1. Stable Foundations

MSP-1 begins with stability at the most fundamental level:

• Permanent namespace: https://msp-1.org/ns#
• Stable IRIs for all terms regardless of site or system
• Versioned schemas that evolve without breaking existing sites
• Profiles (Site, Page, Provenance) instead of monolithic formats

These choices make MSP-1 resilient in a rapidly changing metadata landscape.

2. Modular, Extensible Profiles

Instead of defining a single, rigid metadata object, MSP-1 uses a flexible profile system. This ensures long-term adaptability:

• Site Profile — identity, authority, role, and scope
• Page Profile — intent, context, and meaning
• Provenance Profile — authorship, review, sources, and AI assistance

Additional profiles MAY be introduced in future versions without breaking legacy implementations.

3. AI-First Architecture

As AI agents and answer engines evolve, MSP-1 will continue to serve as a stable interpretive layer:

• Clear signals of identity and authority reduce ambiguity in AI responses
• Structured provenance improves reliability in high-stakes content
• Intent modeling ensures accurate summarization and contextualization
• AI usage transparency aligns with emerging global standards

MSP-1 ensures your content remains understandable and trustworthy even as models change.

4. Long-Term Content Resilience

By separating content from metadata, MSP-1 improves durability across:

• Full site redesigns
• CMS platform migrations
• Search engine/AI shifts
• URL structure changes

MSP-1 metadata can survive even if the technical implementation underneath it changes completely.

5. Open Protocol Governance

MSP-1 is designed to be platform-neutral, implementation-agnostic, and openly governed. This supports:

• Collaborative evolution
• Vendor-neutral adoption
• Long-term accountability
• Transparent change logs and versioning
