During January 2025, Bodl3519 enhanced the fihristorg/fihrist-mss repository by updating Authority Records to include new persons, expanding the dataset’s coverage and improving metadata completeness. The work involved backend development and data management, with a focus on evolving the data model and updating Python-based data structures to support new entries while minimizing disruption to existing workflows. By applying precise, commit-scoped changes, Bodl3519 enabled more accurate search and retrieval, reducing the need for manual curation. The update demonstrated a methodical approach to schema evolution and version-controlled deployment, resulting in a more robust and discoverable authority file system.
