Marius updated the NavigaTUM repository to enhance the accuracy of FSEI office location data, focusing on reflecting temporary relocations due to construction. He implemented a data management solution using YAML, introducing a temporary override for the affected offices and ensuring that user-facing maps and search results displayed current, reliable information. His approach emphasized clear documentation and versioned changes, supporting ongoing data governance and repository maintenance. By surfacing relocation notes directly in discovery flows, Marius addressed potential user confusion and aligned the data with campus operational realities. The work demonstrated careful attention to detail and a disciplined approach to structured data updates.
