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.
