NIST recently published NIST Internal Report (NISTIR) 8112, Attribute Metadata: A Proposed Schema for Evaluating Federated Attributes, which contains an attribute that can be used by relying parties to perform run-time evaluation of an individual’s ability to access protected resources. Attribute metadata also enables the possibility for data sharing permissions and limitations on individual data elements. There are other applications of attribute metadata, such as evaluation and execution of business logic in digital services or associated with devices or non-person entities.
