Purpose

A

Concept

t	446609009\|Simple type reference set\|
ShowFormat	inline

allows a set of

Gloss

Space	true
t	components

to be specified for inclusion or exclusion for a specified purpose. This type of

Gloss

Space	true
t	reference ret

represents an extensional definition of a subset of SNOMED CT

Gloss

t	components

. Thus it can be used to fully enumerate a subset of

Gloss

t	concepts

,

Gloss

Space	true
t	descriptions

or

Gloss

t	relationships

.

Reference Set Data Structure

A Simple

does not have any addition additional fields.

.

Different versions of a reference set member share the same

but have different

t	Time

The inclusive date or time at which this version of the identified

became the current version.

The current version of this

prior to or equal to time T .

YES

YES (Full)

is part of the current version of the set, if

Specref
