Thanks for the article! I'd like to see keypaths explained a little better. For example, if CDCPerson had an NSArray *siblings (with a few CDCPerson), how could we obtain the list the siblings?

I'd think we would call it via [person valueForKeyPath: @"siblings.firstName"], but I'm not sure if I'd need extra accessors, especially if we start dealing with a fairly nested dictionary. How would that work?

Thanks again!
