  "summary": "ArchiMate is a graphical modeling language for enterprise architecture: standardized notation, layers (business, application, technology), and viewpoints designed so human architects can draw and read consistent diagrams. OCOM is not a diagramming language; it defines its own notation at the Language tier, including a graphical form, and is a specification for describing operating reality; a model built with it is the governed record, maintained as data that humans, software systems, and AI agents read the same way. ArchiMate draws the architecture for people; OCOM governs the record of what is operationally true for people, systems, and agents.",

  "coverageNote": "Covered: the model defines the concept explicitly. Partial: the concept appears indirectly or by convention. Out of scope: the model does not set out to describe it; a boundary, not a deficiency. Three OCOM cells read Partial rather than Covered because the specification's own register records the gap: Evidence (AO-021), Governance (AO-023) and AI retrieval (AO-048). Workflow and Event are defined normatively at the Models tier without a Core Vocabulary term record."
