Glossary Definition

UNDER RF1: The state of a component that is thought to belong in a different Namespace but which is maintained with its current SCTID while awaiting addition to the new Namespace.

UNDER RF2: The state of a component that is thought to belong in a different Module in a different Extension or Edition, while awaiting transfer to that new Module.

A new Concept and associated Descriptions may be added with this Status where a missing SNOMED CT Concept is urgently required to support the needs of a particular Extension or Edition. Existing Concepts are also given this status when it is recognized that they should be moved to a different Extension or Edition or to the International Release.

Terminology Services Guide

UNDER RF1: The Concept is still active but it is in the process of being moved to another namespace and when the move is complete it will be marked as inactive.

UNDER RF2: The Concept is active but in the process of being moved to another Module and Extension or Edition. When the move is complete it will be remain active and with the same identifier.

Editorial Guide

N/A

• This used? And does this mean that the |concept inactivation indicator attribute value reference set| contains references to active components which are pending move?
• JR: Yes, it is used extensively. And yes, the concept inactivation indicator refset does contain a lot of componentIds that are in fact active. So the name of the refset is indeed already seriously misleading. Gets worse if codes assigned to status=MOVED ELSEWHERE are also permitted to stay indefinitely active after the move is completed.

Glossary Definition

RF1: The state of a component that has been moved to another Namespace.

The state of a component that has been moved to another Module and in a different Extension or Edition.

Concepts or Descriptions may be moved from an Extension or Edition to the International Release, from the International Release to an Extension or Edition, or between one Extension or Edition and another. Moves occur if responsibility for supporting the Concepts changes to another organization; this change of responsibilty is recorded solely by means of a change in Module.

Terminology Services Guide

The Concept has been made inactive because it has been moved to another namespace.

The concept may or may not become inactive in its original module: it may be best practice for it to do so, particularly in the special case where it moves down the dependency tree, but (unlike RF1) this is not strictly technically required.

Under RF2, correct use of the "component moved elsewhere" status is a matter for urgent clarification, especially if in fact most components with that status should now remain active in their original source module.

Editorial Guide

• Applies to a component that has been moved to, or is pending a move to another namespace
• The target component identifies the target namespace, not the new component
  Not any more! Another topic for urgent clarificaiton is how the MOVED_TO attribute should now be used to record where a moved component went, if the identifier remains unchanged after the move.
  
• BAC: this is good to hear, because when something moved to a namespace, there isn't anything in the data to tell you what namespace that actually is. You need to figure out how to find the namespace registry document.

EXAMPLE(S):

332570000 |Dermablend cover cream 28.4g (product)|
442596000 |Left 30 degree caudal-right rostral oblique projection (qualifier value)|

• BAC: What is an implementer to do when a concept has moved from the International release to an Extension/Edition that is for a different country where that user does not have a license?

Terminology Services Guide

The Concept is of limited value as it contains classification categories such as 'Not Elsewhere Classified' which do not have a stable meaning within SNOMED CT . Until 2010 concepts with this status were regarded as active but since then they have been marked as inactive.

Editorial Guide

No longer in use and no requirement to retainuse and no requirement to retain

EXAMPLE(S):

218584008 |Adverse reaction to blood or blood products NOS (disorder)|
330494006 |Prednisolone eye drops (product)|

Why is limited component still an active concept in the International Edition?

JR: Because there are, and will remain, tens of thousands of inactive codes that will be forever held in that status.

The Concept has been made inactive because it contains an error.

Editorial Guide

• The concept has been made inactive because it contains an error
• The target component identifies the active component that replaces this component
  But exactly what 'replace' means here is crucial to define more precisely if automated data healing is to be possible

Examples are required to illustrate what en error in a concept can be. For descriptions, this value is used for technical errors. However, what does error mean here - modeling error?, and if so, how could this be distinguished from |Nonconformance to editorial policy component|... So, when the modelling does conform to editorial policies, but the semantics represented by its definition is simply incorrect. (?)

JR: Was always rather vaguely defined IMHO, and so that probably explains why there are not many assigned to this status (n=about 4200)

The current collection of Erroneous Codes includes many that arguably should always have properly been Limited Status:

165483004 Red blood cell shape NOS (observable entity)

199546002 Fetus with damage due to other maternal disease NOS (disorder)

212157007 Complete cervical cord injury, without bony injury, C1-4 (disorder)

...or ambiguous:

106959003 Family cricetidae AND/OR other rat (organism)

...plus some where you have to wonder what the 'error' was:

202620006 Osteophyte (disorder)

The Concept has been made inactive because it is inherently ambiguous either because of an incomplete fully specified name or because it has several associated terms that are not regarded as synonymous or partial synonymous.

• The concept has been made inactive because it is inherently ambiguous. This may be because of an incomplete fully specified name or because it has several associated terms that are not regarded as synonymous or partially synonymous

JR: Historically very unloved as a status (n=2085)

Mostly given over to codes for microorganism species or genus that are no longer belived to exist, plus a handful of codes for sexual orientations that were in Olden Times classified and semantically tagged as a disorder.

Also used in UK for pharmaceutical AMPs that were never actually available on the market.
