Note that the 303 heuristic is now just an option. You can now do a 200 
OK on a hashless URI and then use "Content-Location: " header to aid 
disambiguation i.e., the Content-Location: header is the final arbiter 
for hashless URI disambiguation. Thus, 
<http://dbpedia.org/resource/Linked_data> can now result in a 200 OK 
with <http://dbpedia.org/page/Linked_data> returned in the 
"Content-Type" response header.

I also posted this to the LOD forum encouraging adoption of this new 
heuristic as yet another option for URI disambiguation. Naturally, we 
will incorporate this into DBpedia once we are clear it won't trip up 
existing LOD consumers and we arrive at consensus with other project 
members.
