What are NIEM Universal and Common Core components?
The NIEM data model includes two categories of reusable components (aka business objects)Core components and domain-specific components. The NIEM Core components (Core Namespace) are further classified as either Universal or Common. Core components that are commonly shared and understood among all NIEM domains are classified as universal components (e.g., person, address, organization). Core components used in exchanges between multiple domains, but not universally shared, are identified as common components. Components understood and managed by a specific community of interest are considered domain-specific. Domain-specific components can extend Core components and must conform to the NIEM Naming and Design Rules.
