You need a ZODB connection in order to be able to change objects
in the ZODB.
You get one (in your new thread!) by
from Zope import app
root= app() # the ZODB root object but without 'RequestContainer'
You can now build a new REQUEST object and use "BaseRequest.traverse"
to reach the object you want (identified by an URL).
Before you change anything, you need to begin a transaction
and finally either commit or abort it.
