The W3C has started public discussions on the charter of a new working group. It is called the Semantic Annotations for WSDL working group. It references the WSDL-S spec as an input document to the working group. I have discussed that specification several times on this blog since I am a co-author. There is already a good deal of discussion on the Semantic Web Services Interest Group list. It should be interesting to get the community together to start standardizing this area. This is a fist small step.
