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

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.
