RDF+OWL to Relational Mapping + OBDA Access

  1. Mapping of RDF data according to an OWL ontology to the relational model and store it in a relational database.
  2. Populate the database from RDF tuples.
  3. Queries can then be stated either in SQL, or in SPARQL which is automatically translated to SQL.

The prototype implementation RDF2SQL can be found here.
Note: to play with the prototype, first run the "init" button to create a new database - parts of it are in-memory of the Web Service instantiation, which is destroyed when it is not used.
