Official Namespace Definitions for Human-Origin Metadata
The Grady Vocabulary is a standardized set of machine-readable properties designed to bridge the trust gap between biological human authority and the synthetic AI-driven future. As an extension of the Schema.org global standard, this namespace provides the essential technical vocabulary for anchoring digital entities to verifiable, human-led origins.
By utilizing the Grady Protocol v2.0.0, broadcasters, journalists, creators, and professional services can provide a high-authority 'Digital Passport' that allows search crawlers and Large Language Models (LLMs) to identify, verify, and prioritize authentic human content over machine-generated noise.
