Artifacts Summary

Contents:

This page provides a list of the FHIR artifacts defined as part of this implementation guide.

Structures: Resource Profiles

These define constraints on FHIR resources for systems conforming to this implementation guide.

LOINC Change Set (CodeSystem)

Profile of CodeSystem to enable lossless representation of a LOINC change set aligned with Tinkar information model requirements. This profile is a specialization of the broader Terminology Change Set profile.
SNOMED Change Set (CodeSystem)

Profile of CodeSystem to enable lossless representation of a SNOMED change set aligned with Tinkar information model requirements. This profile is a specialization of the broader Terminology Change Set profile.
Terminology Change Set (CodeSystem)

Profile of CodeSystem to enable lossless representation of a terminology change set aligned with Tinkar information model requirements
Terminology Change Set Provenance (Provenance)

Profile of Provenance to use in concert with terminology change sets compliant with Tinkar information model requirements

Structures: Extension Definitions

These define constraints on FHIR data types for systems conforming to this implementation guide.

Defining Relationship Type

Indicator to distinguish between axioms explicitly stated vs. inferred by a reasoner or other logical processes
Description Acceptability

Boolean value to convey if a designation is case sensitive or not
Description Case Sensitivity

Coded value to identify what case sensitivity is reflected in description
Description Dialect

Subcategorization of language
EL Profile Set Operator

EL++ profile to describe the axiom as being part of the Necessary vs. Sufficient set for defining the concept
SNOMED Role Group

Where multiple property groupings are assigned for a particular concept, this identifies the group to which this property belongs. See also SNOMED concept 609096000 Role group (attribute)

Terminology: Value Sets

These define sets of codes used by systems conforming to this implementation guide.

Case Significance Value Set

Codes describing case significance for a terminology concept. The value set includes all codes from the SNOMED CT descending from 900000000000447004 Case significance.
Defining Relationship Type Value Set

Codes describing the nature of a relationship used to define a terminology concept. The value set includes all codes from the SNOMED CT descending from 900000000000006009 Defining relationship.
Description Acceptability Value Set

Codes describing acceptability of a given description for a terminology concept. The value set includes all codes from the SNOMED CT descending from 900000000000511003 Acceptability.
Dialect Value Set

Codes representing the specific dialect used in a description for a concept. The value set includes all codes from the SNOMED CT descending from 900000000000506000 Language type reference set.
EL Profile Set Operator Value Set

Codes describing the nature of an axiom in relationship to a concept, in terms of if it is part of the Necessary vs. Sufficient set for defining the concept. The value set includes all codes from the SNOMED CT descending from 900000000000444006 Definition status.
