Another possible option is CDBStore framework. I haven't personally used it, but it claims to fill the gap between archiving/property lists and Core Data.

I have an application whose data model is an NSMutableArray with elements that could be pointers other NSMutableArrays, much like what you would navigate with a NSIndexPath. I am using NSKeyedArchiver to archive the data model to a file. Right now I archive the entire top level array object (and
therefore all its parts) to the file using archiveRootObject:toFile.
Is it possible to archive only the portion of the data model that changed

 There is no direct "Cocoa Way" to do this, AFAIK. Consider Core Data
(using the SQLite store type).
