Subject: RE: [oasis-member-discuss] OASIS namespace documents for URN namespaces
Paul: I think the objective is laudable but I don't see the point of the "http://www.oasis-open.org/namespace?ns=" part of the statement. Surely, if some application wants to do something with the "pure" (and on its own non-deferenceable) urn, then surely it will ba equipped to make that call using http get or whatever. By effectively tying a namespace to a derefereceable network endpoint and to specific and prescribed dereferencing mechanism, is there not a danger that you: - either limit what can be legitimately found at the network endpoint to an RDDL file only, cutting out other possible uses of the namespace; - or creating false expectations and possible architectural problems when unpredictable results come from finding something other than a RDDL document at the end of the pipe. On the other hand, I'd be in favour of a mechanism by which RDDL documents, when available, can be accessed using a prescribed OASIS managed URL to which you would tack the namespace urn.

Some TC's have started using RDDL as a namespace document when these namespace URI's are dereferenced using HTTP GET. Other OASIS TC's use URN's to identify their XML Namespace. I suggest that OASIS provide a mechanism to resolve a namespace document (RDDL or other) using HTTP and passing in the namespace URN in a query parameter. For example, http://www.oasis-open.org/namespace?ns=urn:oasis:names:tc:emergency:EDXL :DE:1.0 would return a RDDL document associated with the EDXL-DE namespace. Paul
