Reversible lossless transformation from OWL 2 ontologies into relational databases

Abstract

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