Cayley

Cayley is an open-source graph inspired by the graph database behind Freebase and Google's Knowledge Graph.

Its goal is to be a part of the developer's toolbox where Linked Data and graph-shaped data (semantic webs, social networks, etc) in general are concerned.

Features

  • Community driven
  • Written in Go
    • can be used as a Go library
  • Easy to get running (3 or 4 commands, below)
  • RESTful API
    • or a REPL if you prefer
  • Built-in query editor and visualizer
  • Multiple query languages:
  • Plays well with multiple backend stores:
  • Modular design; easy to extend with new languages and backends
  • Good test coverage
  • Speed, where possible.

Rough performance testing shows that, on 2014 consumer hardware and an average disk, 134m quads in LevelDB is no problem and a multi-hop intersection query -- films starring X and Y -- takes ~150ms.
