(Cc'ing both tzdist and calsify because the issue is about the interaction
of specs defined by the two groups...please trim to one or the other if the
topic ends up being unique to that group.)

A question recently occured to me about the interaction of rscale and tzdist.

Should it be possible for a VTIMEZONE -- either inline in an iCalendar
document, or distributed by tzdist -- to use an RSCALE?

There are some natural use cases for this -- Iran uses the Persian calendar
to set its DST observances, and Israel used the Hebrew calendar from
2005-2012.  Right now the IANA tzdata just expands non-Gregorian rules to a
list of dates, but in principle, RSCALE would be a much more natural (and
compact) way of representing rules like these.

However, tzdist has no way to negotiate the use of iCalendar extensions.
Should one be defined?

For that matter, the rscale draft doesn't talk about its use in VTIMEZONE
at all (indeed, it asserts that VTIMEZONEs are always specified in Gregorian
time).  Should it?

If a time zone were indeed defined in terms of a non-Gregorian recurrence 
then it would seem reasonable to support that.

If tz data publishers actually start wantint to produce data using 
non-Gregorian rules, then we can easily define an extension to the 
capabilities response to indicate that is an option.

Actually the rscale document only mentions time zones once in Section 1 - 
and there it states that time zone rules (i.e., what comes from a 
publisher) is specified in terms of the Gregorian calendar - that does not 
imply VTIMEZONE itself is limited to Gregorian rules - just that no time 
zone data uses non-Gregorian. If you think that text needs re-wording to 
clarify that, I can certainly change it.

At this point, I think the use of non-Gregorian rules in VTIMEZONE should 
not be ruled out, but tzdist does not need to support it until we have 
publishers actually wanting to use it. Of course at that point things will 
get tricky for the publisher as they will want to keep the Gregorian rules 
around for backwards compatibility.

A New Internet-Draft is available from the on-line Internet-Drafts directories.
 This draft is a work item of the Calendaring Extensions Working Group of the IETF.

        Title           : Non-Gregorian Recurrence Rules in iCalendar
        Authors         : Cyrus Daboo
                          Gregory Yakushev
	Filename        : draft-ietf-calext-rscale-03.txt
	Pages           : 19
	Date            : 2015-01-07

Abstract:
   This document defines extensions to iCalendar (RFC 5545) to support
   use of non-Gregorian recurrence rules.  It also defines how CalDAV
   (RFC 4791) servers and clients can be extended to support these new
   recurrence rules.


The IETF datatracker status page for this draft is:
https://datatracker.ietf.org/doc/draft-ietf-calext-rscale/

There's also a htmlized version available at:
http://tools.ietf.org/html/draft-ietf-calext-rscale-03

A diff from the previous version is available at:
http://www.ietf.org/rfcdiff?url2=draft-ietf-calext-rscale-03


Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org.

Hi folks,
A new version of the draft has been posted to address Donald's recent 
comments. It also clarifies the interaction with VTIMEZONE (following up on 
recent comments by Jonathan Lennox). The changes are to the Abstract and 
Section 1 only.

Was Updates: 4791, 5546 removed from the boilerplate intentionally, or

Hi Ken,

Yes - after consultation with our AD (Barry Leiba) I decided that rscale 
does not "update" those two, but rather "extends" or "clarifies" its use 
with those specs. In the case of CalDAV it uses existing "extension" 
mechanisms (namely the presence of a new property). So I just left iCal, 
xCal and jCal in the "Updates" list since rscale does redefine the syntax 
elements in those specs in a manner that is outside of any normal extension 
mechanism that those specs provide.

(Cc'ing both tzdist and calsify because the issue is about the interaction
of specs defined by the two groups...please trim to one or the other if the
topic ends up being unique to that group.)

A question recently occured to me about the interaction of rscale and tzdist.

Should it be possible for a VTIMEZONE -- either inline in an iCalendar
document, or distributed by tzdist -- to use an RSCALE?

There are some natural use cases for this -- Iran uses the Persian calendar
to set its DST observances, and Israel used the Hebrew calendar from
2005-2012.  Right now the IANA tzdata just expands non-Gregorian rules to a
list of dates, but in principle, RSCALE would be a much more natural (and
compact) way of representing rules like these.

