title: How to match exact string literals in SPARQL?
body: <p>I have this query. It matches anything which has "South" in its name. But I only want the one whose <code>foaf:name</code> is exactly "South".</p>
  
  <pre><code>SELECT Distinct ?TypeLabel 
  WHERE
  {
      ?a     foaf:name   "South" .
      ?a     rdf:type    ?Type .
      ?Type  rdfs:label  ?TypeLabel .
  }
  </code></pre>
