-    description: |
-      Child types in a classification hierarchy (hyponyms/narrower concepts).
-      
-      **Temporal Semantics** (RiC-O Pattern):
-      The "hasOrHad" naming follows RiC-O convention indicating this relationship
-      may be historical - a type's children may change if hierarchy is reorganized.
-      
-      **Ontological Alignment**:
-      - **Primary** (`slot_uri`): `hc:hasOrHadHyponym` - Heritage Custodian ObjectProperty
-        for class-valued child types
-      - **Exact**: `skos:narrower` - SKOS ObjectProperty for subordinate concepts
-      - **Related**: `rdfs:subClassOf` (inverse) - RDF Schema superclass relationship
-      
-      **Usage**:
-      For Type classes, this links a more general type to its child types.
-      Example: "Climate-Controlled Storage" has narrower "Cold Storage", "Art Storage"
-      
-      **Cardinality**:
-      Multivalued - a parent type may have multiple child types.
-      
-      **Transitivity**:
-      skos:narrower is transitive - if A narrower B, and B narrower C, then A narrower C.
-      Use skos:narrowerTransitive explicitly if transitive closure is needed.
-      
-      **Note**: slot_uri changed from skos:narrower to hc:hasOrHadHyponym (2026-01-16)
-      to allow consistent class-valued ranges when classes override. skos:narrower
-      moved to exact_mappings (it is already an ObjectProperty in SKOS).
-      
-      **Range**: `uriorcurie` (2026-01-16) - Allows both URIs and CURIE references.
-