However, tzdist has no way to negotiate the use of iCalendar extensions.
Should one be defined?

For that matter, the rscale draft doesn't talk about its use in VTIMEZONE
at all (indeed, it asserts that VTIMEZONEs are always specified in Gregorian
time).  Should it?

Yes, I think that the rscale draft should be clarified to note that RSCALE
can appear in an RRULE in any iCalendar context where RRULE is allowed, not
just VEVENT, and in particular it can appear in VTIMEZONE.

Yes -- for tzdist I'm mostly thinking about this as an exercise to make sure
we have backward-compatible future extensibility defined correctly.  If we
understand how we would do this if it's ever needed, I think we're in pretty
good shape.

That said, I think tzdist in the meantime should have some statement saying
that RSCALE MUST NOT be used unless support for it is negotated through some
as-yet undefined mechanism.

The new text in version -03 of rscale satisfies this nicely. Thank you!

X-List-Received-Date: Wed, 28 Jan 2015 23:05:22 -0000

The chairs requested publication of the subject document, and I've
done my AD review of it.  See the review below, with points numbered
for reference.

0. I asked Donald, in his role as document shepherd, about the use of
"updates" metadata with respect to the iCalendar, xCal, and jCal
specs.  Here's his response:

> The document changes iCalendar, xCal, and jCal by performing surgery
> on the language syntax in a way not anticipated when the base
> documents were written. See the three indented one-sentence paragraphs
> at the end of Section 1. Sorry we failed to change the word "extend"
> to "change" in the first of those. That would be easy to fix.

But that's the thing: I don't believe it does.  There's nothing done
here that requires all iCalendar implementations to support it.  This
is an extension... if you don't know about the extension, then you
don't support the extension, but I don't think this qualifies as
"updates".

We've often been fluffy and inconsistent about whether we should use
"updates" for extensions, and, for example, IMAP does this
particularly badly: it's pretty arbitrary when you look at which IMAP
extensions "update" 3501, and which don't.  But we (the IESG, at
least) are trying to be more consistent about when we use that label.

If y'all have a strong objection to removing the "updates" tags, I'll
stop objecting, and see if any other ADs bring it up.

1. Section 2
Where you explain the {C} (etc.) notation, it'd probably help to be
explicitly clear that it's only for illustrative purposes, and that
{X} never appears in actual iCalendar objects.

2. Section 4
It seems funny that SKIP has a fixed default, rather than being
dependent upon the RSCALE.  For the Hebrew calendar, for example, the
default is wrong, and one always needs SKIP=FORWARD.  It seems likely
that there'll be lots of errors involved in forgetting the SKIP and
having the default be wrong for the calendar that's being used, which
will cause interoperability problems that would be avoided if the
default depended on the calendar.  (See also my comment #8 below
about Section 4.2.4.)

3. Also, I don't want to break existing implementations, but
"SKIP=YES" doesn't seem to be the right way to put it... something
parallel to "BACKWARD" and "FORWARD" would be better.  Perhaps
"SKIP=OMIT".

4. Also also, in the grammar, please make this change:
OLD
; and MUST only be present if "RSCALE" is present.
NEW
; and MUST NOT be present if "RSCALE" is not present.

(I don't think the "MUST only" construct is clear, especially to all
varieties of non-native speakers.)

5. Section 4.1
In the last paragraph, I suggest being even clearer in the final
sentence, to avoid misunderstandings on the mapping: 'In iCalendar,
this would map to months 1 through 12 with "5L" as the leap month (ICU
month 6).  ICU months 7 through 13 would map to iCalendar months 6
through 12.'

6. Section 4.2.1
It seemed odd to me at first that you were repeating the example.
Maybe explicitly saying that will make it less odd: "Consider the
Chinese New Year example above:" (and then go ahead and repeat the
example).

7. Section 4.2.2
I don't understand why this example needs the BYMONTH value, and why
FREQ=YEARLY isn't enough.  Isn't this exactly the same as the example
in 4.2.1, where "BYMONTH=1" isn't needed?

