Adaptive Website Framework (AWF) is a modern content management system and development framework. Most of its code is object-oriented and very easy to extend. It features support for multiple Web sites and languages, content versioning, caching, community portal functions (online list, forums, instant messages, newsletters, weblogs, wiki, etc.), image upload and galleries, a lexicon, a modular full-text search engine, an auto repair function for database tables, XML and PDF export, and RSS and LDAP support. Changes can be made on a preview site and published at a later time on the live site. Fully flexible URLs allow the replacement of existing static Web sites.
Beryo is a Web content management system. It outputs valid XHTML and CSS 2.0, and its backend is very intuitive. It features a very simple system of publication, a file cache system, several existing modules (such as forum, agenda, news), internationalization, and basic monitoring. Beryo tries to be as simple as possible but keeps a high level of configurability.
BoreWiki provides a Web form interface to edit reStructuredText formatted text and creates static (X)HTML pages out of it. It provides password-based user authentication, and has directory-based access control for these users. All edited and saved pages are stored in RCS files if there is need to access old content.
CMME (Content Management Made Easy) is a Web content management system that aims to be easy to use, doesn't have many requirements, and is still reasonably flexible. It doesn't need a database, doesn't have extensive administrative needs, and works more or less like a wiki. New pages can be made on the fly, rather than through an administrative page.
Devalot is a social networking application centered around software projects. It connects the user community with the development community and encourages participation and communication. It includes all the features you've come to expect in modern Web-based applications such as tagging, comments, and a wiki, as well as features you'd expect in project tracking software such as ticketing. It has features similar to some of those found in Trac, Collaboa, GForge, Mephisto, and Typo.
Dokeos is a Web application to manage learning and collaboration activities. It allows the teacher/trainer to create content, to structure activities along a sequenced path, to interact with students/trainees, and to follow their progress. It has been translated into 31 languages, and is used by more than 3500 organizations worldwide.
DokuWiki is a standards-compliant, simple-to-use Wiki mainly aimed at creating documentation of any kind. It is targeted at developer teams, workgroups, and small companies. It has a simple but powerful syntax which makes sure the datafiles remain readable outside the Wiki, and eases the creation of structured texts. All data is stored in plain text files, so no database is needed
