- Abstract
We describe a relational database semantic re-engineering technology and the tools that are available for its implementation. The semantic re-engineering technological process starts with creatinga conceptual data ontology together with its annotations for database schema and user interface mappings. The database schema mappings are implemented in RDB2OWL and D2RQ server thus creating a SPARQL-endpoint for "semantic" access to the relational database contents. The SPARQL endpoint can be explored by the user interface automatically generated by OBIS system, or ViziQuer tool may be used for custom SPARQL query generation in a graphical way. We report on successful application of the approach on the Latvian medical data with the ontology containing 172 OWL classes, 138 object properties, 814 data properties, and about 40 million data level RDF triples.
