UCNG · Universal Content Notation Guidelines

Declare how content was made.

UCNG is an open notation framework for transparent content declarations – readable by humans and machine-readable for platforms and systems. This application generates the declaration, badge and JSON-LD from the same information.

UCNG badge

https://ai.trustednet.eu/badge/research.svg?lang=en

The badge is the compact representation of a UCNG Declaration. It indicates that a declaration exists; it does not automatically mean verified, certified or legally compliant.

JSON-LD

Machine layer

https://ai.trustednet.eu/v1/declaration.json?preset=research&lang=en

The structured JSON-LD representation carries the same declaration data in a machine-readable form for platforms, systems and build workflows.

Stateless

No sessions and deterministic responses. Designed for horizontal scaling, reverse proxies and CDNs.
