use case clarification - cross format annotations

Paolo

Thanks for providing a use case on the wiki - https://www.w3.org/annotation/wiki/Cross-formats_Annotations

I think what you are saying is that the same document can be provided in different formats (e.g. HTML or PDF) at different portals (e.g. PubMed Central vs authors personal web site etc) - I guess different portals could also offer the same format with different URLs as well.

The use case also says that sometimes these various targets should be treated as the same despite having different URLs and sometimes should be treated as different, depending on user choice.

Thus I have  questions

- how can a system know that two documents are different representations of the same document when they have different URLs?

- why would a end-user want only to provide annotations for a specific representation of the same target and not have it apply to all versions?

- should we simplify the use case to how to share annotations for a target that has multiple instances with different URLs.

It seems the big issue here is that different URLs might refer to the same target, and how to handle that.

I know I’m jumping ahead, but thought I’d ask now.

regards, Frederick
