title: Meaning of OWL axiom in Turtle syntax?
body: <p>I have the turtle statement:</p>
  
  <pre><code>:Parent rdf:type owl:Class ;
  
      owl:equivalentClass ;
          rdf:type owl:Class ;
          owl: unionOf (
                  [   rdf:type owl:Restriction ;
                      owl:onProperty :fatherOf ;
                      owl:someValuesFrom :Person
                  ]
                  [   rdf:type owl:Restriction ;
                      owl:onProperty :motherOf ;
                      owl:someValuesFrom :Person
                  ]
          }
      ].
  </code></pre>
  
  <p>Could someone explain to me the concept of Parent within this statement. Would it also be possible for someone to be a mother or father of a person without being a parent?</p>
