I haven't done this myself, but it sounds like an in-memory store might work. See "Custom store types" here: http://developer.apple.com/documentation/Cocoa/Conceptual/CoreData/ Articles/cdPersistentStores.html#//apple_ref/doc/uid/TP40002875- DontLinkElementID_77

Since you are responsible for saving the objects and you want them temporary, you can just fail to do any saving. :) However, if you want to use relationships from the persistent objects, you'll run into difficulties, as cross-store relationships are not supported. You may be able to use a Fetched Property using the URIRepresentation or objectID, but again I haven't done that before either.

Hope that helps,
George
