During March 2025, JBB focused on data governance within the MobilityData/mobility-database-catalogs repository, addressing a critical maintenance issue by deprecating the ZET feed from the Transitfeeds data source. Using Python and leveraging skills in API integration and data cataloging, JBB removed the ZET entry and disabled its future ingestion, thereby preserving the integrity of the transit data catalog. This targeted change reduced the risk of data drift and ingestion errors, directly improving catalog-aware analytics. The work demonstrated careful change management and version control, linking the update to a specific commit and ticket for traceability and ongoing data quality assurance.
