CalDAV is an open standard for synchronising and updating calendars, and I’ve been keeping an eye on it ever since Apple quietly announced, way, way back, that it would be supported in the Leopard version of iCal, their desktop calendar program. This meant that you could publish your calendar to a CalDAV server, and that other people could also subscribe to it and update it.
This is important because, for many people, calendar synchronisation (allowing things like meeting room booking as well) is the only reason they run the expensive abomination that is Microsoft Exchange. To have broader support for an open standard would be great! But my hopes of a brave new world were moderated somewhat when implementations of CalDAV servers, other than the one Apple shipped with its server OS, seemed to be few and far between.
Well, it’s still early days and there are limitations and some rough edges – like iCal not syncing such calendars to iPhone/iTouch – but it’s a good start: with people like Google and Calgoo now creating server implementations, and iCal, Calgoo and Mozilla Sunbird (at least) supporting CalDAV on the desktop, my hope is renewed…
