Dave,
Hasn't there been some work on creating abstract representations of
schemas? For comparison purposes?
I will look for it over the weekend but for some reason I think there is
something other than Trang (which is really cool) that might fit the bill.
But thanks for the reminder about Trang. Fairly sure what work there is
would have cited it as other work or as a reference.
Hope you are looking forward to a great weekend!
Patrick
