There's something wrong here. #4 is the inverse of #3, so it should say "and its inverse: parentFile", shouldn't it. Otherwise it would conflict with #1 and give you a warning. So I'm guessing this is just a typo in your post? One way you clarify all of this would be to rename all your relationships in a clearer way. (And, possibly, to rename the Child entity, since "Child" sort of conflicts with the loose parent/"child" relationship terminology that we could use for both hierarchies.) So, you could say that Child's 3 relationships are childSubnodesOfChild, parentChildOfChild and parentFileOfChild. The File's 3 relationships are fileSubnodesOfFile, childSubnodesOfFile and parentFileOfFile. Does that make it any clearer? _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
