Purpose

An

Concept

represents a set of unordered associations of a particular type between

Gloss

t	components

.

Data structure

An

Gloss

Space	true
t	Association reference set

is a

Gloss

Space	true
t	reference set

used to represent associations between

Gloss

t	components

. Its structure is shown in the following table.

Field

Purpose

Specref

RefType	(data type)
t	UUID

A 128 bit unsigned

Specref

RefType	(data type)
t	Integer

, uniquely identifying this

Gloss

t	reference set member

.

Different versions of a reference set member share the same

Specref

RefType	(field)
t	id

but have different

Specref

RefType	(field)
t	effectiveTime

. This allows a reference set member to be modified or made

Specref

(i.e. removed from the active set) at a specified time.

NO

YES (Full/Snapshot)

Specref

RefType	(field)
t	effectiveTime

Specref

RefType	(data type)
t	Time

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

Gloss

Space	true
t	reference set member

became the current version.

The current version of this

Gloss

Space	true
t	reference set member

at time T is the version with the most recent

Specref

RefType	(field)
t	effectiveTime

prior to or equal to time T .

YES

YES (Full)

Optional (Snapshot)

Specref

RefType	(field)
t	active

Specref

RefType	(data type)
t	Boolean

The state of the identified

Gloss

Space	true
t	reference set member

as at the specified

Specref

RefType	(field)
t	effectiveTime

.

If

Specref

RefType	(field)
t	active

= 1 (true) the

Gloss

Space	true
t	reference set member

is part of the current version of the set, if

Specref

RefType	(field)
t	active

= 0 (false) the

Gloss

Space	true
t	reference set member

is not part of the current version of the set.

YES

NO

Specref

RefType	(field)
t	moduleId

Specref

t	SCTID

Identifies the

Gloss

Space	true
t	SNOMED CT module

that contains this

Gloss

Space	true
t	reference set member

as at the specified

Specref

RefType	(field)
t	effectiveTime

.

The value must be a

Gloss

.

YES

NO

Specref

RefType	(field)
t	refsetId

Specref

RefType	(data type)
t	SCTID

Identifies the

belongs.

In this case, set to as subtype descendant of: ??

NO

Specref

RefType	(field)
t	referencedComponentId

Specref

RefType	(data type)
t	SCTID

A reference to the

.

NO

Specref

RefType	(field)
t	targetComponentId

Specref

Historical Association Rules and Guidance

Each member of a

Concept

t	900000000000522004\|Historical association\|
ShowFormat	inline

reference set represents a reference from an

Gloss

Space	true
t	inactive component

to other equivalent or related

Gloss

Space	true
t	components

that were current in the

Gloss

Space	true
t	Release Version

in which that

Gloss

Space	true
t	component

was inactivated.

Each

Concept

t	900000000000522004\|Historical association\|

reference set represents a different type of association between the

Gloss

t	components

referred to by the

Specref

t	referencedComponentId

and the

Specref

as shown in .
