Their common goal has
focused on the capability of registries to store and publish semantic data, so as to
facilitate the semantic-based description of Web services, the ontology-based categorization
and discovery of Web services, and, therefore, the semantic integration
of business services and applications.
In specific, Moreau, Miles, Papay, Decker, and Payne (2003) present an approach
and implementation for service registration and discovery that uses an RDF triple
store to express semantic service descriptions and other task/user-specific metadata,
using a mechanism for attaching structured and unstructured metadata. The result
is an extremely flexible service registry that can be the basis of a sophisticated
