semantic match

Lexicons whose schemas describe something close to this one. Check them before publishing a new one that overlaps.

  • An outside fact entering the workspace: a fetched page, a file, a command's output, or something the operator said. Claims cite observations rather than each other. Never edited: a changed source gets a new observation that supersedes this one.

  • An explicit, typed link between two observations. Enables protocol-visible claim relationships.

  • A LinkedClaim record per the DIF Labs LinkedClaims specification (https://identity.foundation/labs-linkedclaims/). Claims are immutable, signed assertions about any URI-addressable subject. Each claim has a persistent URI (claimUri) so other claims can reference it as their subject, enabling a cross-system web of trust. LinkedClaims flow on ATProto but are not exclusive to it — the claimUri may point to any system where the claim originated.
