A Database Backend for OWL

Abstract. Most Semantic Web applications are build on top of technology based on the Semantic Web layer cake and the W3C ontology languages RDF(S) and OWL. However RDF(S) embodies a graph abstraction model and thus is represented by triple-based artifacts. Using language for Semantic Web knowledge-bases, this abstraction no longer holds. OWL is build up on an axiomatic model representation. Consequential storage systems focusing on the triple-based representation of ontologies seem to be no longer adequate as persistence layer for OWL ontologies. Our proposed system allows for a native mapping of OWL constructs to a database-schema without an unnecessary complex transformation in triples. Our Evaluation shows that our system performs comparable to current OWL storage systems. 1 Motivation The requirements for Semantic Web applications often include the need to store large amounts of data, in particular when interconnected data is considered3 . In such situations the accessible data is ...
