Aha!

You're saying that catalog_object and uncatalog_object are
methods of the catalog, so when the catalog contains the
objects directly, it's all that's neccessary, correct?

index_object, unindex_object, and reindex_object (the
CatalogAware methods) are all methods on the object to be
indexed, not methods of the catalog, as I understand. When
called, they find the nearest (acquisition-wise) ZCatalog
(named Catalog by default), and cause catalog_object and
uncatalog_object to be called on it (I'm not sure what
method reindex_object causes to be called).

So, postings would only need to be CatalogAware if you
wanted them to be able to 'live' anywhere within the Zope
heirarchy, instead of being contained directly within the
Squishdot object (which inherits from ZCatalog).


Do I have this correct?
