[Zope] Finding owner of an object

[Tom Emerson]

Greetings,

I have a folder of files (think the FileLibrary example), where files
may be owned by different people. In a ZPT I would like to limit the
set of files that are displayed to those owned by the current user. I
can't find a way to get the owner of a given object: what am I
missing?

For example, I use

container.Submissions.objectValues('File')

to get the set of files in the Submissions folder. Is there a method I
can call on each File object to get its owner?

TIA,

    -tree
