The COMPEL Glossary Graph visualizes relationships between framework terminology, showing how concepts interconnect across domains, stages, and pillars. Term nodes cluster by pillar affiliation while cross-references reveal semantic dependencies — for example, how risk appetite connects to control effectiveness, model governance, and assurance requirements. This network representation helps practitioners navigate the framework vocabulary and understand that COMPEL terminology forms a coherent conceptual system rather than isolated definitions.
COMPEL Glossary / orchestration-plane
Orchestration plane
The layer of an AI system that coordinates prompts, retrievals, tool calls, safety filters, and routing between the user and one or more models.
What this means in practice
Distinct from the model plane because orchestration logic is the locus of most governance controls — policy enforcement, audit logging, and human-in-the-loop gates all live here.
Synonyms
orchestration layer , AI orchestration plane
See also
- AI reference architecture — A canonical layered model — client, orchestration, model, knowledge, observability planes — that every AI system maps onto.
- Knowledge plane — The layer of an AI system that stores and serves non-parametric knowledge to the model — through retrieval over vector stores, traditional indexes, and tool-based data access.
- Agent loop — The iterative pattern in which a model plans, calls tools, observes the results, and replans — continuing until a goal is met, an iteration budget is exhausted, or a human intervenes.
- Policy engine — A declarative rule engine that gates agent actions — via ABAC-style policies evaluating identity, resource, environment, and action attributes.
