Changing and Removing Unit Names
Each collection requires a valid unit when created or saved. Removing a unit from the unit list will not remove the unit from each collection. However, collections that have the old unit name will require selecting a new unit name before the collection can be saved.The purpose of the unit vocabulary is to ensure that collections are saved with a proper unit. Changing or removing unit names in the controlled vocabulary file will not update or remove those unit names from collections.
