Linked.Archi UAF Ontology: Description back to ToC

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.
