Inactive concepts

Inactive concepts are no longer active in the terminology. When the first release format (RF1) was used, inactivated content was moved into this hierarchy. However, this approach is no longer used in the current release format (RF2).

Navigational concepts

The concepts in navigational hierarchies are used for structured data entry and support the location of concepts in hierarchies. They can order data by priority or another convention (e.g. cranial nerve order or topics related to diabetes). Navigational concepts exist only to support navigation.
