Hi all, we just released the initial version of D2R MAP a database to RDF export tool. D2R MAP is implemented in Java and is based on the Jena API. It exports data from a relational database as RDF, N3, N-TRIPLES and Jena models. It is compliant with RDBMS offering JDBC or ODBC access. To describe the mapping between a database schema and a RDF schema or OWL ontology D2R uses a declarative, XML-based mapping language. The mapping language is flexible and (hopefully) easy to understand. It supports + highly normalized table structures, where instance data is spread over several tables, + references within the model to instances dynamically created in the mapping process, + the use of patterns and value substitution tables for identifier construction and data transformation in the mapping process. The D2R language specification and a usage example is found at http://www.wiwiss.fu-berlin.de/suhl/bizer/d2rmap/D2Rmap.htm The tool can be downloaded from http://sourceforge.net/projects/d2r-map/ We have tested the tool on Windows with a MS Access database and on Linux with MySQL. So any feedback about the mapping language and how the tool works with different databases and on different platforms is highly welcomed. Cheers Chris Bizer
