ISO has officially published the International Standard Name Identifier (ISNI), a 16-digit code for the identification of public identities across multiple fields of activities. ISNIs are assigned to the public identities of parties that participate in the creation, production, management or distribution of cultural goods in the digital environment. It streamlines distribution chains, disambiguating natural, legal and even fictional parties that might otherwise be confused. ISNI's founding members are the Bibliothèque nationale de France, the British Library, the conference of European National Librarians, the International Confederation of Societies of Authors and Composers (CISAC), the International Federation of Reproduction Rights Organisations (IFRRO), the International Performers Database Association, OCLC and ProQuest.
