WS-Addressing Reference Parameters are still there so they could be used instead of Reference Properties. It's just that the semantics have changed now. Also, I don't think that this was a result of my efforts. It was mostly the Web folks. Regards, -- Savas Parastatidis http://savas.parastatidis.name =20

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. =20 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. =20 I dont know what the implications for the WSDL are, =20 -Steve =20 =20 =20
