No problem Aseem! Now, a very straightforward serialization would be http://graphml.graphdrawing.org/primer/graphml-primer.html. Would that be viable? It is XML, so might not mix well.
A Gremlin script like writer = new GraphMLWriter(g) out = new java.io.ByteArrayOutputStream() writer.outputGraph(out) result = out.toString() Should do the job in the REST API. However, I think a more native way would be good to look at, too. Otherwise, there is a format that Tinkerpop is introducing that is more JSON-friendly, https://github.com/tinkerpop/blueprints/wiki/JSON-Reader-and-Writer-Librarythat you easily could emit in the same way once it has stabilized and released.
