Worked on enhancing the command-line interface documentation for the apache/jena repository, focusing on the Arq CLI tool. Delivered a targeted help text update that clarified the usage of dataset-related options such as --data, --graph, and --namedGraph, providing detailed explanations of usage patterns, supported file types, and URL input handling. The work aimed to reduce user confusion and streamline onboarding by improving both developer and user-facing documentation. Leveraged Java and command-line interface expertise to ensure the documentation aligned with product goals, supporting faster task ramp-up and reducing support overhead. No major bugs were addressed during this period.
