RDFox is a highly scalable in-memory RDF triple store that supports shared memory parallel OWL 2 RL reasoning. It is cross-platform software written in C++ that comes with a Java wrapper allowing for easy integration with any Java-based solution, including the OWL API.

RDFox is very fast. It can materialise LUBM-50k (6.7B triples) in 1,100s using 32 cores, and this reduces to only 387s when using 128 cores. It typically requires about 60-110 bytes per triple; e.g., it uses 600GB to store the 7B triples from Wikidata.

RDFox also has many advanced features, including native support for owl:sameAs, incremental update, and extensive SPARQL support.
