What’s the best way to model recurring events in a calendar application? [closed]

I would use a ‘link’ concept for all future recurring events. They are dynamically displayed in the calendar and link back to a single reference object. When events have taken place the link is broken and the event becomes a standalone instance. If you attempt to edit a recurring event then prompt to change all future items (i.e. change single linked reference) or change just that instance (in which case convert this to a standalone instance and then make change). The latter cased is slightly problematic as you need to keep track in your recurring list of all future events that were converted to single instance. But, this is entirely do-able.

So, in essence, have 2 classes of events – single instances and recurring events.
