Should we specify it in the recommendation? > What RFC3986 does say about the mime type of a fragment [2]? The mime type is information that is provided by the server through http to the client. It relates to a resource. I wonder what happens if we specify a jpg thumbnail extract from a video through a fragment identifier ... since a fragment only identifies a subresource and not a new resource, we may not be able to do so.

By leaving out the query part, we arrive at the parent resource. Specifying the parent resource should not be a problem for either query or fragment, I would say. > Do we use Link: rel="part_of" <video_uri> as suggested by Yves [3]? I am not even sure we want to do these kind of URIs: http://www.annodex.net/cmmlwiki/OSSForum-Trailer.png?t=0:02:10 They should really be something more like: http://www.annodex.net/cmmlwiki/OSSForum-Trailer.anx?t=0:02:10&type=image/png What do people think?
