Over a three-month period, contributed to the astropy/astropy repository by developing and integrating a VOTable DataOrigin provenance metadata extraction feature, enabling reliable capture of data lineage and improving reproducibility for scientific workflows. This work involved designing Python classes to represent query and dataset origins, implementing XML parsing logic, and extending the API to support richer provenance association. Comprehensive pytest-based unit tests and detailed documentation updates ensured maintainability and usability. Later, focused on API stability by introducing backward compatibility enhancements for older data structures, preserving data access patterns and reducing upgrade risk for downstream users relying on legacy models.

Feb 1, 2025February 2025 summary for astropy/astropy: Delivered a new VOTable DataOrigin provenance metadata extraction feature to improve data lineage and reproducibility. Implemented end-to-end support to extract provenance metadata from VOTable files, including classes to represent query origin and dataset origin information and parsing logic to populate provenance metadata across multiple levels of a VOTable structure. This work is tracked under commit 41bbc8ca0b2a81ce8ecce8331a79ed9095c9433e. Major bugs fixed this month in this area: none. Impact: enables reliable provenance capture during I/O, reducing manual metadata handling and improving reproducibility and VO-standard compliance for VOTable-based workflows. Technologies/skills demonstrated: Python, parsing, provenance data modeling, object-oriented design, and integration with Astropy's I/O/provenance framework.
