Formalized Exchange of Electronic Publications
Formex describes the format for the exchange of data between the Publication Office and its contractors. In particular, it defines the logical markup for documents which are published in the different series of the Offical Journal of the European Union.
Formex V4 is based on the international standard XML (Extensible Markup Language — W3C Recommendation, February 10, 1998). It entered into force on May 1st, 2004. The documentation only exists in English.
