====== Policy Evaluation Role ======

===== Discussion =====

The Policy Evaluation Role identifies responsibility for evaluating policy constraints governing access, disclosure, safeguarding, release, redaction, transformation, marking, obligations, or the controlled movement of FX information.

This role includes receiving policy decision requests, evaluating requested release context, assessing policy constraints, producing FX Policy Decisions, and recording policy evaluation rationale and provenance.

The Policy Evaluation Role participates primarily in the FX Logical [[dido:99_annexes:annex-b-terms-and-definitions:p:policy_and_release_plane|Policy and Release Plane]]. It also supports the FX Logical [[dido:99_annexes:annex-b-terms-and-definitions:a:audit_and_provenance_plane|Audit and Provenance Plane]] when policy decisions preserve policy version, input references, decision rationale, obligations, and [[dido:99_annexes:annex-b-terms-and-definitions:e:evidence|evidence]] expectations.
