During the month, contributed a schema extension to the Amsterdam/amsterdam-schema repository, enabling support for commercial real estate properties within the Stelsel van Dienstverleners framework. Focused on data modeling and schema definition, the work involved adding the bedrijfsonroerendgoed scope while ensuring alignment with existing data contracts and framework conventions. The implementation, managed through Git-based workflows and using JSON, was designed with a minimal surface area to reduce integration risk and facilitate adoption by downstream services. This feature expanded the schema’s capabilities, supporting improved analytics and data quality for commercial property data without introducing major bugs or compatibility issues.
