Working with RDFox

RDFox Secondary Logo


Rules are modelled with the industry standard Datalog language, and can operate incrementally.

RDF triples illustrated


RDFox ingests data in the open standard RDF-triple format which can easily be converted to and from SQL or CSV sources.

RDFox was designed around high-speeds at the University of Oxford


Improve enterprise performance with the fastest loading linked data triplestore and by materalising data ahead of query time.​
