This tool is used to manage copyright licenses within plone. It allows for both a site wide copyright license to be set by default, and the ablility to set licenses on individual objects. It supports a number of licenses including all rights reserved, GFDL, and Creative Commons (with an integrated license picker). You can also enter and select licenses not supported by default, or configure new licenses that will appear in the selection widget for your Plone instance.

Project Description

Content Licensing Tool

by enPraxis

This tool is used to manage copyright licenses within plone. It is a product built in response to PLIP #136.

What's New

  • Added Recursive Licensing for folders.
  • Added default support for Creative Commons 3.0 licenses
  • Updated UI to clarify default site settings for end user.
  • Fixed a bug that did not render the licensing RDF for Creative Commons Licenses.


This product no longer relies on the DublinCoreExtensions Addon. Simply unpack the product in your products directory, restart Zope, and use the quick installer via the "Site Settings/Add/Remove Products" link to install it.

If you are upgrading an existing ContentLicensing product from a previous version please see additional instructions contained in the INSTALL.txt file.
