What are the National Information Exchange Model (NIEM) components?

When working with the National Information Exchange Model (NIEM), information that is exchanged is broken down into the following components:

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.
