Question

Answer 1

+2 A:

Following the chain of specifications, the IANA URN namespace registry does indeed register 'uuid' as a namespace after 'urn:'. So yes, the URL above is wrong and it should start 'urn:uuid' as you were expecting.

the fact is that if you search with google, you find a lot of URI like that one.

Stefano Borini 2009-10-27 05:41:48

It is still wrong, however many times you find evidence of that on the web with some search engine.

Answer 2

+1 A:

This URI is wrong. Using the following RDF document in the W3C RDF Validator returns an error

<?xml version="1.0"?>
<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
  xmlns:dc="http://purl.org/dc/elements/1.1/"&gt;
  <rdf:Description about='uuid:8949dbc6-31ad-11d9-9c7d-d112c21f7031'>
    <dc:title>Hello</dc:title> 
  </rdf:Description>
</rdf:RDF>

Error: {W102} unqualified use of rdf:about is deprecated.[Line = 4, Column = 70]

In fact, the problem comes from "rdf:about" see my comment in the header, please.

Pierre 2009-10-27 10:17:21

ah, right. unqualified of the about, not of the argument of the about.
