DAML and WSDL

Hi All

From the information that I’ve gathered up to now, it seems that there is no
work that is integrating the industrial effort that brought about SOAP, WSDL
and UDDI and the semantic web. In my opinion these works should complement
each other. The semantic web with the standardized RDF/XML and its
derivatives, such as RDFS and DAML+OIL would definitely increase the
expressiveness in describing web services, as stated in [1]. Uche Ogbuji in
his paper [2] described how to combine RDF with WSDL to obtain a graphical
representation of the web service definition. There was also some work done
by Henrik Frystyk Nielsen gives examples at [3] of how RDF can be serialized
in a SOAP message.
I ask why has there been such a small effort in the integration of such
work? There doesn’t seem to be a limitation from the DAML+OIL point of view,
on the contrary, this would increase the expressiveness. Am I right?

I don’t know if the recently created WebOnt group is going to indulge in
such consideration when the new web ontology language is created, but in my
humble opinion this should be the way.

If someone has other knowledge on related work please update me.
