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.

Trello Board

• Written in Go
• 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:
  • JavaScript, with a Gremlin-inspired* graph object.
  • (simplified) MQL, for Freebase fans
• Plays well with multiple backend stores:
  • LevelDB
  • Bolt
  • MongoDB for distributed stores
  • In-memory, ephemeral
• Modular design; easy to extend with new languages and backends
• Good test coverage
• Speed, where possible.

Rough performance testing shows that, on 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.

* Note that while it's not exactly Gremlin, it certainly takes inspiration from that API. For this flavor, see the documentation.
