Codelists

Summary

Classifications used in the standard

Description

Codelists are lists of terms that are provided as part of a standard in order to ensure that values of fields where there are a limited range of options are properly limited in the data, and that concepts map correctly between datasets. For example, a codelist might specify currency codes, to avoid US Dollars being referred to as “$” in one data set and “USD” in another. Codelists can be open or closed - open codelists allow values to be added, while closed codelists do not permit additions

Prioritisation Factors

• If there are currencies, languages or other commonly enumerated concepts in the standard

• If there are data elements that would be rendered as ‘pick one from the list’ in a form
