Is it possible to have more than one data model in a project?

Yes.

I.e. could i have one data model and persistant store for the application itself, and another for documents?

<http://developer.apple.com/documentation/Cocoa/Reference/ ApplicationKit/ObjC_classic/Classes/NSPersistentDocument.html#// apple_ref/doc/uid/TP30001179-CJBJBIHA>

And further, would it be possible to communicate between these two stores, etc.

<http://developer.apple.com/documentation/Cocoa/Reference/ CoreData_ObjC/Classes/NSPersistentStoreCoord.html>

"The object is designed to present a facade to the managed object contexts such that a group of persistent stores appears as an aggregate store. A managed object context can then create an object graph based on the union of all the data stores the coordinator covers."
