Though it only got the briefest of mentions in Steve Jobs’ keynote speech this morning at the Apple World-Wide Developers Conference, the next major release of OS X (codenamed Leopard) will have a new version of iCal that supports the CalDAV standard for multi-user scheduling. This means that iCal should be able to be a client to any CalDAV compliant calendaring server, which will include Oracle Calendar and OSAF’s Cosmo, with others hopefully following suit (is anyone in Redmond listening?).
There’s also mention on Apple’s web pages of an iCal server showing up in Leopard, but the web page for that isn’t there yet – I imagine that will be a CalDAV server, which will allow other clients, including Chandler, to use that server.
And Apple has joined the CalConnect calendaring consortium, and will be helping to drive industry-wide interoperability along with the rest of the members (truth in advertising: the UW was one of the original founding members of CalConnect and I sit on the steering committee).
Great news all around!