8. Section 4.2.4
Ooh, this seems completely wrong unless SKIP is redefined to be
dependent upon the calendar.  In 4.2.3, you're showing me how
SKIP=FORWARD turns 5L-08 into 6-08, but then here you tell me that the
same SKIP=FORWARD turns 2-29 into 3-01, rather than 3-29.  Of course,
that's what we want to happen, but how can I know that from the
explanation of SKIP?  More to the point, it's clear from these two
examples that the behaviour of SKIP has to depend upon the calendar
that's in effect, and trying to define it to be independent doesn't
work.

Or have I missed something?

9. Section 5
I have never understood the statement that things in iCalendar are
case insensitive, but "SHOULD be in upper case."  If they're case
insensitive, why does it matter?  And, certainly, why does it matter
at a SHOULD level?  What's this "for consistency" thing?  Does that
mean that it's nicer, when humans read it, to have things in a
consistent case?  If so, that's a fine thing to say, but it's not an
interoperability SHOULD.

10. Where you talk about CLDR alias values, you say they 'MUST be
treated as valid "RSCALE" element values.'  Of course they must, as I
presume they're syntactically valid.  The point you want is that the
aliases MUST be treated as the same calendar as what they alias, yes?

11. Section 6
I don't understand why this section is only for iTIP.  The iTIP
responses are, sure, but what to do if you encounter an RSCALE with a
calendar you don't support is not, and advice on that needs to be
given more generally.

--
I think points 2, 7, and 8 are ones that we need to sort out before I
send it out for last call.  Any others we fix now is/are/am great too.
So let's please discuss.  I'll take responses from the authors and/or
from any working group participants (and chairs) who would like to get
involved.  Obviously, changes such as what I propose in points 2, 3,
8, and 9 need to have the working group's agreement behind them, if
they are to be made.

Thanks for your review. I am at the CalConnect meeting this week so I will 
provide a detailed reply once I get back.

With apologies in advance for this brief dive into this conversation, since
I'm not currently an active member of the Calendering and Scheduling
communities. (I attended one CalConnect event years ago, in a previous
position.)

Barry Leiba suggested, in his comment number 4, pertaining to "4. Extended
RRULE Property" in http://tools.ietf.org/html/draft-ietf-calext-rscale-03,
that as a possible alternative to the second line here:

; Optional, with default value "BACKWARD",
; and MUST only be present if "RSCALE" is present.

the following wording might be clearer, especially to non-native readers:

; and MUST NOT be present if "RSCALE" is not present.

I proposed this additional alternative to Barry, in a private communication:

; and MUST NOT be present unless "RSCALE" is present.

And he kindly considered this and responded:
"Yes, your version with "unless" works too, and captures my concern in the
same way as my suggestion.  I'm equally happy with either one."

FYI,

<br>

thing done<br>
here that requires all iCalendar implementations to support it.=C2=A0 This<=

is an extension... if you don&#39;t know about the extension, then you<br>

<br>
If y&#39;all have a strong objection to removing the &quot;updates&quot; ta=

stop objecting, and see if any other ADs bring it up.<br>
<br>
1. Section 2<br>
Where you explain the {C} (etc.) notation, it&#39;d probably help to be<br>
explicitly clear that it&#39;s only for illustrative purposes, and that<br>
{X} never appears in actual iCalendar objects.<br>
<br>
2. Section 4<br>
It seems funny that SKIP has a fixed default, rather than being<br>
dependent upon the RSCALE.=C2=A0 For the Hebrew calendar, for example, the<=

<br>
(I don&#39;t think the &quot;MUST only&quot; construct is clear, especially=
 to all<br>
varieties of non-native speakers.)<br>
<br>
5. Section 4.1<br>
In the last paragraph, I suggest being even clearer in the final<br>
sentence, to avoid misunderstandings on the mapping: &#39;In iCalendar,<br>
this would map to months 1 through 12 with &quot;5L&quot; as the leap month=
 (ICU<br>

<br>
6. Section 4.2.1<br>

Maybe explicitly saying that will make it less odd: &quot;Consider the<br>
Chinese New Year example above:&quot; (and then go ahead and repeat the<br>
example).<br>
<br>
7. Section 4.2.2<br>
I don&#39;t understand why this example needs the BYMONTH value, and why<br=

