I saw this question asked, but didn't see an answer - what's a "ZCatalog-aware ZClass" involve?

looking at the ZCatalog source, it looks like one way would be to make the code that adds the object instance search for a ZCatalog object, then call catalog.catalog_object(object, objecturl) - and the delete method should then call catalog.uncatalog_object(objecturl).

Exactly. In most cases 'search for a ZCatalog' would just be acquisition.

Is it just a matter of making a single class that does just this, and make the ZClasses you build inherit from it? Or is there a simpler way?

The easiest way we've found is to make a Z(Base)Class called 'Findable' which impliments the adding, deleting, and findable attributes (which you can override in (Sub)Zclasses). How can it get any simpler than that? I suppose it could cook breakfast for you. ;) -Michel
