Wow! A publication reaching 1000 citations is absolutely exceptional, but the report and derived congress paper I co-authored with Rudolf Giffinger, Christian Fertner, Hans Kramar (all at TU Vienna) and Nataša Pichler-Milanović (University of Ljubljana) back in 2007 managed to do just that. Reason: it was one of the very first documents conceptually discussing and measuring the concept of ‘smart cities’ that became hugely popular in the scientific and policy domain in the last decade. Great to see that it inspired the work of so many others after us!
The website we launched in 2007 is still online and updated by the TU Vienna team: http://www.smart-cities.eu/
