Cyrille Fougerouse contributed to the iptv-org/epg repository by enhancing data quality and interoperability within the EPG service. Over two months, Cyrille implemented XMLTV ID support by adding a dedicated column to the database, enabling more robust data integration and lookup across XMLTV sources. He also addressed data consistency by deduplicating and standardizing channel information in XML files, which improved the reliability of the EPG feed. His work involved database management, data cleaning, and XML data manipulation, using SQL and XML to ensure traceable, migration-ready changes. These efforts laid a foundation for streamlined data ingestion and downstream service integration.
