RE: Overloaded URIs must GO!
Hi Paul Paul said: It is now both legal and appropriate for us to propose the hname: namespace which is defined to mirror the HTTP namespace (in terms of ownership and uniqueness) but be a URN instead of a URL and thus explicitly unretrievable. In the meantime, it seems that we can use an experimental namespace: "x-hname" and take our chances that nobody somewhere else on the Web will use the same name incompatibly. Didier says: We got a lot of dicussion on this subject in the IETF group and got at first the suggestion to register all name spaces at IANA. Most of us thought that this is however insuficient and a more formal registration mechanism would be needed (This still an open issue). If W3C needs a mechanism to resolve URNs this can be done through DNS And a client able to resolve the right DNS record (as you know there is more than just IP address records in DNS). W3C could maintain the DNS able to resolve the name space you mentioned and a client would then need to use the right DNS record to obtain the URL. The actual URN name resolution (Daniel Laliberte worked on this) returns one or more URL so that now you can get the needed document with one of the existing protocols.The good point here is that the DNS server act also as a repository. The client would have to connect to the W3C DNS server and for quality of function have a backup server somewhere else. This would be superor to a single URL resolution (if the server is down, Kaput :-) Regards Didier PH Martin mailto:martind@n... http://www.netfolder.com xml-dev: A list for W3C XML Developers.
