Manual:$wgRightsUrl/en

Details
Set this to specify an external URL containing details about the content license used on your wiki. It's set at install time by the installer, either from its own predefined list or from the data returned from the Creative Commons license chooser.

If  is set then this setting is ignored.

This setting is used in several places, most notably to automatically generate the footer (see  for details) and in API:Meta output.

In MediaWiki 1.8.2, it appears that $RightsUrl governs portions of the Creative Commons metadata generated within $CreativeCommonsRdf in file $Metadata regardless of whether $RightsPage is set or not.
