Yesterday the first alpha version of origo has been launched. Origo is a platform for distributed development and user interaction. It is built on a middleware architecture that uses JXTA and is written in Eiffel. This middleware provides an xmlrpc api which is used by a website to access and update data.

During building of the eiffelroom site with Drupal I learned quite a lot about this CMS. First, it has a good API and a whole bunch of modules which help you build your site. Second, it does not provide everything I need.
