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: http://demo.openlinksw.com/mediawiki/
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:
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.

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).
