Duplicate Concept | SAME_AS association reference set (foundation metadata concept) | Definition: The inactivation reason “Duplicate Concept” with association type “SAME_AS ”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.

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 may not always be straightforward. To reduce the impact on users/vendors, consider keeping the concept with the oldest effective date as this is likely to have had the most usage. Where the existing FSN for the older concept does not comply with current naming conventions, it may be possible to assign a newer and compliant FSN "in its place" i.e., without inactivating the concept. However, if the newer concept already carries the ideal, compliant FSN then it will not be possible to also assign that same FSN to the older concept, and so there may be no other option than to inactivate the older concept in favor of the newer, with its better FSN.
