Web Services versus Semantic Web Services.

Hi,

I am very pleased to see that this mailing list is (at last) created
within W3C !

I truly believe that web services (real) interoperability can only be
reached only if web services are described semantically. 
The current trend in web services arena defines the web services using
different standards based on XML schemas (UDDI, ebXML,WSDL, SOAP,
SAML,XXX,XXXX...).
IMHO, the huge number of XML schemas to deal with, makes the integration
of exiting web services very hard, costly, very brittle and hard to
evolve. 
I favor a more loosy coupled architecture, based on a minimal design,
that is not based on structure and syntax (such as XML Schema) but
rather on semantic information exchange (RDF/OWL). 
I wish to see in the future more focus on systematic mapping of the
different standards such as WDSL, BPEL to RDF/OWL.  

I see two important aspect that needs to be standardized:

- A core ontology for describing Web Services (such as DAML-S)
- A standard ( universal ?) semantic query language based on RDF
(support of graph pattern/ filter/ rules / bindings).

I have not seen so much activity on DAML-S recently ? Will W3C try to
standardize DAML-S (OWL-S??)
What is going on the semantic query language side ?

I am curious to get your opinions on my thoughts...
