Non-Conformance to Editorial Policy

ALTERNATIVE association reference set (foundation metadata concept)
Additional notes:
Examples:
Semantic meaning the same but FSN different:
235998001 Perinephric abscess (disorder) - inactivated
SAME_AS
80640009 Perirenal abscess (disorder)
Both concepts had an effective date of 2002-01-31 and so the decision was based on current clinical usage and the retained concept already had a synonym of Perinephric abscess.
Identical FSN but different semantic tag:
145857006 Soft tissue X-ray abnormal (situation) - inactivated
SAME_AS
168711005 Soft tissue X-ray abnormal (finding)

Non-Conformance to Editorial Policy | REPLACED_BY ALTERNATIVE No suitable replacement identified | The inactivation reason “Non-conformance to Editorial Policy” explicitly states that the inactivated concept does not comply with a specific Editorial Guideline valid at the point of inactivation. From time to time editorial policy may change, either to revise what is considered to be within scope for the International Edition of SNOMED CT, or to support changes in modeling practice and thereby bring greater consistency to existing content. In the latter scenario, the necessary refactoring or remodeling of content can change the meaning of existing SNOMED CT concept FSN’s or the implied meaning of their logical definitions. |

Non-Conformance to Editorial Policy: Update of FSN to comply with Editorial Guidance: The use of "and" which has the implied meaning of "and/or" Editorial guidance on conjunction and disjunction states that the use of "and" in structural groupers has an implied meaning of "and/or" and therefore the FSN is to be updated to make the inclusive disjunction implicit with the use of "and/or". While this technically represents a change in meaning, as this is both a structural grouper and with the agreement of the community of practice, change of the FSN alone is supported.

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 “REPLACED_BY” 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.
