OpenDFKI RDFBroker

Many approaches for RDF stores exist, most of them using very straight-forward techniques to store triples in or mapping RDF Schema classes to database tables. RDFBroker is an RDF store that uses a natural mapping of RDF resources to database tables that does not rely on RDF Schema, but constructs a schema based on the occurring signatures, where a signature is the set of properties used on a resource. This technique can therefore be used for arbitrary RDF data (i.e., RDF Schema or any other schema/ontology language on top of RDF is not required). Our approach can be used for both in-memory and normal (on-disk) relational database-based RDF store implementations, and also distributed RDF stores (with distributed query handling) benefit from it.
