GraphDB Free 8.0
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 an easy use and compatibility with the industry standards, GraphDB implements the RDF4J framework interfaces, the W3C SPARQL Protocol specification and supports all RDF serialisation formats. The database is the preferred choice of both small independent developers and big enterprise organisations, because of its community and commercial support, 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 10’s 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 10’s of billions of RDF statements on a single server and an unlimited number of concurrent queries. GraphDB SE is also available on-demand in the AWS Cloud, on a pay-per-use basis - see GraphDB Cloud
- GraphDB Enterprise Edition (EE) - a high-availability cluster with worker and master database implementation for resilience and high performance parallel query-answering.
