Interesting development over in W3C land: WS-Addressing no longer has reference properties, thanks to the unrelenting efforts of Savas-the-subversive, and others: http://www.w3.org/2002/ws/addr/wd-issues/#i001 This is interesting because the current "modeling stateful resources with web services" paper says "a WS-Resource qualified endpoint puts its state identifier in the wsa:ReferenceProperties element". Now it can't; the state identifier has to be encoded in the URL itself, as with classic stateful URLs like IMdB movie links, RDF identifiers, etc, etc. So wsa is more aligned with W3C and less with WSRF. This is not really our problem, we just have to make sure that we use terms like "WS-Resource qualified endpoint" without specifying what that exactly that means, and wait for the WS-RF definitions to catch up. It actually has a nice side-effect operations wise; as all EPRs are now just URLs, you can always paste the URL into a web browser and get a status page, 404 error, whatever -but something that is good when fielding remote bug reports. I dont know what the implications for the WSDL are, -Steve
