What’s included

  • The complete AIOSchema v0.5.5 specification
  • Reference implementations in Python (108 tests) and TypeScript (70 tests)
  • A cross-verified conformance suite with 14 deterministic test vectors
  • Additional implementations in Node.js, Go, and Rust

What is AIOSchema?

AIOSchema is an open, technology-agnostic standard for verifying the integrity, authenticity, and provenance of digital and physical assets. It provides a minimal, verifiable metadata framework — the universal provenance layer for digital content — designed to be read in one hour and implemented in one day.

Why now?

The EU AI Act Article 50 and California SB 942 establish content labeling requirements effective August 2, 2026. AIOSchema provides a free, open, and neutral provenance layer suitable for regulatory compliance.

Get involved

AIOSchema v0.5.5 is designated as a Technical Preview. The Core Block fields are architecturally frozen.
