Abstract
Urban Data Platforms (UDPs) are increasingly being adopted by cities to collect, analyze, share, and use
data from diverse urban sources. However, data sharing across UDPs from different cities is in its
infancy due to technical, organizational, and regulatory challenges. This paper addresses these issues by
exploring the concept of UDP federation as a decentralized, interoperable approach to supporting crosscity data sharing while ensuring data sovereignty and legal compliance. Using a systematic literature
review approach, we analyzed sixteen peer-reviewed articles and identified five main requirement areas
for effective UDP federation: governance and sovereignty, scalable infrastructure, interoperability, privacy
and security, and regulatory compliance. These findings provide a theoretical foundation for designing
federated data-sharing ecosystems to foster urban innovation among municipalities.
