"The treaty authority table is a controlled vocabulary listing the different EU treaties, including treaties and protocols, accession treaties, Schengen Convention and Charter of Fundamental Rights. It provides an authority code, the start-use date of the concept and labels in all official EU languages.
The treaty authority table gives the day and the location of the signature of a treaty with reference to place authority table, excluding the consolidated versions as well as the acts concerning the conditions of accession and the Charter of Fundamental Rights of the European Union.
This table is part of the core metadata used in the exchange between the institutions involved in the legal decision-making process and the Publications Office of the European Union. It is also used by EUR-Lex. The treaty authority table is under governance of the Interinstitutional Metadata Maintenance Committee (IMMC) and maintained by the Publications Office of the European Union in the Metadata Registry (EU Vocabularies website)."
