This section describes the following information about Calendar Server data:
1.6.2 Import and Export of Calendar Data for Calendar Server Version 6.3
1.6.3 Calendar Links for Data Exchange in Calendar Server Version 6.3
1.6.5 Support of ITIP/IMIP Standards in Calendar Server Version 6.3
Calendar Server data format is modeled after RFC 2445, Internet Calendaring and Scheduling Core Object Specification (iCalendar).
Calendar Server supports the following formats:
XML (.xml) — The interface to Communications Express.
iCalendar (.ical) — The default format.
Calendar data can be imported and exported in either iCalendar (.ical) or XML (.xml) format. Calendar Server administrators can import and export calendar data using the Calendar Server csimport and csexport utilities. End users can import and export calendar data using the Communications Express user interface.
Calendars can be referenced as links embedded in email messages and on Web pages. Users can then click a link to view a calendar without having to log into Calendar Server, as long as the calendar allows read access. For example, the following link specifies a resource room named Auditorium:
http://calendar.sesta.com:8080/uwc/?calid=Auditorium
For information on how to link to a calendar, see 15.8 Linking to a Calendar.
Calendar Server supports server-side email alarms, which can be sent to a list of recipients. The format of the email message is configurable and is maintained as a server attribute, rather than as a user or calendar attribute.
Calendar Server supports the ITIP/IMIP standards (RFC 2446 and RFC 2447), including ITIP methods PUBLISH, REQUEST, REPLY, and CANCEL for events.
