Jun 1, 2025Month: 2025-06. In Amsterdam/amsterdam-schema, delivered two key schema enhancements focused on data quality, consistency, and governance. First, refined grid metadata for raster datasets (raster 10, raster 100, bor_inspecties) with updates to v1.json and dataset.json, improving data quality and consistency. Second, standardized district terminology by renaming 'buurt' to 'wijk' and incremented the schema version to 1.0.3 across v1.json. These changes reduce downstream data quality issues and simplify governance and interoperability. All changes were tracked via dedicated commits, enabling traceability and easier rollbacks if needed. Overall impact: clearer data definitions, stronger schema governance, and more reliable downstream analytics and dashboards. Technologies/skills demonstrated: JSON schema design, metadata modeling, versioning and governance, Git commit discipline, and collaboration on open data schemas. Business value: improved data quality, interoperability, and governance enabling faster, more reliable decision-making and downstream integrations.
