#MediaWiki
---++ <nowiki>MediaWiki</nowiki> SIOC Reference

---+++What is it about?
By hosting <nowiki>Mediawiki</nowiki> in Virtuoso, you gain integration of your data, both in its existing wiki form, with the ability to manage Talk Pages as NNTP groups, or map the <nowiki>MediaWiki</nowiki> data to the SIOC ontology for the purpose of constructing [[SPARQL]] queries against <nowiki>MediaWiki</nowiki> articles and discussion comments.

---+++Why is it important?
Treating <nowiki>Mediawiki</nowiki> as a repository of semantically marked-up data allows constructing [[SPARQL]] Queries thereby offering a powerful search feature through mapping the data to the SIOC ontology.

---+++How can one use this feature?
   * You can find a working demonstration at the following location: http://demo.openlinksw.com/mediawiki/
   * You can run the queries below or your own created ones using the [[http://demo.openlinksw.com/sparql][Virtuoso SPARQL query page]] and you should use the following Graph(s) URI:
      1. Virtual Graph URI: http://host:port/mw_v. 
         * For example: http://demo.openlinksw.com/mw_v
            * Note: Default Graph URI value used in the queries below is: http://demo.openlinksw.com/mw_v
      2. Physical Graph URI: not supported for now.

---+++What are the Linked Data Views supported?
   * <a href="%ATTACHURLPATH%/MediaWiki_rdf_views_script.sql" style="wikiautogen"><nowiki>MediaWiki_rdf_views_script.sql</nowiki></a> or view the online version [[VirtRDFViewMediaWiki][here]].

---+++Using SPARQL CONSTRUCT to Export SIOC-based RDF Data Sets
CONSTRUCT-based SPARQL queries are very useful when trying to expose RDF (via a SPARQL Endpoint) to RDF Data Set consumers that do not support SPARQL. In a sense, the SPARQL CONSTRUCT statements as part of a SPARQL Protocol payload deliver a Data Web (Web 3.0) Experience to Interactive-Web Clients (Web 1.0).
