Pietro Liuzzo focused on enhancing data quality within the BetaMasaheft/Manuscripts repository by addressing a metadata issue in manuscript records. He performed targeted XML data cleaning, specifically correcting the idno element in DWdavies01.xml to prevent downstream processing errors and improve the reliability of search and export functions. Using XML manipulation skills, Pietro validated the corrected data against the repository schema, ensuring compliance and minimizing risk of future ingestion issues. Although the work involved a single, precise data correction rather than code changes or new features, it demonstrated careful attention to data integrity and strong adherence to change-control best practices.
