In [1] the W3C announces the formation of the Web Services Choreography Working Group, the charter for which is at [2]. The charter calls for both a mapping to the Semantic Web: >1.4 Mapping to the Semantic Web > >The Choreography Working Group is strongly encouraged to provide a >semantic mapping using the RDF and OWL technologies. Such a mapping >will allow the information described by the choreography language to >be easily combined with that of other applications. Also, as the >Semantic Web languages allow the application of formal techniques to >the analysis of the meaning of vocabularies, such a mapping would >facilitate the understanding of the choreography language itself. >The Working Group will consider the impact of each of its design >choices on the ability to produce this mapping. > >The goal of the Semantic Web is to enhance the utility of the Web as >a machine-processable information space. The Semantic Web builds on >the current Web infrastructure (XML, URI's, HTTP) and provides a >standardized representation for data (XML/RDF) and for the >conceptual structures behind that data (RDF Schema, Web Ontology >Language). Web services are aiming at enabling automated distributed >computing on the World Wide Web. It is important for both Web >Services and for the Semantic Web that the semantics of the >choreography language be clear and precise. and lists the DAML-S activity as one of those that the group should be coordinating with: >DAML Services >The DAML Services arm of the DAML program is developing a DAML-based >Web Service Ontology (currently named DAML-S), as well as supporting >tools and agent technology to enable automation of services on the >Semantic Web. DAML-S 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-interpretable form. nice to see this growing awareness of the importance of the work being done by DAMLites... -JH [1] http://authors.elsevier.com/JournalDetail.html?PubID=671322&Precis=DESC [2] http://www.w3.org/2003/01/wscwg-charter -- Professor James Hendler hendler@cs.umd.edu Director, Semantic Web and Agent Technologies 301-405-2696 Maryland Information and Network Dynamics Lab. 301-405-6707 (Fax) Univ of Maryland, College Park, MD 20742 240-731-3822 (Cell) http://www.cs.umd.edu/users/hendler
