I'm thinking about revising

(1) to get rid of "duri" and just stick with "tdb"
  (because there isn't much use for duri at all)
(2) make it a URI scheme rather than a URN namespace
(3) make the date optional, for cases where the time of
  binding resource to representation (and of interpretation
  of that representation to an 'abstract concept')

So the simplest form would be


which would neatly allow using descriptions of
abstract concepts to identify the abstract concept.
(Syntactically, the date can be left out without

Would this be helpful, at least for illustrative purposes?

I think there are other means for distinguishing
between the representation of a  description and 
the thing described, but this would at least
add a well-known method that isn't tied to
any particular protocol, linking method, resolution
method, etc.


might be a simple inline way of talking about the
'host' named 'larry.masinter.net'.

Quibble: In the case of a chair, you can't get metadata, since a chair
isn't data.

This is why it's nice that Eran calls the description resource a
"description resource" instead of a "metadata resource". LRDD is a
compatible alternative to linked-data 303 nose-following, one that
(like 303, as David Booth has pointed out) behaves uniformly without
caring whether the resource is "data"-like or not - it means you don't
have to ask or answer that question. I advocate using his terminology.

Perhaps an alternative to a new URI scheme for hosts would be loop
detection inside of LRDD? I think that's close to what you're saying.
