Data fields

Properties in printout statements should use one of the following labels, or otherwise are ignored in the resulting iCalendar. The available fields are:

  • location: the place of the event (type arbitrary, but Page would be common),
  • description: description of a single event (not suported by all tools, but useful to have more than the short page name as an event name.


Calendars work very well on most calendar tools, with the notable exception of MS Outlook up to version 2003. Only later versions of this tool can deal with calendars that have more than one event.

Calendar downloads can be used in two ways by a calendar software. Either the calendar is downloaded and imported into a local calendar, or it is subscribed to and updated regularly. In the former case, changes in the wiki will not affect the imported dates, while in the latter case changes in the wiki will be propagated to the subscriber of the calendar.
