I am working on an NSPersistentDocument-based app and, on the advice received here, have worked out the code to keep data version information stored in the metadata of my data file. I figured that the best place to put version checking and updating code would start with the MyDocument object, but I can't seem to convince this object to send a message to other objects from the - (BOOL)readFromURL: (NSURL *)url ofType:(NSString *)fileType error:(NSError **)outError method.

Why aren;t you using - (BOOL)configurePersistentStoreCoordinatorForURL: (NSURL *)url ofType:(NSString *)fileType error:(NSError **)error?
