NIEM - National Information Exchange Model Viewer
NIEM is a common vocabulary that enables efficient information exchange across diverse public and private organizations.
NIEM is an outgrowth of the United States Department of Justice's Global Justice XML Data Model (GJXDM) project. NIEM is now being expanded to include other federal and state agencies such as the Office of the Director of National Intelligence, United States Department of Defense, Federal Bureau of Investigation, Texas, Florida, New York, Pennsylvania, and others.
Data Dictionary Search
Grid-ML generates the NIEM XML Data Dictionary directly from the schema and allows you search and view all data and type definitions. This is much faster and efficient than dealing with the raw NIEM XML data dictionary spreadsheet.
Narrow down your search by selecting the schema subset you are interested in, based on the Information Exchange Document (IEP) you are working with.
Versions and Namespaces
Grid-ML supports all NIEM Model versions. It comes pre-loaded with versions 1.0, 2.1, 3.2, and 4.2; and allows you to load alpha and beta versions as well.
Search across multiple versions at once, see how a data point is represented in different versions of the standard, and compare that with your own proprietary schemas.
Search across multiple namespaces, such as your target NIEM Domain, NIEM core, and external schemas. Quickly find what you are looking for without having to deal with dozens of source files.
XPath and JSON Path
NIEM Extensions Points
Grid-ML automatically resolves the NIEM Extension Points and places the extension elements inline where they belong. That allows data analysts to easily understand and visualize all the data structures, without having to deal with the underlying technical concepts.

- CBRN - Chemical, Biological, Radiological, and Nuclear Domain
