| Abstract [eng] |
The goal of the paper is to define requirements to OWL 2 ontologies, under which their semantics may be preserved in a relational database, and to demonstrate that the hybrid approach for transforming OWL 2 ontologies into relational databases possesses such capability. The hybrid approach maps part of ontology concepts to relational database concepts on the base of their common semantics; ontology constructs having no direct equivalents in databases are stored in metatables. The paper defines requirements for ontologies under transformation as ontology normalization and integrity rules, and presents a set of SQL queries for extracting rich data, covering semantics of source ontology, from the resulting database. The capability of the hybrid approach to preserve semantics of OWL 2 ontologies in relational databases is demonstrated with a representative example of a Vehicle ontology. |
