Purpose

A

Concept
t900000000000506000|Language type reference set|
supports the representation of
Gloss
PreSpacefalse
tlanguage
and
Gloss
PreSpacefalse
tdialects
preferences for the use of particular
Gloss
PreSpacefalse
tdescriptions
. The most common use case for this type of
Gloss
PreSpacefalse
treference set
is to specify the acceptable and preferred terms for use within a particular country or region. However, the same type of
Gloss
PreSpacefalse
treference set
can also be used to represent preferences for use of
Gloss
PreSpacefalse
tdescriptions
in a more specific context such as a clinical specialty, organization or department.

Data structure

A

Gloss
PreSpacefalse
tLanguage reference set
is a
Gloss
SpacePreSpacetruefalse
tComponent
 
Gloss
PreSpacefalse
treference set
that is used to indicate which
Gloss
PreSpacefalse
tdescriptions
contain
Gloss
PreSpacefalse
tterms
that are acceptable or preferred in a particular
Gloss
PreSpacefalse
tlanguage
or
Gloss
PreSpacefalse
tdialect
. Its structure is shown in the following table.

Language Reference Rules and Guidance

In a

Gloss
PreSpacefalse
tLanguage reference set
:

  • No more than one
    Gloss
    PreSpacefalse
    tdescription
    of a specific
    Gloss
    PreSpacefalse
    tdescription type
    associated with a single
    Gloss
    PreSpacefalse
    tconcept
    may have the
    Specref
    RefType(field)
    tacceptabilityId
    value
    Concept
    t900000000000548007|Preferred|
    .
  • Every active concept should have one preferred synonym in each language. 
    • This means that a language reference set should assign the acceptabilityId 
      Concept
      t900000000000548007|Preferred|
       to one 
      Gloss
      PreSpacefalse
      tsynonym
       (a 
      Gloss
      PreSpacefalse
      tdescription
      with 
      Specref
      ttypeId
       value
      Concept
      t900000000000013009 | synonym |
      ) associated with each
      Gloss
      PreSpacefalse
      tconcept
      .
    • This description is the
      Gloss
      PreSpacefalse
      tpreferred term
      for that
      Gloss
      PreSpacefalse
      tconcept
      in the specified
      Gloss
      PreSpacefalse
      tlanguage
      or
      Gloss
      PreSpacefalse
      tdialect
      .
  • Any 
    Gloss
    PreSpacefalse
    tdescription
     which is not referenced by an active row in the  
    Gloss
    PreSpacefalse
    treference set
     is regarded as unacceptable (i.e. not a valid 
    Gloss
    PreSpacefalse
    tsynonym
     in the language or 
    Gloss
    PreSpacefalse
    tdialect
     ).
    • 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.
