>RFC 2396 says: "A resource can be anything that has identity". Gee thats >helpful in designing tools! :-). Maybe you are looking for something other than a resource.

Resources exist without RDF. It therefore follows that the claim of "there must be constraints [along the lines of RDF]" is false. I'm not saying that RDF isn't useful. It just isn't necessary and has nothing to do with the definition of "what is a resource". Now, if you want to rephrase the question to be a request of "describe the semantics that define this particular resource, using a defined data format for that purpose", then the answer might be RDF. But it sounds more like you want something that lets the origin server tell the client how the representations within a server are mapped to the resources. Good luck. I can think of hundreds of standards, pseudo-standards, and proprietary protocols that might fit within a metaspec that tried to gather together all that is related to URI. Yet another reason why it is a bad idea to even try. However, I believe Leslie means to cover only those URI things that are governed by RFCs, which at least is a tractable problem (even though it was the same problem that sidetracked the old URI WG for over three years). ....Roy
