To modify the setting to this configuration parameter, add one of the following lines to your "LocalSettings.php" file after the enableSemantics() call:

Change the standard directory to store the file to the base directory of the wiki

$smwgConfigFileDir = $IP;

This means that the setup information file ".smw.json" will be stored in the base directory for the wiki2, e.g. /path/to/wiki.

Change the standard directory to store the file to a completely different directory

$smwgConfigFileDir = /usr/local/bin/smw;

This means that the setup information file ".smw.json" will be stored in /usr/local/bin/smw.

In a farmed multi wiki environment something like the following is possible, too to allow differentiating between individual wikis:

$smwgConfigFileDir = __DIR__ . "/../.config/{$wgDBname}";
