This document discusses the Öresund Smart City Hub project, which aims to create an open data platform to spur innovation using public sector data from municipalities in the Öresund region. The project seeks to (1) use challenges related to sustainability goals in municipalities to drive economic growth, (2) create a cross-border platform for collaboration opportunities, and (3) make the region a leading smart city test bed.
