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 having been held in 2003 and nine 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, 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 counsel from the Software Freedom Law Center.
The Plone project began in 1999 by Alexander Limi, Alan Runyan, and Vidar Andersen. It was made as a usability layer on top of the Zope Content Management Framework. The first version was released in 2001. The project quickly grew into a community, receiving plenty of new add-on products from its users. The increase in community led to the creation of the annual Plone conference in 2003, which is still running today. In addition, "sprints" are held, where groups of developers meet to work on Plone, ranging from a couple of days to a week. In March 2004, Plone 2.0 was released. This release brought more customizable features to Plone, and enhanced the add-on functions. In May 2004, the Plone Foundation was created for the development, marketing, and protection of Plone. The Foundation has ownership rights over the Plone codebase, trademarks, and domain names. Even though the foundation was set up to protect ownership rights, Plone remains open source. On March 12, 2007, Plone 3 was released. This new release brought inline editing, an upgraded visual editor, and strengthened security, among many other enhancements. Plone 4 was released in September 2010. Up to September 2007, there have been over 200 developers contributing to Plone's code. Plone won two Packt Open Source CMS Awards.
