Purpose

A

Concept

t	900000000000506000\|Language type reference set\|

supports the representation of

Gloss

PreSpace	false
t	language

and

Gloss

PreSpace	false
t	dialects

preferences for the use of particular

Gloss

PreSpace	false
t	descriptions

. The most common use case for this type of

Gloss

PreSpace	false
t	reference set

is to specify the acceptable and preferred terms for use within a particular country or region. However, the same type of

Gloss

PreSpace	false
t	reference set

can also be used to represent preferences for use of

Gloss

PreSpace	false
t	descriptions

in a more specific context such as a clinical specialty, organization or department.

...

Data structure

A

Gloss

PreSpace	false
t	Language reference set

is a

Gloss

SpacePreSpace	truefalse
t	Component

Gloss

PreSpace	false
t	reference set

that is used to indicate which

Gloss

PreSpace	false
t	descriptions

contain

Gloss

PreSpace	false
t	terms

that are acceptable or preferred in a particular

Gloss

PreSpace	false
t	language

or

Gloss

PreSpace	false
t	dialect

. Its structure is shown in the following table.

Field

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

t	reference set member

became the current version.

The current version of this

Gloss

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

t	reference set member

as at the specified effectiveTime (field) .

If active (field) = 1 (true) the

Gloss

t	reference set member

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

Gloss

t	reference set member

is not part of the current version of the set.

moduleId (field)

SCTID (data type)

Identifies the

Gloss

t	SNOMED CT module

that contains this

Gloss

t	reference set member

as at the specified effectiveTime (field) .

The value must be a

Gloss

t	subtype

of

Concept

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

within the metadata

Gloss

t	hierarchy

.

refsetId (field)

SCTID (data type)

Identifies the

Gloss

t	reference set

to which this

Gloss

t	reference set member

belongs.

In this case, a

Gloss

t	subtype

of

Concept

t	900000000000506000\|Language type reference set\|

.

referencedComponentId (field)

SCTID (data type)

The identifier of a

Gloss

t	description

included in the

Gloss

Space	true
t	language

Gloss

t	reference set

.

acceptabilityId (field)

SCTID (data type)

A

Gloss

t	subtype

of

Concept

t	900000000000511003\|Acceptability\|

indicating whether the

Gloss

t	description

is acceptable or preferred for use in the specified

Gloss

t	language

or

Gloss

t	dialect

.

:

No more than one
Gloss

t description
of a specific
Gloss

may have the

value
Concept
t 900000000000548007|Preferred|
.
Every active concept should have one preferred synonym in each language.
- This means that a language reference set should assign the acceptabilityId
  Concept
  t 900000000000548007|Preferred|
  to one
  Gloss
  PreSpace false
  t synonym
  (a
  Gloss
  PreSpace false

  with
  Specref
  t typeId
  value
  Concept
  t 900000000000013009 | synonym |
  ) associated with each
  Gloss
  PreSpace false
  t concept
  .
- This description is the
  Gloss
  PreSpace false
  t preferred term
  for that
  Gloss
  PreSpace false
  t concept
  in the specified
  Gloss
  PreSpace false
  t language
  or
  Gloss
  PreSpace false
  t dialect
  .
Any
Gloss
PreSpace false
t description
which is not referenced by an active row in the
Gloss
PreSpace false
t reference set
is regarded as unacceptable (i.e. not a valid
Gloss
PreSpace false
t synonym
in the language or
Gloss
PreSpace false
t dialect
).
- If a description becomes unacceptable, the relevant language reference set member is inactivated by adding a new row with the same id, the effectiveTime of the the change and the value active=0.
- For this reason there is no requirement for an "unacceptable" value.
