Subject: RE: [wsrf] Comments on wsrf-ws_resource-1.2-spec-wd-07
One reason it is now difficult to relate the terms "resource identifier" and "reference to a WS-Resource" is that I removed (per the resolution to issue 127) the following text which related these 2 concepts: "An identifier of the resource MUST be represented in any reference to a WS-Resource. and MUST appear as part of any message to a WS-Resource to allow the WS-Resource to disambiguate the resource targeted by the message. The precise location of the resource identifier in a message to a WS-Resource is dependent on the protocol binding used to interact with the WS-Resource endpoint but is normatively defined in the appropriate WS-Addressing binding specification. For example, [WSA – SOAP] defines the binding of message addressing properties for the SOAP protocol." It is not clear to me that this text repeats any part of WS-Addressing - it is a description of the WS-RF usage of EPRs. I would agree with Kirk's observation and suggest that we reinstate some or all of the above text. At the very least, it would seem that we should still state: "An identifier of the resource MUST be represented in any reference to a WS-Resource. " Comments?

An EPR is only a reference to a resource. The use and rules associated with reference parameters is covered in WS-Addressing and should not be covered in this spec.

Obviously, SomeDisabmiguator is part of the reference to a WS-Resource (ReferenceParameters). Further, I assume, after carefully trying to connect things that are in the text, that the Resource Identifier is at least one possible "disambiguator element". If so, would be clearer to use <ResourceIdentifier>R1</ResourceIdentifier> rather than <SomeDisambiguatorElement> in the example? After all, the text does say that "R1" "identifies" the resource Kirk Wilson Architect, Development Office of the CTO 802 765-4337
