Ontology
A foundational concept in knowledge representation and semantic modeling, originating in philosophy and later adopted in computer science within the Semantic Web framework. By defining four element types—classes, instances, properties, and relations—ontologies provide machines with an interpretable domain knowledge structure that natively supports logical reasoning.

FDE implementation practices can be broadly divided into two technical routes: Palantir's ontology-driven approach and AI Agent's scenario-driven approach.
The word "ontology" originates from philosophy and refers to the basic assumptions and classification systems concerning what exists and what is real.
Designed artifacts have ontological significance: they shape and sometimes narrow what becomes possible or imaginable.
Ontology is a concept from the field of knowledge engineering, referring to a formal system of descriptions of entities, relationships, and rules within a given domain.
The term ontology originates from philosophy, referring to the study of being.
Semantic models are more like relational mapping tables (field A corresponds to metric B), whereas ontologies are more like knowledge graphs that explicitly encode inheritance relationships, mutual exclusion constraints, and temporal validity between concepts.
Data stack architecture is evolving from a 'data → BI → human' pipeline to a 'data → ontology → AI Agent → human' pipeline.
The combination of ontology and vector databases is forming a new technological paradigm: ontology graphs provide precise business constraints, while vector retrieval supplements long-tail contextual information.
The independent ontology query service path has a longer chain but enables stricter boundary control, making it especially suitable for high-accuracy scenarios such as finance and compliance.
Two technical paths for injecting ontologies into AI Agents: one is serialization followed by injection into the System Prompt or RAG context; the other is building an independent ontology query service for the Agent to actively call for semantic validation.
