Askhat Abishev enhanced data ingestion and authority resolution workflows by expanding MARC authority field mappings in the folio-org/mod-source-record-manager repository. He introduced support for namedEvent, sftNamedEvent, and saftNamedEvent fields, aligning mapping rules and schema layers to improve processing accuracy and downstream discovery. In parallel, he updated documentation in folio-org/data-import-processing-core, ensuring that schema enhancements and new MARC fields were clearly described for future maintainability. His work leveraged Java, JSON, and Markdown, with a focus on backend development, data mapping, and unit testing. The changes provided better traceability, onboarding support, and a foundation for ongoing schema evolution.
