ISO/IEC 19540-1:2022

Overview

ISO/IEC 19540-1:2022 specifies the UAF Domain Metamodel (DMM) - the conceptual foundation of the Object Management Group Unified Architecture Framework (OMG UAF). Part 1 (DMM) is a normative specification that defines the core concepts, relationships and viewpoints used across UAF. The DMM is intended as the authoritative metamodel for any UAF implementation (including non‑UML/SysML implementations). The broader ISO/IEC 19540 series also includes a UML/SysML profile (UAFP) and two informative annexes for traceability and example models.

Key Topics

• Domain Metamodel (DMM): formal definitions of domain elements, their types and relationships that form the basis of UAF modelling.
• Viewpoints and Views: structured view specifications covering domains such as Strategic, Operational, Services, Personnel, Resources, Security, Projects, Standards, Actual Resources, Dictionary, Summary & Overview, Requirements, Information, Parameters.
• UAF Grid & Domain Interrelationships: organization of model kinds and how domains relate across the architecture.
• Traceability: mechanisms and mappings (described further in informative annexes) that connect strategy through operations to implementation.
• Conformance and Language Architecture: rules for adopting the DMM and notes on changes where UAF adapts OMG specifications.
• Supporting artifacts: symbols, terms and definitions, diagrams and metamodel element catalogs to support consistent modelling.

Applications

ISO/IEC 19540-1:2022 is used to create consistent, interoperable architecture models and to drive model‑based engineering across organizations. Typical practical uses include:

• Enterprise and systems architecture alignment from strategy to implementation
• Tool vendor implementations of UAF (model repositories, model transformations)
• Model-driven engineering and automated analysis (traceability, impact analysis, roadmaps)
• Cross-framework mapping and integration of architecture artifacts
• Defence, aerospace, government and large enterprises needing rigorous architecture governance

Who uses it: enterprise architects, systems engineers, architecture tool developers, programme managers, integrators and compliance officers.

Related Standards

• UAF Profile (UAFP) - UML/SysML implementation of the UAF DMM (referenced as dtc/19-06-15)
• UAF Traceability (Annex A) - mappings between UAF and contributing frameworks (dtc/19-06-17)
• UAF Example Model (Annex B) - illustrative usage examples (dtc/19-06-18)
• Broader references: OMG UML/SysML standards when implementing the UAF Profile

This standard is essential for organizations adopting OMG UAF to ensure a common metamodel, consistent viewpoints and reliable traceability across architecture artifacts.
