The NIEM model is a data model made up of a collection of properties and types defined within a set of namespaces, organized by governance authority. NIEM components can be leveraged as reusable building blocks in information exchanges, providing consistency and well-defined semantics that support interoperability among various exchange partners.
Significant changes to the NIEM model in version 6.0 from previous version 5.2 include:
Core and cross-domain harmonization
Updates to support the transition of NIEM to an OASIS Open Project, including namespace URI changes.
Updates to support upcoming [NIEM-NDR-v6.0] changes, including:
structures:uri attribute to relate
different roles of the same entity in a message together, replacing the
previous RoleOf construct.Updates related to new digital identity requirements led by the Emergency Management domain, including:
nc:IdentificationType and related augmentation
typesnc:LicenseType (new) to support other kinds of
licenses with NIEMj:DriverLicenseType and related typesnc:PassportType, which now extends
nc:IdentificationTypeem:PersonIDCardType, which has been refactored to
augment nc:IdentificationTypem:SeamanLicenseType, which can now be represented by
the new nc:LicenseTypem:MerchantMarinerDocumentType, which can now be
represented by the new nc:LicenseTypeCode set updates, including:
Synchronized the Justice domain version number with the rest of the model
Changes to version 6.0 are described in more detail in

Properties and types in NIEM are defined in namespaces, which are organized by governance or authoritative source:
NIEM Core is the collection of general-purpose content that does not belong to any one authoritative source. As such, this content is managed collaboratively by the NBAC, which includes representatives from the NIEM domain subcommittees.
NIEM domains are namespaces for communities of interest that have stood up their own formal governance bodies as NBAC subcommittees within NIEM.
While code sets can be defined in NIEM Core, domains, and other namespaces, code namespaces are almost exclusively comprised of code sets. Some NIEM code namespaces are actively managed by domain subcommittees or authoritative sources which work directly with NIEM. Other NIEM code namespaces are managed by the NBAC or domain subcommittees and reflect publicly available code sources, modified to conform to NIEM NDR rules.
Adapters are provided by the NDR as the mechanism to support non-conformant external standards in NIEM schemas and instances without triggering conformance violations. Like code sets, while adapters can be defined in other namespaces, adapter namespaces are for namespaces that exclusively define adapters for external standards.
Auxiliary namespaces define content representing communities of interest or standards. Unlike domains, they do not require formal governance bodies within NIEM.
External namespaces in NIEM are non-conformant external standards. These are provided for when the use of other standards defined outside of NIEM would provide greater interoperability than to create NIEM-conformant components representing those standards. Properties from external standards are wrapped by NIEM adapter types, which prevent NDR conformance rules from triggering errors on their use.
Utility namespaces in NIEM provide architectures support from the NDR and other NIEM technical specifications. They provide mechanisms to support such things as ids and references, linked data, IC-ISM and NTK security markup, dynamic code list support and code list support for codes defined in CSVs, Genericode, and other non-schema enumeration formats.
The architecture of the NIEM model is governed by the NDR, which provides:
general-purpose rules for naming, defining, and modeling components
special constructs and techniques to represent features including:
language-specific syntax rules
an RDF interpretation of the underlying data model
rules for extending the NIEM model to meet local requirements
Initially, NIEM has been limited to XML-based exchanges. NIEM is working to provide similar levels of support for JSON-LD, and mechanisms to support other languages as well.
Major versions of the NIEM Model correspond to major versions of the NDR. The architecture of the NIEM Model v6.0 is defined by [NIEM-NDR-v6.0].
This specification normatively defines NIEM Model Version 6.0 with a set of reference XML schemas.
The NIEM Naming and Design Rules [NIEM-NDR-v6.0] defines conformance targets, Schematron and text rules, and guidance for the conformant use of NIEM in messages and message specifications.
The NIEM Conformance Specification [NIEM-Conformance-v6.0] describes NIEM conformance.
