[Zope-dev] Object ownership

I've been making some assumptions about how ownership works, and I'd appreciate it if anyone could tell me if they are right. 1) The owner of an object is the authenticated user when the script that creates it runs. 2) So User objects have an owner of superuser, not themselves. 3) I can programmatically create an object graph, and the ownership of the parts of the graph will be right. 2) is an implication of 1), but seems a bit odd. Thanks.
