"The Roles name authority list (NAL) or authority table is a controlled vocabulary listing the roles relevant for the descriptive metadata used at the Publications Office and the core metadata used in the data exchange between the institutions involved in the legal decision making process. It is also used by EUR-Lex.
The table provides an authority code, the start-use date and labels in all official EU languages.
The Roles NAL is part of the Core Metadata (CM) used in the exchange between the institutions involved in the legal decision making process and the Publications Office of the EU. The NAL is under governance of the Interinstitutional Metadata Maintenance Committee (IMMC) and maintained by the Publications Office of the EU in its Metadata Registry (MDR)."
