What you describe here is a ternary edge, something I try to cover in the Enhanced API.
Your film example can be modeled as follows: There is an Edge "STARS" with the EdgeRoles: "Actor", "Film", "Role". We can now state: STARS -- Actor -- Brad Pitt -- Film -- Fight club -- Role -- Tyler Durden STARS -- Actor -- Edward Norton -- Film -- Fight club -- Role -- Fight club narrator, Tyler Durden or we can state STARS -- Actor -- Brad Pitt, Edward Norton -- Film -- Fight club -- Role -- Tyler Durden STARS -- Actor -- Edward Norton -- Film -- Fight club -- Role -- Fight club narrator or we can state STARS -- Actor -- Brad Pitt -- Film -- Fight club -- Role -- Tyler Durden STARS -- Actor -- Edward Norton -- Film -- Fight club -- Role -- Fight club narrator STARS -- Actor -- Edward Norton -- Film -- Fight club -- Role -- Tyler Durden Niels > Date: Sat, 6 Aug 2011 15:51:51 +0800 > From: asianf...@gmail.com > To: user@lists.neo4j.org > Subject: Re: [Neo4j] Keeping context information in the Graph > > This may be the same solution suggested by Dmitriy, but I had to visualise > it to understand the problem.
