. The most common use case for this type of

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

|
can also be used to represent preferences for use of

A Language reference set is a Component reference set that is used to indicate which
| Gloss |

|---|
| t | descriptions |

|
contain
that are acceptable or preferred in a particular
or
. Its structure is shown in the following table.

Purpose
...
id
...
UUID
...
A 128 bit unsigned integer, uniquely identifying this reference set member .
Different versions of a reference set member share the same id but have different effectiveTimes. This allows a reference set member to be modified or made inactive (i.e. removed from the active set) at a specified time.
...
effectiveTime
...
Time
...
The inclusive date or time at which this version of the identified reference set member became the current version.
The current version of this reference set member at time T is the version with the most recent effectiveTime prior to or equal to time T .
...
active
...
Boolean
...
The state of the identified reference set member as at the specified effectiveTime .
If active = 1 (true) the reference set member is part of the current version of the set, if active = 0 (false) the reference set member is not part of the current version of the set.
...
moduleId
...
SCTID
...
Identifies the SNOMED CT module that contains this reference set member as at the specified effectiveTime .
The value must be a subtype of 900000000000443000 $$ Module (core metadata concept) $$ within the metadata hierarchy .
...
refsetId
...
SCTID
...
Identifies the reference set to which this reference set member belongs.
In this case, a subtype of 900000000000506000 $$ Language type reference set $$ .
...
referencedComponentId
...
SCTID
...
The identifier of a description included in the language reference set .
...
acceptabilityId
...
SCTID
...
A subtype of 900000000000511003 $$ Acceptability $$ indicating whether the description is acceptable or preferred for use in the specified language or dialect .

|
. - 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 (a | Gloss |

) associated with each . - This description is the
| Gloss |

|
for that in the specified or .
- 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 in the language or ).- 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.
