Limit playback to selected time segment in structured navigation

[elynema]

Description

With the migration of EVIADA content into MCO, Avalon has a use case for having playback based on the structured navigation terminate after the time segment completes playback.

In this case, if the user clicked on a heading in the structured navigation, playback should stop once that time segment completes playing. If the user clicked on a heading that has children, playback should continue through the children time segments and then stop once the parent time segment is completed.

Done Looks Like

• Is this possible within IIIF?
• Model what this manifest would like like
• If we support this, does it break Ramp for other IIIF use cases?
• Would Ramp default to auto-play?
• Would it be strange for Ramp to work this way for EVIADA materials but different for other collections?

The IIIF behavior property on ranges might be the way to implement this. Attributes on ranges would indicate to the viewer that only a specific portion of the full media should be presented to the user. There are probably a lot of tricky edge cases involved here.

Putting in options to remove default autoadvance etc. for collection managers could be a motivation to have SME handle IIIF ranges and structures more ably. SME creates structure data from manifests, and then uses that structure to update the manifest. In terms of evolution of SME, having the ability to create more flexible structures (like allowing for arbitrary nesting, as is common in IIIF).

We could model some IIIF structure in advance, and then build the desired UX around that.

Would be a good swarm topic: discussing IIIF structures and what they'd look like.
