* access them via an instance
* search the mailing list archives: you will find an
(unintuitive) solution (from me) to access the attribute
inside the class

Such modifications are lost when Zope restarts.
Like many other so called OODBs, ZODB is *NOT* a true object oriented
database but just an object state database. It manages only the state,
it does not store the classes. Any changes to classes are lost
after a restart (This does not apply to ZClasses, which are
objects and behave like classes).
