No, not really. The Book class is purely a data class - the M(odel) of MVC ;).
In fact, you shouldn't be importing Cocoa.h in it.

The only classes that will be using Cocoa will be MyDocument - which Xcode creates automagically when you start a new cocoa document-based application - and possibly your controller if you subclassed NSArrayController.
