That code looks pretty good to me. Did you try updating the Catalog?
Also, what happens if just append catent. Do you get something other
than None then? I would assume so, but it might help to see exactly what
the meta data is to identify the objects it "should" return.

I agree that getobject should be a method of the result item, although
implementing it might be a bit tricky to do. I looked into that a while
back. Perhaps I should take another look at that...
