DataMaster is a Protege plug-in for importing schema structure and data from relational databases into Protege. DataMaster supports both OWL and frame-based ontologies and can be used with any relational database with JDBC/ODBC drivers.

Part of the rationale for developing DataMaster was that existing Protege plug-ins such as DataGenie do not support OWL ontologies or schema-only imports.

This plug-in is NOT a database back-end. The typical use-case for this plug-in is importing legacy data into Protege before doing additional knowledge acquisition or knowledge modeling. This plug-in currently does not include any capability for moving data in the opposite direction, i.e., from Protege classes and instances into a relational database. Another use-case for this plug-in might be to import a database schema as classes or instances in the ontology which may be later used to dynamically query the content of the database using SQWRL queries. DataMaster could be also used as a database viewer. For efficiency, a database might be stored as a set of custom-designed database tables, but then DataMaster could be used to view portions of the schema from within Protege user interface.


DataMaster is bundled with the "full" installation of Protege (versions 3.3.1 and higher).

For instructions related to JDBC driver installation please read the Documentation section below.


A good overview of the functionality of the DataMaster plug-in is available in the abstract for the presentation about DataMaster at the 10th International Protege Conference.

More documentation to come very-very soon.

DataMaster can be also used to import database schema and data from MS Excel spreadsheets, by using an enhanced version of the xlSQL JDBC driver. For instructions please read the special wiki page created for the xlSQL-Y8 driver.

Level of Support

Please post questions about the DataMaster plug-in to the protege-discussion or protege-discussion mailing lists.

The source code for DataMaster is available from the Protege Subversion repository.


This work was supported by the Centers for Disease Control and Prevention under grant number SPO-34603. We would also like to acknowledge the DataGenie plug-in, parts of which were adopted by DataMaster.
