Wikibase/Permissions

Overview

edit

Below you'll find information about the available permissions in Wikibase, and a tidy summary in table form.

Preliminary notes

edit
  • User rights are flags defined either in MediaWiki core's PermissionManager::coreRights (link) or in the AvailableRights property of the extension.json file (e.g., on Wikibase repo)
  • These rights are then assigned to user groups, which can be defined ad hoc in LocalSettings.php by setting a boolean value on a permission key to a given group key on $wgGroupPermissions. The default user groups are defined in DefaultSettings.php (link). Extensions can set their permissions through extension.json (e.g., on Wikibase repo)
  • Grants are collections of user rights granted to third-party software on a user's behalf without giving them full user rights. Grant permissions can be set with the $wgGrantPermissions setting (defaults) or through extension.json (e.g., on Wikibase repo).

Implementation of permissions in Wikibase

edit
  • Permissions on Wikibase are all managed through classes that implement the EntityPermissionChecker interface (link).
  • Mostly, permissions are checked in the ChangeOp classes themselves. Some permissions are checked on special pages and in API modules.

Permissions table

edit
  • User right: The permission flag being checked
  • Description: The action the permission is checked on
  • Enabled user groups: Which user group this permission is enabled for by default
  • Included in grants: Which grants (collections of permissions for third-party apps) include this permission by default
