Worked on the soot-oss/SootUp repository to enhance citation metadata reliability by addressing a specific issue in the CITATION.cff file. Focused on correcting the DOI format, the work involved careful metadata management and citation formatting using YAML. This targeted fix ensured that academic references generated from the repository would be accurate and compatible with downstream tools that rely on precise citation data. No new features were introduced during this period, as the primary objective was to maintain data integrity and interoperability. The approach emphasized low-risk, high-impact maintenance, contributing to the overall quality and trustworthiness of the project’s metadata.
