The technical specification: R. Akkiraju, J. Farrell, J.Miller, M. Nagarajan, M. Schmidt, A. Sheth, K. Verma (in alphabetical order), "Web Service Semantics - WSDL-S, " A joint UGA-IBM Technical Note, version 1.0, April 18, 2005 is available at IBM and UGA sites: 1) http://lsdis.cs.uga.edu/projects/meteor-s/wsdl-s/ 2) http://www.alphaworks.ibm.com/g/g.nsf/img/semanticsdocs/$file/wssemantic_ann... WSDL-S was also presented at the W3C Workshop on Frameworks for Semantics in Web Services. The presentation made at the workshop, which also identified its driving principles consistent with evolutionary approach that preserves current investments in SOA, is available at http://lsdis.cs.uga.edu/projects/meteor-s/wsdl-s/WSDL-S.pdf. WSDL-S supports adding semantics to WSDL by using its extensibility capabilities. The key annotations supported are: *Annotating message types (XSD complex types and elements) -extension attribute : modelReference (semantic association) -extension attribute : schemaMapping (schema/data mapping) * Annotating operations -extension elements : precondition and effect -extension attribute : category (on the interface element) -extension element : action (on operation element)(under consideration) We invite comments, suggestions and questions from interested parties at the public forum: http://lsdis.cs.uga.edu/forum/viewforum.php?f=13 Tool support for WSDL-S is avaiable at: METEOR-S Downloads: http://lsdis.cs.uga.edu/projects/meteor-s/downloads/ alphaWorks ETTK: http://www.alphaworks.ibm.com/tech/wssem Thanks, Kunal Verma (for the METEOR-S team) http://lsdis.cs.uga.edu/~kunal
