Data structure

An

Gloss
SpacePreSpacetruefalse
tAssociation reference set
is a
Gloss
Spacetrue
tComponent
PreSpacefalse
Gloss
Spacetrue
treference set
used to represent associations between
Gloss
PreSpacefalse
tcomponentcomponents
. Its structure is shown in the following table.

Purpose

...

Specref
RefType(field)
tid

...

Specref
RefType(data type)
tUUID

...

A 128 bit unsigned

Specref
RefType(data type)
tInteger
, uniquely identifying this
Gloss
treference set member
.

Different versions of a reference set member share the same

Specref
RefType(field)
tid
but have different
Specref
RefType(field)
teffectiveTime
. This allows a reference set member to be modified or made
Specref
RefType(field)
tactive
(i.e. removed from the active set) at a specified time.

...

Specref
RefType(field)
teffectiveTime

...

Specref
RefType(data type)
tTime

...

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

Gloss
Spacetrue
treference set member
became the current version.

The current version of this

Gloss
Spacetrue
treference set member
at time T is the version with the most recent
Specref
RefType(field)
teffectiveTime
prior to or equal to time T .

...

Specref
RefType(field)
tactive

...

Specref
RefType(data type)
tBoolean

...

The state of the identified

Gloss
Spacetrue
treference set member
as at the specified
Specref
RefType(field)
teffectiveTime
.

If

Specref
RefType(field)
tactive
= 1 (true) the
Gloss
Spacetrue
treference set member
is part of the current version of the set, if
Specref
RefType(field)
tactive
= 0 (false) the
Gloss
Spacetrue
treference set member
is not part of the current version of the set.

...

Specref
RefType(field)
tmoduleId

...

Specref
RefType(data type)
tSCTID

...

Identifies the

Gloss
Spacetrue
tSNOMED CT module
that contains this
Gloss
Spacetrue
treference set member
as at the specified
Specref
RefType(field)
teffectiveTime
.

The value must be a

Gloss
Spacetrue
tsubtype
of
Concept
t900000000000443000|Module (core metadata concept)|
ShowFormatinline
within the metadata
Gloss
thierarchy
.

...

Specref
RefType(field)
trefsetId

...

Specref
RefType(data type)
tSCTID

...

Identifies the

Gloss
Spacetrue
treference set
to which this
Gloss
Spacetrue
treference set member
belongs.

In this case, set to a

Gloss
Spacetrue
tsubtype
of
Concept
t900000000000521006|Association type reference set|
. This indicates the nature of the association between the source and target
Gloss
tcomponents
.

...

Specref
RefType(field)
treferencedComponentId

...

Specref
RefType(data type)
tSCTID

...

The identifier of the source

Gloss
Spacetrue
tcomponent
of the association.

...

Specref
RefType(field)
ttargetComponentId

...

Specref
RefType(data type)
tSCTID

...

The identifier of the target

Gloss
Spacetrue
tcomponent
of the association.

Each member of a

Concept
t900000000000522004|Historical association|
ShowFormatinline
Gloss
Spacetrue
treference set
represents a Reference from an
Gloss
Spacetrue
tinactive component
to other equivalent or related
Gloss
Spacetrue
tcomponents
that were current in the
Gloss
Spacetrue
tRelease Version
in which that
Gloss
Spacetrue
tcomponent
was inactivated.

Each

Concept
t900000000000522004|Historical association|
ShowFormatinline
Gloss
Spacetrue
treference set
holds
Gloss
Spacetrue
tRelationships
of a different nature between the
Gloss
tcomponents
. The 
Concept
t900000000000522004|Historical association|
ShowFormatinline
Gloss
Spacetrue
treference set
contains associations:

  • from each

    Gloss
    Spacetrue
    tinactive description
    to one or more other
    Gloss
    Spacetrue
    tDescriptions
    that are current in the
    Gloss
    Spacetrue
    trelease Version
    in which the
    Gloss
    Spacetrue
    tdescription
    was inactivated;

  • from each inactive

    Gloss
    Spacetrue
    treference set
    for which there is a current replacement to the replacement
    Gloss
    treference set
    ;

  • from an

    Gloss
    Spacetrue
    tinactive description
    to a
    Gloss
    Spacetrue
    tconcept
    that is current in the
    Gloss
    Spacetrue
    tRelease Version
    in which the
    Gloss
    Spacetrue
    tdescription
    was inactivated, and which is correctly described by the Term of the
    Gloss
    tinactive description
    ;

  • From each

    Gloss
    Spacetrue
    tinactive concept
    to one or more
    Gloss
    Spacetrue
    tconcepts
    that replace it.

The

Gloss
Spacetrue
tcomponent
identified by the
Specref
RefType(field)
ttargetComponentId
must be an instance of the same class of
Gloss
Spacetrue
tcomponent
as the
Gloss
Spacetrue
tcomponent
identified by the referencedComponentIdfor all |Historical association|
Gloss
Spacetrue
treference sets
apart from the |REFERS TO
Gloss
Spacetrue
tconcept
association
Gloss
treference set
|.

Within the |REFERS TO

Gloss
Spacetrue
tconcept
association
Gloss
treference set
|, the referenced ComponentId field must be a
Gloss
Spacetrue
tdescription
and the targetComponentIdmust be a
Gloss
tconcept
.

The

Specref
RefType(field)
ttargetComponentId
is used differently in the |MOVED TO association
Gloss
treference set
|. In this case, the
Specref
RefType(field)
ttargetComponentId
does not refer directly to a replacement
Gloss
tcomponent
, but rather to the namespace to which the
Gloss
Spacetrue
tcomponent
was moved to. The
Specref
RefType(field)
ttargetComponentId
actually refers to the
Gloss
Spacetrue
tconcept
that represents the namespace. This approach is used since the organization sourcing the
Gloss
Spacetrue
tcomponent
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.
