This makes a lot of sense.

Who would be that will executor? In the case of public sector websites, 
presumably the relevant national archive? Is there a business model here 
I wonder ;-)

As for top level domains, some are more politically acceptable than 
others of course. Perversely perhaps, it seems that a vocabulary hosted 
on example.eu, example.us or example.gov.uk might face more resistance 
to uptake than example.ie or example.ly, especially if it spelled out a 
nice word like semantical.ly (which appears to be available btw).

What we're talking about is maintaining a set of URIs for the long term 
for vocabularies. For documents and Web content in general, an archivist 
might take a different view. Britain's National Archives can, 
legitimately, say that, for example, the Bercow Report of July 2008 is 
still publicly available online. It's at:

http://webarchive.nationalarchives.gov.uk/20080528125538/http://www.dcsf.gov.uk/bercowreview/docs/7771-DCSF-BERCOW.PDF

The issue though is that it used to be at
http://www.dcsf.gov.uk/bercowreview/docs/7771-DCSF-BERCOW.PDF

and if anyone had linked to the original URI then someone following that 
link would see a short HTML page explaining at the dcsf.gov.uk site is 
no longer in operation, where the current live version is, and where the 
archive is. That's a very basic message for humans and no message at all 
for machines.

Hmmm... Given that the original URI of the doc is preserved within the 
new one, it shouldn't be too hard to come up with a script that 
automatically gave a 301 redirect *if* the target gave a sensible 200 
response and a helpful message in case the target lead to a 404?

Phil.
