[Uri-review] Fwd: [Fwd: Registration of 'oid:' as a URI/IRI scheme]

[Lisa Dusseault <[e-mail]>]

Hi Larry, Martin, Graham,

Graham, I haven't seen your response to John Larmouth's request for review
on the 'uri-review' list.  Did I miss it?

Larry & Martin, since this particularly involves IRI syntax, I would
appreciate a review from one of you, particularly with an eye to the
comparison function.  The current description for comparison seems to
include a DNS lookup which might be problematic in many use cases.  The
encoding is also "normally" UTF-8, but I believe that requires a bit more
explanation for when an agent gets a OID IRI in one encoding, and needs to
compare it to an IRI in another encoding.

It's also not clear to me in what cases a oid IRI might use numbers in
arcids, and where it might use strings with unicode characters.  I probably
don't understand OIDs well enough, but the description so far makes me think
that these are substitutable -- again providing problems for a comparison
function.

Next, if these are intended to be more human-friendly than the numerical
representations, how are bidi characters to be displayed?

John, Is there any requirement to compare OID URNs (urn:oid:*) to OID IRIs?
If not, this should be mentioned as being not desired.

If these questions have already been answered in the discussion on
uri-review,  I must have missed that.  I believe Alfred raised very similar
questions in Dec 2008 and I did not see answers in the spec or on the list.

Thanks,
Lisa

Lisa and Alexey,

The following request for IANA registration has been made following earlier
discussions in uri-review.

It was originally intended to request "permanent", but Ira said that this
was not normal and that we should request "provisional". Alred HÎnes
responded saying that as it is based on an existing ITU-T Rec. X.660 |
ISO/IEC 9834-1,
an immediate request for "permanent" might be better.

The current request to IANA is for "provisional", but presumably this could
be upgraded if you were to recommend that?

Whether "provisional" or "permanent", it would be helpful if you could give
the proposed IANA registration your support for rapid progression.

Thank you.

John L

I refer to the Internet Draft draft-larmouth-oid-iri-03.

I would like IANA to register 'oid:' as a "permanent" URI scheme,  with the
registration template given in the 'IANA considerations' section
of the Internet Draft draft-larmouth-oid-iri-03.

This request is on behalf of the ASN.1 group, which is collaborative work
between ITU-T SG 17 Q.12 (I am the Rapporteur) and ISO/IEC JTC 1/SC 6 WG 9
(I am
the Convenor).

I understand that a "provisional" registration would be approptiate until
the
I-D reaches a certain stage of processing, but the target is "permanent" (so
an
early progression to "permanent" would be good), as the scheme is based on
existing ITU-T Recommendations and ISO Standards that are stable.

There has been review of earlier drafts by uri-review, with no adverse
comments
that have not been addressed, but I understand that you will appoint your
own
expert for a further review.

I will contact the Area Director shortly to alert her to this request.

Thank you.

John L
