Background and Summary

This recipe provides a complex canvas with a video, images and text which are painted on a timeline. It provides a complex use case to test whether viewers can cope with some of the extended posibilities provided by the Presentation API.

I've had a positive experience with the Theseus Viewer, and the JSON-LD serialization looks fine to me.

However, this recipe really shows the limitations of cross-client interoperability. In viewers or players outside of Theseus, the experience is notably poor. I'm wondering if it would be beneficial to include a warning in the Manifest to alert users to these potential issues when IIIF clients that do not - or only partially - support it.

👍 I made a small note about the duration property in hypothes.is

We had some discussion on the call about the title and how it's somehow not quite right. The use case is an imaginary teaching scenario, but the recipe is definitely not just about teaching.

Standard comment that I upvoted my own recipe

Giving a thumbs up, but conditional on a few changes from editors:

• In the implementation notes: "Once there is an AV resource included on a Canvas, there exists a notional timeline whose duration and time range can then be used in targeting resources to the Canvas." This isn't quite accurate. The duration/timeline exists because it is defined in the Canvas and is technically not dependent on having an AV resource. Can you change the language to reflect that the Canvas duration property is what introduces the timeline feature/functionality?
• Remove the teaching bits from the title/recipe and rename something like "Rendering multiple media types on a time-based Canvas"

It would also be nice to eventually have two additional recipes for 1) using duration on a Canvas to introduce resources on a timeline and 2) painting an annotation (textual body) onto a canvas. This recipe could be updated later to reference these, but doesn't need to wait for these (and are just suggestions).

Also +1 with the caveats above from Dawn. It's a valuable recipe from the point of view of an "integration test" -- here is how you can put multiple things together on a single temporal canvas, some of which are not themselves temporal. That to me is the functionality that sets this recipe apart from others.

In addition to other issues mentioned there is an "in in" in:

When resources’ appearance on a Manifest are governed in part by time, they can be entered in in the Manifest in any order.

I think this is confusingly written (and first Manifest should be Canvas). I suggest instead:

The order in which resources appear on the Canvas is governed by the time portion of the annotation target when specified, they can be entered in the Manifest in any order.
