title: how to make use of rdf data of dmoz with mysql and php?
body: <p>I have searched through the web, but still not be able to get a solid answer.
  My goal is to make use of <a href="http://www.dmoz.org/rdf.html" rel="nofollow">rdf data</a> from dmoz, so here are 2 questions:</p>
  
  <ol>
  <li><p>how to import the rdf into mysql? (any solid tool could be used?)</p></li>
  <li><p>how to make the data queryable through SPARQL? (what component or query engine I should use)</p></li>
  </ol>
  
  <p>from what I have learned I need to build the storage based on <a href="http://librdf.org/" rel="nofollow">Redland RDF libraries</a>, and then I can query it with SPARQL. But further reading into redland, they don't have a good document of php. Those missing gap make me confused as I am pretty new to the rdf technology.</p>
