eplaced by more descriptive ones if required. To do this, create the new concepts describing the additional
fields under the | Reference set Attribute | metadata hierarchy.
3.3.4.7.5. Representing Subsets as Language type Reference Sets
Language type Reference Sets can be set up in a similar fashion to the above, with the following exceptions:
The LanguageCode field in the Subset record should be used to link the Reference Set's concept into the
appropriate place in the | Language type| metadata sub-hierarchy. For example, a value of "en-US" in the
LanguageCode field would result in the Reference Set's concept being created under |US English|:

ContextId
• Where the SubsetType is " Language" and the LanguageCode is a single level (e.g. "en"), then the
Reference Set should be created at the first level, under |English| in the example above;
• Where the SubsetType is " Language" and the LanguageCode is a two level (e.g. "en-US"), then the
Reference Set should be created at the second level, under |US English| in the example above;
• Where the SubsetType is "Realm Description ", then the Reference Set should be created under RealmId
in the example above (where RealmId is the value of the RealmIdfield in the Subset record);
• Where the SubsetType is "Context Description ", then the Reference Set should be created under ContextId
in the example above (where ContextId is the value of the ContextId field in the Subset record and RealmId
is the value of the RealmIdfield in the Subset record).
The Reference Set member records should be created as described in the following table:
