Dependent keys won't help me here. My problem is that a key in the

I've read the Key Value Coding/Observing documentation, and a fair
bit of the Bindings documentation. As yet, I have found no simple
way to register dependent key paths, which is what I need to be able
to do.
(Provided that the path doesn't include to-many relationships, which
appears to be true in your case.)
I'm afraid my knowledge of Core Data is rather limited. It seems
like it would work wonders for managing my data model, but I have a
few reservations. Namely, none of the built-in persistent stores
meet my needs.
In what way are your needs not met?
How difficult is it to either query the entire object graph (so I
can write out a file manually)
It's not clear what you mean.
You save changes by sending the managed objet context a save: message,
and the file is saved.
