It's fairly similar to Zope2 ids. There is no standard id in addition
the the name.

IReadContainer and IWriteConteiner will tell you about containers.
ILocation is also relevant.
Basically containers work like standard python dictionaries. The
__parent__ attribute is a link to the parent. Zope 2 used acquisition
Also you should know that if objects don't support ILocation then they
will be wrapped in a containment proxy by their container.
Check out the programmer tutorial for more information.
