Usage
Attributes are created and managed via the API, enabling integration with external systems and flexible customization. They allow property management companies to store tailored information such as meter provider IDs, special notes, or other relevant metadata tied to the operational context.
Purpose
Attributes help to maintain a clean and adaptable data model by decoupling extended metadata from the main entity definitions. This allows for scalable and customer-specific extensions without complicating the core database schema.
