Help:List of configuration parameters

From semantic-mediawiki.org

Semantic MediaWiki offers a number of configuration parameters that site administrators may modify according to the particular needs of their wiki. This page lists all 154 configuration parameters for Semantic MediaWiki. All available configuration parameters can also be found in the file "DefaultSettings.php" (as of Semantic MediaWiki 2.4.0Released on 9 July 2016 and compatible with MW 1.19.0 - 1.27.x. and later).

To change the setting of any configuration parameter, copy the respective assignment into your "LocalSettings.php" file, after including Semantic MediaWiki as described in installation. Do not change the "DefaultSettings.php" file directly, as your changes would be overwritten in software upgrades. See also the help page on the function enableSemantics.

This list currently only covers the configuration parameters which are documented on individual pages. See this page for a complete overview by purpose.
