Subject: Re: [wsrf] WS-Addressing submitted to W3C as input
Good question. But taking a step back, I am not sure what EPR is trying to do -- is it trying to provide a referencing mechanism for a Web service/endpoint or provide such a reference with additional bag of coordination/context related data. Both seem like a useful thing to do, but my concern is that EPR construct does not provide a clear separation of the two. I.e., provide a referencing mechanisms at the base layer and build on it by providing a way to including coordination/context related data (thru ref properties/ref parameters). It seems like architecturally it makes sense to separate the two. -Anish -- Savas Parastatidis wrote: > All, > > > > How do the changes in the submitted version of WS-Addressing affect > WS-RF?
