You set persistant data on an object by just setting it.
object.foobar = 6
That's all you need to do. If you create object classes that should be used:
object.foobar = MyObject()
then it need to inherit from Persistence.Persistent.
If you are using mutable types like lists and dictionaries, you need to
use Persistent version of them, called PersistentList and
PersistentMapping. In your case, with large amounts of dictionaries, you
also might want to look into using BTrees to speed things up.
