v1.2 draft uafmm: Kalin Maldzhanski Linked.Archi Modified: 2026-02-01 License

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.

The complete UAF 1.2 metamodel definition, aggregating the entity ontology, SHACL shapes, SKOS taxonomy, viewpoint definitions, and alignment axioms.

Based on Framework

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.

onto

Linked.Archi ontology aligned to the Unified Architecture Framework (UAF) version 1.2, 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 and 11 aspects, defining approximately 288 metaclasses across multiple domains. This ontology models the core entity types used across UAF viewpoints as OWL classes extending arch:Element, and the key relationships using the three-declaration pattern (unqualified predicate, qualified class, qualified property). This is not an official OMG document.

Architecture Viewpoints

viewpoints

UAF 1.2 viewpoints modeled as arch:Viewpoint individuals. UAF defines 10 viewpoints that organize architectural concerns. Each viewpoint specifies the concepts it includes, its purpose, and the concerns it frames. This is not an official OMG document.
