Dear list
I have a product which I want to extend.
I want to add a property.
In my ZODB I all ready have ~1000 objects stored. And I would hate if I 
have to add them again.
Is there a way to update the existing objects?
Simply add the new property to your global class defintion and to the 
PropertySheet-defintion:

class YourObjectClass(SimpleItem, PropertyManager):
     """ A class to build ... """

     newProperty = ''

     _properties = ({'id': 'title', 'type': 'string', 'mode': 'w'},
                    {'id': 'newProperty', 'type': 'string', 'mode':'w'},)

Zope will update your existing objects at startup this way.
