The standard
Specifications
37 documents. Each names the terms it owns, states its own version, and may not redefine anything another document already settled. Every one is a Working Draft.
Foundation
Mission, architecture, terminology, and the trust, security, lifecycle and versioning models everything else rests on.
Core
What a News Object is, how it is named and serialized, how it is signed, validated, and retrieved. Core alone decides authenticity.
Companion
Domain object models layered on Core: articles, media, identity, rights, payments, sources, corrections, comments.
Extension
Additive claims attached to an object: AI metadata, search, analytics, geolocation, accessibility.
Reference
Implementation guidance, best practices, security checklist, performance, migration, and interoperability with existing standards.
