Variable: FATAL_CODES
constFATAL_CODES:object
Stable fatal codes - thrown (as a TerminologyError) when input cannot be loaded into
a usable model at all. Always thrown, never swallowed. key === value, part of the contract.
Type Declaration
TERM_CODESYSTEM_MALFORMED
readonlyTERM_CODESYSTEM_MALFORMED:"TERM_CODESYSTEM_MALFORMED"="TERM_CODESYSTEM_MALFORMED"
A CodeSystem source was structurally unusable - a FHIR resource with the wrong resourceType,
or a delimited source whose configured code/display column is absent from the header. Thrown
rather than silently loading an empty or mis-keyed release. (Malformed individual rows are
skipped-and-surfaced load warnings, not fatals - only an unusable source is fatal.)
TERM_CONCEPTMAP_MALFORMED
readonlyTERM_CONCEPTMAP_MALFORMED:"TERM_CONCEPTMAP_MALFORMED"="TERM_CONCEPTMAP_MALFORMED"
A ConceptMap resource was structurally unusable - wrong resourceType, or a group/element
missing a required field. Thrown rather than silently loading a partial, misleading map.
TERM_CROSSWALK_MALFORMED
readonlyTERM_CROSSWALK_MALFORMED:"TERM_CROSSWALK_MALFORMED"="TERM_CROSSWALK_MALFORMED"
A crosswalk map source was structurally unusable - e.g. a SNOMED complex-map RF2 refset with empty content or a header missing a required column. Thrown rather than silently loading an empty or mis-keyed map. (Malformed individual rows are skipped-and-surfaced warnings, not fatals.)
TERM_MAP_NOT_INVERTIBLE
readonlyTERM_MAP_NOT_INVERTIBLE:"TERM_MAP_NOT_INVERTIBLE"="TERM_MAP_NOT_INVERTIBLE"
An inversion of a directional crosswalk was requested - a forbidden operation. The GEMs and the SNOMED→ICD-10-CM map are authoritative in one direction only; a forward map is not the inverse of the backward map. Thrown by ../crosswalk/gems.invertGem so the never-invert refusal is a first-class, discoverable contract rather than a silent absence.
TERM_VALUESET_MALFORMED
readonlyTERM_VALUESET_MALFORMED:"TERM_VALUESET_MALFORMED"="TERM_VALUESET_MALFORMED"
A ValueSet resource was structurally unusable - wrong resourceType, or a compose/expansion
whose required shape (an include that is not an object, a contains entry missing its code)
is corrupt. Thrown rather than silently loading a partial value set that would bind some codes
and quietly drop others. (A filter operator the engine does not implement is not fatal - it
is the surfaced TERM_VALUESET_CANNOT_EXPAND diagnostic at expansion time.)
Example
import { FATAL_CODES } from "@cosyte/terminology";
FATAL_CODES.TERM_CONCEPTMAP_MALFORMED; // => "TERM_CONCEPTMAP_MALFORMED"
