Thanks for the explanation but I'm still struggling a bit. I don't  
understand event.zcml - do I need to confifure a subscriber for my  
object?

 >>> a = aContentObject.aFactory()
 >>> from Products.CMFCore.interfaces import IContentish
 >>> IContentish.providedBy(a)
True
 >>> a.getId()
''

so the object is not aware of a UID if it has one. Is this wrong way  
to create such an object or should I be asking Zope to give me the  
UID? If I do depend on Zope to generate a UID for me then how I do add  
them to a folder? I can't use invoke_folder because that expects both  
the type name and the id.

Guess it's back to perusing the books.
