Cayenne and Core Data

Hello.

Cayenne[1] is an Java Object Relational Mapping framework. It has support for Remote Object Persistence (ROP)[2].

I have done some work to create a Cocoa client for Cayenne ROP. This would however not be complete without some sort of Core Data support.

What it need Core Data support for: * Adding to a to-many relationship is currently working, but not to a non-related or master entity. The NSArrayController should be able to automatically register new objects with the object context. * Supporting the "Delete Objects On Remove"-feature set to true/ false in IB. * +++?

I can see several possible ways to do this, but do not know if any of them are possible. * Use Core Data unmodified and just hook on the the object store part of it. * Subclass or implement NSManagedObjectContext so that the Cayenne Client is used. * Not use Core Data at all, but using some other mechanism to do the same things.

I do not know how to get started with the Core Data support for the Cayenne client. Any pointers to related projects and/or documentation are wanted.
