History
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.[8] 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.[9] Plone 4 was released in September 2010.[10] There are over 450 developers contributing to Plone's code. Plone won two Packt Open Source CMS Awards.[11]

Design
Plone runs on the
The name Plone comes from a band by that name and "Plone should look and feel like the band sounds".[19]
Languages
Plone is built on the Zope application framework and therefore is primarily written in Python but also contains large amounts of HTML and CSS, as well as JavaScript.[20] Plone uses jQuery as its Javascript framework[21] in current versions, after abandoning a declarative framework for progressive enhancement called KSS.[22] Plone uses an XML dialect called ZCML for configuration, as well as an XML based templating language, meaning approximately 10% of the total source code is XML based.[20]
Add-on products
The community supports and distributes thousands of add-ons via company websites but mostly through PYPI and www.plone.org. There are currently 2149 packages available via PyPI for customizing Plone.[23]
Since its release, many of Plone's updates and add-ons have come from its community. Events called Plone "sprints" consist of members of the community coming together for a week and helping improve Plone. The Plone conference is also attended and supported by the members of the Plone community. In addition, Plone has an active IRC channel to give support to users who have questions or concerns. Up through 2007, there have been over one million downloads of Plone. Plone's development team has also been ranked in the top 2% of the largest open source communities.
Strengths and weaknesses
A 2007 comparison of CMSes rated Plone highly in a number of categories (standards conformance, access control, internationalization, aggregation, user-generated content, micro-applications, active user groups and value).[24] However, as most of the major CMSes, including Plone, Drupal, WordPress and Joomla, have undergone major development since then, only limited value can be drawn from this comparison. Plone is available on many different operating systems, due to its use of platform-independent underlying technologies such as Python and Zope. Plone's Web-based administrative interface is optimized for standards, allowing it to work with most common web browsers, and uses additional accessibility standards to help users who have disabilities. All of Plone's features are customizable, and free add-ons are available from the Plone website.
Focus on security
Mitre is a not-for-profit corporation which hosts the Common Vulnerabilities and Exposures (CVE) Database. The CVE database provides a worldwide reporting mechanism for developers and the industry and is a source feed into the U.S. National Vulnerability Database (NVD).[25] According to Mitre, Plone has the lowest number of reported lifetime and year to date vulnerabilities when compared to other popular Content Management Systems. This security record has led to widespread adoption of Plone by government and non-governmental organizations, including the FBI.[2]
The following table compares the number of CVEs as reported by Mitre. Logged CVEs take into account vulnerabilities exposed in the core product as well as the modules of the software, of which, the included modules may be provided by 3rd party vendors and not the primary software provider.
CMS | First released | CVEs |
---|---|---|
Plone | 2003 | 89[26] |
Joomla | 2005 | 1230[27] |
Wordpress | 2003 | 2629[28] |
Drupal | 2001 | 1074[29] |
