description: "A quantified value with an optional unit of measurement and type.\n**QUDT ALIGNMENT**:\nMaps to `qudt:Quantity` - \"A quantitative value expressed as a number and a unit of measurement.\"\n**TYPES OF QUANTITIES**:\n| Type | Description | Example | |------|-------------|---------| | STAFF_COUNT | Number of employees | 42 employees | | COLLECTION_SIZE | Number of items | 1.2 million objects | | VISITOR_COUNT | Annual visitors | 2.5 million/year | | BUDGET_AMOUNT | Financial value | \u20AC15 million | | AREA | Physical space | 10,000 m\xB2 | | DURATION | Time period | 6 months |\n**USE CASES**:\n1. **Staff Metrics**: Branch staff count, department size, FTE equivalents 2. **Collection Metrics**: Object counts, archive linear meters, digital items 3. **Visitor Metrics**: Annual attendance, daily capacity, peak visitors 4. **Financial Metrics**: Budget, revenue, acquisition costs 5. **Physical Metrics**: Floor area, gallery space, storage capacity\n**WHY NOT JUST USE INTEGER?**\n\
|
|
Simple integer fields like `branch_staff_count: 3` lose important context: - What's the unit? (FTE? headcount? contractors included?) - When was this measured? (provenance) - Is this exact or estimated? - What type of quantity is this?\nThe Quantity class captures this richness while remaining simple for basic use.\n**EXAMPLE**:\n```yaml Quantity:\n quantity_id: https://nde.nl/ontology/hc/quantity/nha-zaanstreek-staff-2025\n quantity_value: 3\n quantity_type: STAFF_COUNT\n has_or_had_measurement_unit:\n has_or_had_type: VISITOR\n has_or_had_symbol: \"visitors\"\n temporal_extent:\n begin_of_the_begin: \"2024-01-01T00:00:00Z\"\n end_of_the_end: \"2024-12-31T23:59:59Z\"\n has_or_had_description: Staff assigned to Zaanstreek-Waterland branch\n```\n**RULE 53 COMPLIANT**: Updated with link_branch slots (has_or_had_measurement_unit, temporal_extent, has_or_had_methodology) per slot_fixes.yaml revision for visitor_count, view_count, unique_object_count, and unique_face_count\

comments:
|
|
- Quantity models quantified values with units and provenance
|
|
- Replaces simple integer fields with richer structured data
|
|
- Uses QUDT Quantity as primary ontology mapping
|
|
- Supports various quantity types (staff, collection, visitor, budget)
