Growth rates in e-commerce, changing consumer behaviors, and COVID-19 have all put pressure on local retailers worldwide, threatening the resilience of city centers. Local online platforms (LOPs) have been considered as a solution to help local retailers increase their visibility and survive on the market. However, most platforms fail to attract a significant number of stakeholders. Simultaneously, digital platform solutions with more holistic urban perspectives, such as urban data platforms (UDPs), have emerged. However, a question remains: how can the integration of retail data (e.g., product availabilities) into a UDP succeed? Therefore, in this paper, we explore stake-holder-oriented networking processes to integrate local retail data into a UDP in Leipzig, Germany. Leipzig has increased its population by 26% since 2000, but presents the highest retail vacancy rate, compared to other major German cities. To investigate the networking process in Leipzig, we conduct a social network analysis which combines qualitative interviews, mapping, and ethnographic research. We interview ten stakeholders and uncover conflicts within the networking process: First, all stakeholders have different understandings of UDPs and how to integrate local retail data; second, the interviewees acknowledge the importance of, but none of them feel responsible for, initiating or managing the process; and third, the city administration has shown diverging interest, in terms of taking on more responsibility.
