Feb 1, 2026February 2026 monthly summary for etalab/transport-site focused on delivering data quality, validation, and consolidation improvements that drive business value and reliability. Key features delivered include improved geopoint input validation, a dataset consistency checker script to surface dataset disparities between datagouv consolidation and local transport consolidation, and IRVE consolidation enhancements with new metadata fields, refined import/export logic, deduplication, and clearer reporting. A noteworthy bug fix disabled an unnecessary dataset subtype search in dataset filtering to streamline UX and prevent invalid filtering paths. Impact highlights: higher data integrity for geopoint inputs, visibility into cross-dataset consistency, reduced duplicates in IRVE consolidation, and a clearer, more maintainable reporting structure. These changes enhance data trust, operational correctness, and downstream analytics for transport datasets.

This reduces onboarding time and setup errors for new contributors. (Commit: 6f9209547672092304e1aa7528f4b5486c680ae0) - IRVE Data Processing: Static Schema Validation and Preprocessing: Refactored IRVE file processing to drive validation and preprocessing from a static schema, added separate preprocessing for coordinate and boolean fields, and introduced tests ensuring IRVE data is read and processed as a DataFrame. This strengthens data quality and repeatability for downstream analytics. (Commit: 39e5f5344b82ff83aa52ad7809dcc4bd91d95f86) Major bugs fixed: - No major bugs fixed this month. Primary focus was on feature delivery, code quality improvements, and expanding test coverage. Overall impact and accomplishments: - Faster developer onboarding and reduced setup friction due to clearer ASDF usage guidance. - More reliable IRVE data ingestion and preprocessing through static validation schemas and targeted preprocessing steps, supported by tests and DataFrame-based processing. - Established foundation for scalable data validation, improving data quality for downstream dashboards and analytics. Technologies/skills demonstrated: - Python data processing, DataFrame-based pipelines (pandas), static schema validation, and test-driven development. - Documentation best practices and contributor onboarding improvements. - Version management and DevEx alignment through precise command guidance and reproducible setup steps.

May 1, 2025Month: 2025-05 — Delivered two high-impact features for etalab/transport-site focused on performance optimization and security policy simplification. Implemented preemptive caching for home page statistics with conditional startup of caching modules and a new preemptive caching module, plus alignment of cache TTL with the strategy. Also updated the Content Security Policy to allow all HTTPS image sources, simplifying image integration while maintaining security posture. These changes are expected to improve homepage load times, reduce backend load during peak access, and accelerate content rendering.
