Type Alias: Relationship

Relationship = "equivalent" | "source-is-narrower-than-target" | "source-is-broader-than-target" | "related-to" | "not-related-to"

The engine's normalized, version-neutral relationship between a source and a target concept - the FHIR R5 vocabulary, which the R4 equivalence tokens fold into cleanly. Surfaced on every match alongside the verbatim R4 token.

• equivalent ← R4 equivalent / equal
• source-is-narrower-than-target ← R4 wider / subsumes (the source is-a the target)
• source-is-broader-than-target ← R4 narrower / specializes (the target is-a the source)
• related-to ← R4 relatedto / inexact
• not-related-to ← R4 disjoint / unmatched
