2. Summary of recurrence BOF

On Monday, 10/4/10 CalConnect held a BOF session to discuss problems that different implementations have in the area of communicating and processing updates to recurring meetings. It was agreed that in general updates and reschedules to a single instance of a series works well.

Problematic use cases:

• An instance is updated/rescheduled with THISANDFUTURE (with or without prior modification)

• A series is updated/rescheduled (with no exceptional data)

• A series is updated/rescheduled and maintains some prior exception data

• A series is split, with a new UID being sent for a second half of the series: Truncation/Expansion (essentially capturing THISANDFUTURE behavior)
