So this supports my hunch that what we all need for a further technological
step is to start adding the semantics, via say RDF, etc, to the basic WSDL
and XSD of web services. This ties the semantics more firmly to the syntax.
It then obliges service consumers to 'understand' (both in the human, and
hopefully also in the machine processing sense) the semantics when using
the syntax. It also will, hopefully, maximize the visibility of both changes
to semantics and to syntax/structure. Isn't this a natural extension of the
semantic web/Web 3.0 principles and in a very worthwhile direction? More
intelligent web services?
