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
querying
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
In Fuseki interface
