0545 Reference Data

Reference data provides authoritative definitions of valid values for data.

The list of valid values can be modelled directly in open metadata using the ValidValuesSet entity with one or more ValidValue entities linked off of it. There is one ValidValue entity instance for each of the valid values.

Typically the valid values set is linked off of a GlossaryTerm or a SchemaElement.

A valid values set can also be implemented in an asset that can be used as a look up table while data is being processed.
