This pattern denotes the “security” scheme used by wikis in which anyone can edit any content. Experience has shown that this can be a powerful tool in conjunction with the Selective Rollback pattern.

Turn off all permissions on the wiki, except those having to do with rollback. Allow any user to perform any action on behalf of the site.

The original http://c2.com considered this a key aspect of wikis.

• This pattern is an instance of Clean Permissions .
