="DDF.catalog.filter.FilterAdapter" />

The Query in a QueryRequest implements the Filter interface. The Query can be passed to a FilterAdapter and FilterDelegate to process the Filter.

    throws DDF.catalog.source.UnsupportedQueryException {

    DDF.catalog.operation.Query query = queryRequest.getQuery();

    DDF.catalog.filter.FilterDelegate<ExampleReturnObjectType> delegate = new ExampleDelegate();

    // DDF.catalog.filter.FilterAdapter adapter injected via Blueprint
    ExampleReturnObjectType result = adapter.adapt(query, delegate);
}

Import the Catalog API Filter package and the reference implementation package of the Filter Adapter in the bundle manifest (in addition to any other required packages).
Import-Package: DDF.catalog, DDF.catalog.filter, DDF.catalog.source

26.19.1.4. Filter Support

Not all OGC Filters are exposed at this time. If demand for further OGC Filter functionality is requested, it can be added to the Filter Adapter and Delegate so sources can support more complex filters. The following OGC Filter types are currently available:

Logical

Property Comparison

PropertyIsBetween

Beyond

True if the geometry being tested is beyond the stated distance of the geometry provided.

Contains

True if the second geometry is wholly inside the first geometry.

Crosses

True if: * the intersection of the two geometries results in a value whose dimension is less than the geometries * the maximum dimension of the intersection value includes points interior to both the geometries * the intersection value is not equal to either of the geometries.

Disjoint

True if the two geometries do not touch or intersect.

DWithin

True if the geometry being tested is within the stated distance of the geometry provided.

Intersects

True if the two geometries intersect. This is a convenience method as Not Disjoint(A,B) gets the same result.

Overlaps

True if the intersection of the geometries results in a value of the same dimension as the geometries that is different from both of the geometries.

26.20. Developing Action Components

To provide a service, such as a link to a metacard, the ActionProvider interface should be implemented. An ActionProvider essentially provides a List of Actions when given input that it can recognize and handle. For instance, if a REST endpoint ActionProvider was given a metacard, it could provide a link based on the metacard’s ID. An Action Provider performs an action when given a subject that it understands. If it does not understand the subject or does not know how to handle the given input, it will return Collections.emptyList(). An Action Provider is required to have an ActionProvider id. The Action Provider must register itself in the OSGi Service Registry with the ddf.action.ActionProvider interface and must also have a service property value for id. An action is a URL that, when invoked, provides a resource or executes intended business logic.

26.20.1. Action Component Naming Convention

For each Action, a title and description should be provided to describe what the action does. The recommended naming convention is to use the verb 'Get' when retrieving a portion of a metacard, such as the metadata or thumbnail, or when downloading a product. The verb 'Export' or the expression 'Export as' is recommended when the metacard is being exported in a different format or presented after going some transformation.

26.20.1.1. Action Component Taxonomy

An Action Provider registers an id as a service property in the OGSi Service Registry based on the type of service or action that is provided. Regardless of implementation, if more than one Action Provider provides the same service, such as providing a URL to a thumbnail for a given metacard, they must both register under the same id. Therefore, Action Provider implementers must follow an Action Taxonomy.

The following is a sample taxonomy:

catalog.data.metacard shall be the grouping that represents Actions on a Catalog metacard.
1. catalog.data.metacard.view
2. catalog.data.metacard.thumbnail
3. catalog.data.metacard.html
4. catalog.data.metacard.resource
5. catalog.data.metacard.metadata

Table 107. Action ID Service Descriptions
ID	Required Action	Naming Convention
`catalog.data.metacard.view`	Provides a valid URL to view a metacard. Format of data is not specified; i.e. the representation can be in XML, JSON, or other.	Export as …
`catalog.data.metacard.thumbnail`	Provides a valid URL to the bytes of a thumbnail (`Metacard.THUMBNAIL`) with MIME type image/jpeg.	Export as Thumbnail
`catalog.data.metacard.map.overlay.thumbnail`	Provides a metacard URL that translates the metacard into a geographically aligned image (suitable for overlaying on a map).	Export as Thumbnail Overlay
`catalog.data.metacard.html`	Provides a valid URL that, when invoked, provides an HTML representation of the metacard.	Export as HTML
`catalog.data.metacard.xml`	Provides a valid URL that, when invoked, provides an XML representation of the metacard.	Export as XML
`catalog.data.metacard.geojson`	Provides a valid URL that, when invoked, provides an XML representation of the metacard.	Export as GeoJSON
`catalog.data.metacard.resource`	Provides a valid URL that, when invoked, provides the underlying resource of the metacard.	Export as Resource
`catalog.data.metacard.metadata`	Provides a valid URL to the XML metadata in the metacard (`Metacard.METADATA`).	Export as Metadata

26.21. Developing Query Options

The easiest way to create a Query is to use the ddf.catalog.operation.QueryImpl object. It is first necessary to create an OGC Filter object then set the Query Options after QueryImpl has been constructed.

