ISO norms are created by the International Organization for Standardization. The organization has published more than nineteen thousand international standards covering all aspects of technology and business. The standards are developed by topic, such as information and documentation. They are written and supervised by a committee of experts and offer internationally acclaimed rules and procedures. The ISO 25964-1:2011 (part 1) for example, contains valuable information on thesauri and interoperability with other vocabularies.
