SPARQL endpoint

Installation

Semantic MediaWiki supports external Semantic Web applications via its RDF export.

We provide a dedicated SPARQL endpoint as a further service to access the knowledge within wiki.ontoworld.org. Currently, we hava a Java-based server running on Danny Ayers' machine.

The server does four things:

  • occasionally crawls the full index (using the HTML pages)
  • every 4 seconds crawls the RecentChanges page
  • every n seconds re-crawls all new pages from index or recent changes
  • continuously serves all crawled data via Joseki. This endpoint can be found at http://sparql.semwiki.org (Redirect).

Note: The endpoint is currently broken
