Concept Mapping

Note

This data class is at a trial use maturity level and may change in future releases. Maturity levels are described in the maturity-model.

Computational Definition

A mapping to a concept in a terminology or code system.

Information Model

Some ConceptMapping attributes are inherited from Element.

Field

Description

id

string

0..1

The ‘logical’ identifier of the data element in the system of record, e.g. a UUID. This ‘id’ is unique within a given system, but may or may not be globally unique outside the system. It is used within a system to reference an object from another.

extensions

 ⋮

Extension

0..m

A list of extensions to the Entity, that allow for capture of information not directly supported by elements defined in the model.

coding

Coding

1..1

A structured representation of a code for a defined concept in a terminology or code system.

relation

string

1..1

A mapping relation between concepts as defined by the Simple Knowledge Organization System (SKOS).

IMPLEMENTATION GUIDANCE

  1. Populating the relation attribute

  • A mapping relation must be provided in any ConceptMapping.

  • Permissible values come from the ‘mapping relation’ branch of the Simple Knowledge Organization System (SKOS), which includes 5 possible mapping relations:

    • relatedMatch

    • closeMatch

    • exactMatch

    • broaderMatch

    • narrowerMatch

  • Refer to documentation/definitions here for help choosing the term that best fits.

  • Use the root ‘mappingRelation’ term if unsure which to choose, or you do not care to discriminate between more specific relations.
