This doesn't work with isKindOfEntity, used like that :
NSEntityDescription* rootDescription = [[NSEntityDescription
entityForName:@"root" inManagedObjectContext:[self
managedObjectContext]] retain];
...
[rootDescription isKindOfEntity:[modEntry entity]]
It's always return NO...
Is "root" the name of the *entity* or of the *class* used to represent
the entity?
Whichever, it's helpful if you adhere to standard naming conventions
by capitalising the names of both.
If the entity name is "root", then do the "song" and "artist" entities
inherit from that entity?
