[Zope-dev] creating products

[Dirk Datzert]

Hi,

I want to write a simple product which saves some data.

Which base python-zope class is necessary to store user-structured data
in the following format:

zope-container
  non-zope structure object 1
  non-zope object-container
    non-zope structure object 2
    ...

Which base class must be the zope-container ? 
SimpleItem, PropertyManager, ObjectManager, or what.

Which base class must the non-zope structured data ?
Persistent, PropertyManager, SimpleItem

Regards,
Dirk
