Campsite is a free and open source multilingual content management system for news websites. Its localizable user interface was built with journalists, editors and publishers in mind, rather than computer experts, and it can be configured to suit different profiles of end users. Campsite follows a newspaper publishing model, so it structures sites by default as Publications, Issues, Sections and Articles, rather than nodes or objects. Campsite is intended for medium-to-large-size online news publications, but it can be used to manage content for smaller sites too. Campsite allows the management of multiple journalists and publications from a single interface.
