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.

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

These are the attributes common to any of the media file types which support additional attributes:

  • 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

  • description

  • contact.point-of-contact-name

  • contact.contributor-name

  • contact.creator-name

  • contact.publisher-name

  • contact.point-of-contact-phone

  • topic.keyword

File Format-specific Attributes

Many file formats support additional metadata attributes that DDF is able to extract and make discoverable.

Mp4 Additional Attribute

Mp4 files have an additional attribute:

  • ext.mp4.audio-sample-rate

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.
