Semantic reuse refers to the use of an RDF export by an external application. A number of Semantic Web tools for processing RDF exports are available today. This page lists various tools that have been tested with SMW and explains what features they offer.

  • The Geocoding Tools for Python provide a simple toolkit for obtaining the geographic coordinates of places in the real world. For example, you can find out the location of a city you are in by providing the city name. The name is looked up in various sources, including Semantic MediaWikis, and the location is returned.
  • Tabulator is an online browser for RDF documents available at <http://www.w3.org/2005/10/ajaw/tab.html>. Using it on external resources such as CreationWiki requires a change in security settings of the browser to enable JavaScript. After this is done, RDF of CreationWiki can be loaded conveniently by loading the URL of some RDF export, e.g. <http://creationwiki.org/Special:ExportRDF/Global_flood>. The interface is still somewhat crude, but the tool shows that dynamic interfaces for browsing RDF and RDF-enabled sites are feasible. Tabulator takes advantage of Semantic MediaWiki's feature of creating browsable RDF which includes "backlinks" in RDF triples as well. (See Help:Semantic RDF export for full particulars on the content of a CreationWiki RDF export feed.)
  • Longwell is a Java-based facetted browser for RDF. It includes features for browsing, querying and query refinement, Timeline support and graphical presentation of RDF graphs. It works very well with the RDF generated by Semantic MediaWiki and its facetted browsing capabilities provide some real added value for the semantic data. It is available online via <http://simile.mit.edu/longwell/>.
  • FOAF Explorer is an online viewer for RDF files that use the Friend Of A Friend vocabulary. It can be accessed via <http://xml.mfd-consult.dk/foaf/explorer/>. Like most FOAF tools, FOAF Explorer is still somewhat limited and does not deal well with arbitrary RDF that just contains some FOAF statements. CreationWiki's administration has not tested this product on any of its annotated articles.
  • Piggy Bank is a browser extension for Firefox available at <http://simile.mit.edu/piggy-bank/>. Semantic MediaWiki refers to a page's RDF specification within its HTML header so that Piggy Bank can find it. In effect, Piggy Bank will collect RDF of all visited articles during browsing. Of course, the further use of this RDF, as in all applications of Piggy Bank, is left to the user.
  • KAON2 is a reasoner and ontology management API for OWL DL and SWRL. It can be used to check the validity of the exported OWL specifications. In conjunction with the OWL tools, you can also transform the exported RDF into LaTeX sources that show the according DL statements (which tend to be more readable for humans, or at least for DL-aware humans).
  • OpenLink RDF Browser is a Browser independent and Javascript based RDF Browser that is part of the OpenLink Ajax Toolkit (OAT). The deliverables includes a live demonstration that works with Semantic MediaWiki RDF Export pages.
