MSP-1 — Mark Semantic Protocol

AI-friendly semantics for trusted information
Draft • Version 1.0.0

Mark your content for meaning, trust, and AI understanding.

MSP-1 (Mark Semantic Protocol) is a lightweight standard for exposing sources, verification level, AI usage, and review history in a structured, machine-readable way. It helps AI agents and humans quickly understand how reliable a page is — without changing its editorial voice.

What MSP-1 provides

MSP-1 defines a small, practical set of fields that describe how a page was created, sourced, and reviewed. It is content-neutral and can be adopted by any site that cares about transparency and AI-ready structure.

  • Page-level verification signals (Core, Verified, Authoritative)
  • Structured source lists with access and publish dates
  • Clear disclosure of AI involvement and human review
  • Optional update and review policies for evergreen content
Full specification & documentation coming online soon.

Getting ready to implement

The initial reference implementation of MSP-1 is being deployed on a photography knowledge site as a live proving ground. Once the protocol is exercised in real content, the public spec and examples will finalize.
