Attribute metadata

NIST Internal Report (NISTIR) 8112: Attribute Metadata defines a schema for metadata that describe a subject’s attributes; it is intended to give relying parties (RPs) greater insight into the methods attributes are determined to assist in making risk-based business decisions. As a result, RPs can examine this metadata and determine if they have the confidence they need in the attribute value before making an authorization decision. This NISTIR is being treated like an “implementers’ draft” – an approach used that focuses on real-world implementation results and lessons-learned before the document can become finalized.
