In addition to user-owned addresses, Items may also reference location data esepcially in service-based (Spacetime) marketplaces. Item location data serves different purposes depending on marketplace type:
- Mapping physical products to pickup points (e.g., in-store locations, warehouses).
- Associating services with geographic location.
- Enabling map-based discovery (e.g., service or rental marketplaces).
When an Item requires a location reference, the Address entity is reused as the location record:
- An Item may reference an Address as its location.
- Location-linked Items may be surfaced in map-based interfaces.
- Location data remains structurally separate from shipping calculations.
Item location is a structural attribute of the Item entity and does not inherently define delivery cost or shipping behavior.
| Note: Even if multiple items share the same physical address, each item generates a distinct Address ID upon creation. This ensures item-level independence and location tracking consistency. |
