Ugo, for one, as Stephen suggests the OWL formalization can be used as an
upper ontology for the work of groups such as the OWL-S coalition or the
Semantic Web Services Language committee (SWSL) and Semantic Web Services
Architecture committee (SWSA). The upper OWL ontology could be further
specialized by these groups, constraints could be added etc. In a long term
view, one could imagine that if a new spec for example were to be expressed
in such an ontology, then inferences about compliance of the new spec with
the architecture could be inferred.
 Cheers, Katia

What I have not been able to figure out so far is the "then what?" part.
In other words, what is the goal for the OWL formalization of WSA
(besides being a showcase of semantic technologies)? Is there a plan to
do anything with that formalization? What kind of results would you like
to achieve once you apply a reasoning engine to that information?