<br>
8. Section 4.2.4<br>
Ooh, this seems completely wrong unless SKIP is redefined to be<br>
dependent upon the calendar.=C2=A0 In 4.2.3, you&#39;re showing me how<br>
SKIP=3DFORWARD turns 5L-08 into 6-08, but then here you tell me that the<br=

same SKIP=3DFORWARD turns 2-29 into 3-01, rather than 3-29.=C2=A0 Of course=

that&#39;s what we want to happen, but how can I know that from the<br>

Hi Barry,

in general I agree with most of your points, except for the ones below:

#2:
Having the same default value for all calendar scales at least 
guarantees consistent results among different implementations when you 
forget the SKIP value. IMHO, having per-calendar-scale default values 
adds unnecessary complexity and it's questionable if you can find 
consensus on what the default should be for various scales (I don't 
think that the CLDR has defined default skip values so far).
Also, I think the likelihood of implementing  the per-calendar-scale 
default values wrong, is probably just as high as forgetting a SKIP value.

Setting the default to "SKIP=YES" (or "SKIP=OMIT", which sounds 
reasonable to me) would be the simplest solution, because it's the 
current behavior anyway.

#7:
True, it's not necessary to specify BYMONTH and BYMONTHDAY in sections 
4.2.2 and 4.2.3. But according to RFC 5545 it's completely valid and you 
can see many rules like that in the wild.
The purpose of an example is to show how an RRULE could look like in 
real life and how you have to interpret it. To me it perfectly makes 
sense to give examples of both types of rules (i.e. with and without 
redundant BYMONTH and BYMONTHDAY parts).

#8:
The idea is: If you skip a leap month, you go forward (or backwards) by 
one month. If you skip a leap day you go forward (or backwards) by one day.
I guess that should be pointed out somewhere.

#9:
I think that part has been added after I asked about the 
case-sensitivity of the RSCALE value. In general most calendar 
applications tend to use the upper-case representation of names and 
tokens, but the CLDR calendar scale names are defined in lower case (as 
in http://unicode.org/repos/cldr/trunk/common/bcp47/calendar.xml).
I know it's just an implementation detail rather than being relevant for 
this standard, but being able to make assumptions about the case allows 
for certain optimization that wouldn't be possible otherwise. On a 
mobile device with very limited resources that can make a difference.
In this context I think "for consistency" means consistency between 
implementations, i.e. ideally all implementations would use the 
upper-case version, even though the standard doesn't enforce it (because 
most things in RFC 5545 are, by definition, case-insensitive).
I guess the same applies to the SKIP values and the "L" of leap months. 
Does this spec allow a lower case "l"?

cheers

0. I asked Donald, in his role as document shepherd, about the use of

specs.  Here's his response:

      <blockquote type="cite">

to "change" in the first of those. That would be easy to fix.

      </blockquote>
      <pre wrap="">
But that's the thing: I don't believe it does.  There's nothing done
here that requires all iCalendar implementations to support it.  This
is an extension... if you don't know about the extension, then you
don't support the extension, but I don't think this qualifies as
"updates".

We've often been fluffy and inconsistent about whether we should use
"updates" for extensions, and, for example, IMAP does this
particularly badly: it's pretty arbitrary when you look at which IMAP
extensions "update" 3501, and which don't.  But we (the IESG, at
least) are trying to be more consistent about when we use that label.

If y'all have a strong objection to removing the "updates" tags, I'll
stop objecting, and see if any other ADs bring it up.

1. Section 2
Where you explain the {C} (etc.) notation, it'd probably help to be
explicitly clear that it's only for illustrative purposes, and that
{X} never appears in actual iCalendar objects.

2. Section 4
It seems funny that SKIP has a fixed default, rather than being
dependent upon the RSCALE.  For the Hebrew calendar, for example, the
default is wrong, and one always needs SKIP=FORWARD.  It seems likely
that there'll be lots of errors involved in forgetting the SKIP and
having the default be wrong for the calendar that's being used, which
will cause interoperability problems that would be avoided if the
default depended on the calendar.  (See also my comment #8 below
about Section 4.2.4.)

