Purpose

An

Concept

t	900000000000521006\|Association type reference set\|
ShowFormat	inline

represents a set of unordered associations of a particular type between

Gloss

PreSpace	false
t	components

.

...

Data structure

An

Gloss

SpacePreSpace	truefalse
t	Association reference set

is a

Gloss

Space	true
t	Component

PreSpace	false

Gloss

Space	true
t	reference set

used to represent associations between

Gloss

PreSpace	false
t	componentcomponents

. Its structure is shown in the following table.

...

Field

...

Data type

...

Purpose

...

Specref

RefType	(field)
t	id

...

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

RefType	(field)
t	active

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

...

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 .

...

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.

...

Specref

RefType	(field)
t	moduleId

...

Specref

RefType	(data type)
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

Space	true
t	subtype

of

Concept

t	900000000000443000\|Module (core metadata concept)\|

within the metadata

Gloss

t	hierarchy

.

Specref

RefType	(field)
t	refsetId

Specref

RefType	(data type)
t	SCTID

...

Identifies the

Gloss

Space	true
t	reference set

to which this

Gloss

Space	true
t	reference set member

belongs.

In this case, set to a

Gloss

Space	true
t	subtype

of

Concept

t	900000000000521006\|Association type reference set\|

. This indicates the nature of the association between the source and target

Gloss

t	components

.

...

Specref

RefType	(field)
t	referencedComponentId

...

Specref

RefType	(data type)
t	SCTID

t	component

of the association.

...

Specref

RefType	(field)
t	targetComponentId

...

Specref

RefType	(data type)

The identifier of the target

of the association.

Each member of a

Concept

t	900000000000522004\|Historical association\|
ShowFormat	inline

Gloss

Space	true
t	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\|
ShowFormat	inline

Gloss

Space	true
t	reference set

holds

Gloss

Space	true
t	Relationships

of a different nature between the

Gloss

t	components

. The

Concept

t	900000000000522004\|Historical association\|
ShowFormat	inline

Gloss

Space	true
t	reference set

contains associations:

from each
Gloss
Space true
t inactive description
to one or more other
Gloss
Space true
t Descriptions
that are current in the
Gloss
Space true
t release Version
in which the
Gloss
Space true
t description
was inactivated;
from each inactive
Gloss
Space true
t reference set
for which there is a current replacement to the replacement
Gloss
t reference set
;
from an
Gloss
Space true
t inactive description
to a
Gloss
Space true
t concept
that is current in the
Gloss
Space true
t Release Version
in which the
Gloss
Space true
t description
was inactivated, and which is correctly described by the Term of the
Gloss
t inactive description
;
From each
Gloss
Space true
t inactive concept
to one or more
Gloss
Space true
t concepts
that replace it.

The

Gloss

Space	true
t	component

identified by the

Specref

RefType	(field)
t	targetComponentId

must be an instance of the same class of

Gloss

Space	true
t	component

as the

Gloss

Space	true
t	component

identified by the referencedComponentIdfor all |Historical association|

Gloss

Space	true
t	reference sets

apart from the |REFERS TO

Gloss

Space	true
t	concept

association

Gloss

t	reference set

|.

Within the |REFERS TO

Gloss

Space	true
t	concept

association

Gloss

t	reference set

|, the referenced ComponentId field must be a

Gloss

Space	true
t	description

and the targetComponentIdmust be a

Gloss

t	concept

.

The

Specref

RefType	(field)
t	targetComponentId

is used differently in the |MOVED TO association

Gloss

t	reference set

|. In this case, the

Specref

RefType	(field)
t	targetComponentId

does not refer directly to a replacement

Gloss

t	component

, but rather to the namespace to which the

Gloss

Space	true
t	component

was moved to. The

Specref

RefType	(field)
t	targetComponentId

actually refers to the

Gloss

Space	true
t	concept

that represents the namespace. This approach is used since the organization sourcing the

Gloss

Space	true
t	component

may not always be able to determine the precise reference that is applicable in the receiving organization (namespace). Thus the responsibility for these references lies with the new responsible (receiving) organization.
