Plumi is a free software video sharing content management system based on Plone and primarily developed by the Indo-Pacific based EngageMedia, the Greece based consultancy, and others.[1][2] Plumi allows users to create a video sharing site by adding it to an existing Plone instance. The software includes a wide array of functionality to facilitate video distribution and community creation.[3][4]

Plumi is one project that aims to help establish "community controlled, noncommercial, free and open source alternatives" to commercial video sites such as YouTube.[5] It is designed to allow communities and "citizen publishers create their own video-sharing communities out of the box"[6] It is also designed to be more accessible to non-profit groups and independent journalists, given it is available as free-software without cost.[7]


Plumi for Plone 2[edit]

Plumi was first developed for Plone 2 by EngageMedia, with the first stable version released in September 2007, produced by EngageMedia and developed primarily by Andy Nicholson of Infinite Recursion and Dave Fregon of NetAxxs.[8][9]

The second major release occurred on February 8, 2008. By this time several organisations and projects had installed Plumi to create their own video-sharing websites, including the World Social Forum TV, Bonn University Africa on TV and CabTube.[10]

Plumi for Plone 3[edit]

Version 3.0 of Plumi is based on Plone 3 and was deployed on May 19, 2010.[11] The latest production version is 3.1.2 that was released at the end of November, 2010.[12]

Plumi for Plone 4[edit]

A final stable release of Plumi 4.0 for Plone 4.0 was released on January 17, 2011.[15] This version includes bug fixes and improvements to ensure a stable release primarily focused on rebasing Plumi on Plone 4, in addition to other improvements and re-factoring of Plumi including new production and development buildouts located inside the egg, updating the caching system, cleanup of installation code and moving parts to GenericSetup, replacing older products with newer and better maintained products or removing dependencies and other improvements. FFmpeg and codecs required by the transcoding framework are also now included in the buildout which means a simpler installation process.

A beta of Plumi 4.3 was released on December 4, 2011.[16] The beta includes updating to Plone 4.1.2, support for 16:9 video transcoding, WebM transcoding, replacement of Flowplayer with mediaelement.js HTML5 player, video language added to metadata and support for the Amara platform. A final version of 4.3 was released in January 2012.[17]

Plumi 4.3.1 Final was released in April 2012.[18] This includes minor improvements to the backend and user interface.

Plumi 4.5 Final was released in January 2013.[19] 4.5-final is a big stable production-ready release, including big improvements in both the user-interface and the back-end. Major changes in 4.5 centered around the creation of a new Plumi skin using Diazo, replacing Gunicorn with uWSGI, implementation of Amara subtitling engine and a video upload progress bar. Other improvements included removing views/downloads from the iframe for embedding, update to latest mediaelement.js and fixing of fullscreen playback. 4.5-final includes some changes after the beta include numerous improvements to the new Plumi skin, re-ordered user menu, removal of callouts folder and improved video upload stability.
