Plone is a free, user friendly, and open source content management system running on top of Python, Zope and the CMF.
The software is suited for an internal website or may be used as a server on the Internet, playing such roles as a document publishing system and groupware collaboration tool. It offers a good, low maintenance intranet/portal system.
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.
It benefits from all features of Zope/CMF such as: RDBMS integration, Python/Perl extensions, Object Oriented Database, Web configurable workflow, pluggable membership and authentication, Undos, Form validation, amongst many many other features. Available protocols: FTP, XMLRPC, HTTP, WEBDAV and you can hack it to enable SOAP. Turn it into a distributed application system by installing ZEO.
Plone shares some of the qualities of Livelink, Interwoven and Documentum. It aims to be *the* open source out-of-the-box publishing system.
The software ships with some basic tools and functionality, but a lot of its strength comes from the specialized applications that run inside it.
