GriCal offers its content as free content allowing its reuse by any party under the conditions of the CC-BY-SA license. Its source code is Free Software and thus respects the Open Knowledge Definition and the Open Software Service Definition of the Open Knowledge Foundation.
You can subscribe to an event (or to the result of filters) to get notified of any change, comment, or new event matching a filter.
GriCal has groups. A group consist of some users and events. Groups allows its users to create lists of events to monitor them or to offer them on another platform.

- Giving the name of a place and a distance. @london+100 would look 100 kilometers around the center of the most relevant place with the name london (being it London in Great Britain). The country can be specified with e.g. @london,ca (the most relevant city with the name London in Canada).

You can optionally include more data in the submission. Example:

The field description must be the last one and its content can contain multiple lines. The content is rendered as ReStructuredText.
A recurring event is one that happens again after a period of time. For instance a weekly or monthly meeting.
It is possible to create and edit recurrences of an event in GriCal by using the web interface: edit the event and select recurrences
It is also possible to add recurrences in GriCal by editing an event as text, but it is not possible to edit its recurrences. Example of adding two recurrences:
title: GridCalendar presentation start: 2010-12-29 tags: calendar software open-source gridmind gridcalendar web: http://example.com dates: 2011-01-01 2011-01-02
Notice that the recurrences will have the same data except for the start date, the deadlines and the sessions.
Since events can be modified by anyone, including anonymous (not logged-in) users, GriCal stores (remembers) all revisions (states) of events. All revisions of an event is called history, like the history of an entry in the Wikipedia.
Only logged-in users can delete or revert an event to a previous revision.
When an event is deleted, it is possible to indicate another event containing the information of the deleted event. Users trying to access the deleted event will be then redirected to the other one.
