About GraphDB

GraphDB is a family of highly efficient, robust and scalable RDF databases. It streamlines the load and use of linked data cloud datasets, as well as your own resources. For easy use and compatibility with the industry standards, GraphDB implements the RDF4J framework interfaces, the W3C SPARQL Protocol specification, and supports all RDF serialization formats. The database is the preferred choice of both small independent developers and big enterprise organizations because of its community and commercial support, as well as excellent enterprise features such as cluster support and integration with external high-performance search applications - Lucene, Solr and Elasticsearch.

GraphDB is one of the few triple stores that can perform semantic inferencing at scale, allowing users to derive new semantic facts from existing facts. It handles massive loads, queries, and inferencing in real time.

Ontotext offers three editions of GraphDB: Free, Standard and Enterprise.

  • GraphDB Free - commercial, file-based, sameAs & query optimisations, scales to tens of billions of RDF statements on a single server with a limit of two concurrent queries;
  • GraphDB Standard Edition (SE) - commercial, file-based, sameAs & query optimisations, scales to tens of billions of RDF statements on a single server and an unlimited number of concurrent queries;
  • GraphDB Enterprise Edition (EE) - high-availability cluster with worker and master database implementation for resilience and high-performance parallel query answering.
