Akoma Ntoso, a.k.a. LegalDocML, is a Committee Specification of OASIS, carried out by the OASIS LegalDocML Technical Committee. Akoma Ntoso is an XML legal formalism for the markup of literal content of any paper-based document.

Akoma Ntoso was partially inspired by CEN Metalex and it is currently used by a large set of institutions (see the full list here). The latest published version of Akoma Ntoso schema is Akoma Ntoso 3.0.

Akoma Ntoso defines a set of simple technology-neutral electronic XML markup of parliamentary, legislative, and judiciary documents, debate records, standards, and other requirements specification.

Akoma Ntoso stores metadata into a special XML section of the XML document, which is kept separate from the structural content of the document. The section is organized according to the open standard FRBR (Functional Requirements for Bibliographic Records) entity-relationship model. Pointers from the section to the structural elements of the content allow to link the conceptual descriptions with the excerpts of texts denoting them, thus enabling semantic searches on the text and facilitating cataloging of the information.
