writing it back to the file in the traditional sense is a bit of a mystery

If I understand correctly what you want to do, then this applies:

"Your application code—and in particular the application logic associated with managed objects—should not make any assumptions about the persistent store in which data may reside."

You should not directly modify any native Core Data stores.

If you want to use your own file format, then see <http:// developer.apple.com/documentation/Cocoa/Conceptual/CoreData/Articles/ cdImporting.html> -- you'll also have to ensure you properly manage writing the file on save.