QueryImpl Example

  /*
  Builds a query that requests a total results count and
  that the first record to be returned is the second record found from
  the requested set of metacards.
 */

 String property = ...;

 String value = ...;

 org.geotools.filter.FilterFactoryImpl filterFactory = new FilterFactoryImpl() ;

 QueryImpl query = new QueryImpl( filterFactory.equals(filterFactory.property(property),

filterFactory.literal(value))) ;

 query.setStartIndex(2) ;

 query.setRequestsTotalResultsCount(true);

26.21.1. Evaluating a query

Every Source must be able to evaluate a Query object. Nevertheless, each Source could evaluate the Query differently depending on what that Source supports as to properties and query capabilities. For instance, a common property all Sources understand is id, but a Source could possibly store frequency values under the property name "frequency." Some Sources may not support frequency property inquiries and will throw an error stating it cannot interpret the property. In addition, some Sources might be able to handle spatial operations, while others might not. A developer should consult a Source’s documentation for the limitations, capabilities, and properties that a Source can support.

Table 108. Query Options
Option	Description
`StartIndex`	1-based index that states which metacard the Source should return first out of the requested metacards.
`PageSize`	Represents the maximum amount of metacards the Source should return.
`SortBy`	Determines how the results are sorted and on which property.
`RequestsTotalResultsCount`	Determines whether the total number of results should be returned.
`TimeoutMillis`	The amount of time in milliseconds before the query is to be abandoned. If a zero or negative timeout is set, the catalog framework will default to a value configurable via the Admin UI under Catalog → Configuration → Query Operations.

26.21.2. Commons-DDF Utilities

The `commons-DDF`bundle provides utilities and functionality commonly used across other DDF components, such as the endpoints and providers.

26.21.2.1. FuzzyFunction

DDF.catalog.impl.filter.FuzzyFunction class is used to indicate that a PropertyIsLike filter should interpret the search as a fuzzy query.

26.21.2.2. XPathHelper

DDF.util.XPathHelper provides convenience methods for executing XPath operations on XML. It also provides convenience methods for converting XML as a String from a org.w3c.dom.Document object and vice versa.

26.22. Configuring Managed Service Factory Bundles

26.22.1. Configuring Managed Service Factory Bundles

Services that are created using a Managed Service Factory can be configured using .config files as well. These configuration files, however, follow a different naming convention than .cfg files. The filenames must start with the Managed Service Factory PID, be followed by a dash and a unique identifier, and have a .config extension. For instance, assuming that the Managed Service Factory PID is org.codice.ddf.factory.pid and two instances of the service need to be configured, files org.codice.ddf.factory.pid-<UNIQUE ID 1>.config and org.codice.ddf.factory.pid-<UNIQUE ID 2>.config should be created and added to <DDF_HOME>/etc.

The unique identifiers used in the file names have no impact on the order in which the configuration files are processed. No specific processing order should be assumed. Also, a new service will be created and configured every time a configuration file matching the Managed Service Factory PID is added to the directory, regardless of the unique id used.

Any service.factoryPid and service.pid values in these .config files will be overridden by the values parsed from the file name, so .config files should not contain these properties.

26.22.1.1. File Format

The basic syntax of the .config configuration files is similar to the older .cfg files but introduces support for lists and types other than simple strings. The type associated with a property must match the type attribute used in the corresponding metatype.xml file when applicable.

The following table shows the format to use for each property type supported.

Table 109. Property Formats
Type	Format (see details below for variations)	Example
String	name="value"	`name="John"`
Boolean	name=B"true\|false"	`authorized=B"true"`
Integer	name=I"value"	`timeout=I"10"`
Long	name=L"value"	`diameter=L"100"`
Float	name=F"value"	`cost=F"1093140480"`
Double	name=D"value"	`latitude=D"4636745974857667812"`
List of Strings	name=["value1","value2",…]	`complexStringArray=[ \ "{\"url\"\ \"http://test.sample.com\"\ \"layers\"\ [\"0\"]\ \"VERSION\"\ \"1.1\|1.2\"\ \"image/png\"}\ \"beta\"\ 1}", \ "{\"url\"\ \"http://test.sample.com"\ 0.5}", \ "/security-config\=SAML\|basic", \ ]`
List of Booleans	name=B["true\|false","true\|false",…]	`authorizedList=B[ \ "true", \ "false", \ ]`
List of Integers	name=I["value1","value2",…]	`sizes=I[ \ "10", \ "20", \ "30", \ ]`
List of Longs	name=L["value1","value2",…]	`sizes=L[ \ "100", \ "200", \ "300", \ ]`
List of Floats	name=F["value1","value2",…]	`sizes=F[ \ "1066192077", \ "1074580685", \ "1079194419", \ ]`
List of Doubles	name=D["value1","value2",…]	`sizes=D[ \ "4607736361554183979", \ "4612212939583790252", \ "4614714689176794563", \ ]`

Note

Values with types other than String must be prefixed with a lower-case or upper-case character. See the examples in the table.
- Boolean: B or b
- Integer: I or i
- Long: L or l
- Float: F or f
- Double: D or d
Equal signs (=), double quotes ("), and spaces within values must must be escaped using a backslash (\).
When properties are split over multiple lines for readability, end of lines must be specified with a backslash (\). See the examples for lists in the table.
A comma (,) after the last value in a list is optional.
Surrounding the equal signs (=) with spaces for properties is optional. Because there is a known issue when using OPS4J Pax Exam 4.11.0 and modifying .config files that include spaces, all default .config files that may be modified in OPS4J Pax Exam 4.11.0 tests should not include spaces.
Boolean values will default to false if any value other than true is provided.
Float values must be representated in the IEEE 754 floating-point "single format" bit layout, preserving Not-a-Number (NaN) values. For example, F"1093140480" corresponds to F"10.5". See the documentation for java.lang.Integer#parseInt(java.lang.String) and java.lang.Float#intBitsToFloat(int) for more details.
Double values must be represented in the IEEE 754 floating-point "double format" bit layout, preserving Not-a-Number (NaN) values. For example, D"4636745974857667812" corresponds to D"100.1234". See the documentation for java.lang.Long#parseLong(java.lang.String) and java.lang.Double#longBitsToDouble for more details.

