No, persistent is OK. I just thought that it wasn't that's all. > > > > > The nodes that I'm relating to each other in the Timeline are not > > themselves > > directly related.

I don't know the capabilities of the Timeline, but I guess since the docs don't mention nodes must themselves be related I assume it'll probably work. > > > > > Thanks, > > Tim > > > > > > > > > > _______________________________________________ > > Neo4j mailing list > > [email protected] > > https://lists.neo4j.org/mailman/listinfo/user > > > > > > -- > Mattias Persson, [[email protected]] > Hacker, Neo Technology > www.neotechnology.com > _______________________________________________ > Neo4j mailing list > [email protected] > https://lists.neo4j.org/mailman/listinfo/user > _______________________________________________ Neo4j mailing list [email protected] https://lists.neo4j.org/mailman/listinfo/user
