Mediawiki with Fuseki triplestore backen

In this page I will go over the steps required to setup Semantic Mediawiki with a Triple Storage graph database, with Apache Jena Fuseki, [1] SPARQL server.

According to SMW documentation:[2]

By default, Semantic MediaWiki (SMW) stores all data in the same relational database (usually, a MySQL database) that is used by MediaWiki. This ensures a simple setup, but a relational database is not an ideal type of storage for semantic data. A more natural data model for SMW data is RDF, a data format that organizes information in graphs rather than in fixed database tables.

Running Fuseki

Fuseki SPARQL server


SMW Setting for Fuseki

With SMW installed and enabled

enableSemantics( 'localhost' );

The following settings are added to LocalSettings.php

$smwgDefaultStore = 'SMWSparqlStore';
$smwgSparqlRepositoryConnector = 'fuseki';

$smwgSparqlEndpoint["query"] = 'http://localhost:3030/triplewiki/query';
$smwgSparqlEndpoint["update"] = 'http://localhost:3030/triplewiki/update';
$smwgSparqlEndpoint["data"] = '';

Test queries
