Re: [netmod] Fwd: Re: Last Call: <draft-ietf-netmod-iana-timezones-03.txt> (IANA Timezone Database YANG Module) to Proposed Standard

Hi Andy,
Hi,

By "this one" I assume you mean the question "Why Proposed Standard?"
I meant the other questions in this email, most importantly.

This YANG module is meant to be imported by other standard YANG modules,
which creates a normative reference in each importing RFC. We try to avoid
standard modules that rely on non-standard modules. At first, (e.g, RFC 5277,
RFC 5717) the YANG modules were not normative. But since 2010,
(RFC 6020) all YANG modules are normative and XSD is no longer used.
Thanks for your answer.

Regards, Benoit


Andy

    Dear all,

    Sadly, I have not seen a reply to this one.
    So let me start the discussion, copying both the ietf-discussion

    See in-line.
    Dear all,

    Here is some feedback from the IETF discussion list.
    I would appreciate if the author and document shepherd could
    follow up. Ideally on the IETF discussion list.

    There is the following question in the document shepherd write-up:

       Why is this the proper type of RFC?

    I did not see an answer to that question.
    Not sure what you propose here. Proposed Standard seems right to me.
    From http://www.rfc-editor.org/RFCoverview.html


            RFC Categories

        Each RFC has a "category" or "status" designation. The
        possible categories (see *RFC 2026*
        <http://www.rfc-editor.org/rfc/rfc2026.txt> "The Internet
        Standards Process -- Revision 3") are:

          * INTERNET STANDARD, DRAFT STANDARD (deprecated; see RFC
            6410 <http://www.rfc-editor.org/rfc/rfc6410.txt>),
            PROPOSED STANDARD

            These are /Standards Track/ documents, official
            specifications of the Internet protocol suite defined by
            the Internet Engineering Task Force (IETF)
            <http://www.ietf.org> and its steering group the IESG.

          * BEST CURRENT PRACTICE

            These are official guidelines and recommendations, but not
            standards, from the IETF.

          * INFORMATIONAL, EXPERIMENTAL

            These non-standards documents may originate in the IETF or
            may be independent submissions.

          * HISTORIC

            These are former standards that have been actively
            deprecated.

    The WGLC was from 5 July to 22 July.  There wasn't any comments
    during the WGLC.  The only comment I found was one posted on 9 August.

    In Section 1:

       "The iana-timezones YANG module defines the iana-
        timezone type, which is a serialization of the existing IANA Time
        Zone registry [RFC6557] into YANG format."

    The terminology in RFC 6557 defines a TZ Database sometimes referred
    to as the "Olson Database".  There isn't any mention of a "IANA Time
    Zone registry".  I suggest using the same name as in RFC 6557.
    That makes sense.
    >From Section 3:

       'The iana-timezones module is intended to reflect the IANA "timezone
        database" [RFC6557].  When a timezone location is added to the
        database, the "iana-timezone" enumeration MUST be updated as defined
        in RFC 6020 Section 10 to add the newly created timezone location to
        the enumeration.  The new "enum" statement MUST be added to the
        "iana-timezone" typedef with the same name as the newly added
        timezone location.  A new enum value MUST be allocated by IANA and
        applied to the newly created enum entry.  New entries MAY be placed
        in any order in the enumeration as long as the previously assigned
        enumeration values are not changed.

        If a timezone location is removed from the IANA timezone database,
        the corresponding existing enum statement is kept and a status
        statement is added to mark the enum entry as 'obsolete'.'

    The maintainer of the TZ database is responsible for the TZ
    Database.  The person does not work for IANA.
    Correct, but see BCP 175: Procedures for Maintaining the Time Zone
    Database:
    <http://www.iana.org/go/rfc6557>

        The TZ Coordinator is an IANA Designated Expert

    Are you questioning the term "IANA timezone database", which should be "TZ 
Database" according to BCP 175?

    I don't think that
    IANA keeps track of the contents of the TZ Database as it was not
    asked to do that work.
    I think it does: http://www.iana.org/time-zones
    I don't see the value of using RFC 2119 key
    word for the IANA Considerations.

    I suggest not creating the registry proposed in this draft.  The TZ
    database has strived to keep out of political issues.  Adding such a
    registry will pave the way for such issues.
    Well, we need to specify the system clock in the following YANG
    module
    (https://datatracker.ietf.org/doc/draft-ietf-netmod-system-mgmt/),
    and hence we require a way to represent the TZ in YANG.
