Exponent CMS is a free, open source, open standards modular enterprise software framework and content management system (CMS) written in the programming language PHP.

Exponent uses an intuitive and flexible content editing system that allows website content to be edited right on the page as it appears – without back-end administration. The default installation includes a complete set of modules for managing a typical website. Additional modules are developed by a community of open source developers and can be installed via a web browser.

Exponent CMS can be installed in a Linux, Unix, Mac OS X or Windows environment, or any platform that supports the Apache web server and the PHP language (version 4.0.6+). Exponent CMS currently requires a MySQL (4.1+, 5+ Recommended) to store content and settings.

Themes

The Exponent CMS was designed from the ground up with designers in mind. As such, it is incredibly simple for someone with a little knowledge of html and css to create an Exponent CMS theme. Themes for Exponent CMS are written using html/xhtml and css. You just have to place a some hooks in your theme file to integrate Exponent CMS into your theme. That makes Exponent CMS highly flexible for designers. Any html based design can be easily converted into an Exponent theme.

In Exponent CMS content and presentation have been separated. To accomplish this the Smarty template engine was used for creation of views. Views allow the same content to be displayed in different looks and customized to match a sites theme.

Translations

Translations for Exponent CMS’s interface are available in 3 languages: English US (the default), Danish (Dansk) and German (Deutsch). The English source is managed by OIC Group, Inc. The Danish translation is managed by Elund Christensen, Jens Thomsen and Thomas B. Nielsen. The German translation is managed by Gerhard Starrermayr.
