Element Definitions (DRAFT)

Duration:  Time-based extent (playback time) of the resource

  • May refer to an resource as a whole or to the various parts that make up a resource
  • Does not describe the time to utilize a resource in a setting
  • Represented as a timestamp
  • Required
  • ebucore:duration

Start Time: beginning point of playback for a time-based resource

  • Required if part of a larger resource
  • Used in combination with Duration to identify a segment of a resource
  • Represented as a timestamp

End Time (is this needed if using duration and start time?) 

  • Required if part of a larger resource

Number of Parts: the number of segments that combine to create the resource as a whole

  •  Used in conjunction with <has part>
  • Represented by a whole number
  • Required if a resource is made up of multiple segments
  • Segments could be tracks, chapters, scene, shot, etc.

Part Number: indicates which numbered part a segment is of a given resource

  • Used in conjunction with <is part of>
  • Required if a resource is a segment of a larger resource
  • Examples: 1 of 5; 2 of 2; 7 of 9

Transcription/Subtitles/Captions:

  • Similar to PB Core annotation element?
  • Or relation field that points to additional files?

Part and number of parts – description fields? Relation fields?  Identifier fields? Not sure.

Key Frame / Thumbnail

  • An image that is representative of the audio/video resource.

Video Compression Method

  • The method by which a video bitstream is encoded for transmission and decoded for use.

Video Resolution

  • The number of pixels in the horizontal and vertical dimensions of the video.

Video Frame Rate

  • The number of frames per second at which the video source item was digitized.

Video Bit Depth

  • The number of bits of information stored for each sample taken during the quantization of an analogue signal.
  • No labels
