Thanks for this. (04)
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. (05)
