DC Related Resources area: same for Simple and Qualified
Future iteration: handle DC elements via Qubit relations


Simple DC distinguishes the source element (resource from which present resource is derived) and the more general relation element.

  • Qualified DC adds 13 qualifiers that refine the relation element.
  • Currently, these can only be implemented in Qubit as text fields, no difference in implementation in Simple or Qualified DC templates.
  • Exception: Qualified DC relation (partOf) is required by Qubit to manage hierarchical levels of description (information_object::parent_id).

In a future iteration, all relations (to source or other objects) should be managed by Qubit relation table.

Level of description

  • Qubit-required field (information_object::level_of_description) allowing user to characterize different types and levels of "parts".
  • Ship with a default "DC Levels of Description" taxonomy that administrators can customize.

Is part of

  • Qubit-required field (information_object::parent_id) that links current description to parent object.

Other relations

  • DC relation element.
  • Maps to Qubit information_object::related_units_of_description.
  • Requires user to manually enter proper DC qualifiers.


  • DC source element.
  • Does not map to any core Qubit field.
  • Handle via Qubit property::name="source" value=" "
