Part 5: Big and Open Linked Data ; International audience ; In the public sector, big data holds many promises for improving policy outcomes in terms of service delivery and decision-making and is starting to gain increased attention by governments. Cities are collecting large amounts of data from traditional sources such as registries and surveys and from non-traditional sources such as the Internet of Things, and are considered an important field of experimentation to generate public value with big data. The establishment of a city data infrastructure can drive such a development. This paper describes two key challenges for such an infrastructure: platform federation and data quality, and how these challenges are addressed in the ongoing research project CPaaS.io.

PurposeThe purpose of the paper is to show that smart item technologies, like RFID and sensor networks, are considered the next big step in business process automation. Through automatic real‐time data acquisition, these technologies can provide benefits to a variety of industries by improving the efficiency of their operations. A service‐oriented infrastructure is proposed that enables the integration of RFID, wireless sensor networks and embedded systems technologies with existing business processes.Design/methodology/approachThis paper discusses the system requirements of a smart items infrastructure in detail. Based on these requirements, the overall infrastructure and the constituting components are introduced. Also, using two real‐world scenarios, it is shown how the proposed infrastructure can be used.FindingsThe paper found a set of technical requirements for a smart items infrastructure. The research resulted in the architectural design presented.Originality/valueTo the best of one's knowledge, this paper is the first to identify and explain the technical requirements for a holistic smart items infrastructure. The service‐oriented system architecture provides a new approach to a flexible/adaptable infrastructure for ubiquitous computing. By pointing out requirements and open issues, the paper identifies interesting topics for future research in this area.

Launching smart city activities and projects requires political support. For sustainable approaches, a concrete strategy, and leadership endorsement from the municipal government is crucial. In accordance with the most prevalent definitions of a smart city, postulating that a city must enhance quality of life and provide benefits to the people living and working there, this book chapter focuses on one specific aspect of public value, the value it can bring to citizens. Through discussion of earlier theoretical approaches and empirical evidence, we provide a framework to better capture, analyze and model value creation in a given municipal ecosystem. By analyzing two different cases- Amsterdam and Winterthur - it becomes clear that "smartness" is not just a state to be achieved, but rather the enablement of processes that continuously and dynamically change the city, improving quality of life by providing different benefits and amenities. The key enablers to develop an ecosystem for a smarter city strategy involve Private-Public-Partnership models, the direct involvement of citizens, the availability of data infrastructures, and social interaction platforms.
