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 / knowledge-plane
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.
What this means in practice
Distinguishing the knowledge plane from the model plane is a governance prerequisite because the two have different change cadences, data-residency requirements, and deletion obligations.
Synonyms
retrieval plane , AI knowledge layer

- 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.
- Vector store — A governed index of embeddings — numeric vector representations of text, image, or multimodal content — that supports similarity search used by retrieval-augmented generation.
- Embedding model — A model that maps text, images, or multimodal content to dense vector representations used for retrieval, clustering, and similarity search.
