Concept map

Fully specified name: Concept map (concept)

A representation of relationships between concepts in specified systems and contexts.

Scope note
Direction, relationship type, and source and target versions matter.
Synonyms
None recorded as true synonyms in this context.
Monograph
FHIR terminology resources (draft)
External mappings
None recorded. In W0 no mapping to SNOMED CT® or any external authority is asserted for this entry. A future mapping record will carry source system, identifier, version, relation type, evidence, author, confidence where meaningful, and review state.
Formal status
Editorial entry only. It is not part of any released ontology and a prose edit here changes no formal definition.

Draft. This entry is an unreviewed draft. Its sources have not been checked by a named person and no domain reviewer has approved it. Treat every claim as provisional.

Notes

A concept map records how concepts in one system relate to concepts in another: this local code corresponds to that SNOMED CT concept; this legacy procedure code is broader than that current one. In FHIR (Fast Healthcare Interoperability Resources) the ConceptMap resource holds such mappings as groups of elements, each stating a source code, a target code, and a relationship from a fixed list (related to, equivalent, source is narrower than target, source is broader than target, not related to), with optional comments and dependencies on other codes.

The scope note lists what makes a mapping usable rather than merely present. A mapping has a direction: that A maps to B does not by itself say that B maps to A. It has a relationship type, and "equivalent" is a strong claim that most mappings cannot honestly make. It applies between stated versions of the source and target systems, and may become wrong when either is updated. And it has an author and a basis, which is why NucLex's reserved mapping schema includes evidence, author, confidence, and review state.

In this publication's language the word concept map is used in this terminology sense only, not in the educational sense of a hand-drawn diagram of ideas. NucLex entries carry no mappings in W0; the entry on Identifier explains why. The FHIR R5 ConceptMap page is the authoritative reference.
