[Kde-pim] Recurring entries in Calendars, with exceptions

[Shaheed Haque]

David, thanks for confirming; I expect this is based on the notion of
recurrence that is in RFCs. In principle, I assume that we could
extend the EXDATE property with an X-param. Could the programming
model for the RecurrenceRule be extended to support this? I guess
korganizer would also have to understand the additional semantics, but
being able to save and restore the data would be a first step.

Kevin, as I hinted, I suspect this is how Exchange represents things
internally. Certainly representing the innards in this way would give
complete flexibility.
