John

Yes, I really was replying to the adoption call, opposing adoption on
the grounds that the I-D as it stands is insufficiently precise.

I first saw IANA using 'deprecated' as a status in 2013 and this led to
a discussion on the main IETF list, that the term had been in use for a
while in SMI but that the SMI definition seemed inappropriate for the
use to which IANA were now putting it and that we needed a definition.

The then current version of
draft-leiba-cotton-iana-5226bis
was put foward as the place to define 'deprecated', IETF-wide, and
AFAIK, that has been the practice since.

So we have a definition that has been in use for three years, in the
context of IANA, which is, to quote,
"  Specific entries in a registry can be marked as "obsolete" (no longer
   in use) or "deprecated" (use is not recommended). "

I believe that this I-D cannot be understood without reference to that
definition, hence my opposition to an I-D that leaves the interpretation
of 'deprecated' up to the reader (who may assume that the SMI definition
is appropriate).

I also wonder if those agreeing to adoption still do so with that as the
meaning of the term; perhaps they do, but Robert questioned whether or
no 'deprecated' was really the right status and I am of like mind,
although my reasons may differ from his.

Subject: Re: [Idr] Working group adoption call for
draft-snijders-idr-deprecate-30-31-129


Tom,

I'm confused by your message.

It appears to relate to the proposed adoption of
draft-snijders-idr-deprecate-30-31-129 and not to my most recent message
regarding IANA process at all, even though you followed up to, and
quoted, mine. I'll proceed on that assumption.

I agree that it's unfortunate there is apparently no referenceable
definition of "deprecate" but on the other hand, this has not impeded
many code points from being deprecated in the past. Somehow we have
muddled through. I suppose it wouldn't be the end of the world to do as
you suggest and normatively reference 5226bis even if it means sitting
in downref indefinitely, because I think IANA will be willing to mark
the code points deprecated on the strength of the internet draft,
following the early (de!) allocation process. But also think it would be
fine to follow the other branch of your suggestion and quote their
definition, removing the downref.

Apart from the question of providing a reference/definition for what
"deprecate" means (which I thought we'd already settled), the rest seems
to be editorial minutiae.

None of these things (request for a definition, other editorial issues)
seems to me to be a basis for "Oppose". The question before the WG is
really "do we want to deprecate these code points", and that's what I'd
most like to see people engage with in deciding to adopt (or not) the
document.

To be clear, for purposes of this adoption call, I'm assuming we are
using the 5226bis Section 9.6 definition (or "definition") you refer to,
viz.:

   Specific entries in a registry can be marked as "obsolete" (no longer
   in use) or "deprecated" (use is not recommended).

If someone who has already responded did so on the basis of thinking
that "deprecated" means something other than "use is not recommended"
they may of course revise their position.

Regards,

--John
