Worked on enhancing license identification accuracy for academic publications by updating the ISSN-to-license mapping in the ubtue/zotero-enhancement-maps repository. Focused on data mapping and license management, the contribution involved refining the JSON-based mapping file to reflect recent changes in licensing agreements. This targeted update improved the quality and reliability of downstream licensing analytics and compliance processes. The work was delivered as a single, auditable commit, ensuring transparency and maintainability. By strengthening the data foundation for license management, the update supported more accurate compliance checks and reporting, demonstrating attention to detail and a methodical approach to repository maintenance and data integrity.
