Development

The Plone Information Management System

Version 1.0 of the Plone Information Management System has been announced, Version 1.0.1 was released on February 17, 2003.

Plone is built on top of the Zope web application server and Zope's content management system. According to the Plone web site: "Plone is ideal as an intranet server, as a document publishing system and as a groupware tool for collaboration between separately located entities. A versatile software product like Plone can be used in a myriad of ways." Plone works on top of Linux, Windows, Mac OSX, and other Unix varients.

Plone has administrative workflow, multimedia, metadata, integrated search, and a standards-compliant templating system. Add-ons to plone provide integration with Microsoft Word, OpenOffice, PDF generation, and versioning.

One important emphasis in the design of Plone has been to achieve a quick and easy installation experience. Also, "the focus of Plone is to provide value at every level of an organization." To see what people are doing with Plone, take a look at the Plone Sites page. The main Plone Site is also running under Plone.

Plone is being developed by the non-profit organization, Plone International. The software is dual-licensed, it is available under the GPL and a commercial license.

More information can be found on the Plone Documentation page, and in the The Plone Book. If you are interested in helping out with Plone, the Development Overview is a good place to start.
