ISNI is used for identifying contributors to creative works and those active in their distribution, including researchers, inventors, writers, artists, visual creators, performers, producers, publishers, aggregators, and more. As ISO 27729, it is part of a family of international standard identifiers that includes identifiers of works, recordings, products and right holders in all repertoires.
