Hi Peter,
   thanks for your feedback and for notifying us that "lex" namespace is already in the "urn.arpa" domain.

As for the "uri.arpa" domain, actually it was a mistake of mine: my request would have been for the "urn.uri.arpa" domain, as requested by Amanda Baber (IANA Operations Manager) (see below).

This need is also reported in the "lex" draft at Section 12
https://datatracker.ietf.org/doc/draft-spinosa-urn-lex/

If I well understood, the update of the NAPTR records is to be reflected in the draft at Section 12 too (according to Eliot's request). If this is the case, we will update the draft accordingly and upload a new version soon.

Best
   Enrico

Subject: [IANA #1298511] Conflict Review requested for draft-spinosa-urn-lex
 
(BEGIN IANA COMMENTS)

IESG/Authors/ISE:

IANA will need the authors to take action before we can complete the registrations for draft-spinosa-urn-lex-21. It should also be noted that the public mailing lists meant to review those registrations may not have many active members.

We understand that this document will require three IANA actions: 1) updating the reference for the existing "lex" registration at https://www.iana.org/assignments/urn-namespaces, 2) adding a NAPTR record to the urn.arpa domain, and 3) adding a NAPTR record to the urn.uri.arpa domain.

However, according to RFC 3405, in order to add records to urn.arpa and uri.arpa, the authors must submit their requests to these mailing lists for a two-week public review:

https://mm.icann.org/mailman/listinfo/register-urn
https://mm.icann.org/mailman/listinfo/register-uri

Because those lists (which haven't seen much activity post-2011) currently have ~20 members each, we've sent informal review requests to Leslie Daigle and Ted Hardie. We haven't heard from Leslie yet, but Ted had these notes:

> My quick scan of this sees a few potential issues with things listed
> as SHOULD which I believe would be better as MUST; I was also a little
> confused by this:

> in UTF-8 code to a DNS query, clients MUST perform any necessary
> punycode conversion [RFC5891] before sending the query."

There are no designated experts for urn.arpa or uri.arpa, so unless the IESG instructs us otherwise, we'll mark this document "IANA OK" two weeks after the authors submit their review requests, provided that the lists don't raise any of the objections described in Section 5 of RFC 3405.

Best regards,

Amanda Baber
IANA Operations Manager

Ciao Enrico,

I'm not an expert on the process for adding NAPTR records to the
uri.arpa domain, but if I recall correctly (and based on a quick
re-reading of RFC 3405), this domain is reserved for URI schemes.
However, there is no `lex` URI scheme, so I don't immediately see how we
could add `lex` to uri.arpa.

On the other hand, your request to register a NAPTR record in the
urn.arpa domain seems perfectly legitimate, since we've already added
`lex` as a formal namespace ID in the URN namespaces registry. [1]

Peter
