AIM enables policy-as-metadata . An access control rule can be embedded: "allowed_uses": ["non-commercial-research", "model-training"] . A data processing engine must evaluate these rules before computation, enabling fine-grained, persistent usage control. An access control rule can be embedded: "allowed_uses":