26.23. Developing XACML Policies

This document assumes familiarity with the XACML schema and does not go into detail on the XACML language. When creating a policy, a target is used to indicate that a certain action should be run only for one type of request. Targets can be used on both the main policy element and any individual rules. Targets are geared toward the actions that are set in the request. These actions generally consist of the standard CRUD operations (create, read, update, delete) or a SOAPAction if the request is coming through a SOAP endpoint.

Note	These are only the action values that are currently created by the components that come with DDF. Additional components can be created and added to DDF to identify specific actions.

In the examples below, the policy has specified targets for the above type of calls. For the Filtering code, the target was set for "filter", and the Service validation code targets were geared toward two services: query and LocalSiteName. In a production environment, these actions for service authorization will generally be full URNs that are described within the SOAP WSDL.

26.23.1. XACML Policy Attributes

Attributes for the XACML request are populated with the information in the calling subject and the resource being checked.

26.23.2. XACML Policy Subject

The attributes for the subject are obtained from the SAML claims and populated within the XACML policy as individual attributes under the urn:oasis:names:tc:xacml:1.0:subject-category:access-subject category. The name of the claim is used for the AttributeId value. Examples of the items being populated are available at the end of this page.

26.23.3. XACML Policy Resource

The attributes for resources are obtained through the permissions process. When checking permissions, the XACML processing engine retrieves a list of permissions that should be checked against the subject. These permissions are populated outside of the engine and should be populated with the attributes that should be asserted against the subject. When the permissions are of a key-value type, the key being used is populated as the AttributeId value under the urn:oasis:names:tc:xacml:3.0:attribute-category:resource category.

26.23.4. Using a XACML Policy

To use a XACML policy, copy the XACML policy into the <DDF_HOME>/etc/pdp/policies directory.

26.24. Assuring Authenticity of Bundles and Applications

DDF Artifacts in the JAR file format (such as bundles or KAR files) can be signed and verified using the tools included as part of the Java Runtime Environment.

26.24.1. Prerequisites

To work with Java signatures, a keystore/truststore is required. For testing or trial purposes DDF can sign and validate using a self-signed certificate, generated with the keytool utility. In an actuall installation, a certificate issued from a trusted Certificate Authority will be used.

Additional documentation on keytool can be found at Keytool home .

Using keytool to generate a self-signed certificate keystore

~ $ keytool -genkey -keyalg RSA -alias selfsigned -keystore keystore.jks -storepass password -validity 360 -keysize 2048
What is your first and last name?
  [Unknown]:  Nick Fury
What is the name of your organizational unit?
  [Unknown]:  Marvel
What is the name of your organization?
  [Unknown]:  SHIELD
What is the name of your City or Locality?
  [Unknown]:  New York
What is the name of your State or Province?
  [Unknown]:  NY
What is the two-letter country code for this unit?
  [Unknown]:  US
Is CN=Nick Fury, OU=SHIELD, O=Marvel, L="New  York", ST=NY, C=US correct?
  [no]:  yes
Enter key password for <selfsigned>
    (RETURN if same as keystore password):
Re-enter new password:

26.24.2. Signing a JAR/KAR

Once a keystore is available, the JAR can be signed using the jarsigner tool.

Additional documentation on jarsigner can be found at Jarsigner .

Using jarsigner to sign a KAR

~ $ jarsigner -keystore keystore.jks -keypass shield -storepass password  catalog-app-2.5.1.kar selfsigned

26.24.2.1. Verifying a JAR/KAR

The jarsigner utility is also used to verify a signature in a JAR-formatted file.

Using jarsigner to verify a file

~ $ jarsigner -verify -verbose -keystore keystore.jks catalog-app-2.5.1.kar
        9447 Mon Oct 06 17:05:46 MST 2014 META-INF/MANIFEST.MF

Note the last line: jar verified. This indicates that the signatures used to sign the JAR (or in this case, KAR) were valid according to the trust relationships specified by the keystore.

26.25. WFS Services

The Web Feature Service (WFS) is an Open Geospatial Consortium (OGC) Specification. DDF supports the ability to integrate WFS 1.0, 1.1, and 2.0 Web Services.

Note	DDF does not include a supported WFS Web Service (Endpoint) implementation. Therefore, federation for 2 DDF instances is not possible via WFS.

WFS Features

When a query is issued to a WFS server, the output of the query is an XML document that contains a collection of feature member elements. Each WFS server can have one or more feature types with each type being defined by a schema that extends the WFS featureMember schema. The schema for each type can be discovered by issuing a DescribeFeatureType request to the WFS server for the feature type in question. The WFS source handles WFS capability discovery and requests for feature type description when an instance of the WFS source is configured and created.

See the WFS v1.0.0 Source, WFS v1.1.0 Source, or WFS v2.0.0 Source for more information about how to configure a WFS source.

