Mapping of Owl Ontology Concepts to Rdb Schemas

Modern technologies of Semantic Web, the growing complexity of information systems, the needs of knowledge bases and smart Web agents require conceptual models to gain an improved form of semantic knowledge models – i.e. ontology. Currently, the main technique of storing ontology is based on files containing descriptions of ontology in RDF/RDFS or OWL. On the other hand, the relational database technology ensures the best facilities for storing, searching, updating and manipulating information of the problem domain. The purpose of this paper is to propose the principles of mapping OWL concepts to relational database schemas, along with algorithms for transformation of OWL ontology descriptions to the relational database.
