By recent popular demand, I updated (slightly)

         http://larry.masinter.net/duri.html (and .txt and .xml)
and submitted it to the internet-drafts repository as
               
           draft-masinter-dated-uri-05.txt.

The only substantial change I made since the 2004 draft was to change the
interpretation of the date from "first instant" to "last instant", based on
a comment by Al Gilman in 2004.

Ray Denenberg asked:
> http://info-uri.info/   Have you considered 'info:' for duri and tbd?
Yes, I considered 'info:/' instead of URN namespaces. I don't think it fits
into 'info' because 'duri' and 'tdb' aren't really naming authorities in the
same way. This is more like urn:uuid:...
 
I thought about switching to plain URI schemes (without "urn:", e.g.,
uri:2008:whatever instead of urn:duri:2008:whatever), but it would be a
larger change to the draft, and require more explanation.

There's no point in 'duri' without a date. I think even 'tdb' needs a date
of interpretation, because even when resources are unchanging, the date of
interpretation matters.

The reference to RFC 2550 hints at how to solve that problem.

Harry Halpin and Tim Kindberg wrote reviews or comments in 2004
which I responded to in email, but I didn't update the document
based on their comments and my replies.
