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

is a

that is used to indicate which

contain

Gloss

PreSpace	false
t	terms

that are acceptable or preferred in a particular

Gloss

PreSpace	false
t	language

or

Gloss

. Its structure is shown in the following table.

:

No more than one
Gloss
PreSpace false

of a specific
Gloss
PreSpace false

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
  t description
  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.
