Community Contributed Collection (CoCoCo) is web software developed by the RunCoCo Project at the University of Oxford for collecting, cataloguing and managing web content such as text or uploaded files contributed by a community of users. It enables administrators to assess contributions for quality, approve project-appropriate contributions, and apply metadata where required. Once a contribution is approved, it is available for searching and browsing through the provided interface. CoCoCo utilizes Ruby on Rails, and is available under an Open Source version 3.0 license.
