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