Hi Joel,
Posts on the gremlin user group apply to JanusGraph as well. Last thing I read about gremlin-sparql

Janus as a triple store
Hi.
Is it possible to use Janus as a triple store? Is there any tool/framework that allows performing RDF-like reasoning or SPARQL queries over a Janus graph?
Best regards.

Unique composite index with label constraint - issue?
So, evaluating JanusGraph for a project, I ran into this: unique index on a Vertex property with a specific VertexLabel constraint doesn't seem to be respected across transactions? Or I'm just doing

Loading Janus DB from a distributed program
I'm trying to write a Janus DB loader for my distributed application.
I have "sub-graphs" which I can successfully load independently, per machine in my cluster. I do this by using graph.addVertex

Re: JanusGraph build and OS compatibility.
Hi Manoy,
I do not have a Titan or JanuGraph build at hand over here, but I remember there was a zip archive in the titan-dist/titan-dist-hadoop2/target folder.

JanusGraph versus Google Cayley
Dear Community,
Apologies if this is evident or has been thoroughly detailed elsewhere.
- What are the main differences (with respect to target audiences, technical details and graph functionalities)

Re: Installation of JanusGraph
We were able to build it on Mac / Linux using the instructions mentioned, however the build fails on Windows (because of a few Linux commands used therein).

Re: JanusGraph release roadmap
Ted - Thanks for the response and the link. It would be best if the team starts posting snapshot zips that can be used.
