The model in numbers
Four architecture planes
The cognition plane as a cross-cutting architectural plane alongside the data, control and management planes — as per the peer-reviewed EA4AI paper (Springer LNBIP).
Cognition Plane
Where AI agents reason, interpret and decide — under explicit mandate. With agents, mandates, reasoning boundaries, orchestration, grounding and explainability.
Control Plane
Where governance is enforced at runtime. Identity & access management, authorization, policy-as-code, audit trails and API gateways.
Data Plane
Where knowledge and data are managed. Vector databases, knowledge graphs, feature stores, RAG indices and document storage.
Management Plane
Where AI systems are operated. Configuration, deployment, monitoring & observability, model registry, lifecycle and resourcing.

The full context
This architecture model is based on the AI-BOK book, which elaborates all principles, roles, patterns and rationale in detail. Find the model valuable for yourself or your organisation? A book licence gives you the full context and supports further development.
