$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 an unknown date unknown versions of MediaWiki.

Semantic MediaWiki 2.5.0Released on an unknown date unknown versions of MediaWiki 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

Default setting

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

This means that localhost is used as query location.

Changing the default setting

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

Defining a different query endpoint

$smwgSparqlQueryEndpoint = 'https://localhost:8080/query/';

Disable the SPARQL endpoint and redirect queries to the relational data backend

$smwgSparqlQueryEndpoint = false;
