Document identifier format Named Authority List

The Document identifier format authority file describes the standardised syntax of the identifiers of documents produced by the institutions of the European Union in particular. This authority file was created to be used by metadata in the AKN4EU mark-up language. It provides for each identifier marked a mapping with a standardised syntax with a decomposition into the subcomponents and for each subcomponent a meaning depending on the type of identifier. Each institution can have its own naming convention and is allowed to map it according to its own naming convention inside the text.The Document identifier format authority file is maintained by the Publications Office of the European Union on EU Vocabularies website.
