A new release of OWL-S, version 1.1, is now available at
   http://www.daml.org/services/owl-s/1.1/
As noted on the release page, we encourage feedback from interested
parties through the public-sws-ig@w3.org email list.

As compared to version 1.0, this release features a good deal of
evolution in the process model (Process.owl), particularly with
respect to the use of variables, the organization of outputs and
effects into conditional bundles called "Results", and the development
of new constructs and practices for expressing conditions,
preconditions and effects.  A new set of constructs is available for
specifying dataflow, and a new control construct ("Perform") is
available to specify service invocation within a composite process.
(Many but not all of these changes have already been available for a
while in the 1.1 Beta release.)  The profile and grounding ontologies
have also seen some changes, although less extensive, and the
documentation has undergone substantial revision.  A summary of other
recent changes is given on the Status page.

The core ontology files and examples are all expressed using valid OWL
DL, and have been validated using tools such as the vOWLidator,
WonderWeb, and Pellet.

OWL-S is an OWL-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. OWL-S markup of Web services facilitates the
automation of Web service tasks, including automated Web service
discovery, execution, composition and interoperation.  OWL-S builds on
the OWL Web Ontology Language Recommendation produced by the
Web-Ontology Working Group at the World Wide Web Consortium.

Previous releases of this language were known as DAML-S, and were built
upon DAML+OIL (the predecessor of OWL).

This release represents work by members of the OWL-S Coalition as well
as much-appreciated help from several interested non-members.
Contributors are listed on the release page.

Regards,
David Martin
