AI Core Reference Ontology

Public descriptive ontology for AI audit interoperability. Descriptive. Non-normative. Not a regulatory authority. AI Core is not an implementation tool and does not execute audits.

Separation of Domains

The Audit Domain must remain logically separated from the Source Domain. Observation does not imply modification.

Process Overview

An Audit Plan is executed by a Runner inside the Audit Domain. The Runner observes the Audited Object and produces Evidence. Evidence is structured into an Evidence Manifest and stored in the Evidence Layer.