Converting a WFS Feature

In order to expose WFS features to DDF clients, the WFS feature must be converted into the common data format of the DDF, a metacard. The OGC package contains a GenericFeatureConverter that attempts to populate mandatory metacard fields with properties from the WFS feature XML. All properties will be mapped directly to new attributes in the metacard. However, the GenericFeatureConverter may not be able to populate the default metacard fields with properties from the feature XML.

Creating a Custom Converter

To more accurately map WFS feature properties to fields in the metacard, a custom converter can be created. The OGC package contains an interface, FeatureConverter, which extends the http://xstream.codehaus.org/javadoc/com/thoughtworks/xstream/converters/Converter.htmlConverter interface provided by the XStream project. XStream is an open source API for serializing XML into Java objects and vice-versa. Additionally, a base class, AbstractFeatureConverter, has been created to handle the mapping of many fields to reduce code duplication in the custom converter classes.

Create the CustomConverter class extending the ogc.catalog.common.converter.AbstractFeatureConverter class.
```
public class CustomConverter extends ogc.catalog.common.converter.AbstractFeatureConverter
```

Implement the FeatureConverterFactory interface and the createConverter() method for the CustomConverter.

    }
    public FeatureConverter createConverter() {
        return new CustomConverter();
    }
    public String getFeatureType() {
        return featureType;
    }
}

Implement the unmarshal method required by the FeatureConverter interface. The createMetacardFromFeature(reader, metacardType) method implemented in the AbstractFeatureConverter is recommended.

  public Metacard unmarshal(HierarchicalStreamReader reader, UnmarshallingContext ctx) {

  //set your feature specific fields on the metacard object here
  //
  //if you want to map a property called "beginningDate" to the Metacard.createdDate field
  //you would do:
  mc.setCreatedDate(mc.getAttribute("beginningDate").getValue());
}

Export the ConverterFactory to the OSGi registry by creating a blueprint.xml file for its bundle. The bean id and argument value must match the WFS Feature type being converted.

26.26. JSON Definition Files

DDF supports adding new attribute types, metacard types, validators, and more using json-formatted definition files.

The following may be defined in a JSON definition file:

Attribute Types
Metacard Types
Global Attribute Validators
Default Attribute Values
Attribute Injections

26.26.1. Definition File Format

A definition file follows the JSON format as specified in ECMA-404 . All definition files must be valid JSON in order to be parsed.

A single definition file may define as many of the types as needed. This means that types can be defined across multiple files for grouping or clarity.

26.26.2. Deploying Definition Files

The file must have a .json extension in order to be picked up by the deployer. Once the definition file is ready to be deployed, put the definition file <filename>.json into the etc/definitions folder.

Definition files can be added, updated, and/or deleted in the etc/definitions folder. The changes are applied dynamically and no restart is required.

If a definition file is removed from the etc/definitions folder, the changes that were applied by that file will be undone.

26.27. Developing Subscriptions

Subscriptions represent "standing queries" in the Catalog. Like a query, subscriptions are based on the OGC Filter specification.

26.27.1. Subscription Lifecycle

A Subscription itself is a series of events during which various plugins or transformers can be called to process the subscription.

26.27.1.1. Creation

Subscriptions are created directly with the Event Processor or declaratively through use of the Whiteboard Design Pattern.
The Event Processor will invoke each Pre-Subscription Plugin and, if the subscription is not rejected, the subscription will be activated.

26.27.1.2. Evaluation

When a metacard matching the subscription is created, updated, or deleted in any Source, each Pre-Delivery Plugin will be invoked.
If the delivery is not rejected, the associated Delivery Method callback will be invoked.

26.27.1.3. Update Evaluation

Notably, the Catalog allows event evaluation on both the previous value (if available) and new value of a Metacard when an update occurs.

26.27.1.4. Durability

Subscription durability is not provided by the Event Processor. Thus, all subscriptions are transient and will not be recreated in the event of a system restart. It is the responsibility of Endpoints using subscriptions to persist and re-establish the subscription on startup. This decision was made for the sake of simplicity, flexibility, and the inability of the Event Processor to recreate a fully-configured Delivery Method without being overly restrictive.

Important

Subscriptions are not persisted by the Catalog itself.
Subscriptions must be explicitly persisted by an endpoint and are not persisted by the Catalog. The Catalog Framework, or more specifically the Event Processor itself, does not persist subscriptions. Certain endpoints, however, can persist the subscriptions on their own and recreate them on system startup.

26.27.2. Creating a Subscription

Currently, the Catalog reference implementation does not contain a subscription endpoint. Therefore, an endpoint that exposes a web service interface to create, update, and delete subscriptions would provide a client’s subscription filtering criteria to be used by Catalog’s Event Processor to determine which events are of interest to the client. The endpoint client also provides the callback URL of the event consumer to be called when an event matching the subscription’s criteria is found. This callback to the event consumer is made by a Delivery Method implementation that the client provides when the subscription is created. Whenever an event occurs in the Catalog matching the subscription, the Delivery Method implementation will be called by the Event Processor. The Delivery Method will, in turn, send the event notification out to the event consumer. As part of the subscription creation process, the Catalog verifies that the event consumer at the specified callback URL is available to receive callbacks. Therefore, the client must ensure the event consumer is running prior to creating the subscription. The Catalog completes the subscription creation by executing any pre-subscription Catalog Plugins, and then registering the subscription with the OSGi Service Registry. The Catalog does not persist subscriptions by default.

