Are Service Specification similar to NIEM IEPDs?

Service Specifications are similar to National Information Exchange Model ([NIEM]) Information Exchange Package Documentation (IEPD), commonly used within the justice community. They document the conceptual, logical, and physical models of a service in the same way NIEM IEPDs document the conceptual, logical, and physical models of a data exchange. Also, as with IEPDs, Service Specifications are a composite set of documentation, models, policies, contracts, and schemas that together provide a clear view of the service capabilities and business and technical requirements. While both Service Specifications and NIEM IEPDs are sets of artifacts which enable justice agencies to effectively share information and are of similar construction, they are not equivalent concepts. From a GRA perspective, NIEM IEPDs are used to describe the information model of a service and, as such, become a part of the Service Specification.
