Akoma Ntoso V2.0 wins OASIS Standard approval for legal documents

OASIS Open approved Akoma Ntoso Version 2.0 Part 2, or AKN 3.1, as an OASIS Standard for machine-readable legal and legislative documents. The update adds broader judicial, multilingual and metadata support, while giving European institutions a stronger base for EU legal document exchange.

Why it matters: - Akoma Ntoso is a core open standard for machine-readable legislation, debate records, minutes and court judgments. - The new OASIS Standard strengthens legal document interoperability for parliaments, courts, publishers and public institutions. - The update matters for multilingual and cross-border legal workflows, including European Union document exchange.

What happened: - OASIS Open announced that Akoma Ntoso Version 2.0, Part 2: Specifications, defining AKN 3.1, has been approved as an OASIS Standard. - The standard was developed by members of the OASIS LegalDocumentML Technical Committee from industry, government and academia. - The release was announced in Boston on October 13, 2026.

The details: - Akoma Ntoso means “linked hearts” in the Akan language of West Africa. - The XML vocabulary standardizes parliamentary, legislative and judicial documents. - The project is marking 20 years since its founding in South Africa. - UNDESA supported the project’s early development. - Prof. Fabio Vitali and Prof. Monica Palmirani of the University of Bologna serve as co-chairs of the OASIS LegalDocML TC. - AKN 3.1 expands the AKN V3.0 framework without changing the vocabulary’s overall architecture. - The update adds new structural containers, including schedules, annexes, appendices and cross-headings. - The release adds witness, court and judgmentSummary elements. - Judicial documents now get a more structured table of contents. - Multilingual support now includes non-Gregorian calendar dates and a new element for foreign-language passages. - Metadata coverage is more precise across definitions, recitals and citations. - Prof. Monica Palmirani said the update reflects years of real-world feedback from courts and legislative publishers and improves the modeling of complex text changes and legal temporal representation. - Marc Vanderperren, Head of Unit, Data and Format Standardisation Services at the Publications Office of the European Union, said the approval is an essential milestone for further development of Akoma Ntoso for European Union use as AKN4EU.

Between the lines: - The approval signals that Akoma Ntoso has moved from a niche legal-technology effort to a mature global standard with broad institutional backing. - The European Union’s interest suggests the standard is becoming more important for official document exchange in multilingual government systems. - The focus on judicial structure and metadata shows that legal standards are moving beyond plain text toward richer, machine-processable legal records.

What's next: - The OASIS Standard and related files are available for download. - The LegalDocML TC is seeking participation from parliaments, courts, legal publishers, contract management organizations, ICT vendors and other interested organizations. - Participation is open through OASIS membership, and interested groups can contact join@oasis-open.org. - European institutions are expected to continue developing AKN4EU as the machine-readable structured format for EU legal document exchange.

The bottom line: - Akoma Ntoso 3.1 gives legal and legislative systems a more complete, multilingual and interoperable foundation for machine-readable law.
