Fields are the primary elements of a library's structure. A field is a holder for a unit of data, or value. Every field has a name, a type, and a role. Individual field types may have additional attributes.
Fields are created and edited during the editing of a library.
The sequence of fields within the library is significant. The Order in which the fields are displayed on the Field View Card and the Field Edit Card is based on their order within the Fields tab in the library.
