The Open Source Applications Foundation (OSAF) has been working on Chandler for quite some time and recently released version 0.6 with basic calendaring functionality. The user interface is quite nice and provides for viewing single or multiple calendars with color-coding to differentiate between them. OSAF is also working on a calendar server to provide group calendaring functionality. The current release supports the import and export of iCalendar files and the ability to publish a read-only calendar for multiple viewers (see Figure 5).
Figure 5 Chandler imports iCalendar files such as sporting events from your favorite team.
One of the unique features about Chandler is that it is written in the open source language Python and has a plug-in architecture allowing anyone to add to the functionality. One of the primary goals of Chandler is the support for multiple operating systems. The current 0.6 release is available on Linux, OS X, and Windows XP.
