udk/index is a digital archive and data collection of the digitally extended annual exhibitions of the Berlin University of the Arts. Since 2021, students and faculty have been able to manage digital content of their semester projects and works via udk/content (an institute-specific instance of the developed medienhaus/CMS) and make them available or publish them for udk/rundgang. Published works remain accessible in udk/index beyond the immediate context of each year, allowing this part of the federated data network to be explored.
