Whenever a new description is added to SNOMED CTin an extension, the language preferences associated with that description must also be specified. Naturally this applies to extension specific descriptions which have been added to establish a preferred term within a country or region. When used in a national or local edition, this specification can override the language preferences established in the International Edition. The technical specifications are defined by adding the associated This is done by adding rows to a language reference set to indicate a description is acceptable or preferred in a particular whether each description is

in the given language or dialect.
Attributes
As previously mentioned, all reference sets use six common attributes. In addition to these, a

reference sets use one additional attribute which is acceptabilityId. A description of how these attributes are applied to language sets is provided in below also includes an acceptabilityId. The table below explains how each of these attributes is populated in a | Concept |

Note that a prerequisite to specifying the language preferences for a given description is the establishment of the language reference set itself. Practically speaking, a language refset set has been established once - The reference set concept has been created (along with it's associated components and derivatives)
- Individual members of the refset have been defined in refset rows
- A language refset file has been generated (in RF2 format) and published
|
for the given language or dialect. |
| Info |

|
Note some extension producers may need to establish separate create and populate more than one language reference setsset. For example, one for language translations and another for the addition of where different languages or dialects are used within a country, or where both clinician and patient friendly terms must be specified. |

Key points as followsPlease note the following:
- The id column shows a UUID that has been uniquely generated for each refset member.
- The moduleId indicates that these refset members are included in belong to the