3. Also, I don't want to break existing implementations, but
"SKIP=YES" doesn't seem to be the right way to put it... something
parallel to "BACKWARD" and "FORWARD" would be better.  Perhaps
"SKIP=OMIT".

4. Also also, in the grammar, please make this change:
OLD
; and MUST only be present if "RSCALE" is present.
NEW
; and MUST NOT be present if "RSCALE" is not present.

(I don't think the "MUST only" construct is clear, especially to all
varieties of non-native speakers.)

5. Section 4.1
In the last paragraph, I suggest being even clearer in the final
sentence, to avoid misunderstandings on the mapping: 'In iCalendar,
this would map to months 1 through 12 with "5L" as the leap month (ICU
month 6).  ICU months 7 through 13 would map to iCalendar months 6
through 12.'

6. Section 4.2.1
It seemed odd to me at first that you were repeating the example.
Maybe explicitly saying that will make it less odd: "Consider the
Chinese New Year example above:" (and then go ahead and repeat the
example).

7. Section 4.2.2
I don't understand why this example needs the BYMONTH value, and why
FREQ=YEARLY isn't enough.  Isn't this exactly the same as the example
in 4.2.1, where "BYMONTH=1" isn't needed?

8. Section 4.2.4
Ooh, this seems completely wrong unless SKIP is redefined to be
dependent upon the calendar.  In 4.2.3, you're showing me how
SKIP=FORWARD turns 5L-08 into 6-08, but then here you tell me that the
same SKIP=FORWARD turns 2-29 into 3-01, rather than 3-29.  Of course,
that's what we want to happen, but how can I know that from the
explanation of SKIP?  More to the point, it's clear from these two
examples that the behaviour of SKIP has to depend upon the calendar
that's in effect, and trying to define it to be independent doesn't
work.

Or have I missed something?

9. Section 5
I have never understood the statement that things in iCalendar are
case insensitive, but "SHOULD be in upper case."  If they're case
insensitive, why does it matter?  And, certainly, why does it matter
at a SHOULD level?  What's this "for consistency" thing?  Does that
mean that it's nicer, when humans read it, to have things in a
consistent case?  If so, that's a fine thing to say, but it's not an
interoperability SHOULD.

10. Where you talk about CLDR alias values, you say they 'MUST be
treated as valid "RSCALE" element values.'  Of course they must, as I
presume they're syntactically valid.  The point you want is that the
aliases MUST be treated as the same calendar as what they alias, yes?

11. Section 6
I don't understand why this section is only for iTIP.  The iTIP
responses are, sure, but what to do if you encounter an RSCALE with a
calendar you don't support is not, and advice on that needs to be
given more generally.

--
I think points 2, 7, and 8 are ones that we need to sort out before I
send it out for last call.  Any others we fix now is/are/am great too.
So let's please discuss.  I'll take responses from the authors and/or
from any working group participants (and chairs) who would like to get
involved.  Obviously, changes such as what I propose in points 2, 3,
8, and 9 need to have the working group's agreement behind them, if
they are to be made.

Hi Barry,

My comments/suggestions to select points are inline.  For the others I 
either agree with your assessment/suggestion or don't have a strong 
opinion and would be fine with any changes on those.

No objection here.

Perhaps an alternative to having a per-calendar default would be to make 
SKIP mandatory in the presence of RSCALE, thereby forcing the 
user/client to be explicit in their expectations.

Grisha (co-author) and I both have running code, but I personally don't 
have an issue with this change due to the fact that my RSCALE 
implementation in Libical hasn't been officially released yet.  I don't 
know the status of Grisha's deployment, so I will let him protest on his 
own if need be.

As you point out, BYMONTH technically isn't needed.  I had suggested 
this example to Cyrus to illustrate to readers the fact that BYMONTH can 
take a value > 12 depending on the calendar.  If you feel that 
illustrating this point isn't necessary, or feel that a better example 
should be considered, I'm fine either way.

I'd be in favor of additional text clarifying that the effect of SKIP 
depends on whether the recurrence falls on an intercalary day or month.
