WordPress.org

Creative-Commons-Configurator had been initially released in early 2006. It is actively maintained.

This plugin is the only tool a user will ever need in order to set a Creative Commons License on a WordPress blog and control the inclusion or display of the license information and relevant metadata into the blog pages or the syndication feeds. All configuration is done via a page in the administration panel. Template tags are also available for those who need complete customization.

Features at a glance:

• Configuration page in the WordPress administration panel. No manual editing of files is needed for basic usage.
• License selection by using the web-based license selection API from CreativeCommons.org.
• The license information can be reset at any time. This action also removes the options that are stored in the WordPress database.
• Adds license information to:
  • The HTML head area of the every blog page (this is for search engine bots only – Not visible to human visitors).
  • The Atom, RSS 2.0 and RDF (RSS 1.0) feeds through the Creative Commons RSS module, which validates properly. This option is compatible only with WordPress 2 or newer due to technical reasons. It will not appear on versions older than 2.0.
  • Displays a block with license information under the published content. Basic customization (license information and formatting) is available through the configuration panel.
• Some template tags are provided for use in your theme templates.
• The plugin is ready for localization.
