DAML-S 0.7 now available

A new version, version 0.7, of DAML-S (DARPA Agent Markup Language for
Services) is now available at http://www.daml.org/services/.  DAML-S is
a DAML+OIL-based Web service ontology, which supplies Web service
providers with a core set of markup language constructs for describing
the properties and capabilities of their Web services in unambiguous,
computer-intepretable form.  DAML-S also provides service requesters
with semantic constructs to describe the functionality and constraints
of services desired by a requester.  Version 0.7 introduces the
Grounding ontology, and also includes substantial refinements to the
Profile and Process Model ontologies.  In addition, a new example of a
Profile-based (yellow-pages style) service taxonomy is presented, and
the existing service examples have been made more complete.

The services ontology includes three major subdivisions, those dealing
with profiles, process models, and groundings.  Roughly speaking, a
service profile describes "what the service does", for purposes such as
advertisement, discovery, and matchmaking; a process model describes
"how the service works", for uses such as automatic invocation,
composition, and monitoring of services; and a grounding provides the
details of "how to access the service".
The new Grounding ontology ties DAML-S in with the Web Services
Description Language (WSDL), an emerging, collaborative industry effort
that is currently the focus of a W3C working group.

As noted on the release home page, feedback is welcome from
all interested parties, through the www-ws@w3.org email list.
