Morph-RDB

Morph-RDB (formerly called ODEMapster) is an RDB2RDF engine developed by the Ontology Engineering Group, that follows the R2RML specification. It supports two operational modes:

• Data upgrade: generating RDF instances from data in a relational database.
• Query translation: from SPARQL to SQL.

For this purpose, it employs various optimisation techniques in order to generate efficient SQL queries, such as self-join elimination and subquery elimination.

Morph-RDB has been tested with real queries from various Spanish/EU projects and has proven to work faster than other state-of-the-art tools available. At the moment, Morph-RDB works with MySQL, Oracle, PostgreSQL, H2, CSV files and MonetDB.
