Developed a comprehensive music encoding file for Beethoven’s Symphony No. 9 within the BeethovensWerkstatt/data repository, focusing on detailed score definitions and instrument measures to enhance corpus management. Leveraged XML and music notation expertise to design schema supporting robust data completeness, enabling advanced indexing, search, and potential playback workflows. The work involved careful structuring of musical data to ensure accuracy and extensibility, with all changes managed through disciplined version control and collaborative merge workflows. No major bugs were reported during the period, reflecting a focus on feature delivery and code stability. The contribution demonstrates depth in XML schema design and music encoding.
