The MAITS project is a consortium formed to specify an Application Programming Interface (API) for multilingual applications in the telematics services. A number of telematic applications, such as X.500, WWW, X.400, internet mail and data bases, are planned to be enhanced to use this i18n API and products are planned to be implemented using the API.
