A structured, consistent framework for representing organisational architecture across strategic, operational, and supporting dimensions. Your semantic foundation.
The Orthogramic Metamodel provides the foundation for parsing, classifying, and synthesising business documentation into actionable insight. It serves as a universal grammar that enables consistent interpretation of enterprise architecture across any organisation.
Built on a schema-first approach using publicly available JSON Schemas, the metamodel enables automation, validation, and seamless integration into digital tools and platforms. Every domain is defined through attributes, elements, relationships, and interdependencies.
Cross-domain relationships provide structured links between entities—Customers to Capabilities, Policies to Services—allowing traceability, impact analysis, and improved alignment across the enterprise.
24+ interconnected domains
The metamodel is composed of three complementary sections that together provide comprehensive coverage of enterprise architecture.
The core concepts of business architecture. Each domain corresponds to a critical area of organisational structure or behaviour—Capabilities, Strategies, Stakeholders, Information, and more. These are the primary building blocks for interpreting business documentation and synthesising a holistic view of the enterprise.
Cross-cutting constructs that enrich and support the core domains. Extensions provide Tags, Comments, and Relationships that enhance usability, traceability, and governance. While domains model the "what" of the organisation, extensions support the "how"—how content is organised, linked, and governed.
A goal-setting and measurement framework to assess how well each business domain is documented and understood. These extensions support maturity modelling, strategic prioritisation, and alignment tracking by capturing expected coverage levels and comparing them to actual performance.
Domains are clustered into logical groupings based on their functions and relationships, providing comprehensive coverage of enterprise architecture.
The metamodel provides capabilities designed for real-world enterprise architecture challenges.
