A 900000000000506000 |Language type reference set| supports the representation of language and dialects preferences for the use of particular descriptions. The most common use case for this type of reference set is to specify the acceptable and preferred terms for use within a particular country or region. However, the same type of reference set can also be used to represent preferences for use of descriptions in a more specific context such as a clinical specialty, organization or department.
A Language reference set is a Component reference set that is used to indicate which descriptions contain terms that are acceptable or preferred in a particular language or dialect. Its structure is shown in the following table.
Reference Set Types in the Metadata Hierarchy (2018-01-31)
In a Language reference set:
No more than one description of a specific description type associated with a single concept may have the acceptabilityId value .
Every active concept should have one preferred synonym in each language.
This means that a language reference set should assign the acceptabilityId to one synonym (a description with typeId value ) associated with each concept .
The following metadata supports this reference set :
Language References Sets in the Metadata Hierarchy
The immediate children of will represent languages. This level may be used to represent the "formal approved" language, where a language authority is formally recognized. In most cases, this level will not identify a specific reference set. Subtype of the language level are used to represent different dialects, national or regional variants.
The table below shows an example of the descriptor for a specific reference sets that follows the pattern.

Sample content from the GB English language reference set
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.
YES
NO
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 within the metadata hierarchy.
YES
NO
refsetId
SCTID
Identifies the reference set to which this reference set member belongs.
In this case, a subtype descendant of:
NO
NO
referencedComponentId
SCTID
A reference to the SNOMED CT component to be included in the reference set. Refers to the description to which the acceptability value is being applied.
NO
NO
acceptabilityId
SCTID
A subtype of indicating whether the description is acceptable or preferred for use in the specified language or dialect .
YES
NO
Any description which is not referenced by an active row in the reference set is regarded as unacceptable (i.e. not a valid synonym in the language or 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 change and the value active=0.
For this reason there is no requirement for an "unacceptable" value.
0
1
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 effectiveTime. This allows a reference set member to be modified or made inactive (i.e. removed from the active set) at a specified time.
NO
YES (Full /Snapshot)
effectiveTime
Time
The inclusive date or time at which this version of the identified reference set member became the current version.
Note: In distribution files the effectiveTime should follow the short ISO date format (YYYYMMDD) and should not include the hours, minutes, seconds or timezone indicator.
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.
YES
