You can either use the PersistentMapping object that comes with Zope
"from ZODB.PersistentMapping import PersistentMapping" or
AndrewWilcox's http://www.zope.org/Members/AndrewWilcox/PersistentListDict.
PersistentMapping is limited to string keys only, which is sufficient most of the
time.
Just create a PersistentMapping in your Zope class and use it as if it was
a regular python dictionary. PersistentMapping takes care of setting
the necessary attributes for it to be persistent.
Alternative you can use a TinyTable directly in Zope for storing a table.
