ICS

The calendar feature is an advanced feature in Decision Insight. You need to purchase a license with the calendar option to use this feature.

This page describes the ICS calendar format and how to work with it to set up calendars in the product.

The Internet Calendaring and Scheduling (ics) is a universal calendar format used and supported by a large number of products, including Google Calendar, Apple Calendar, IBM Lotus Notes, Yahoo! Calendar, Evolution (software), eM Client, Lightning extension for Mozilla Thunderbird and SeaMonkey, partially by Microsoft Outlook, etc.

The ics format is designed to transmit calendar-based data, such as events, and is meant to provide the definition of a common format for openly exchanging calendaring and scheduling information across the Internet.

ICS format

The reference of ics / iCalendar format is documented in rfc2445.

ics has a wide format. We only support a subset.

In the Calendar configuration attribute type, each rule contained in the rules field must follow the following format:

  • The first line must be BEGIN:VCALENDAR, and the last line must be END:VCALENDAR; the contents between these lines is called the icalbody.
  • The body is then made up of a list of events, each beginning with BEGIN:VEVENT and ending with END:VEVENT.
  • Inside an event, we support the RRULE and EXRULE definitions.

This example schedules an event every day from noon to midnight since 1st January 2017:

BEGIN:VCALENDAR
BEGIN:VEVENT
DTSTART:20170101T120000
DTEND:20170102T000000
RRULE:FREQ=DAILY
SEQUENCE:0
END:VEVENT
END:VCALENDAR

Tools

To help you define recurrent rules you can use:

  • Outlook:
    1. Create a periodic event.
    2. Transfer it and register it locally.
    3. Re-open it as a text file.
    4. Inside the VEVENT block, copy:
      • DTSTART without the TZID produced by Outlook.
      • DTEND without the TZID produced by Outlook.
      • RRULE
      • SEQUENCE
  • RRULE Generator helps you define recurring rules via a Web form.
  • ICal Event Maker ( TZID are not supported and have to be removed from the generated content ).

Examples

These examples are copied from section 4.8.5.4 Recurrence Rule of rfc2445.

   An example where the days generated makes a difference because of
   WKST:

     DTSTART;TZID=US-Eastern:19970805T090000
     RRULE:FREQ=WEEKLY;INTERVAL=2;COUNT=4;BYDAY=TU,SU;WKST=MO

     ==> (1997 EDT)Aug 5,10,19,24

     changing only WKST from MO to SU, yields different results...

     RRULE:FREQ=WEEKLY;INTERVAL=2;COUNT=4;BYDAY=TU,SU;WKST=SU
