"A national program supported by the Federal government, NIEM [National Information Exchange Model] connects communities of people who share a common need to exchange information in order to advance their missions. […] The NIEM vision is to be the best practice, by choice, for intergovernmental information exchange. Practitioners at all levels of government and industry will share accurate, complete, timely, and appropriately secured information to enable informed decision making for the greater good. NIEM will provide a common vocabulary to ensure consistency and understanding among domains that may not collaborate traditionally to simplify the process of information sharing between them."
