MediaWiki:Gwtoolset-detect-license-explanation/en-gb

The MediaWiki template may have a  parameter; when it does, an attempt to detect the copyright licence based on the metadata value can be made. GWToolset looks for Creative Commons URLs that match possible copyright licences; e.g., https://creativecommons.org/licenses/by-sa/3.0/ matches the MediaWiki licence template. If this checkbox is left unchecked, the raw metadata value for each item in the batch upload will be placed in the permission parameter.
