RDFox is a highly scalable in-memory RDF triple store that supports shared memory parallel datalog reasoning. It is a cross-platform software written in C++ that comes with a Java wrapper allowing for an easy integration with any Java-based solution. It is available on Mac, Windows, and Linux.
After the initial development at University of Oxford, the system is now ready for production and is available commercially from Oxford Semantic Technologies, a spin-out of the University backed by Samsung Ventures and Oxford Sciences Innovation. For users in academia, RDFox can be used under a noncommercial academic license. Please contact Mary Catherine DiNunzio (firstname.lastname@example.org) to obtain the license and the binaries.
