Fields marked as authority or controlled list in the schema are linked to existing vocabularies, authority files (one or more vocabularies), or controlled lists (non-hierarchical or flat vocabularies). Institutions may configure the display option (auto complete, predictive text, dropdown), default value, validation requirements, and source vocabularies for a vocabulary-enabled field. Static controlled lists may only have terms added programatically; Dynamic term lists may be edited via the UI.
If the associated field on a data entry form is configured to allow terms to be added, then the user will be able to add a term to the source vocabulary list. If the associated field on a data entry form is configured to allow terms to be added AND the field is associated with multiple sources, then the user will be able to add a term and identify the source vocabulary list the term should be added to.
