Worked on the RConsortium/submissions-pilot5-datasetjson repository to update the adam-pilot-5.xlsx dataset specification, ensuring the data structure and content reflected recent changes required by ingestion pipelines and downstream consumers. Focused on data governance and clarity, the work involved revising the Excel data file without modifying code, emphasizing traceability and reproducibility through detailed commit history. Utilized Excel for data modeling and documentation, and collaborated with stakeholders to align the dataset with evolving requirements. The update reduced ambiguity for data readers and improved documentation practices, supporting robust data ingestion workflows and maintaining consistency across the data lifecycle within the repository’s ecosystem.
