Introduction

The Orthogramic Metamodel is designed to facilitate semantic interoperability across diverse enterprise architecture frameworks. To support this objective, we have developed detailed JSON-LD context mappings for two prominent frameworks:

  • BIAN (Banking Industry Architecture Network) – a service-oriented architecture model tailored for the banking and financial services sector

  • SAP Enterprise Architecture Framework – SAP’s structured approach to modelling enterprise architecture in SAP-centric environments

These mappings enable seamless integration between the Orthogramic Metamodel and these established frameworks, promoting consistency and reuse in enterprise modelling, data transformation, and knowledge graph construction.

Additional context mappings will be added over time as further interoperability requirements emerge, including support for standards such as ArchiMate, TOGAF, and others used across industry and government.

Adjacent metamodels

1. BIAN (Banking Industry Architecture Network)

...

  • Focus: Military systems architecture and interoperability

  • Key concepts: Capability, Performer, Activity, Resource Flow, Standards

  • Adjacency: Orthogramic’s Capabilities, Stakeholders, Initiatives, and Value Streams map well conceptually

  • Comparison: DoDAF is highly formal, based on mission assurance and traceability; Orthogramic is lighter, more flexible

  • Used by: Defence agencies, system-of-systems architects, NATO/coalition partners