26.27.2.1. Event Processing and Notification

If an event matches a subscription’s criteria, any pre-delivery plugins that are installed are invoked, the subscription’s DeliveryMethod is retrieved, and its operation corresponding to the type of ingest event is invoked. For example, the DeliveryMethod created() function is called when a metacard is created. The DeliveryMethod operations subsequently invoke the corresponding operation in the client’s event consumer service, which is specified by the callback URL provided when the DeliveryMethod was created. An internal subscription tracker monitors the OSGi registry, looking for subscriptions to be added (or deleted). When it detects a subscription being added, it informs the Event Processor, which sets up the subscription’s filtering and is responsible for posting event notifications to the subscriber when events satisfying their criteria are met.

The Standard Event Processor is an implementation of the Event Processor and provides the ability to create/delete subscriptions. Events are generated by the CatalogFramework as metacards are created/updated/deleted and the Standard Event Processor is called since it is also a Post-Ingest Plugin. The Standard Event Processor checks each event against each subscription’s criteria.

When an event matches a subscription’s criteria the Standard Event Processor:

invokes each pre-delivery plugin on the metacard in the event.
invokes the DeliveryMethod operation corresponding to the type of event being processed, e.g., created() operation for the creation of a metacard.

Available Event Processor

Standard Event Processor

26.27.2.1.1. Using DDF Implementation

If applicable, the implementation of Subscription that comes with DDF should be used. It is available at ddf.catalog.event.impl.SubscriptionImpl and offers a constructor that takes in all of the necessary objects. Specifically, all that is needed is a Filter, DeliveryMethod, Set<String> of source IDs, and a boolean for enterprise.

The following is an example code stub showing how to create a new instance of Subscription using the DDF implementation.

  // Create a new filter using an imported FilterBuilder
Filter filter = filterBuilder.attribute(Metacard.ANY_TEXT).like().text("*");
 
// Create a implementation of DeliveryMethod
DeliveryMethod deliveryMethod = new MyCustomDeliveryMethod();
 
// Create a set of source ids
// This set is empty as the subscription is not specific to any sources
Set<String> sourceIds = new HashSet<String>();
 
// Set the isEnterprise boolean value
// This subscription example should notifications from all sources (not just local)
boolean isEnterprise = true;

Subscription subscription = new SubscriptionImpl(filter, deliveryMethod, sourceIds,isEnterprise);

26.27.2.2. Delivery Method

A Delivery Method provides the operation (created, updated, deleted) for how an event’s metacard can be delivered.

A Delivery Method is associated with a subscription and contains the callback URL of the event consumer to be notified of events. The Delivery Method encapsulates the operations to be invoked by the Event Processor when an event matches the criteria for the subscription. The Delivery Method’s operations are responsible for invoking the corresponding operations on the event consumer associated with the callback URL.

26.28. Contributing to Documentation

DDF documentation is included in the source code, so it is edited and maintained in much the same way.

src/main/resources

Table 110. Documentation Directory Structure and Contents
`Directory`	Contents
`content`	Asciidoctor-formatted files containing documentation contents and the header information needed to organize them.
`images`	Screenshots, icons, and other image files used in documentation.
`templates`	Template files used to compile the documentation for display.
`jbake.properties`	Properties file defining content types and other parameters.

26.28.1. Editing Existing Documentation

Update existing content when code behavior changes, new capabilities are added to features, or the configuration process changes. Content is organized within the content directory in sub directories according to the audience and purpose for each document in the documentation library. Use this list to determine placement of new content.

Documentation Sections

Introduction/Core Concepts: This section is intended to be a high-level, executive summary of the features and capabilities of DDF. Content here should be written at a non-technical level.
Quick Start: This section is intended for getting set up with a test, demonstration, or trial instance of DDF. This is the place for non-production shortcuts or workarounds that would not be used in a secured, hardened installation.
Managing: The managing section covers "how-to" instructions to be used to install, configure, and maintain an instance of DDF in a production environment. This content should be aimed at system administrators. Security hardening should be integrated into these sections.
Using: This section is primarily aimed at the final end users who will be performing tasks with DDF. This content should guide users through common tasks and user interfaces.
Integrating: This section guides developers building other projects looking to connect to new or existing instances of DDF.
Developing: This section provides guidance and best practices on developing custom implementations of DDF components, especially ones that may be contributed into the code baseline.
Architecture: This section is a detailed description of the architectural design of DDF and how components work together.
Reference: This section is a comprehensive list of features and possible configurations.
Metadata Reference: This section details how metadata is extracted and normalized by DDF.
Documentation: This is a collection of all of the individual documentation pages in one html or pdf file.

See the style guide for more guidance on stylistic and formatting concerns.

26.28.2. Adding New Documentation Content

If creating a new section is required, there are some minimal requirements for a new .adoc file.

Header content

The templates scan the header information to place it into the correct place within the documentation. Different sections have different headers required, but some common attributes are always required.

type: roughly maps to the section or subSection of the documentation.
title: title of the section or subsection contained in the file.
status: set to published to include within the documentation, set to draft to hide a work-in-progress section.
order: used in sections where order needs to be enforced.
summary: brief summary of section contents. Some, but not all, summaries are included by templates.

26.28.3. Creating a New Documentation Template

To create a new, standalone documentation page, create a new template in the templates directory. Optionally, this template can include some of the internal templates in the templates/build directory, but this is not required.

For guidance on using the freemarker syntax, see the Freemarker documentation .

