Mac OS Forge and Darwin Calendar Server
Apple announced a new hosting site for open source Mac-related projects at www.macosforge.org.
Of most interest to me at this moment are the Wiki Server project mentioned yesterday and the CalDAV-based Darwin Calendar Server. It’s touted as working with all standards-capable clients, like iCal, Mozilla Sunbird, Chandler, and more.
(Meanwhile, Apple has moved a number of its projects, including Darwin Calendar Server, to the Apache 2.0 license.)
