Ontotext GraphDB (previously known as BigOWLIM) is a graph database[2][3] and knowledge discovery[4][5][6] tool compliant with RDF[7] and SPARQL[8] and available as a high-availability cluster. Ontotext GraphDB is used in various European research projects.[9]
As of April 2021, Graph DB is ranked as the 4th most -popular[10] RDF store[11][12] and 6th most-popular Graph DBMS system.[13] Some categorize it as a NoSQL database.[14] In 2014 Ontotext acquired the trademark "GraphDB" from Sones.
As for a typical graph DB, ontologies are an important input for the databases.[15] The underlying idea is a semantic repository.[16]
