Orthogramic Metamodel – JSON-LD Ontology Summary

This document defines the structured, schema-based representation of business architecture domains used by Orthogramic, with mappings designed for semantic interoperability with external frameworks including BIAN, TOGAF, and http://schema.org .

Overview

• Format: JSON-LD

• Purpose: Enable semantic APIs, business architecture alignment, and integration with banking and enterprise models

• Compatibility: BIAN, http://schema.org , FOAF, ArchiMate

Domains

Capabilities

Defines what an organisation is able to do, independent of how it is done. Serves as the bridge between strategy and operations. Mapped to: bian:BusinessCapability

Services

Represents business or technical offerings delivered to customers, internal stakeholders, or partner systems. Mapped to: bian:ServiceDomain

Stakeholders

Describes people, groups, or institutions that influence or are influenced by the organisation. Mapped to: foaf:Agent

Value Streams

Models the stages of value creation — showing how value flows from initiation to outcome. Mapped to: bian:ValueStream

Initiatives

Captures programs, projects, or major efforts that enable change and implement strategy. Mapped to: bian:InitiativeProgram

Policy

Describes regulatory obligations, internal controls, and formal decision-making rules. Mapped to: bian:PolicyRule

Information

Captures data entities, structures, and custodianship aligned with business capabilities and governance. Mapped to: schema:Dataset (complemented by BIAN data specification constructs)

Performance

Measures outcomes and progress via KPIs and metrics linked to strategic objectives. Mapped to: bian:PerformanceAssessment, bian:PerformanceIndicator

Strategic Response Model (SRM)

Links Triggers, Rationales, and Strategic Responses across domains to support dynamic alignment and decision-making. Mapped to:

• bian:TriggerEvent

• bian:RationaleForChange

• bian:ResponseStrategy

Use in Semantic APIs

This metamodel enables:

• Federated querying of architecture data

• Business-aligned API responses

• Linked data representations of capability maps, governance models, and change strategies

• Interoperability between banking systems (via BIAN) and enterprise architecture platforms
