Dear Charlie,

Good questions!  There are indeed plans to use OWL as the bases for 
a WS description language, and another initiative in the works that
is relevant to you.

As you note, DAML-S, an ontology for Web service description, is
currently described using the DAML+OIL ontology language.  DAML-S
version 1.0 is currently in the works, and there is a strong possibility
that it will be released in OWL.  As you know, OWL took DAML+OIL as
its starting point, and it has always been the intention of the DAML
Services Coalition (the creators of DAML-S) to transition DAML-S from 
DAML+OIL to OWL, once OWL was defined and stable.

More generally, a new joint DAML-North American-European Semantic
Web Service Initiative is currently in the works that will see
the continuation of efforts at building a Web Service Descriptoin
Language (as well as an architecture) that exploits richer representation
of services, and that builds on emerging industry initiatives such
as BPEL4WS, XLANG, WSFL, WSCL, WSCI, etc.  At this early stage, it
certainly appears that ontological aspects of this language will 
be developed in OWL.  Further details of this initiative will be posted 
to relavent lists in the coming months.

Regards,
Sheila McIlraith
