Ontology-driven schemas for AI-readable websites.
META-AIML v3.0.0 publishes a canonical schema system built from ontology, interaction archetypes, shared components, entity contracts, filled examples, and a validator SDK with explicit score gates.

Static contract, live sources
v3 is designed for one stable JSON-LD object in the site head, while fast-changing data stays behind declared source URLs.
Published schema sets
v3 separates foundational contracts from filled instances. That keeps composition predictable and makes validation rules explicit.
Operational model
The v3 architecture is optimized for publish-once schemas that remain stable while AI agents fetch fresh operational data from declared sources.
Choose the contract
Start from the correct ontology mode, archetype, and entity schema before filling business data.
Keep dynamic data external
Menus, catalogs, prices, and ratings should be linked as live sources instead of hard-coded snapshots.
Validate before publish
The SDK validator and Playground share the same validation core and score semantics.
Menu feeds, product catalogs, and review data are modeled as source descriptors, not as embedded snapshots. This reduces manual maintenance and lets downstream agents fetch current values.

}Core tooling
The website, public schema host, and validator distribution now point to the same v3 contract family.
