+  GrantRange:
+    class_uri: crm:E54_Dimension
+    description: |
+      Structured representation of a funding or grant amount range.
+      
+      **PURPOSE**:
+      Replaces string-based grant ranges like "€100K-€500K" with structured data
+      enabling comparison, filtering, and currency-aware analytics.
+      
+      **STRUCTURE** (per slot_fixes.yaml):
+      - `minimal_of_minimal` → Quantity (branch 1): Lower bound with amount and currency
+      - `maximal_of_maximal` → Quantity (branch 2): Upper bound with amount and currency
+      
+      **CIDOC-CRM Alignment**:
+      Maps to E54_Dimension which represents quantifiable properties,
+      using P90a/P90b for lower/upper value limits.
+      
+      **USE CASES**:
+      - Heritage grant programs (Mondriaan Fund, EU Creative Europe)
+      - Digitization funding ranges
+      - Conservation project budgets
+      - Research grant parameters
+      
+      **EXAMPLE** - Creative Europe Grant:
+      ```yaml
+      has_or_had_range:
+        - minimal_of_minimal:
+            quantity_value: 60000
+            has_or_had_measurement_unit:
+              unit_label: "EUR"
+          maximal_of_maximal:
+            quantity_value: 200000
+            has_or_had_measurement_unit:
+              unit_label: "EUR"
+          range_description: "Small-scale cooperation projects"

+        description: Human-readable description of what this range represents.

+          ISO 4217 currency code for the range (convenience field).
+          Should match currency in minimal_of_minimal/maximal_of_maximal Quantities.

+          - value: "EUR"
+          - value: "USD"
+          - value: "GBP"
+      
+      range_notes:
+        range: string
+        description: Additional notes about range applicability or conditions.
+        examples:
+          - value: "Maximum 80% of total project budget"
+          - value: "Co-financing required"
