Michel Buechner addressed a metadata consistency issue in the MyCoRe-Org/mir repository by refining the JATS to MODS XML transformation process. He implemented an XSLT-based solution that ensures only the first subtitle element is imported during conversion, effectively preventing duplicate subtitles and related data inconsistencies in downstream systems. By aligning the fix with the MIR-1469 reference, Michel improved traceability for future audits and streamlined metadata quality for DeepGreen imports. His work demonstrated proficiency in XML transformation and debugging, with a focus on maintaining metadata standards and reducing the need for downstream cleanup in MODS exports, search, and display systems.
