Core Linked.Archi Ontology for Enterprise and IT Architecture modeling.

Base Ontology EA modeling.

Base SHACL shapes for the Linked.Archi core ontology. These shapes apply to all metamodels that extend the core. Metamodel-specific shapes (e.g., ArchiMate, C4, Backstage) import this file and add type-specific constraints.

Framework-agnostic architecture viewpoints derived from ISO/IEC/IEEE 42010 and common architecture practice. These are universal viewpoints that any modeling language can use — ArchiMate, TOGAF, C4, Backstage, or custom metamodels can specialize or reference them.

Framework-agnostic deliverable templates that define the content structure of common architecture documents. Each template specifies which viewpoints are required — the actual views are created when someone instantiates the template into a concrete deliverable (arch:Model). These templates reference core viewpoints. Framework-specific templates (e.g., TOGAF Architecture Definition Document) should be defined in the respective framework's file, referencing framework-specific viewpoints.

Extension ontology for modeling architecture decisions, the issues that trigger them, candidate options, influencing forces (requirements, constraints, trends), and the rationale linking forces to chosen options. Use this extension when you need to capture decision records, trace forces to options, or integrate with ADD-style iterative decision processes.

Extension ontology for modeling architecture governance processes, activities, tasks, and their inputs and outputs within architecture models. This extension enables architects to capture process-oriented aspects of architecture work — governance workflows, lifecycle activities, and the artifacts they consume and produce — as first-class elements in architecture models alongside structural and behavioral elements. Use this extension when you need to: * Model architecture governance processes and their decomposition * Capture process inputs (forces, models, information items) and outputs (decisions, deliverables, models) * Trace how architecture activities relate to decisions and deliverables * Integrate process views into architecture descriptions The classes in this extension are practical model elements (subClassOf arch:Element) that can be used in architecture views and governed by metamodels, just like elements from the decisions or reference architecture extensions. The process concepts are aligned with ISO/IEC/IEEE 42020 (architecture governance), ISO/IEC/IEEE 12207 (software lifecycle), and ISO/IEC/IEEE 15288 (system lifecycle). For the normative standard definitions themselves, see the corresponding standard vocabularies under standards/.

Extension ontology for modeling reference architectures, reference models, architectural patterns, tactics, and building blocks (ABB/SBB). Use this extension to capture reusable architectural knowledge, classify patterns by type (module, integration, deployment), relate tactics to quality attributes, and trace how patterns and tactics interact.

Extension ontology providing a taxonomy of architectural tactics organized by quality attribute (availability, interoperability, modifiability, performance, security). Use this extension to classify concrete design techniques that architects employ to achieve specific quality-attribute responses, and to relate them to patterns and decisions.

Extension providing named quality-attribute individuals (beyond ISO 25010) for use in architecture decision evaluation, tactic mapping, and quality-attribute scenario modeling. Use this extension to reference resilience-oriented quality attributes such as Safety, Survivability, Longevity, and Adaptability that complement the ISO 25010 taxonomy.
