3.1 A3I Library and Dissemination System Description
A3I Libraries are composed of three types: Product, Command, and National. The three types are differentiated by content, storage size, performance, and responsibility for operations and management. They are alike in that each type may contain digital imagery or digital imagery products from all sources including tactical, theater, national, civil, and commercial collection systems. All libraries share common digital imagery standards.
Image Product Libraries (IPLs) contain shared, restricted, or both types of data. IPLs shall be based upon the existing Demand Driven Direct Digital Dissemination (5D) and the Imagery Product Archive (IPA) capabilities, scaled for size and performance, and some shall be portable. IPLs support various levels of commands, Common Imagery Ground/Surface System (CIGSS) sites, and other organizations outside the command structure of the services, that require the use of libraries.
3.2 A3I Library and Dissemination System Requirements
