claim_subject

Term URI: https://w3id.org/agent-evidence/vocab/v1/claim_subject

Section: posture_and_coverage. Criticality: critical.

The class of subject a claim is about. A claim at one class is never evidence at another: a result about a tool's definition says nothing about an agent that called it, and a result about an agent's run says nothing about the organization that operates it. A consumer MUST NOT satisfy a requirement stated at one class with a claim carrying another, and a claim with no declared class MUST be treated as not satisfying any class-specific requirement.