26.28.4. Extending Documentation in Downstream Distributions

By mimicking the build and directory structure of the documentation, downstream projects are able to leverage the existing documentation and insert content before and after sections of the DDF documentation.

Documentation Module Directory Structure

-docs
  -src
    -main
      -resources
        -content
        -images
        -templates

content: Contains the .adoc files that make up the content. Sub-directories are organized according to the documents that make up the main library.
images: any pre-existing images, such as screenshots, to be included in the documentation.
templates: template files used to create documentation artifacts. A build sub-directory holds the templates that will not be standalone documents to render specific sections.

27. Development Guidelines

27.1. Contributing

The Distributed Data Framework is free and open-source software offered under the GNU Lesser General Public License. The DDF is managed under the guidance of the Codice Foundation . Contributions are welcomed and encouraged. Please visit the Codice DDF Contributor Guidelines and the DDF source code repository for more information.

27.2. OSGi Basics

DDF runs on top of an OSGi framework, a Java virtual machine (JVM), several choices of operating systems, and the physical hardware infrastructure. The items within the dotted line represent the standard DDF components.

DDF is a customized and branded distribution of Apache Karaf . DDF could also be considered to be a more lightweight OSGi distribution, as compared to Apache ServiceMix, FUSE ESB, or Talend ESB, all of which are also built upon Apache Karaf. Similar to its peers, DDF incorporates (additional upstream dependencies ).

The DDF framework hosts DDF applications, which are extensible by adding components via OSGi. The best example of this is the DDF Catalog (API), which offers extensibility via several types of Catalog Components. The DDF Catalog API serves as the foundation for several applications and resides in the applications tier.

The Catalog Components consist of Endpoints, Plugins, Catalog Frameworks, Sources, and Catalog Providers. Customized components can be added to DDF.

Capability: A general term used to refer to an ability of the system.
Component: Represents a portion of an Application that can be extended.
Bundle: Java Archives (JARs) with special OSGi manifest entries.
Feature: One or more bundles that form an installable unit; defined by Apache Karaf but portable to other OSGi containers.
Application: A JSON file defining a collection of bundles with configurations to be displayed in the Admin Console.

27.2.1. Packaging Capabilities as Bundles

Services and code are physically deployed to DDF using bundles. The bundles within DDF are created using the maven bundle plug-in. Bundles are Java JAR files that have additional metadata in the MANIFEST.MF that is relevant to an OSGi container.

The best resource for learning about the structure and headers in the manifest definition is in section 3.6 of the OSGi Core Specification . The bundles within DDF are created using the maven bundle plug-in , which uses the BND tool .

Tip	Alternative Bundle Creation Methods Using Maven is not necessary to create bundles. Many alternative tools exist, and OSGi manifest files can also be created by hand, although hand-editing should be avoided by most developers.

27.2.1.1. Creating a Bundle

27.2.1.1.1. Bundle Development Recommendations

Avoid creating bundles by hand or editing a manifest file: Many tools exist for creating bundles, notably the Maven Bundle plugin, which handle the details of OSGi configuration and automate the bundling process including generation of the manifest file.
Always make a distinction on which imported packages are optional or required: Requiring every package when not necessary can cause an unnecessary dependency ripple effect among bundles.
Embedding is an implementation detail: Using the Embed-Dependency instruction provided by the maven-bundle-plugin will insert the specified jar(s) into the target archive and add them to the Bundle-ClassPath. These jars and their contained packages/classes are not for public consumption; they are for the internal implementation of this service implementation only.
Bundles should never be embedded: Bundles expose service implementations; they do not provide arbitrary classes to be used by other bundles.
Bundles should expose service implementations: This is the corollary to the previous rule. Bundles should not be created when arbitrary concrete classes are being extracted to a library. In that case, a library/jar is the appropriate module packaging type.
Bundles should generally only export service packages: If there are packages internal to a bundle that comprise its implementation but not its public manifestation of the API, they should be excluded from export and kept as private packages.
Concrete objects that are not loaded by the root classloader should not be passed in or out of a bundle: This is a general rule with some exceptions (JAXB generated classes being the most prominent example). Where complex objects need to be passed in or out of a service method, an interface should be defined in the API bundle.

Bundles separate contract from implementation and allow for modularized development and deployment of functionality. For that to be effective, they must be defined and used correctly so inadvertent coupling does not occur. Good bundle definition and usage leads to a more flexible environment.

27.2.1.1.2. Maven Bundle Plugin

27.2.1.2. Third Party and Utility Bundles

It is recommended to avoid building directly on included third party and utility bundles. These components do provide utility and reuse potential; however, they may be upgraded or even replaced at anytime as bug fixes and new capabilities dictate. For example, web services may be built using CXF. However, the distributions frequently upgrade CXF between releases to take advantage of new features. If building on these components, be aware of the version upgrades with each distribution release.

Instead, component developers should package and deliver their own dependencies to ensure future compatibility. For example, if re-using a bundle, the specific bundle version that you are depending on should be included in your packaged release, and the proper versions should be referenced in your bundle(s).

