RDF+OWL to Relational Mapping + OBDA Access
- Mapping of RDF data according to an OWL ontology to the relational model
and store it in a relational database.
- Populate the database from RDF tuples.
- 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.
