Abstract
One fundamental issue for semantic web application is how to define the mapping between relational model and RDF model, so that the legacy data in relational databases can be integrated into semantic web. In this paper, we propose an view-based approach to mediate relational schema using RDF-based ontology. We formally define the Ontology View, and precisely define the semantics of answering queries using ontology view. With our approach, we highlight the important role played by RDF Blank Node in defining semantic mappings and representing the incomplete part of relational schema.
