MSP-1 Reference Tools

Public tools that support correct implementation of the Mark Semantic Protocol (MSP-1).

Multiple independent Schema Architect implementations exist, each producing identical, standards-compliant MSP-1 output. These tools are optional reference implementations. The specification and schema remain canonical.

MSP-1 Declaration Builder

Build page-level and site-level MSP-1 declarations through a guided step by step workflow. Define scope, identity, meaning, provenance, and trust while viewing the generated declaration live. No JSON authoring required, and all processing remains in your browser.
