iCal4j Template - Groupware: Attendance

A useful metric to track for meetings and other events is actual attendance. Whilst opaque events provide an intention to attend, Attendance can provide a record of actual participation after the event.

Examples

For each participant in a meeting attendance may be recorded as follows:

VEvent meeting = ...
VCard attendee = ...
VJournal attendance = new Attendance().participant(new Contact(attendee))
            .start(LocalDateTime.of(2023, 11, 15, 9, 0))
            .end(LocalDateTime.of(2023, 11, 15, 9, 30))
            .context(meeting)
            .apply();

The attendance record looks something like this:

BEGIN:VJOURNAL

DTEND:20231115T093000
