You can annotate your data requirements with several meta-information, such as information about its provenance, its task-dependency, a natural language description, and how the requirement shall be used. Below you can see an example that makes extensive use of the DQM-Vocabulary regarding the specification of data requirements.

&lt;pre&gt;
foo:PropertyCompletenessRule_1
      a       dqm:PropertyCompletenessRule ;
      dqm:testedClass foo:Class_Location ;
      dqm:testedProperty1 foo:Prop_Location_Country ;
      dqm:requiredProperty &quot;true&quot;^^xsd:boolean ;
      dqm:requiredValue &quot;true&quot;^^xsd:boolean ;
      dqm:reqName &quot;Country Completeness in Class Location&quot;^^xsd:string ;
      dqm:reqDescription &quot;Each instance of the class \&quot;Location\&quot; must have a property
                           value for the property \&quot;Country\&quot;&quot;^^xsd:string ;
