- The AT protocol uses at:// URIs to point to hyperlinked JSON data across servers.
- URIs in the AT protocol place the user as the authority, not the host, making data ownership clear.
- Resolving an at:// URI involves three steps: handle to identity (DID), identity to hosting, and hosting to JSON.
- Handles (like ruuuuu.de) can be resolved to immutable DIDs (like did:web:iam.ruuuuu.de) via DNS or HTTPS.
- DID Documents act as 'internet passports,' linking identities to hosting and verifying data integrity.
- Two DID methods are supported: did:web (tied to domain control) and did:plc (managed by a public ledger).
- The serviceEndpoint in a DID Document points to the server hosting the JSON data.
- AT protocol abstracts HTTP, DNS, and JSON to make data portable and user-owned.
