Re: [Neo4j] Traversal Framework question

Hi, Traversal.description() .depthFirst() .relationships(RelationshipTypes.CREATED, Direction.BOTH) .traverse(developer).nodes() To be clear, a co-creator is someone is who has created the same things as you and who is not you. Thus, you need to go outgoing CREATED, then incoming CREATED,

Re: [Neo4j] Traversal Framework question

Hi, Just to be picky: The easiest way to do that in this case is by adding: .uniqueness(Uniqueness.NODE_PATH) A co-creator's co-creator can be you. Thus, marko's co-creator's co-creator is marko (amongst other people). In this case, unique on a path would not fail, no? Can you do something

Re: [Neo4j] Traversal Framework question

Marko, I don't understand what you are trying to say. Is the question about finding, given a person node, the co-creators for that person on any project? Or is it about reasoning in the abstract co-creator graph. I was under the impression that finding co-creators was the only thing we were

Re: [Neo4j] Traversal Framework question

Hi there, I think something like returning all but the start node would do the trick in this special, see http://api.neo4j.org/1.2/org/neo4j/graphdb/ReturnableEvaluator.html#ALL_BUT_START_NODE or similar. More generally, if you want to see the history of things, you can examine the provided PATH

Re: [Neo4j] traversal framework question

Hi Joshi, the problem may be that your traversal description will traverse from actor to director (in both directions) and also from director to actors (also in both directions). Your manual traverser traverses actors to directors in both directions and then only incoming relationships from
