The international standard ISO 233 establishes a system for romanization of Arabic script.
It was supplemented by ISO 233-2 in 1993 which is specific for Arabic language.
ISO 233-2:1993 is an ISO schema for the simplified transliteration of Arabic characters into Roman characters and is dedicated to "Arabic language – Simplified transliteration".
According to ISO 233-2(1993), Arabic words are vocalized prior to romanization.
ISO 233-2 is used in French libraries[1] and in North African libraries, and is recommended by ISSN for establishing key titles when cataloguing serials.
