The working group is "closed", not "defunct". The interpretation of
"closed" is that there are no more meetings scheduled, but the mailing
list remains open for discussion of URI related-issues that are not
being addressed by other WGs.

While ratings/censorship etc. was discussed at the IETF BOF, I think
there's a URI issue that lurks here: many users would like to be able
to supply some kinds of metadata along with the rest of their

The question is really just how we might accomodate that. For example,
you might say that metadata like 'rating' belongs in a URC. But the
current URC syntaxes being proposed seem too clumsy to stick inside a

You should note that in this example, the *publisher* didn't supply
the rating. Rather, it was the person making the reference.

 <LI> <A URC="Rating: V4; URL=http://sample.gif"> A very violent picture. </A>
 <LI> <A URC="Rating: S5; URL=http://sexy.gif"> A very sexy picture. </A>

Someone else might provide a different guide to the same material
which supplied different ratings.

Right, don't encode it _in_ the URL, put it in material that goes
_with_ the URL.

Putting rating information with URLs doesn't aggrevate scaling

The rating information isn't supplied by the publisher, it's supplied
by the author of the reference.

So different authors of hotlists and index information can provide
different rating services.

Yup. Whenever you publish something with a link in it, you can put in
a rating.

Yes, this isn't priviledged information.
