[Zope] How to display the owner of an object?

Hi all, I know that this has been a topic on this list before, but what I found in the archives didn't really bring me any further. All I want to do ist to display the owner of an object. Is there a way to do this easily? Basically what I want to do is something like this: <dtml-in "Catalog(sort_on='sort_date', sort_order='reverse')"> <dtml-var id_or_title> <dtml-var owner> # Is there something like this?? </dtm-in> Is there a predefined variable for the owner of the object?
