What kind of objects? Do the object represent other entities? in that case those should be modelled as Nodes and the connection between you object and those objects as Relationships. > Thanks and sorry for the trouble... > Not at all. It would be nice though if you could elaborate on your questions with as much information as you can and perhaps code/pseudo code. It keeps other people, like me, from guessing your intents and will consequently generate better answers for you. ----- Mensaje original ----- > De: "Mattias Persson" <[email protected]> > Para: "Neo4j user discussions" <[email protected]> > Enviados: Martes, 15 de Febrero 2011 15:51:54 (GMT-0500) Auto-Detected > Asunto: Re: [Neo4j] about relationship > > Does this help: > > http://wiki.neo4j.org/content/Index_Framework#Relationship_indexes > > ? > > 2011/2/15 Jose Angel Inda Herrera <[email protected]> > > > hello Mattias > > the RelationshipIndex class which would.
