10 Commits • 3 Features
Nov 1, 2025November 2025 highlights: The opensanctions data pipeline delivered measurable business value through bug fixes, data enrichment, robustness improvements, and enhanced observability. Key bug fixes improved data quality and ingestion reliability across datasets (dedupe threshold tuning for US BIS Denied, US medical exclusions patches, and sg_gov_dir handling of HTTP 403). New features enriched sanctions data with richer Polish address formats and expanded country code mappings for pl_wanted. Ingestion robustness was improved via better parsing of multi-value fields, reliable URL discovery for Bundestag, and stricter file handling/validation in Cyprus. Additionally, monitoring and telemetry for the Spanish Parliament crawler enables easier troubleshooting and observability. Collectively, these changes increased data accuracy, reduced ingestion failures, and provided actionable insights for operations, analytics, and compliance teams.
