Subject:   OWL-S 1.0 release announcement

A new release, version 1.0, of OWL-S (Ontology Web Language for Services) is available here:

http://www.daml.org/services/

OWL-S (formerly DAML-S) is an OWL [1] 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.

This release has been available (unannounced) in Beta form for a couple months, and we appreciate the useful feedback we've received from various reviewers.

Version 1.0 features a number of refinements to the Service Profile and Process Model. The Service Profile is used to concisely represent the service in terms of capabilities, provenance, and operational parameters (e.g., cost-of-use, quality-of-service parameters, etc), for constructing both advertisements and requests. Improvements over DAML-S 0.9 include: clarification and simplification of capability description parameters (i.e., inputs, outputs, preconditions and effects), a tighter integration with the process model, and better organization/modularization of the Profile constructs.

The Process Model provides a declarative description of the processing by which a Web service is realized. Here, the primary improvement over DAML-S 0.9 is a switch in representational strategy: whereas processes were represented as OWL classes before, now they're represented as OWL instances. In addition, the constructs for declaring inputs, outputs, preconditions, and effects have been refined and simplified (and these are now the same as in the Profile).
