Titan REST endpoint

Titan can speak REST.

From Connecting via REST:

Gremlin Server provides for a single REST endpoint - a Gremlin evaluator - which allows the submission of a Gremlin script as a request.

FIXME What follows is a very rough note

If you uncommented out com.tinkerpop.gremlin.server.channel.HttpChannelizer, you'd be able to execute queries using two REST APIs:

• http://localhost:8182/graphs
• http://localhost:8182?gremlin

➜  ~  curl -i -H "Accept: application/json" http://localhost:8182/graphs -d '{"gremlin": "g.v(10240256)"}'
HTTP/1.1 200 OK
Content-Type: application/json
Content-Length: 325
Connection: keep-alive
