XML Schemas. An example of this collection of information is data associated with an arrest. The data to be exchanged includes not only descriptive and personal identification data regarding the individual arrested (i.e., the person component described above) but also information about the person's alleged offense, the location of the offense, the arresting officer, etc. The IEP represents a set of data that is actually transmitted between agencies for a specific business purpose (e.g., initiating a charging document by the local prosecutor). It includes the actual XML instance that delivers the payload or information. Additional information regarding this specific exchange can be further documented in the form of an information exchange package documentation (IEPD), which also contains data describing the structure, content, and other artifacts of the information exchange. An IEPD supports a specific set of business requirements in an operational setting. NIEM Core. Data components within an information exchange that are universally shared and understood among all (or almost all) domains are identified as universal components (e.g., person, address, and organization). To become a universal component, consensus by all domains is needed on the semantics and structure of the component. The set of NIEM universal components is stable (once established) and relatively small. Domains. For purposes of NIEM, a domain refers to a business enterprise broadly reflecting the agencies, units of government, operational functions, services, and information systems which are organized or affiliated to meet common objectives. NIEM domains are organized to facilitate governance, and each has some measure of persistency. Each domain traditionally includes a cohesive group of data stewards who are subject matter experts (SMEs), have some level of authority within the domains they represent, and participate in the processes related to harmonizing conflicts and resolving data component ambiguities. Communities of Interest. Communities of interest (COIs) are collaborative groups of users who exchange information in pursuit of shared goals, interests, missions, or business processes and who therefore must have a shared vocabulary for the information they exchange. COIs reuse data components and artifacts found in NIEM to document their information exchanges. One or more COIs can coordinate to develop new domain content as they identify gaps in the data components needed for documenting information exchanges. NIEM Conformance. There are NIEM conformance rules that serve as guidelines for agencies utilizing NIEM to implement their information sharing exchanges. Grantees developing inter-agency XML-based exchanges must comply with the special condition
