A new row representing an inactivated version of each active relationship, in which the concept participates, is added to the Stated Relationship file.

Inactivating a concept's active relationships involves adding a new row to the Stated Relationship file, with the active attribute set to '0' and the effective time set to a more recent time, for each relationship in which the inactive concept appears as the source, destination or type. For more information please refer to 5.4.4.3 Inactivate Relationship in an Extension.

A new row representing an inactivated version of the concept is added to the Concept file.

The attributes of the new version of the concept are set as follows:

  • id is set to the conceptId of the concept being inactivated
  • effectiveTime is set to the date the extension will be published
  • active is set to '0' to indicate that the concept will become inactive at the time of publication
  • moduleId is set to identify a module in the extension
  • definitionStatusId is set to

Stated Relationship

Axiom

Inactivating a concept's active relationships involves adding a new row to the OWL axiom reference set file, which inactivates the member of the reference set representing the stated axiom of the concept being inactivated.

For more information please refer to 5.4.6.3 Remove Members from a Reference Set. 

The attributes of the new version of the concept are set as follows:

  • id is set to the UUID of the reference set member referencing the concept being inactivated
  • effectiveTime is set to the date the extension will be published
  • active is set to '0' to indicate that the reference set member will become inactive at the time of publication
  • moduleId is set to identify a module in the extension
  • referencedComponentId is set to the concept identifier of the concept being inactivated

Inferred Relationships File

An inactive concept does not participate in any active relationships. This means that when inactivating a concept, all active relationships, in which the concept was used as the source, destination or type, must be inactivated. As a result, the inactive concept is removed from the subtype hierarchy, and will no longer have any defining relationships. This reinforces the point that an inactive concept should not be used in any new data entry, as it will not be subsumed by any other concept.
