The following event sources are defined for EventAggregator:
- GriCal
http://grical.org/s/?query=%21FSFE+{start}+{end}&view=ical ical
- GriCal-Free-Software-Events-Europe
http://grical.org/s/?query=*+!Free-Software-Events-EU&view=ical ical
- GriCal-FSFE-Fellowship-Events
http://grical.org/s/?query=*+!FSFE-Fellowship-Events&view=ical ical
To add a new source, extend the above definition list, putting the name of the source (to be used with the EventAggregator macro) as the definition title, and putting the source's URL and the format of the data provided by the source, separated by whitespace, as the definition body.
Currently, ical is the only supported format, referring to iCalendar (RFC 2445 and RFC 5545).
Events from sources for a particular view are cached in EventAggregator for a period of time. The default period of 300 seconds (5 minutes) can be changed by defining the event_aggregator_max_cache_age in the Wiki configuration, specifying a number of seconds to be used for the maximum age of a cache entry.
