DC Indexing area: same for Simple and Qualified DC


Simple DC contains two "indexing" elements: subject and coverage.

  • In Qualified DC, coverage is refined by two qualifiers: temporal and spatial.

Instead of trying to implement Simple and Qualified separately, use the standard Qubit access points interface with DC labels.

  • Means using DC Qualified even in DC Simple template.


  • DC subject element.
  • Handle by Qubit term via related records in object_term_relation table.


  • No strict DC equivalent (but can be mapped to DC subject).
  • Handle by Qubit actor::authorized_form_of_name via related records in event table.

Coverage - spatial

  • DC spatial qualifier (refines DC coverage element).
  • Handle by Qubit place via related records in object_term_relation table.

Coverage - temporal

  • DC temporal qualifier (refines DC coverage element).
  • Handle by Qubit historical_event via related records in object)_term_relation table.
