$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
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 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;
