Yah, that was my contribution you quoted there. 8-)
Unfortunately, it's not as simple as that. Web Services and the Semantic Web are two ways of addressing basically the same problem; machine automation. But only one reuses Web architecture/REST.
I wonder if Roy Fielding would agree with your radical dualism.
see
"In order for SOAP-ng to succeed as a Web protocol, it needs to start
behaving like it is part of the Web. That means, among other things,
that it should stop trying to encapsulate all sorts of actions under
an object-specific interface. It needs to limit its object-specific
behavior to those situations in which object-specific behavior is
actually desirable. If it does not do so, then it is not using URI
as the basis for resource identification, and therefore it is
no more part of the Web than SMTP."
Yes, thanks. I've been the principle supporter of REST principles within the XML Protocol WG. SOAP 1.2 is REST compatible in large part because of my contributions.
