RDFox is a main-memory, highly scalable, centralised RDF store which leverages the properties of modern computer architecture and C++ to deliver high performance parallel datalog reasoning and SPARQL query answering. RDFox’s reasoning functionality is well developed and includes aggregation and negation all supported via incremental reasoning which can help accelerate the response time of complex queries. It is available on Mac, Windows, and Linux and has been successfully deployed into client solutions by derivo.

RDFox is developed by Oxford Semantic Technologies, a spin out from the University of Oxford backed by leading investors including Samsung Ventures and Oxford Sciences Innovation.
