$smwgSparqlQueryEndpoint is a configuration parameter that is used to set the endpoint (service URL) for querying (reading queries like SELECT) the semantic data store when using a SPARQL database. The parameter was introduced in Semantic MediaWiki 1.6.0Released on 30 July 2011 and compatible with MW 1.15.x - 1.18.x..

Semantic MediaWiki 2.5.0Released on 14 March 2017 and compatible with MW 1.23.0 - 1.29.x. brought a performance setting allowing to redirect the query answering to the relational data backend instead so that surges of SPARQL queries can be avoided.1

No longer functional as of Semantic MediaWiki 7.0.0Released on 4 June 2026 and compatible with MW 1.43.x - 1.46.x.. The runtime shim that automatically translated $smwgSparqlQueryEndpoint to its replacement has been removed, so this setting is now silently ignored. Migrate to configuration parameter $smwgSparqlEndpointNo description was provided. (key 'query') in "LocalSettings.php".2

Default setting[edit]

$smwgSparqlQueryEndpoint = 'http://localhost:8080/sparql/';

This means that localhost is used as query location.

Changing the default setting[edit]

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

Defining a different query endpoint
$smwgSparqlQueryEndpoint = 'https://localhost:8080/query/';
Disable the SPARQL endpoint and redirect queries to the relational data backend
$smwgSparqlQueryEndpoint = false;
