Whenever a new description is added in an extension, the language preferences associated with that description must be specified. This is done by adding rows to a language reference set to indicate whether each description is |acceptable| or |preferred| in the given language or dialect.
As previously mentioned, all reference sets use six common attributes. In addition to these, a |Language type reference set| also includes an acceptabilityId. The table below explains how each of these attributes is populated in a |Language type reference set|.
|Attribute||Data Type||Use in a Language Reference Set|
Can be generated using a standard UUID generator.
|effectiveTime||Time||Specifies the date on which this version of the reference set member was released.|
Indicates whether or not the reference set member is active at the given effectiveTime. This value is set to "1" for new reference set members.
|moduleId||SCTID||Identifies the module to which this reference set member belongs. For members in an extension, this will always be a module created by the extension producer.|
This refers to the concept id of a descendant of |Language type reference set| and represents the language or dialect for which the preferences are defined. The reference set concept may be created in the extension, or may belong to a module on which the extension depends (e.g. the international core module).
The referencedComponentId refers to the id of the description whose acceptability is being defined.
In Figure 220.127.116.11.1-1 below, two rows from the 20581000087109 |Canada French language reference set| are shown. Note that these rows specify French Canadian language preferences for the concept |Herpes labialis|.
