Could "Task" be divided to sub-task?

[LU Wei]

I feel that the "task" feature of Lightning is too simple. A task may
contain many sub-tasks, which may have relationships of dependency of
one after another, or could be done in parallel. How to add such a new task?

The link catches me into a mess... I think you are talking about another
calendar software.

An alternative reference to the post:
<http://www.ietf.org/mail-archive/web/calsify/current/msg00034.html>

Whilst Adrian Apthorp refer to TaskCal and jBPM, more broadly his post
is addressed to the IETF calsify list. <http://www.ietf.org/
html.charters/calsify-charter.html> to see the description and charter
of the Calsify Working Group.

Ideally, anything that Sunbird/Lightning does with (or around) VTODO
should be in line with standards.

With the help of wikipedia I have some idea of what you are talking about:
icalender is a protocol standard of calender format, VTODO is a module
of icalender which correspond to the "task" part, and IETF calsify is a
group working on the standard. And Thunderbird as a realization of
icalender should be comply with it. Then my question should be whether
icalender vtodo support sub-task as I said. So Does it?

From my interpretation there is no definition about sub-tasks with the
standard definition. The "todo" is defined here:
http://tools.ietf.org/html/draft-ietf-calsify-rfc2445bis-07#section-3.6.2

With a quick look you will not see any parameter which defines such a thing.
So "Thunderbird as a realization of icalender" or better "Lightning as
a realization of icalender" or any other iCalendar realization just
going with the standard doesn't have such sub-tasks.

Also the rfc definition allows some "X-" item to extend the individual
implementation. But that would be very "Lightning" specific and not
supported with other iCalendar implementations.

Hope it helps.

Thank you. It is a depressive news; I wonder why they not giving it any
consideration, the situation which need a task be analysed is quite
general. Do you have connection with people of that group? Maybe some
suggestion could be issued.

Calendar Project <http://www.mozilla.org/projects/calendar/> has more
than enough to keep itself busy :-) and we need not be depressed that
the current feature set of Sunbird/Lightning does not extend to
project management-like concepts:

Beyond Calendar Project, there may be projects/groups that work on
standards relating to such things.

I should welcome developments, but I don't know whether Calendar
Project is the likeliest place.

You mean Calendar is designed to be a light-weight product that is to be
used just as a scrapbook or refrigerator notes?
So what should I look for?

There already exists an enhancement request for this feature since
2003: <https://bugzilla.mozilla.org/show_bug.cgi?id=194863>. Like
many other features it just misses a volunteer who wants to work on
Sunbird/Lightning development. Unfortunately Sunbird/Lightning does
not attract as many application developers or extension developers
as Firefox/Thunderbird does.

[LU Wei]

I thought there should be such request before. I have voted for this bug
to be fixed. Let's vote!

A minor point: there are more recent drafts,

As Ssitter noticed Bugzilla has bug 194863 for subtasks
https://bugzilla.mozilla.org/show_bug.cgi?id=194863
rfc 2445 already has a "related to" - property which should or could
be used for subtasks:
http://tools.ietf.org/html/draft-ietf-calsify-rfc2445bis-10#section-3...

So there is a partly working patch already...
