National Information Exchange Model
"NIEM connects communities of people who share a common need to exchange information in order to advance their mission." (niem.gov)
Community-driven, government-wide, standards-based approach to exchanging information.
On-demand Common Information Exchange between Government Jurisdictions and Industry Partners.
The Enterprise Architect platform comprehensively supports the National Information Exchange Model (NIEM), which provides a common framework used to define how information can be shared between systems, government agencies and organizations.
NIEM originated from the need for automated, standards derived messaging of critical information sharing between government agencies, while ensuring security
and confidentiality integrity.
The importance of having critical
and accurate information quickly
at a crucial time ensures that more accurate and timely decisions are being made. This results in dramatic benefits realized in areas of public safety, emergency management and national security.
Benefits of NIEM:
The benefit to existing systems is that they can be retained without major change and by enabling interoperability, the cost of exchange for communities using NIEM, is lower.
The overall benefit is faster access to accurate information and better outcomes from improved decision making. The value of information-sharing is increased as more organizations actively participate and collaborate.
Offering the most up-to-date compliance of version 3.0 of the NIEM standard, Sparx Systems has developed a fully integrated information exchange environment with UML 2.5 at its core.
Enterprise Architect supports and implements the NIEM 3 UML profile based on the OMG NIEM-UML 1.1 Specification.
The NIEM Process:
Using Enterprise Architect's NIEM capability, UML-based Information Exchange Package Documentation (IEPD) models can be generated via the built-in pre-formatted model patterns, containing base exchange files, static artifacts, metadata and catalog files as a starting point for further customization.
Alternatively, by using the Schema Composer within Enterprise Architect, end users can generate their own NIEM subset namespaces, automatically detecting inter-dependencies, with the resulting subset schema building the IEPD.
Information Exchange Package Documentation (IEPD)
An IEPD defines recurring messages in XML to satisfy information exchange of business requirements.
The IEPD development lifecycle contains six distinct steps for the development of artifacts,
adopting an interactive methodology, until the desired conditions meet the IEPD requirements.
An IEPD is a combination of both business and technical information for an information exchange:
IEPD's consist of XML schema documents
that define instance XML documents that tag
and transport the information to be exchanged.
IEPD's provide documentation such as
business scenarios and other aspects of
the business requirements for the exchange.
NIEM Diagram Toolbox Pages:
By using the NIEM Toolbox pages, the Platform Independent Model (PIM), Platform Specific Model (PSM) and Model Package Description (MPD) diagrams can be created.
Enterprise Architect also supports the importation of the NIEM Reference Schema as well as generation of a NIEM Schema from the end user's customized model.
