Group Documents

Categorized documents pulling information from Slack channel discussions and elsewhere. A good resource for reviewing recent meeting notes, project roadmaps, implementation helpers, and sample materials.

Presently IIIF A/V's two main areas of focus are:

  • Providing access to the bitstreams of the audio and video content.
  • Integration with and extension of the existing Presentation API to accommodate its appropriate rendering.

The Audio and Video Content APIs will mirror the existing Image API in function - they provide interoperable access to temporal and spatial segmentation and transformation of the content to enable its use and reuse in multiple contexts.

This has the same division as the Image API between access to the bits and a JSON-LD description of the features provided by the service.

Issues/Ideas about implementing IIIF A/V in Avalon/Hyrax

Client Side

  • Select/utilize an accessible, universally supported media player which can consume IIIF A/V's manifest.
  • Identify new use cases benefiting from expanded/altered manifest information.
  • Identify data items in updated manifest object which may break current player implementation.
