We are developing a multi-database architecture to provide integrated access to heterogeneous, distributed databases. The work described here is motivated by the desire to have RDF/RDFS collections as component data resources in this system, along with relational and other databases. To achieve this, the RDF/RDFS collection, like all other component resources in the system, is mapped to the functional data model, and a query translator is implemented that can translate queries originally expressed in Daplex (the query language associated with the functional data model) into SPARQL. SPARQL is the prominent query language for RDF and it is used here to bridge between the functional data model and the Semantic Web.
