What kind of information can be exchanged using the National Information Exchange Model (NIEM)?
Information that is exchanged between agencies can be broken down into individual components—for example, information about people, places, material things, and events. Data components within an information exchange commonly shared and understood among all domains are identified as universal components (e.g., person, address, and organization), while components used in exchanges between multiple domains, but not universally shared, are identified
as common components (e.g., offense, sentence, and disposition). Components managed by a specific COI (e.g., appellate case decision and arrest agency) are considered domain specific.
