Coding

Note

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

Computational Definition

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

Information Model

Some Coding attributes are inherited from Element.

Field	Flags	Type	Limits	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.
name		string	0..1	The human-readable name for the coded concept, as defined by the code system.
system		string	1..1	The terminology/code system that defined the code. May be reported as a free-text name (e.g. ‘Sequence Ontology’), but it is preferable to provide a uri/url for the system.
systemVersion		string	0..1	Version of the terminology or code system that provided the code.
code		code	1..1	A symbol uniquely identifying the concept, as in a syntax defined by the code system. e.g. ‘civic.did:30’, ‘MONDO:005061’, and ‘C3512’ are codes defined by different systems for representing the concept of ‘lung adenocarcinoma’. If a dereferencable identifier is available for the code, it should be provided in the iris field.
iris	⋮	iriReference	0..m	A list of IRIs that are associated with the coding. This can be used to provide additional context or to link to additional information about the concept.
