Awesome work Marko! Yes, GraphML export/import is a great component idea that we certainly will take up in the near feature in order to get data in and out in a standard way.
Also, Gremlin is becoming more stable and thus filling an empty space between SPARQL, XPATH and full traverser power in graphs for declarative querying. Do get back to the list on your progress there!
