Reusing data is key for the future of cities and regions, not only to improve policy but also to respond to citizens’ needs and improve services overall. However, this involves obstacles such as the lack of appropriate infrastructure, which is often costly. In this workshop, we’ll present the Big Data Test Infrastructure (BDTI), a free, open-source stack for experimenting with data. Join us to learn more about the BDTI community and kickstart your data analytics journey!
