The FUSION approach has studied the methodologies and the lessons learned by
research efforts focusing on the semantic enrichment of formal service registries
and tries a different and innovative orientation. As the FUSION approach seeks
to benefit more from the emerging Semantic Web technologies and standards, it
moves towards the implementation of a ???pure??? FUSION semantic registry, based
on a full functional RDF semantic repository (see Figure 6). FUSION approach
develops a ???thin-UDDI??? API, internally to the semantic registry, to realize the basic
set of functions of the traditional registries. In order for the proposed approach
to be fully compliant with the dominant standards of the e-business domain (i.e.,
UDDI), FUSION transforms the XSD Schema of the latest UDDI specification in a
RDF-Schema stored in the developed RDF repository, so as to preserve the widely
known informational and relational infrastructure of the UDDI registry and to take
advantage of its well-defined internal structure. This implementation benefits from
the new possibilities provided by the RDQL query language when combined with
the reasoning and inference engine of the RDF repository facilitates.
