摘要：The goal of the paper is to define reversible, information preserving transformation from OWL 2ontologies into relational databases using our proposed hybrid approach, when a part of ontology constructs is directlyrepresented by relational database structures and another part having no direct correspondences in a relational databaseis stored in metadata tables. The desirable transformation is defined in QVT Relations language following additionalrequirements under which such transformation is reversible and does not lose semantic information when performingfrom ontology to database and backward.
