Gallery API use cases?

Hi,

I looked at the Gallery API and noticed that it is still a bit unclear to me from where the requirements are derived from and whether they are meaningful:

  http://dev.w3.org/2009/dap/gallery/#requirements
  http://www.w3.org/TR/2009/NOTE-dap-api-reqs-20091015/#gallery

In order to move the spec forward, I guess it would help if we could come up with a set of sensible use cases, similarly to:

  http://dev.w3.org/2009/dap/file-system/file-dir-sys.html#use-cases

After we agree on the UCs, we could see if ...

- The UCs are fulfilled with what we already have.

- It would make sense to extend the file-dir-sys by defining an entry point to a well-known filesystem area for media and extending the metadata interface with media-specific metadata, among others changes. This would be a headless API with no UI integration.

  http://dev.w3.org/2009/dap/file-system/file-dir-sys.html

- If the Gallery design could align with Contacts, as discussed some months ago. Depending on the use cases we come up with, I could see the merits of e.g. reusing the file picker for finding and filtering media objects.

So, use cases anyone?

(I guess this relates to ACTION-216)
