[Evolution-hackers] [evolution-kolab] Datastructures for calendar data

[Hendrik Helwich <h helwich tarent de>]

Hi evolution hackers,

while working on a plugin [1] to connect eds  to a kolab server, i need to 
convert evolution contacts, events, tasks and notes to a kolab email (and 
back).
Right now the idea is to use the class EContact for evolution contacts and 
ECalComponent for evolution events, tasks and notes.
I now noticed, that an event in an evolution iCalendar file contains a 
VTIMEZONE and a VEVENT block, and the VEVENT block depends to a timezone 
which is defined in the VTIMEZONE block.
The ECalComponent seems to hold only one block of an iCalendar object and it 
is therefore not possible to get all the informations of an evolution event  
from one ECalComponent.

What would be the best datastructure to convert from/to an evolution event?
* A List of ECalComponent?
* One ECalComponent which is created from a List of ECalComponents by
  converting local time to UTC time?
* iCalendar Strings?

Regards,

Hendrik
