No, Namespaces still provide a facility for universal names; that said, the provision of a facility is easy, while the process of getting people to agree to a single set of names is *very* hard. For example, I can declare that (using James Clark's notation) {http://www.megginson.com/ns/}person names an element or attribute referring a person; at the same time, Amazom.com can declare that {urn:urn-12345:ns}human names an element or attribute referring to a person. One can hardly claim in any fairness that this is a breakdown in Namespaces -- it's a business problem that (with any scheme) can be solved only by the long, laborious process of discussion, trial implementation, and standardization. Exactly the same problem could occur with Architectural Forms or any other mechanism for naming or subtyping. > If both Microsoft and W3C have major applications that tie namespace > names to particular technologies, then we do not have the nice layers > that Dave sees: we have one layer limiting the previous layer. Not at all -- Namespaces provide a universal naming layer, and RDF and BizTalk present (incompatible) application-specific mechanisms for using that information. It might be nice to standardize higher layers, but we'll have to see how things develop.
