Introduction

Akoma Ntoso is the OASIS standard (LegalDocML) that defines an XML vocabulary for parliamentary, legislative and judiciary documents. This site is a verbatim, word-for-word reference for the Akoma Ntoso document family, built from the OASIS published deliverables with no paraphrase: every page mirrors the source tables and rows, and build-time checks verify word-level integrity for the rendered documents. The left sidebar groups every published document separately: one entry per document, nothing interleaved; this page is the standalone entry point.

Use this site to:

• look up any AKN 3.1 element, complex type, simple type, element group, attribute group or attribute as an atomic page with its verbatim annotations, facets, children and XML examples (Part 2 group);

• read the full specification prose (Part 2: Specifications of AKN 3.1, OASIS Standard 2026), the Part 1 XML Vocabulary (OASIS Standard 2018, the AKN 3.0 era document) and the Naming Convention (NC v1.0, OASIS Standard 2019) word-for-word;

• download the schema files (akomantoso30.xsd, xml.xsd) shipped with the v2.0 package for Level-1 validation, and follow the assembly guides for complete documents (act, judgment).

• call the same knowledge base from software: the read-only MCP server and REST API are documented in MCP & REST API.

Document coverage

Where each artefact of the Akoma Ntoso family lives. This site carries Part 2: Specifications of AKN 3.1 (element/type/attribute reference above, plus the specification prose under Specification & Notices) and Part 1: XML Vocabulary (OASIS Standard 2018) (verbatim prose under Part 1: AKN 3.0 era; see the Part 1 index).

Document	Version / Date	Status	Availability
Part 2: Specifications of AKN 3.1	AKN 3.1: 2 October 2026	OASIS Standard (current)	This site: full content
Part 1: XML Vocabulary	Akoma Ntoso v1.0: 29 August 2018	OASIS Standard of the AKN 3.0 era; Akoma Ntoso 2.0 does not include a Part 1	This site: verbatim prose (Part 1 index) · OASIS docs
Akoma Ntoso Naming Convention	NC v1.0: 06 June 2017	OASIS Committee Specification 01; normatively referenced by Part 2 conformance (Level 2: eId/wId + FRBR naming)	This site: verbatim prose (NC index) · OASIS docs
AKN4UN	UN localization guidelines	UN HLCM practice documents for UN material: separate from the OASIS standard parts	unsceb-hlcm.github.io

Namespace history

Namespace URI	Used by	Notes
http://docs.oasis-open.org/legaldocml/ns/akn/3.0	AKN 3.0 (OASIS Standard 2018) and AKN 3.1 (OASIS Standard 2026)	Stable namespace URI; targetNamespace of akomantoso30.xsd. The URI resolves to the XML namespace document.
Legacy pre-OASIS AKN namespaces	Documents from the community era (pre-2011)	Old deployments only; not covered by this site

Site note: specification URI vs schema target namespace. The LegalDocML TC defines AKN 3.1 as a backwards-compatible incremental extension of AKN 3.0, so the distributed schema file keeps the name akomantoso30.xsd and its targetNamespace http://docs.oasis-open.org/legaldocml/ns/akn/3.0, while the specification URI of AKN 3.1 is http://docs.oasis-open.org/legaldocml/ns/akn/3.1: a policy-driven split between the conceptual identifier (namespace document, Part 2 §7) and the physical XSD declaration. This is why the element and attribute pages above list ns/akn/3.0 as the namespace even under the AKN 3.1 specification. For Level-1 syntax validation, bind the parser to the v2.0 akomantoso30.xsd through an XML Catalog mapping so that instances declaring either URI validate against the same schema. See Schemas & Validation.
