What are the operational processes involved in the National Information Exchange Model (NIEM)?
NIEM includes a set of operational processes and procedures, standards,documentation, tools, training, and technical assistance which support each step in the NIEM IEPD life cycle.
NIEM documentation and standards include a data dictionary, data model, andIEPDs. The data dictionary is a well‑defined vocabulary of data names and structures. The data model is the body of concepts and rules that underlie the structure of the data dictionary, including data components arranged by domain, the type of data being represented (date, integer, Boolean, string, etc.), and a semantically precise, context‑rich definition of each component. Together the data dictionary and model become a database, from which XML schemas are generated. These schemas contain the data components that are reused to construct the IEPDs.
