Mediawiki

A repository allowing multiple instances that can each connect to any mediawiki site.
MediaWiki  is a  free software   open source   wiki  package written in  PHP , originally for use on  Wikipedia . It is now also used by several other projects of the non-profit  Wikimedia Foundation  and by  many other wikis , including mediawiki.org , the home of MediaWiki.
You can use this moodle repository to allow searching, linking and importing media from these wikis.
note: keep the ‘commons url’ setting blank if you don’t know or are not sure. This is a workaround for sites like wikipedia which have another (shared) url to access resources.
