attestationsthat

Attestationsthat is a term used in discussions of data provenance and attestations to describe a statement that is explicitly supported by an attestation from a trusted source. It functions as a marker that the claim preceding it has been verified or endorsed.

Although not widely standardized, the term appears in theoretical works and pilot implementations exploring how to bind assertions to verifiable attestations, rather than relying on the assertion alone.

In practice, an attestationsthat appears in documents, records, or digital contracts to indicate that the contained assertion has been validated by an authority. It is often used in governance, compliance reporting, supply-chain traceability, and electronic records management.

Implementation commonly includes metadata such as the issuer identity, timestamp, method of attestation, and cryptographic proof (for example a digital signature or a hash linked to a public key). The attestation can be stored alongside the claim or in a linked provenance graph to support auditing.

Example: a data package includes an attestationsthat the data was collected with informed consent, with the attestation issued by the data-collection sponsor.

Challenges include a lack of standard semantics, interoperability across systems, and legal recognition of attestationsthat tags. Ensuring verifier trust, revocation, and privacy considerations are active areas of research.
