Linked.Archi UAF Metamodel Definition
Metamodel manifest for the Unified Architecture Framework (UAF) 1.2. Ties together the UAF entity ontology, SHACL shapes, SKOS taxonomy, viewpoint definitions, and alignment axioms into a single discoverable resource. UAF supersedes DoDAF, MODAF, and NAF, providing a unified framework that organizes architectural data across 10 viewpoints and 11 aspects. This is not an official OMG document.

Unified Architecture Framework (UAF)
The Unified Architecture Framework (UAF), an OMG standard (formal/2025-10-01 through formal/2025-10-07). UAF provides a unified architecture framework superseding DoDAF, MODAF, and NAF. It organizes architectural data across 10 viewpoints (Architecture Management, Strategic, Operational, Services, Personnel, Resources, Security, Projects, Standards, Actual Resources) and 11 aspects (Motivation, Taxonomy, Structure, Connectivity, Processes, States, Sequences, Information, Constraints, Roadmap, Traceability). UAF defines approximately 288 metaclasses organized into domains and supports capability-based planning, service-oriented architecture, and enterprise-wide architecture governance.
