If I misstate the following, anyone feel free to correct me. I agree with you, Uche, but some background follows.

Because it is an issue that resurfaces again and again with respect to the definition of what a "resource" is. Apparently in the RDF formal definitions, it doesn't work because RDF or KR needs a stricter one to one mapping and URIs don't formally provide that for tangible objects: just resources. I agree with what you are saying but there exists definitional or formal confusion. The TAG has been doing another round on this one. It comes down to unique identification of a "resource" where a resource is "anything with identity" but resource is a term for a concept, and that concept braces representations. At the end, the URI is naming a concept, not an object. This works because the implementors understand that and where they see "resource" they use, as Joshua Allen says, a "hypertext dispenser" or one might say, a representation dispenser. The question becomes, who should fix what? Empirically, the URIs on the web work and implementors do the right thing. In RDF, that does not seem to sufficient and then the argument becomes, what if anything should the RDF spec team fix in their specification? I've no skinny in this game, but the arguments are very intriguing to follow. len
