[mikeslone]

Closes / relates to #11

Files

File	Intended live URL
conformance/examples/snowdata-ai-catalog.json	https://www.snowdata.ai/.well-known/ai-catalog.json
conformance/examples/snowsure-ai-catalog.json	https://www.snowsure.ai/.well-known/ai-catalog.json
conformance/examples/mcp-snowdata-ai-catalog.json	https://mcp.snowdata.ai/.well-known/ai-catalog.json

Design notes

• ADR-0003 compliant: federation uses nested application/ai-catalog+json entries with url — no root collections array
• Representative queries: 2–5 per entry for semantic search indexing
• Vertical: snow / ski / travel — MCP live conditions, OpenAPI REST, grounded Answer Engine, ARD search registry

Conformance

./conformance/bin/conformance-test manifest conformance/examples/snowdata-ai-catalog.json
# CONFORMANCE STATUS: PASS

Live deployment

• Snowdata catalog: deployed
• SnowSure + mcp.snowdata.ai catalogs: reference manifests (deployment in progress)

Update: SnowSure production deploy is verified.

• https://www.snowsure.ai/.well-known/ai-catalog.json → 200, CORS-open, 3 entries
• https://www.snowsure.ai/news/ard-catalog → live announcement

Happy to iterate on the reference manifests. The live catalog matches conformance/examples/snowsure-ai-catalog.json except for any trust-manifest signing we add next.

Hi — this is ready for review when you have a moment.

Live manifests (all 200, CORS-open):

https://www.snowsure.ai/.well-known/ai-catalog.json
https://www.snowdata.ai/.well-known/ai-catalog.json
https://mcp.snowdata.ai/.well-known/ai-catalog.json
Conformance: ./conformance/bin/conformance-test manifest conformance/examples/snowsure-ai-catalog.json → PASS

Also shipped since opening:

Ed25519 trust manifests + did:web:www.snowsure.ai DID document
DNS TXT: _catalog._agents.snowsure.ai → catalog URL
MCP entry uses application/mcp-server-card+json pointing at /.well-known/mcp/server-card.json
Happy to adjust the example manifests if anything should differ from the live files. Thanks!

We made some change to the resources identifier format (Please check 8fff974) . Can you fix the conformance test error?

[mikeslone]

Fixed — thanks for the heads-up on the URN change. Refreshed all three bundled examples (snowdata-ai-catalog.json, snowsure-ai-catalog.json, mcp-snowdata-ai-catalog.json) to the new urn:air: namespace in 711a107, regenerated from the live signed catalogs. All three pass the repo's conformance/ CLI (bin/conformance-test manifest <file>) with 0 critical errors. Ready for a CI re-run / merge whenever you get a chance — happy to adjust anything else.
