Hi Peter:
While I agree with John, I disagree with your statement that:
>We know that a fundamental part of the WWW architecture is cracked - the inability to use URIs to distinguish between a name of something and an address describing >that something - so why not use a standard that addresses (excuse the pun) the issue correctly, consistently, coherently *and* uses URIs properly?
In fact, the current best practices created by the linked open data
community (and actually, the WWW architecture specs) describe a clear
path for NOT messing up
- names
- entities in reality
- meta-data describing the entities (e.g. information resources)
One of the current patterns uses http 303 redirects. It is still a bit
of a hassle to set that up properly, but it is theoretically sound and
works in practice.
See
http://www.w3.org/TR/cooluris/
What is cracked is that a some vendors of tools and infrastructure try
to mess up the clean architecture of the Web for the sake of
short-sighted simplicity. The HTML5 WG is a prominent example.

I may sound like a cracked record on this, but ISO does have a standard that includes within its spec a clean method for distinguishing between an identifier of a "thing" (whether freedom, love, Harry Poeetr and the Philosopher's Stone or the concept of an Imperial pint) and an identifier that says something about the thing, such as a document.
We know that a fundamental part of the WWW architecture is cracked - the inability to use URIs to distinguish between a name of something and an address describing that something - so why not use a standard that addresses (excuse the pun) the issue correctly, consistently, coherently *and* uses URIs properly?
I'm talking about the ISO 13250 "Topic Maps" standards and its distinction between subjects, topics, subject identifiers and subject indicators (or descriptors).

Kevin,
There may be some people who agree with you:
KDK> Is it just me who thinks that looks a whole lot better,

But the URIs as used in the Semantic Web have many serious
problems for designating standards:
1. There is no way to tell when or why whatever information
contained in a document designated by a URI might change.
2. There is no way to specify what is specified by a URI:
The document itself? Some information in the document?
What information in the document? Why? How? By whom?
Standards organizations such as ISO have considered and
addressed these issues over long periods of time. Their
universal identifiers are reliable, even though (or perhaps
because) they have been using old-fashioned paper documents
to specify them.
John