27.2.1.3. Deploying a Bundle

A bundle is typically installed in one of two ways:

Installed as a feature
Hot deployed in the /deploy directory

The fastest way to deploy a created bundle during development is to copy it to the /deploy directory of a running DDF. This directory checks for new bundles and deploys them immediately. According to Karaf documentation, "Karaf supports hot deployment of OSGi bundles by monitoring JAR files inside the [home]/deploy directory. Each time a JAR is copied in this folder, it will be installed inside the runtime. It can be updated or deleted and changes will be handled automatically. In addition, Karaf also supports exploded bundles and custom deployers (Blueprint and Spring DM are included by default)." Once deployed, the bundle should come up in the Active state, if all of the dependencies were properly met. When this occurs, the service is available to be used.

27.2.1.4. Verifying Bundle State

To verify if a bundle is deployed and running, go to the running command console and view the status.

Execute the list command.
If the name of the bundle is known, the list command can be piped to the grep command to quickly find the bundle.

The example below shows how to verify if a Client is deployed and running.

Verifying with grep

ddf@local>list | grep -i example
[ 162] [Active    ] [       ] [  ] [ 80] DDF :: Registry :: example Client (2.0.0)

The state is Active, indicating that the bundle is ready for program execution.

27.3. High Availability Guidance

Capabilities that need to function in a Highly Available Cluster should have one of the two below properties.

Stateless: Stateless capabilities will function in an Highly Available Cluster because no synchronization between DDF nodes is necessary.
Common storage: If a capability must store data or share state with another node, then the data or shared state must be accessible to all nodes in the Highly Available Cluster. For example, the Catalog’s storage provider must be accessible to all DDF nodes.

The `pollIntervalMinutes` should not be set to value a which results in an unacceptable maximum delay.	1	true

B.3. GeoWebCache Application Reference

GeoWebCache enables a server providing a map tile cache and tile service aggregation.

Warning

The GeoWebCache application is currently in an EXPERIMENTAL status and should not be installed on a security-hardened installation.

GeoWebCache enables a server providing a tile cache and tile service aggregation. See (GeoWebCache ) for more information. This application also provides an administrative plugin for the management of GeoWebCached layers. GeoWebCache also provides a user interface for previewing, truncating, or seeding layers at https://{FQDN}:{PORT}/geowebcache/.

B.3.1. GeoWebCache Application Prerequisites

None.

B.3.2. Installing GeoWebCache

Install the GeoWebCache application through the Admin Console.

Navigate to the Admin Console.
Select the System tab.
Select the Features tab.
Install the geowebcache-app feature.

B.3.3. Configuring GeoWebCache

GeoWebCache can be configured to cache layers locally, using the following procedures.

B.3.3.1. Adding GeoWebCache Layers

Add layers to the local cache:

Navigate to the Admin Console.
Select the GeoWebCache Application.
Select the GeoWebCache Layers tab.
Click the Add button.
Enter the data in the fields provided.
If necessary, click the Add button to add additional MIME types.
If necessary, click the Add button to add additional WMS Layer Names.

Table 145. Add Layer
Name	Type	Description
Name	String	Unique name assigned.
Mime Formats	String	List of mime formats used.
URL	URI	URL location of layer to add.
WMS Layer Name	String	The name(s) of WMS layers that exist at the URL specified above. If no WMS Layer names are specified, GeoWebCache will look for the Layer Name specified in the name field. Otherwise, it will attempt to find all layer names added here and combine them into one layer.

B.3.3.2. Editing GeoWebCache Layers

Navigate to the Admin Console.
Select the GeoWebCache application.
Navigate to the GeoWebCache Layers tab.
Click the Name field of the layer to edit.

B.3.3.3. Removing GeoWebCache Layers

Click the Delete icon at the end of the row of the layer to be deleted.

B.3.3.4. Configuring GWC Disk Quota

Storage usage for a GeoWebCache server is managed by a diskquota.xml file with configuration details to prevent image-intensive data from filling the available storage.

To view the disk quota XML representative: https://{FQDN}:{PORT}/geowebcache/rest/diskquota.xml

To update the disk quota, a client can post a new XML configuration: curl -v -k -XPUT -H "Content-type: text/xml" -d @diskquota.xml "https://{FQDN}:{PORT}/geowebcache/rest/diskquota.xml"

Enter configuration for Imagery Provider in new textbox:
{"type" "WMS" "url" "https://{FQDN}:{PORT}/geowebcache/service/wms" "layers" ["states"] "parameters" {"FORMAT" "image/png"} "alpha" 0.5}
Set the Map Projection to EPSG:900913 or EPSG:4326. (GeoWebCache supports either of these projections.)

Note

Currently, GeoWebCache only supports WMS 1.1.1 and below. If the version number is not specified in the imagery provider, DDF will default to version 1.3.0, and OpenLayers will not project the image tiles properly. Thus, the version 1.1.1 must be specified when using EPSG:4326 projections.

{"type" "WMS" "url" "https://{FQDN}:{PORT}/geowebcache/service/wms" "layers" ["states"] "parameters" {"FORMAT" "image/png" "VERSION" "1.1.1"} "alpha" 0.5}

B.9. Spatial Application Reference

The Spatial Application provides KML transformer and a KML network link endpoint that allows a user to generate a View-based KML Query Results Network Link.

B.9.1. Offline Gazetteer Service

In the Spatial Application, the offline-gazetteer is installed by default. This feature enables you to use an offline source of GeoNames data (as an alternative to the GeoNames Web service enabled by the webservice-gazetteer feature) to perform searches via the gazetteer search box in the Search UI.

