Akoma Ntoso for European Union (AKN4EU)

The future machine-readable structured format for the exchange of legal documents in the EU decision-making process

It is widely accepted that the use of common formats greatly facilitates the exchange and reuse of information: common formats enable interoperability. The adoption of common formats increases efficiency and quality as well as facilitating synergies between the entities involved. This is particularly true for legislative documents produced by the EU institutions during the interinstitutional legislative process.

Since 2018 the Interinstitutional Metadata and Formats Committee (IMFC) has been tasked with developing and maintaining common interinstitutional standards for the secured and automated exchange of data based on machine-readable structured formats for content and metadata.

AKN4EU is based on XML, and more specifically on Akoma Ntoso, an OASIS standard, and should serve as the specification for all future exchanges of legal documents. The scope of the current version includes legal acts adopted through the ordinary legislative procedure. The IMFC will further develop and maintain AKN4EU as the interinstitutional standard for the exchange of structured content.

The use of AKN4EU and the IMFC’s continued work to promote the implementation of a seamless automated workflow will bring benefits in terms of greater simplification, effectiveness, efficiency and security in the exchange of legal data.
