CALL NUMBER: deep_long_term_memory.kg_ontology DEFINITION: The schema layer of a knowledge_graph defining allowed kg_entity types (classes), allowed kg_predicate labels, and domain/range constraints on kg_relationships

Invoke this skill to understand kg_ontology down to its primitives. The RELATIVE ROOT below is the least-fixed-point closure of everything it bundles from — the full import cone, grouped by the lib each prim comes from. Projected from a prover-typed KB (MAP/SWI-Prolog consistency gate): every reference below resolves.

THE RELATIVE ROOT (the import cone, by lib)

from ?

• is_a (d2): A taxonomic relationship linking a kg_instance to its kg_class, establishing membership and enabling inheritance of class-defined properties and constraints.

from deep_long_term_memory

• kg_class (d1): A kg_entity type within the kg_ontology; groups instances that share structural or semantic properties
• kg_predicate (d1): The label or type of a kg_relationship; defines the semantics of how two kg_entities relate (e.g., is_a, part_of, owned_by, caused_by)
• kg_schema (d1): The structural blueprint specifying which kg_predicate labels are permitted between which kg_entity types; enforced by kg_ontology constraints

Projected from the llm memory and context engineering KB (438 concepts / 213 relations) — consistency-typed by MAP; the facet list after the colon IS the cross-lib dependency web.

(leaf — this is an actual skill.)
