    class_uri: vcard:Address
    description: |
      Physical or postal address for heritage custodians and related entities.
      **ONTOLOGY ALIGNMENT**:
      This class aligns with multiple established address ontologies:
      | Ontology | Class | Notes |
      |----------|-------|-------|
      | **vCard** | `vcard:Address` | RFC6350 ADR property components |
      | **Schema.org** | `schema:PostalAddress` | Web semantics |
      | **LOCN** | `locn:Address` | EU Location Core Vocabulary |
      | **GLEIF** | `gleif_base:PhysicalAddress` | Legal entity addresses |
      **COMPONENT STRUCTURE**:
      An address consists of hierarchical components:
      ```
      Address
      ├── has_or_had_section (e.g., "1", "221B", "25-27")
      ├── has_or_had_label  (street name as Label, e.g., "Museumstraat")
      ├── postal_code       (e.g., "1071 XX")
      ├── locality          (e.g., "Amsterdam")
      ├── region            (e.g., "Noord-Holland", "NL-NH")
      ├── country_name      (e.g., "Netherlands", "NL")
      └── has_or_had_label  (formatted address as Label)
      ```
      NOTE: street_name slot migrated to has_or_had_label + Label (2026-01-17, Rule 53/56)
      NOTE: street_address slot removed - was redundant string; use house_number + has_or_had_label (2026-01-17, Rule 53/56)
      **ADDRESS TYPES FOR HERITAGE CUSTODIANS**:
      | Type | Use Case |
      |------|----------|
      | `HEADQUARTERS` | Main organizational address |
      | `LEGAL` | Registered legal/business address |
      | `VISITING` | Public visitor entrance |
      | `MAILING` | Correspondence/postal address |
      | `STORAGE` | Depot, warehouse, off-site storage |
      | `BRANCH` | Branch office location |
      **USAGE EXAMPLES**:
      ```yaml
      # Simple address with formatted string
      has_or_had_address:
        - address_formatted: "Museumstraat 1, 1071 XX Amsterdam, Netherlands"
          address_type: HEADQUARTERS
      # Structured address with components
      has_or_had_address:
        - has_or_had_label:
            - has_or_had_label: "Museumstraat"
              language: "nl"
          has_or_had_section:
            - has_or_had_value: "1"
          postal_code: "1071 XX"
          locality: "Amsterdam"
          region: "Noord-Holland"
          country_name: "NL"
          address_type: HEADQUARTERS
          latitude: 52.3600
          longitude: 4.8852
          geonames_id: 2759794
      ```
      **RELATIONSHIP TO OTHER CLASSES**:
      - `AuxiliaryPlace`: Uses Address for structured address data
      - `CustodianPlace`: May reference Address for place location
      - `ContactPoint`: Uses Address for contact location
      - `Settlement`/`Subregion`/`Country`: Hierarchical geographic entities
      **PROVENANCE**:
      Address data may be extracted from various sources (websites, Google Maps, 
      registries). Track provenance with:
      - `was_derived_from`: Link to source observation
      - `is_or_was_generated_by`: Link to extraction activity

    comments:
      - vCard Address is the primary ontology class (RFC6350 standard)
      - Use structured components when available, address_formatted as fallback
      - Multiple addresses supported via has_or_had_address slot (multivalued, Rule 39 compliant)
      - address_type distinguishes headquarters, legal, visiting, mailing, storage
      - Coordinates (lat/lon) optional but recommended for visualization/mapping
