Hi,
I would like to bring your attention to the recently released joint
UGA-IBM technical note on WSDL-S. 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_annotation.pdf
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/
