AV Annotations TSG


Members from the IIIF A/V Community Group would like to propose a mechanism to more explicitly identify the nature of annotations in the IIIF Presentation API. The current IIIF Presentation API 3.0 and Web Annotation motivations do not provide clear, reliable mechanisms to inform IIIF clients how to distinguish between and present to the user annotations that represent transcripts, captions, and subtitles.

The scope of the work to be performed by the AV Annotations TSG will be limited to addressing the use cases related to transcriptions, captions, and subtitles, and translations of those items.

The group charter specifies the deliverables and aims of the group in more detail.
