title: select all triples, indicating named graph if relevant
body: <p>Let's say I make the following insertions into my GraphDB 8.3 triplestore:</p>
  
  <pre><code>PREFIX : &lt;http://example.com/&gt;
  insert data { :hello a :word }
  </code></pre>
  
  <p>and</p>
  
  <pre><code>PREFIX : &lt;http://example.com/&gt;
  insert data { graph :farewells { :goodbye a :word }}
  </code></pre>
  
  <p>now, if I ask </p>
  
  <pre><code>select * where {
      graph ?g {
          ?s ?p ?o .
      } 
  }
  </code></pre>
  
  <p>I only get </p>
  
  <pre><code>+--------------------------------+------------------------------+---------------------------------------------------+---------------------------+
  |               ?g               |              ?s              |                        ?p                         |            ?o             |
  +--------------------------------+------------------------------+---------------------------------------------------+---------------------------+

  <p>I can obviously get both "triples about words" with the following, but then the named-graph membership is not shown</p>
  
  <pre><code>select * { ?s ?p ?o }
  </code></pre>
  
  <p>How can I write a query that retrieves both triples about words and indicates that <code>{ :goodbye a :word }</code> comes from graph <code>:farewells</code> ?</p>
