From Relational Data to RDFS Models

A vast amount of information sources is stored as relationallike data and inaccessible to RDFS-based systems. In this paper we describe an approach to integration such information sources with RDFSaware systems. The proposed solution is purely RDFS-based. We use RDF/S as a mechanism to specify and perform linking of relational data and a predefined domain ontology. The approach is transformation-free, therefore, it completely preserves the original structure of relational data and eliminates the need for a run-time transformation component. This ensures that all the data is accessible and usable in consistence with the original data model.
