Events

Components

• Event
• EventOccurrence
• EventOccurrenceChange

Event

• Also referred to as parent event, because EventOccurrences are generated from Event entries.
• Event can be recurring and contains rrule(s)

EventOccurrence

• Individual event that's generated from the associated potentially recurring parent event object.
• Future EventOccurrences need to be regenerated if the parent Event's timing changes. If the start_time of the new occurrence matches an old one, any changes from the old occurrence will be transferred to the new occurrence before the old one is deleted.
• event and start_time fields are used for syncing/reconnecting new EventOccurrence objects/rows to existing EventOccurrenceChanges when they're regenerated from the parent Event. The corresponding EventOccurrenceChange object has the same fields.

EventOccurrenceChange

• Contains user-modified event data fields for an EventOccurrence that correspond to the parent Event's fields. Unchanged fields will be null.
• event and start_time are special fields used for syncing/reconnecting these changes to new EventOccurrence objects/rows when they're regenerated from the parent Event. The corresponding EventOccurrence object has the same fields.
