Abstract :
We study the problem of answering queries through a target RDF ontology, given a set of view-based mappings between one or more source relational schemas and this target ontology. We design a novel query rewriting algorithm that can efficiently rewrites a RDF query into relational queries using a set of RDF views. With our approach, we highlight the important role played by RDF blank node in representing incomplete semantics of relational data when integrating them using RDF
