Prior to Semantic MediaWiki 3.0.0Released on an unknown date and compatible with MW 1.27.0 - 1.30.x. it was called $smwgSparqlDatabaseConnector.1 Moreover the default setting was changed to "default" in Semantic MediaWiki 3.0.0Released on an unknown date and compatible with MW 1.27.0 - 1.30.x..2 See this version of the documentation available for releases prior to Semantic MediaWiki 3.0.0Released on an unknown date and compatible with MW 1.27.0 - 1.30.x..

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

Important noteImportant Note: If you change the setting for this configuration parameter, please ensure to run maintenance script setupStore.phpAllows to set up the data backend/store followed by maintenance script rebuildData.phpAllows to rebuild all the semantic data for a selected data backend/store.


Change to a "Blazegraph" sparql database as data backend
$smwgSparqlRepositoryConnector = 'blazegraph';
Change to a "Custom" sparql database as data backend
$smwgSparqlRepositoryConnector = 'custom';

→ This value used to be set as a legacy setting until Semantic MediaWiki 3.0.0Released on an unknown date and compatible with MW 1.27.0 - 1.30.x. to allow for existing wikis using SPARQL stores setup prior to Semantic MediaWiki 2.0.0Released on 4 August 2014 and compatible with MW 1.19.0 - 1.24.x. to work without changes. In case this setting maintained, configuration parameter $smwgSparqlCustomConnectorDefines the SPARQL custom database connectors must be set to contain the name of a custom class connector.

→ It is strongly recommended to assign the necessary connector to this parameter to one of the predefined settings in order to avoid arbitrary class assignments in configuration parameter $smwgSparqlCustomConnectorDefines the SPARQL custom database connectors, which can change in future releases without further notice.
