About reference data

Reference data, such as code lists and authority tables, means data that are used to characterise or relate to other data. Such a controlled vocabulary defines the permissible values to be used in a specific field for example as metadata. Reference data vocabularies are fundamental building blocks of most information systems. Using common interoperable reference data is essential for achieving interoperability.
