Maybe you already know it, but there's a standard 4 calendars, and a new 
iCalendar or something like that now. M$ is using the older standard, and it's
very easy to read. You should find enough info on the net.
Jetspeed (xml.apache.org/jetspeed) has it integrated I guess; I heard they want
to build the new Jetspeed on Cocoon, maybe you can collaborate. :-)
