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. | |||||||||||||||
