Plone (software)

Plone is a free and open source content management system built on top of the Zope application server. In principle, Plone can be used for any kind of website, including blogs, internet sites, webshops and internal websites. It is also well positioned to be used as a document publishing system and groupware collaboration tool. The strengths of Plone are its flexible and adaptable workflow, very good security, extensibility, high usability and flexibility.

Plone is released under the GNU General Public License (GPL) and is designed to be extensible. Major development is conducted periodically during special meetings called Plone Sprints. Additional functionality is added to Plone with Products, which may be distributed through the Plone website or otherwise. The Plone Foundation holds and enforces all copyrights and trademarks. Plone also has legal backing from the council of the Software Freedom Law Center.

MediaWiki's "Monobook" layout is based partially on the Plone style sheets. High-profile public sector users include the Federal Bureau of Investigation, Brazilian Government, United Nations, City of Bern (Switzerland), New South Wales Government (Australia), and European Environment Agency.
