Core Data Conundrum

Hi. I'm trying to set up a model for a Node and a Segment. A Segment exists between Nodes. Each Segment has a node1 and node2 attribute, and each Node can have multiple Segments. I don't seem to be able to model this relationship; I can have either node1 with an inverse of segments, or node 2, but not both.

It's important for me to distinguish which end of a segment a particular Node is associated with (imagine drawing a directed arrow). I feel like this should be straightforward, but I'm stuck.

Any suggestions?

TIA,
Rick
