Thanks for this. I would also be interested in people's views and experience of the orthogonality of these things. WSRF grew from OGSI, which attracted much discussion over its so-called "stateful services" - some saw these as denying some of the benefits of the web services model. In WSRF there was a shift to a resource perspective in which services provide access to state. One question is, does this state issue have any impact at all on the use of OWL-S (e.g. in describing service composition), or are these things orthogonal as suggested? I believe that in principle WSRF services can be described with sufficient expressivity in OWL-S, but it would be interesting to see someone apply OWL-S to some "real" WSRF services in order to get some insight into this in an application context.
