> Is it really possible to make RDF useless with just changing > the meaning of namespace URI Certain parts of the RDF Model and Syntax rely on using properties as attached to the end of namespaces. That is to say: <Description xmlns="http://www.w3.org/1999/02/22-rdf-syntax-ns#"/> Refers to this RDF property:- http://www.w3.org/1999/02/22-rdf-syntax-ns#Description Of course, RDF parsers already understand that, but I could write a Schema that is more explicit than that, and it would have to look it up. > If yes - you should see how *huge* is the power of this URI. > It can make RDF useless overnight. Nah, because it wouldn't change. No-one is going to forbid anyone from dereferencing a namespace (just as it is unwise to make it mandatory). > Namespaces shouldn't be dereferenced until theere is a > clear understanding *how* should they be dereferenced. In a system x1, dereference the namespace accoroding to the specification x2. In an RDF system, dereference the ns and parse it as an RDF Schema. How is that not clear? > There is no such understanding now, and at the > same time the spec allows anybody to dereference > namespaces in *any* way - and this dereferencing > will be conformant == blessed by W3C. True (or more accurately: I agree). If I understand what you are saying there... > I don't understand. I'm not saying that URIs > should be URLs.

It's fine saying that, but I can't debate it if there isn't a reason behind that proposition :-) IOW: Why should no-one ever dereference ns'? > PS. So *you* think URI points to RDF ? Only in an RDF system. Well, even then it doesn't have to... there are some "freak" cases that I have seen, like using mailboxes to define people. > I think those who really like RDF can bind their documents > to RDF with some other mechanisms. Right? Maybe, but what hassle! Kindest Regards, Sean B. Palmer http://infomesh.net/sbp/ http://www.w3.org/WAI/ [ERT/GL/PF] "Perhaps, but let's not get bogged down in semantics." - Homer J.
