GraphDB (former OWLIM) is the most scalable semantic repository. It includes triple store, inference engine and SPARQL query engine. It is packaged as a Storage and Inference Layer (SAIL) for the Sesame RDF database. GraphDB uses the TRREE engine to perform RDFS, OWL DLP, OWL Horst reasoning and OWL 2 RL. The most expressive language supported is OWL 2 RL, Containing RDFS. GraphDB offers configurable reasoning support and performance. It comes in five editions: Standard, Enterprise, Database-as-a-Service on S4, Cloud on AWS and Free.
