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.
