Products.Calendaring is a simple calendar implementation for CMF/Plone, which does all sorts of really cool stuff. It is made to be modular and gives a great out-of-the-box experience.
Here are some key features of "Products.Calendaring":
· Import/Export of iCal events
· Hooks PUT_Factory so you can put events with DAV/FTP.
· NOTE: This works very well with Publishing feature with OSX's iCal application.
· calendar_export is subscribable from iCal
· Reliably exports events for KOrganizer, iCal and Outlook
· There is a proper Calendar object which can store Events.
· Over 60 unit tests that cover almost all of the functionality REQUIRES: ZopeTestCase from http://sf.net/projects/collective
· Plone CMS
