title: How to Query Individuals using OWL DL Query in Protege 4?
body: <p>How do I query individulas in my ontology, here is a description of what I would like to do (similar to SQL queries):</p>
  
  <p>I have three classes (components, features, and polarity). The polarity value can be positive_polarity or negative_polarity, both are subclasses of polarity.</p>
  
  <ul>
  <li>a_component hasFeature a_Feature</li>
  <li>a_Feautre hasPolarity a_Polarity</li>
  </ul>
  
  <p>I would like to list all components which have a positive_polarity value.</p>
  
  <p>How can this be achieved using the DL Query tab in protege 4?</p>
