From: Uche Ogbuji <uche.ogbuji@f...> > Rick Jelliffe says let's cave and allow NSRef == schema. No, what I am saying is this: I (and others, such as Tim Bray, Noah Mendelson and Simon StL) have long been saying namespace!=schema and that W3C needs complete the Namespaces spec with a suitable related-resource discovery language. There should be a single W3C-family way to do this. Where I am moderating my position is in the case where the data provider only has a single resource available. Perhaps you only have an HTML document, or a Schematron Schema, or an RDF Schema or an XML Schema, or RELAX. In that case, the related-resource document is a null layer (and therefore undesirable for the WWW) : it just redirects to a single resource. So in that case, I think simplicity and efficiency both dictate that the null layer be omitted, and the ultimate single resource be directly retrieved from the namespace name. So namespace!=schema. Instead, the namespace resource is always a directory of related resources, but if dereferencing a namespace URIref returns a document that is not a directory of related resources then the directory of related resources can (i.e. must) be *implied*, with no violence to the conceptual model. I think this provides the only way out for us. It is simple, clear, definite, extensible, allow plurality, and removes a roadblock to the semantic web. It also gives us an alternative for use in SOAP, where they want to have namespace=schema. Cheers Rick Jelliffe
