Key Takeaways:
- YAML-in-HTML embeds structured, trust-scored knowledge directly into web pages.
- Unlike SEO formats like Schema.org, it supports fragment-level memory that AI systems can evaluate independently.
- Works with CMS platforms like WordPress—no plugins or infrastructure changes required.
- Part of the Semantic Digest Protocol, it helps publishers make content retrievable, citeable, and trustworthy for AI.
- Structuring content at the fragment level ensures it exists meaningfully in AI memory.
Why the Web Fails AI Systems
The web was made for people, not machines. Humans interpret context. AI struggles to know what’s true, who said it, and where it came from.
Schema.org and JSON-LD improved SEO, not AI understanding. They operate at the page level, lack provenance, and don’t support claim-level retrieval. AI systems are left guessing.
“Since 2011, websites have used Schema.org and JSON-LD to feed SEO bots. But these formats were never designed for AI memory.” — David Bynon
YAML-in-HTML: A Bridge Between CMS and AI
YAML-in-HTML changes that. It embeds machine-readable, trust-scored memory inside standard HTML using inert tags. No JavaScript. No plugins.

Question-and-answer pairs for retrieval without hallucination. FAQ: question: Are zero-premium Medicare Advantage plans available in all counties? answer: No. Availability varies by county. Directories of entities (e.g., list of Medicare plans). High-level metadata about entire datasets. Just add the block and YAML into a post or page. Embed YAML-in-HTML fragments as partials or template components. Define custom fields or server-side generators that output valid YAML-in-HTML. Key requirement: preserve the and YAML formatting. “If MCP is the USB-C socket, YAML-in-HTML is the micro thumb drive. It’s small, lightweight, and universally pluggable.” — David Bynon Traditional Web: Memory-First Web: YAML-in-HTML brings this future within reach—no new frameworks, no vendor lock-in. It runs on the web we already have. By adding these machine-readable fragments alongside human-readable content, publishers can serve both audiences effectively—ensuring their expertise is accurately represented in both human research and AI-assisted information retrieval.
