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.

...

Data type

...

Purpose

...

id (field)

...

UUID (data type)

...

A 128 bit unsigned Integer (data type), uniquely identifying this

Gloss

t	reference set member

.

Different versions of a reference set member share the same id (field) but have different effectiveTime (field). This allows a reference set member to be modified or made active (field) (i.e. removed from the active set) at a specified time.

...

effectiveTime (field)

...

Time (data type)

...

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 effectiveTime (field) prior to or equal to time T .

...

active (field)

...

Boolean (data type)

...

The state of the identified

Gloss

Space	true
t	reference set member

as at the specified effectiveTime (field) .

If active (field) = 1 (true) the

Gloss

Space	true
t	reference set member

is part of the current version of the set, if active (field) = 0 (false) the

Gloss

Space	true
t	reference set member

is not part of the current version of the set.

...

moduleId (field)

...

SCTID (data type)

...

Identifies the

Gloss

Space	true
t	SNOMED CT module

that contains this

Gloss

Space	true
t	reference set member

as at the specified effectiveTime (field) .

The value must be a

Gloss

Space	true
t	subtype

of

ShowFormat	inline

within the metadata

refsetId (field)

...

SCTID (data type)

...

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

.

...

referencedComponentId (field)

...

SCTID (data type)

...

The identifier of the source

Gloss

Space	true
t	component

of the association.

...

targetComponentId (field)

...

SCTID (data type)

...

The identifier of the target

Gloss

Space	true
t	component

of the association.

Each member of a

Concept

t	900000000000522004\|Historical association\|
ShowFormat	inline

Gloss

represents a Reference from an

Gloss

to other equivalent or related

Gloss

that were current in the

Gloss

Space	true

in which that

Each

holds

. 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 targetComponentId (field) 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 targetComponentId (field) is used differently in the |MOVED TO association

Gloss

t	reference set

|. In this case, the targetComponentId (field) 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 targetComponentId (field) 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.
