Curator Trust
The discovery and trust layer for agentic booking.
What is Curator?
Curator defines how authorities express their knowledge about collections of venues. Where Venue defines what venues say about themselves, Curator defines what authorities say about them.
Venue → "This is who I am" (venue self-knowledge)
Curator → "This is what I know about them" (third-party observation)
Individual venue claims lack regional context and third-party validation. Curators provide this context.
Curator is a namespace extension to A2A Agent Cards. Curators are agents that can answer questions, recommend venues, and verify claims.
Curator Types
Curator (base)
├── Curator:DMO Regional destination authority
├── Curator:Portfolio Curated collection
└── Curator:Editorial Critics, guides, awards
| Type | Examples | Authority basis |

| Portfolio | Cottages.com, Great British Hotels | Curated selection, booking relationships |
| Editorial | Michelin, AA Rosettes, Good Food Guide | Reputation, editorial judgment |
Core Concepts
Stories
Narratives that reveal place through people. Not marketing copy—real voices, specific details.
Verification
Certification levels and editorial badges that create evidence for venue claims.
Coverage
What the Curator knows about—venue counts, geographic bounds, narrative density.
Actions
What agents can ask: recommend, answer, getStory, listVenues, verify.
Transparency
Required disclosure of economic relationships and ranking methodology.
The Chorus Principle
"The destination doesn't describe itself. Its people do. The Curator's job is to listen and amplify."
Stories create evidence that venues can't create for themselves:
{
"story": {
"type": "venue-interview",
"about": { "venueId": "white-lion-blakeney", "venueName": "The White Lion" },
"content": {
"headline": "Where the sailors drink",
"quotes": [{
"text": "The harbour's been here longer than the building. We're just caretakers.",
"attribution": "James Morton",
"role": "Publican"
}],
"insiderTip": "The crab comes off the boat at 6am. Be at breakfast by 8 if you want it."
}
}
}
The Curator Index
Agents need to discover which Curators exist. The Curator Index is the discovery layer above individual Curators.
The specs define what Curators publish. They do not define who operates the index.
However, the index layer SHOULD be:
| Principle | Why |
|---|---|
| Open | Queryable by any agent without gatekeeping |
| Plural | Multiple indexes can exist and compete |
| Transparent | Index operators publish inclusion criteria |
| Accountable | Index operators are subject to the same principles as Curators |
Whoever operates an index has power over discovery. That power should be legible, contestable, and distributed.
Mutual Validation
Curators and venues validate each other:
Venue validates Curator:
847 venues certified by Visit Norfolk
→ "This DMO has comprehensive coverage"
Curator validates Venue:
Visit Norfolk certified The White Lion
→ Evidence on the venue's record
→ Third-party credibility
This creates natural resistance to spam and fake authorities.
