Screenshot of GUI for metadata administration page. Users who have admin privileges may add new events or customize an existing event using this metadata administration page. The page allows users with admin privileges to modify existing fields or add new fields. Users may perform actions such as mark fields as ‘active’ or they may mark them ‘inactive’ to deprecate a field. They may set whether a field is required or optional, set the input style in default options, set field description, set max field length, set ontology class and set field position on the event page
