+#

+# - Rule 39: Supports RiC-O temporal naming convention
+# - Rule 0b: Part of Type/Types naming convention

+      Abstract base class for all type classification classes in the heritage ontology.
+      
+      **Purpose**:
+      Enables the `any_of` pattern in generic slots (e.g., `has_or_had_type`) to accept
+      both string literals and class instances. This resolves OWL "Ambiguous type" 
+      warnings that occur when slots have `range: string` but classes override to 
+      class types via `slot_usage`.
+      
+      **Inheritance**:
+      All concrete Type classes (AddressType, BackupType, ConditionType, etc.) 
+      should inherit from this class using `is_a: TypeClass`.
+      
+      **Ontological Alignment**:
+      - class_uri: `skos:Concept` - Type classes represent controlled vocabulary concepts
+      
+      **See Also**:
+      - Rule 0b: LinkML Type/Types File Naming Convention
+      - Rule 53: No bespoke slots - generic/reusable patterns
+    
+    annotations:
+      specificity_score: 0.10
+      specificity_rationale: |
+        Very low specificity - this is a foundational abstract class used as the
+        base for all type classification classes across the entire ontology.
+      owl_fix_date: "2026-01-16"
+      owl_fix_purpose: |
+        Created to resolve 18 "Ambiguous type" warnings from gen-owl.
+        Serves as range in any_of patterns for generic slots.
