Content management system



Plone is a free and open source content management system built on top of the Zope application server. Plone is positioned as an "Enterprise CMS" and is most commonly used for intranets and as part of the web presence of large organizations. High-profile public sector users include the U.S. Federal Bureau of Investigation, Brazilian Government, United Nations, City of Bern (Switzerland), New South Wales Government (Australia), and European Environment Agency. Plone's proponents cite its security track record and its accessibility as reasons to choose Plone.

Plone has a long tradition of development happening in so called sprints, in-person meetings of developers over the course of several days; the first being held in 2003[5] and 9 taking place in 2014. The largest sprint of the year is the sprint immediately following the annual conference. Certain other sprints are considered strategic so are funded directly by the Plone Foundation,[6]although very few attendees are sponsored directly. The Plone Foundation also holds and enforces all copyrights and trademarks in Plone, and is assisted by legal council from the Software Freedom Law Center.
