GraphDB Enterprise is a high-performance semantic repository created by Ontotext. It is implemented in Java and packaged as a Storage and Inference Layer (SAIL) for the RDF4J framework. Loading, reasoning and query evaluation proceed fast even against huge ontologies and knowledge bases.
GraphDB allows you to link text and data in big knowledge graphs. It’s easy to experiment with its functions such as inserting and transforming any type of data into RDF format, the SPARQL editor, FTS connectors, visualization, geospatial and ranking. GraphDB offers Data Reconciliation, Ontology visualization and high-performance cluster proven to scale in a production environment. GraphDB offers also MongoDB integration for large-scale metadata management, semantic similarity search, based on graph embeddings, fast and flexible full-text search (FTS) connectors, such as SOLR and Elasticsearch.
|Typical application scenarios|
Metadata enrichment and management, linked open data publishing, semantic inferencing at scale, enterprise semantic search applications and data warehousing.
BBC, Press Association, Financial Times, DK, Euromoney, The British Museum, Getty Trust, UK Parliament, Raytheon, Korea Telecom, Springer Nature, Elsevier, Oxford University Press, Wiley, S&P Global Platts, and many others
GraphDB is the most utilized semantic triplestore for mission-critical enterprise deployments. Heavy-duty, high-availability, robust and scalable it fits perfectly in any enterprise infrastructure when stability and predictability are key.
|Licensing and pricing models|
GraphDB-Free is free to use. SE and Enterprise are licensed per CPU-Core used. Perpetual and annual subscription models are available.
