TYPOlight is one of the most attractive open source content management systems I have seen.
Built with PHP5, TYPOlight uses MySQL for storing the data. Besides the powerful features, this CMS application is very well documented and has an active users community.
As a feature spotlight, XHTML output, form generator and being able to manage multiple websites under 1 system are really nice.
Radiant is an open source content management system built with Ruby on Rails. It is built for small developer teams other than the end-users as it requires programming knowledge.
With a very simple interface, Radiant offers flexibility when creating the design & content. 3 parts: pages, snippets (like PHP includes) and layouts create the core of the system.
It offers a flexible site structure where pages can be arranged according to any hierarcy.
Radiant has a custom template language named Radius (similar to HTML) which can be used inside pages, layouts to include content from other pages or display content conditionally & more. It also has an intelligent caching mechanism which helps serving pages faster while ensuring the content is up-to-date.
PureEdit is a content management system specially for developers who create the front-end of the website themselves and need a flexible CMS software.
PureEdit lets you control the databases that you created with a nice looking CMS interface without any coding. It simply lets you create, edit or delete data with database. Compared to many other CMS softwares, you don’t need to adapt to the CMS software, PureEdit adapts to you.
The beauty of PureEdit comes with the clever interface that understands whether the database column will be shown as a file upload, text editor, date, etc.. By naming the columns with _txt, _file, _date (ex: post_date) PureEdit gets that this will be a date value and shows this data as a date view.

SilverStripe is a powerful content management system which runs on Sapphire framework (object oriented framework like Ruby on Rails or Django).
The framework lets you rapidly code up the "objects" your project uses (e.g. staff members, products, customers, along with their relationships). You then add a few lines of code and find SilverStripe has automatically added tables and columns to the database, let you use them in your website templates, and has added new "page types" and fields into the CMS for the content editor to utilise.
Some features:
Simple: Intuitive and user-friendly
Flexible coding framework
Scalable: From 1 page to a million
Standards Compliant: Fully XHTML compliant
Modular
Template Freedom: No restrictions on the look and feel of your site
Open source
Cross platformeasy to install (PHP based)
Supported
One of the best things about SilverStripe CMS is the active community behind it. You can easily find support from users.
There are some very useful modules developed for this content management system including a blog module, forum module & an e-commerce module.