By default a small set of GeoNames data is included with the offline gazetteer. The GeoNames data is stored as metacards in the core catalog and are tagged with geonames and gazetteer. This collection of GeoNames metacards can be expanded or updated by using the gazetteer:update command.

B.9.1.1. Spatial Gazetteer Console Commands

The gazetteer commands provide the ability to interact with the local GeoNames metacard collection in the core catalog. These GeoNames metacards are used by the offline-gazetteer feature, which is an optional feature available in this application and is explained above. Note that these commands are only available if the offline-gazetteer feature is installed.

Table 180. Gazetteer Command Descriptions
Command	Description
`gazetteer:update`	Adds new gazetteer metacards to the core catalog from a resource. The resource argument can be one of three types: a local file path to a `.txt`, `.zip`, or `.geo.json` GeoNames data file. If a path to a file ends in .geo.json, it will processed as a geoJSON feature collection and imported as supplementary shape data for GeoNames entries. a URL to a `.txt` or `.zip` GeoNames data file. GeoJSON URLs are not supported. a keyword to automatically process a GeoNames file from from http://download.geonames.org/export/dump. Valid keywords include a country code, which will add the country as GeoNames metacards in the core catalog. The full list of country codes available can be found in http://download.geonames.org/export/dump/countryInfo.txt. `cities1000`, `cities5000`, and `cities15000`, which will add cities to the index that have at least 1000, 5000, or 15000 people, respectively. `all`, which will download all of the current country codes. This process may take some time. The `-c` or `--create` flag can be used to clear out the existing gazetteer metacards before adding new entries.
`build-suggester-index`	Builds the Solr suggester index used for placename autocompletion in Intrigue when using the offline gazetteer. This index is built automatically whenever gazetteer metacards are created, updated, or deleted, but if those builds fail then this command can be used to attempt to build the index again.

Appendix C: Application Whitelists

Within each DDF application, certain packages are exported for use by third parties.

C.1. Packages Removed From Whitelist

In the transition of the whitelist from the ambiguous package listing to the new class listing several errors were found. The packages originally listed that were removed either did not exist, contained experimental interfaces, or contained only internal implementations and should have never been included in the whitelist. The following is a list of packages that were listed in error and have been removed from the whitelist.

Note	None of the packages in this list have been removed from the distribution. They may however be changed or removed in the future.

Appendix E: Hardening Checklist

The following list enumerates the required mitigations needed for hardening. It is not intended to be a step-by-step procedure. To harden a new system, perform configuration as documented.

❏ Configure Auditing
❏ Set Directory Permissions
❏ Configure Keystore and Certificates
❏ Disallow Login Without Certificates
❏ Configure Certificate Revocation
- ❏ Deny Guest User Access (if denying Guest users)
- ❏ Allow Guest User Access (if allowing Guest users)
❏ Configure Guest Claim Attributes (if allowing Guest users)
❏ Configure Guest User Authentication
❏ Create unique user role
❏ Limit Access to the STS
❏ Restricting Access to Admin Console
❏ Restrict Feature, App, Service, and Configuration Access
❏ Remove Default Users
❏ Harden Solr
❏ Environment Hardening
❏ Isolate Solr Cloud and Zookeeper. (If using)

Appendix F: Metadata Reference

DDF extracts basic metadata from the resources ingested. Many file types contain additional file format-specific metadata attributes. A neutral Catalog Taxonomy enables transformation of metadata to other formats. See also a list of all formats supported for ingest.

F.1. Common Metadata Attributes

DDF supports a wide variety of file types and data types for ingest. The DDF’s internal Input Transformers extract the necessary data into a generalized format. DDF supports ingest of many datatypes and commonly used file formats, such as Microsoft office products: Word documents, Excel spreadsheets, and PowerPoint presentations as well as .pdf files, GeoJson and others. See complete list. Many of these file types support additional file format-specific attributes from which additional metadata can be extracted.

Note	These attributes will be available in all the specified file formats; however, values will only be present if present in the original document/resource.

These attributes are supported by any file type ingested into DDF:

Common Attributes in All Supported File Types

metadata
id
modified (date)
title (filename)
metadata content type (mime type)
effective (date)
created (date)

These 'media' file types have support for additional attributes to be available when ingested into DDF:

File Types Supporting Additional Attributes

Video Types
- WMV
- AVI
- MP4
- MOV
- h.264 MPEG2
Image Types
- JPEG-2000
Document Types
- .DOC, .DOCX, .DOTX, .DOCM
- .PPT, .PPTX
- .XLS, .XLSX
- .PDF

These are the attributes common to any of the media file types which support additional attributes:

Additional Possible Attributes Common to 'Media' File Types

media.format-version
media.format
media.bit-rate
media.bits-per-sample
media.compression
media.encoding
media.frame-center
media.frame-rate
media.height-pixels
media.number-of-bands
media.scanning-mode
media.type
media.duration
media.page-count
datatype
description
contact.point-of-contact-name
contact.contributor-name
contact.creator-name
contact.publisher-name
contact.point-of-contact-phone
topic.keyword

F.2. File Format-specific Attributes

Many file formats support additional metadata attributes that DDF is able to extract and make discoverable.

F.2.1. Mp4 Additional Attribute

Mp4 files have an additional attribute:

ext.mp4.audio-sample-rate

F.2.2. All File Formats Supported

Supported File Types

Using the various input transformers, DDF supports ingest of the following MIME types. While ingest is possible for these files, metadata will be limited unless otherwise noted.
