Show HN: AI Domain Data Standard – Self-Hosted, DNS-Based Identity for AI (github.com)

The repo releases v0.1 of the AI Domain Data standard — an open, vendor-neutral format for authoritative domain metadata that publishers self-host at https://<domain>/.well-known/domain-profile.json (with an optional DNS TXT mirror at _ai.<domain> carrying ai-json=<base64(JSON)>). It’s designed so AI systems, search engines, and automated agents can reliably discover publisher identity, provenance, and policy metadata, improving attribution, content filtering, and trust signals across models and crawlers. The project packages a human-readable spec, JSON schema, outreach docs, and reference tooling to jumpstart adoption. Technically, the repo contains a canonical spec (spec-v0.1.md) and JSON schema (schema-v0.1.json, optional entity_type), a React/Vite generator and visibility checker, shared components, a CLI (aidd) for init/validate/emit workflows, and a Node/TypeScript resolver SDK for runtime discovery. It’s MIT-licensed and organized to support three rollout phases: Brand+Spec+Proof, Distribution+Influencers, and Minimal Implementation, with future integrations (WordPress plugin, GitHub Action, Cloudflare Worker) planned. For developers, the workspace can be run locally (npm install; npm run dev --workspace @ai-domain-data/site) and the CLI/resolver packages built for self-hosted workflows, enabling straightforward publisher adoption and automated resolver integration into AI stacks.
