MediaWikiSIOCRef MediaWiki SIOC Reference What is it about? By hosting Mediawiki 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 MediaWiki data to the SIOC ontology for the purpose of constructing SPARQL queries against MediaWiki articles and discussion comments.Why is it important? Treating Mediawiki 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: You can run the queries below or your own created ones using the Virtuoso SPARQL query page and you should use the following Graph(s) URI: Virtual Graph URI: http://host:port/mw_v. For example: Note: Default Graph URI value used in the queries below is: Physical Graph URI: not supported for now. What are the Linked Data Views supported?

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).<itemizedlist mark="bullet" spacing="compact"><listitem><ulink url="MediaWikiREFExample4">List of all registered <span style="color: red"> UNKNOWN tag:</span> members returned as an RDF Graph</ulink></listitem> </itemizedlist><bridgehead class="">Reference</bridgehead> <itemizedlist mark="bullet" spacing="compact"><listitem><ulink url="VirtRDFViewMediaWiki">MediaWiki Linked Data Views</ulink> </listitem> <listitem><ulink url="">MediaWiki Installation Guide</ulink></listitem> </itemizedlist><bridgehead class="">See also</bridgehead> <itemizedlist mark="bullet" spacing="compact"><listitem><ulink url="">ODS SIOC reference</ulink> </listitem> <listitem><ulink url="">Query ODS Data Spaces using SPARQL and Atom OWL Ontology</ulink> </listitem> <listitem><ulink url="">Query ODS Data Spaces using SPARQL and SKOS Ontology</ulink> </listitem> <listitem><ulink url="">Query ODS Data Spaces using SPARQL and FOAF Ontology</ulink> </listitem> <listitem><ulink url="">Query ODS Data Spaces using SPARQL and Annotea Ontology</ulink> </listitem> <listitem><ulink url="">ODS SPARQL Samples</ulink> </listitem> <listitem><ulink url="NorthWindREF">Northwind SPARQL Reference</ulink> </listitem> <listitem><ulink url="SIOCRefTutorial">Query Virtuoso Tutorials using SPARQL</ulink> </listitem> <listitem><ulink url="SIOCRefDocs">Query Virtuoso Documentation using SPARQL</ulink> </listitem> <listitem><ulink url="WordPressSIOCRef">WordPress SIOC Reference</ulink> </listitem> <listitem><ulink url="PHPBB3SIOCRef">phpBB SIOC Reference</ulink> </listitem> <listitem><ulink url="DrupalSIOCRef">Drupal SIOC Reference</ulink></listitem> </itemizedlist><para><ulink url="CategoryRDF">CategoryRDF</ulink> <ulink url="CategorySIOC">CategorySIOC</ulink> <ulink url="CategorySPARQL">CategorySPARQL</ulink> <ulink url="CategoryWiki">CategoryWiki</ulink></para> <para> </para> </ulink></section></docbook>
