Hi,
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
Thorsen: http://kolab.org/pipermail/kolab-devel/2004-June/001438.html
This mail however reveals no detailed motivation why iCalendar 1.0 at that
time did not fit.
CVS however contains this enlighting doc:
http://kolab.org/cgi-bin/viewcvs-kolab.cgi/doc/kolab-formats/Attic/kolab-file-
format.lyx
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?
