As I understand RDF, there is a dichotomy between both, then your examples are clearly different. Though, it would be very interesting to do (2). Some people on this thread talked about 'dereferencing', but I don't quite agree with teir view : I don't think we NEED to dereference, for example, an RDF file's URI to its RDF content : RDF statements are about resources, and the resource IS the content, am I wrong ? So your problem depends on the semantic behind that '#' symbol (fragment) which, according to URI specifications, depends on the mime-type of the resource. For RDF, clearly, it denotes a "virtual" resource, defined inside the "real" RDF file resource. For HTML, since it is only used (curently) with <a name=...> syntax, it denotes a point in the file, but we could imagine to use it with <span name=...> as Ora Lassila suggests... For JPEG or other binary format containing legacy meta-data, we could imagine using '#' notation to access them... Why not ? The remaining (and not that easy !) problem is that, as far as I know, when you request a #'ed URL to an http server, it returns the whole resource, so it's YOUR job to extract the fragment. But isn't it the philosophy of XML and RDF : "may be I don't understand the whole stuff, but I still can do things with it" Specialized application will handle certain kind of resources, knowing things about their mime-types, and how extracting fragment from them. Hope this'll help Pierre-Antoine
