| Inactivation Reason | Association | Definition |
|---|
Duplicate | SAME_AS | This combination of inactivation reason and association type explicitly states that the inactivated concept (A) semantically represents exactly the meaning of the remaining active concept (B). Implicitly it also means that (A) SAME_AS (B) always, by definition implies (B) SAME_AS (A). The definition includes the requirement to ensure any analysis expressed in terms of (A) returns the same subtypes as would have been present had the concept (B) been substituted into the query logic, and vice versa. Please note that the meaning of the concept is based on the FSN. |
| Guidance |
|---|
- Inactivate non-synonymous synonyms
If any of the concept’s synonyms are considered to be non-synonymous, these should first be inactivated and re-assigned to either the concept that matches the meaning or if not available a new concept created. - Specify target concept
The target component identifies the active concept that this concept duplicates.
Note: Where possible consider keeping the concept with the oldest effective date as this is likely to have had the most usage The choice of which concept should be inactivated should be based on keeping the concept that has the most compliant and specific Fully Specified Name. - Annotation
Provide evidence/reference to support the concepts are duplicates - Additional notes:
- The requirement to ensure any analysis expressed in terms of (A) returns the same result as it would if the same logic was applied to (B) is contingent on both concepts being modeled correctly.The choice of which concept should be inactivated should be based on keeping the concept that has the most compliant FSN, complete and correct modeling, and/or synonyms.

Resolving sequences of Historical Associations
The intention is that
...
functionality to resolve sequences of Historical Associations will normally be seamlessly integrated into the tooling so as to present to the user the appropriate updated historically association to be allocated.
Whenever an already stated “SAME_AS” target itself also becomes inactive - whether at the same release or later, identifying the replacement for the original concept, should follow the combinatorial logic stated below.
