[fleXive] CMS is a Java EE content management system based on JavaServer Faces 1.2. It combines the power of JSF XHTML templating with that of the Java EE 5 content repository, [fleXive]. Some highlights include dynamic JSF templating (Facelets), easy integration of custom logic with EJB or JSF beans, a modular structure, Maven support, generic data structures, and WebDAV and CMIS support. It incorporates all core [fleXive] features like security, versioning, multilinguism, and scripting.
libposix is an impementation of the core functionality of all Unix systems. It is a full, cross-platform implementation of the POSIX 2008 standard. It is meant to replace existing implementations of a Unix system's core libraries. It is an exact implementation of POSIX 2008 and nothing else (no extensions, no previous POSIX versions). However, it works well with possible extensions to the core system functionallity (for example, GNU or BSD).
ShortPHP was designed to be the shortest, smallest, quickest Web framework possible. The code is currently less than 4KB in size and is just under 100 lines. In some ways, you could say that it follows the MVC (Model-View-Controller) paradigm, but since it has no database-related code (it is completely file-based) it's more of a VC (View-Controller) system. It's up to the developer to use whatever tools are deemed fit. ShortPHP is fully E_STRICT compliant.
