The issue was, at the time, choosing a URI style for DBpedia that would 
work with all browsers, including IE 6. Hash URIs would have been 
problematic since the # crossed the wire. DBpedia modulo IE wasn't an 
option. The goal was to deliver a Linked Data showcase that worked with 
all browsers starting with IE 6.

I believe the your quests was about a case for 303's. Which is basically 
another way of seeking a case for slash terminated URIs re. Linked Data 
deployment.
