Blazegraph is a triplestore and graph database,[1][2][3][4] which is used in the Wikidata SPARQL endpoint.
Early history
Until version 1.5, which was released 12 February 2015, Blazegraph was known as Bigdata®.[5][6]
Prominent implementations
- The Wikimedia Foundation uses Blazegraph for the Wikidata Query Service, which is a SPARQL endpoint.[7]
- The Datatourisme project uses Blazegraph as the database platform; however, GraphQL is used as the query language instead of SPARQL.[8]
Notable features
- RDF* — an alternative approach to RDF reification,[9] which gives RDF graphs capabilities of LPG graphs;[10]
- as the consequence of the previous, ability of querying graphs both in SPARQL and Gremlin;[11][12]
- as an alternative to Gremlin querying, GAS abstraction over RDF graphs support in SPARQL;[13]
- The
SERVICE
syntax of federated queries for functionality extending;[14] - Managed behavior of the query plan generator;[15]
- Reusable named subqueries.[16]
Acqui-hiring by AWS
It is alleged[17] that Amazon Neptune is based on Blazegraph.
