This is probably a very simply question but I'm a rank novice.... I have created an application in XCode using CoreData and the xcdatamodel tool included in XCode. The program works fine, but I've realized that I need to tag the data file with a version number so I can add features and not run into problems when the data file is not up to date with the program.

You can use the metadata area of the store to tag the file with version information. See the metadata related methods on NSPersistentStoreCoordinator.
