title: SPARQL query for Dublin Core
body: <p>I'm new in the field of ontology. I'm using the Dublin Core as an additional ontology to the ontology that I'm creating which is a curriculum ontology. But, I'm having trouble on how I can retrieve certain information. </p>
  
  <p>For example, I have a class named, <code>Bibliographic Resource</code>, this is a class in the Dublin Core ontology. In this class, I have a member named <code>Introduction_to_Computer_Science_1</code> and in this member, I have a data property named, <code>Alternative Title</code> with a string value named <code>ICS Book</code>. I want to retrieve the Alternative title of the member which is the <code>ICS Book</code>.  I'm using SPARQL as my query language and Protégé as my ontology tool. This is my query</p>
  
  <pre><code>SELECT ?title 
      WHERE{
           &lt;http://semanticweb.org/LearningPlanOntology#Introduction_to_Computer_Science_1&gt; dc:'Alternative Title' ?title.
      }
  </code></pre>
  
  <p>Can anyone tell me what's wrong with my query?</p>
