The UID is an application-specific token for the indexed object.  It is
what gets displayed on the 'Catalog' tab.  Often, it will be the
physical path, or a subset of it (e.g., trimmed to be relative to the
current "site").  Have a look at the CatalogAware class for how the uid
is generated.  The Zope2 version uses a a goofy version of a virtual
hosting-aware URL:

The CMF version lets the catalog figure it out:

http://svn.zope.org/Products.CMFCore/branches/2.1/Products/CMFCore/CMFCatalogAware.py?rev=82471&view=auto
http://svn.zope.org/Products.CMFCore/branches/2.1/Products/CMFCore/CatalogTool.py?rev=81780&view=auto
