Read

(import
  [org.apache.tinkerpop.gremlin.structure.io IoCore]
  [org.apache.tinerkpop.gremlin.tinkergraph.structure TinkerGraph])

(-> (.io (TinkerGraph/open) (IoCore/graphml))
    (.readGraph "path/to/example.graphml"))

Write

(-> (.io graph (IoCore/graphml))
    (.writeGraph "output/path/to/example.graphml"))

that's not quite what i meant with this issue because if I'm reading it right, your sample code there still calls the old io() method on the Graph interface. if you notice in the link above that g.io() refers to the new io()-step that is part of the Gremlin language.

I should qualify my previous comment. You are correct: my example uses the .io method and is still very java-interop-esque. Here for anyone unless/until ogre gains io support with a more elegant, cleaner, newer approach using gremlin directly.
