PHP implementation of the D2RQ Mapping Language

The Semantic Web aims at giving data more structure and computer understandable meaning. For that RDF enables to add metadata to the unmanageable mass of data in the World Wide Web. Hence, the transformation of data located in relational databases to RDF plays an essential role. To provide such functionality our implementation R2D2 maps an RDF query to a legacy relational database without having to replicate the data.
