Ontology
A schema layer that defines entity types and the meaning of relationships in a knowledge graph, ensuring structural and semantic consistency as the graph scales and enabling agents to perform traversal-based reasoning along explicit relationships.

Enterprise knowledge ontologies are typically represented in standard formats such as RDF/OWL and support SPARQL queries.
AgentOnto is an ontology-guided LLM agent framework that improves the reliability and adaptability of enterprise data analysis by constructing, using and updating an enterprise knowledge ontology.
New relationship names have to "earn their place": only after the same name appears in three different notes is it automatically promoted into the ontology.
In the author's ontology design, entity identity is strictly determined by type and name with no fuzzy matching: if two notes both say Northwind they merge into one node, while writing Northwind Trading produces a second node until someone maps it manually.
The current version of IQ MCP Server does not yet support ontologies and data agents; they each have their own independent MCP endpoints.
The ontology describes what exists and what can happen in a domain; the gate checks whether this instance is permitted, and the gate must be independent of the ontology.
Ontology originates from philosophy; in computer and knowledge engineering it refers to an explicit, formal specification of the concepts, attributes, and their relationships within a domain, with common forms including classes, properties, instances, and relationship constraints.
Semantic models answer aggregation-type questions (such as rankings and counts), while ontologies answer relationship-type questions (such as multi-hop relationship queries)
For simple document Q&A, vector retrieval with reliable citations may already be sufficient; building ontologies and knowledge graphs is more likely to pay off only when problems involve cross-system entities, multiple relationships, historical states, compliance rules, and accountability tracing.
Ontologies use standard languages such as OWL or RDFS to define types, properties, and constraints, serving as the schema layer of the knowledge graph.

Knowledge graphs store knowledge in the form of 'entity-relation-entity' triples, and can explicitly express entity relationships compared to vector databases.
