Regulatory Timeline

August 2, 2026 — Compliance deadline for:

  • EU AI Act Article 50 — AI-generated content labeling and transparency
  • California SB 942 — AI-generated content disclosure requirements

AIOSchema is designed to provide a compliant provenance layer ahead of this deadline. The standard is available today for early adoption and integration testing.

Principles

This roadmap describes direction, not commitments. The KISS principle governs all additions: every feature added to the standard must justify its complexity cost. Minimalism is mathematically necessary — any addition adds dependency, any dependency adds attack surface.
