title: Using DBpedia to find which Wikipedia categories are common to several given pages?
body: <p>I've forgotten all I once new about DBpedia and <code>SPARQL</code> and find all the examples too complex and hard to understand when I Google for them.</p>
  
  <p>What I wish to do is pass in two or three Wikipedia pages and get back the set of Wikipedia categories that all of the pages are members of.</p>
  
  <p>This seems that it should be utterly simple in <code>SPARQL</code> so I would appreciate a very minimal example to get me started.</p>
