INPUT CONVENTIONS
Structure - Other Standard Identifiers are unique, permanent and internationally recognized
alphanumeric codes used to identify works and expressions. The codes may be defined by
the ISO (International Organization for Standardization) and assigned by designated
agencies. Some examples of these identifiers include the ISTC (International Standard
Text Code), the ISWC (International Standard Musical Work Code), and the ISAN
(International Standard Audiovisual Number). The structure of these numbers is
determined by the agencies formulating them.
