Abstract:
Query engines for managing RDF repositories based on relational technology represent an alternative to query engines based on triple-stores. The paper presents adaptation of object-relational technology for managing RDF data. The architecture of query engine for RDF databases is proposed: i) mapping of RDF graph model to object-relational representation is described, and ii) internal structures and methods used for the implementation of query engine are discussed. While following the architecture of object-relational systems we adapt it for the specific operations defined on RDF data.
