I've finished scanning the new standards CalWS-ReST, iCalendar 2.0 and xCal.
They look very promissing. So I want to find out, what the original intentions
and motivating problems for the Kolab XML format were.
I found the first mentioning of the format in june 2004 on kolab devel by Bo
This mail however reveals no detailed motivation why iCalendar 1.0 at that
time did not fit.
CVS however contains this enlighting doc:
Does anybody have a rendered version of this file?
It points out problems to map MS Exchange's MAPI format to iCalendar and gives
this as the motivation for kolab xml. (All evil comes from M$...)
Now the question is whether the motivation from 2004 is still true for today
with a revised iCalendar format and much better public knowledge about MAPI?
Referring to the recent discussion about XML schema and preservation of
unknown properties: iCalendar supports vendor properties either as IANA
registered properties or as x-props. Wouldn't that be enough?
