ISO 25964: Information and documentation – Thesauri and interoperability with other vocabularies will be a two-part standard that updates and revises the existing international standards for monolingual and multilingual thesauri. And not just that: it should also help thesauri to play their full part in access to networked resources, particularly in a Semantic Web context. Part 1 (dealing with the development and establishment of thesauri) is on track for publication in 2011, while Part 2 (focusing on interoperability) is scheduled for completion in 2012. A large part of the content is intended to standardize mapping between one vocabulary and another.
