Developed PURL Handling Utilities for the oss-review-toolkit/ort repository, focusing on improving package URL processing within backend systems. The work involved implementing Kotlin-based utilities to map PurlType enums to ORT identifier strings and to parse PURL strings into their component parts, enhancing the accuracy of dependency metadata extraction. By introducing clear module separation and comprehensive unit testing, the changes supported more reliable downstream license and vulnerability scanning workflows. The approach emphasized maintainable code structure and contributor standards, leveraging skills in data parsing, Kotlin, and backend development to address the need for precise and robust dependency information in open source review processes.
