Greetings Zopistas!

I'm currently working on a site which requires that I store City, State =
and Country entries in a hierarchy such that multiple cities can roll up =
under a state and multiple states can roll up under a country.  To =
accomplish this, I have a created a small python product called =
LocationManager which stores data as follows:

USA
=A0=A0=A0=A0 Massachusetts
=A0=A0=A0=A0=A0=A0=A0=A0=A0 Boston
=A0=A0=A0=A0=A0=A0=A0=A0=A0 Lexington
=A0=A0=A0=A0=A0=A0=A0=A0=A0 Concord
=A0=A0=A0=A0 Illinois
=A0=A0=A0=A0=A0=A0=A0=A0=A0 Chicago
=A0=A0=A0=A0=A0=A0=A0=A0=A0 Evanston
=A0=A0=A0=A0 California
=A0=A0=A0=A0=A0=A0=A0=A0=A0 Los Angeles
=A0=A0=A0=A0=A0=A0=A0=A0=A0 San Diego
Canada
=A0=A0=A0=A0 Quebec
=A0=A0=A0=A0=A0=A0=A0=A0=A0 Montreal
etc


What i would like to do is use a Catalog to flatten that data out and =
enable me to retrieve all of the cities in one fell swoop.  I've read =
over the ZCatalog tutorial and have searched zope.org, and I think I see =
how to catalog properties of products.  However, I haven't really found =
anything that describes:
a)  How to build a python product that is catalog aware?
b)  How do i retrieve the data from the catalog without a search =
interface?

URLs to any resources, or any answers to my questions would be MOST =
appreciated.

Thanks so much,
Keith R. Alperin
