title: How to query dbpedia.org with sparql
body: <p>I'm very new in OpenData and try to write a query in SPARQL.</p>
  
  <p>My goal is to get data for following set of criteria:
   - Category: Home_automation
   - select all items from type "Thing"
   - with at least one entry in "is Product of"
   - that have a picture-url with a German description</p>
  
  <p>I tried the following:</p>
  
  <pre><code>PREFIX cat:  &lt;http://dbpedia.org/resource/Category:&gt;
  PREFIX skos: &lt;http://www.w3.org/2004/02/skos/core#&gt;
  
  SELECT *
  WHERE {
    cat:Home_automation skos:broader ?x
  }
  </code></pre>
  
  <p>But now I don't know how to add the other filters to the where clause.
  I tried to user broader:... to get the items, but I think that was the wrong direction.</p>
  
  <p>I tested the queries with: <code>https://dbpedia.org/sparql</code></p>
  
  <p>The result should be: </p>
  
  <pre><code>|         (label)          | (url) 
  |--------------------------|-----------------------------------
  |"Kurzzeitwecker"@de       | urls to the picture of the device 
  |"Staubsauger"@de          | -||-
  |"Waschmaschine"@de        | -||-
  |"Geschirrspülmaschine"@de | -||-
  </code></pre>
  
  <p>Does anyone have some tips please?</p>
  
  <p>UPDATE: new query:</p>
  
  <pre><code>PREFIX cat: &lt;http://dbpedia.org/resource/Category:&gt;
  PREFIX rdf: &lt;http://www.w3.org/1999/02/22-rdf-syntax-ns#&gt;
  PREFIX owl: &lt;http://www.w3.org/2002/07/owl#&gt;
  PREFIX rdfs: &lt;http://www.w3.org/2000/01/rdf-schema#&gt;
  
  SELECT ?s ?label WHERE {
    ?s ?p cat:Home_automation .
    ?s rdf:type owl:Thing .
    ?s rdfs:label ?label
    FILTER (LANG(?label)='de')
  }
  order by ?p
  </code></pre>
