Hello, we released D2RQ V0.4 today. The new version contains a wrapper which allows you to use D2RQ together with the Sesame Semantic Web framework. What is D2RQ? As Semantic Web technologies are getting mature, there is a growing need for RDF applications to access the content of huge, live, non-RDF databases without having to replicate the whole database into RDF. D2RQ is a declarative language to describe mappings between relational database schemata and OWL/RDFS ontologies. The mapping are used to access the content of non-RDF relational databases as virtual RDF graphs from the Jena and Sesame Semantic Web development toolkits. Where can I find more information about D2RQ?
