Custom class mapping

Hello,
I saw in the online docs that I can create a custom class for appointments
public class Meeting   
    {   
        public string EventName { get; set; }   
        public string Organizer { get; set; }   
        public string ContactID { get; set; }   
        public int Capacity { get; set; }   
        public DateTime From { get; set; }   
        public DateTime To { get; set; }   
        public Color color { get; set; }   
    }
and map the fields in xaml
<syncfusion:SfSchedule x:Name="schedule">
        <syncfusion:SfSchedule.AppointmentMapping>
            <syncfusion:ScheduleAppointmentMapping
                ColorMapping="color"
                EndTimeMapping="To"
                StartTimeMapping="From"
                SubjectMapping="EventName" />
        </syncfusion:SfSchedule.AppointmentMapping>
    </syncfusion:SfSchedule>
but what fields should I add to the custom class for the Recurrence Pattern and how do I map them?
