Worked on the plotly/plotly.py repository to standardize citation metadata by renaming the existing plotly-py-citation.yml file to CITATION.cff, aligning with the Citation File Format standard. This change focused on improving interoperability and discoverability of citation information across platforms and tools, without altering any functional code. The update involved configuration and metadata management, ensuring the repository met industry best practices for citation documentation. Utilized skills in Python and YAML, with attention to repository hygiene and cross-platform compatibility. The work was delivered as a single, well-documented commit, reflecting a targeted approach to non-functional improvements in open-source project maintenance.
