CIEF differs primarily from current Information Exchange Data Models (IEDM) in its focus on the mission context and corresponding filtering of the Valued Information at the Right Time (VIRT). Beyond the basic architecture, CIEF offers a framework that can scale beyond simple exchange models to include all information and data sources of the Global Information Grid (GIG).
