I think it really leads you down the wrong path to talk about first minting the URI and then putting something out  there that explains what you meant by it. I know thats what people WANT to think, but it leads you to imagine that a URI could have two senses, one the "natural", undocumented sense, and another the sense which appears when you put up the description (and disappears when the server goes down for the last time).

You can avoid this fallacy merely by being more careful about the order. Your dbpedia server arranges its state so that subsequent later requests for a URI will (DNS and Apache willing) result in some results. But the URI choice is constrained almost completely by the server configuration, DNS, available protocols, etc.

You can change the case of the host, add or omit the port, perhaps hex encode some characters or even do Unicode normalization and get the same behavior.

If you are depending on the web behavior to establish meaning, then all of those spellings should mean the same thing.

If you are not, if the web behavior of the URI is just advisory and you could use http://example.com and HTTP://eXAMplE.com:80<http://eXAMplE.com:80>/ to meam different things, then why bother setting up a server at all?

When publishing Linked Data via a Linked Data oriented server.

DBpedia is a live example. The server is *minting* URIs to serve a very
specific purpose :-)
