Smart cities go hand in hand with evolvement and improvement of digital technology. They are a post-industrial reaction to the economic, social and political changes and challenges the world has been facing throughout the last decade – like the demographic change, the financial crisis or scarcity of resources. In cities there are plenty of players with very different tasks and interests. Many of them are trying to own the term "Smart city". It is somehow fascinating to compare the different interpretations of this label – from a geographic point of view (for example in Europe, USA, China, ...), through its perspective (humans and quality of life or technology and efficieny as centre point?), or generally from an economic position (potential savings on the one hand, rapidly growing business field on the other hand) and via approaches to standardisation of the city and its services. There are lots of methods to achieve smartness, and there are lots of approaches to define proper smart indicators that tell us something about the smartness of a city. What are their advantages or disadvantages, which approach may claim to be the right one – and why?
