Benefits, Adoption Barriers and Myths of Open Data and Open Government

Abstract: Although a significant number of public organizations have embraced the idea of open data, many are still reluctant to do this. One root cause is that the publicizing of data represents a shift from a closed to an open system of governance, which has a significant impact upon the relationships between public agencies and the users of open data. Yet no systematic research is available which compares the benefits of an open data with the barriers to its adoption. Based on interviews and a workshop, the benefits and adoption barriers for open data have been derived. The findings show that a gap exists between the promised benefits and barriers. They furthermore suggest that a conceptually simplistic view is often adopted with regard to open data, one which automatically correlates the publicizing of data with use and benefits. Five ‘myths’ are formulated promoting the use of open data and placing the expectations within a realistic perspective. Further, the recommendation is given to take a user’s view and to actively govern the relationship between government and its users.

Systematisation of Interoperability Body of Knowledge: the foundation for Enterprise Interoperability as a science

Abstract: The recently posed challenge of developing an Enterprise Interoperability Science Foundation EISF prompted some academic agents to attempt a systematisation of the Interoperability Body of Knowledge IBoK. Still in their embryonic stages, these efforts have sought to organise and aggregate information from very fragmented and disparate sources, and with different granularities of detail, distinct epistemology origins, separate academic fields, etc. This paper aims to distinguish between levels of specificity of the Interoperability academic work, which are often confused, by considering Models, Theories, and Frameworks. The paper revises these concepts within the context of the EISF's recent work. The results presented here, reflecting consultation with the expert community, provide the synthesis of the current state of play regarding the work developed by the Enterprise Interoperability EI at the European Commission's Future Internet Enterprise Systems FInES cluster.

The internet of things: a survey

Abstract: In recent year, the Internet of Things (IoT) has drawn significant research attention. IoT is considered as a part of the Internet of the future and will comprise billions of intelligent communicating `things'. The future of the Internet will consist of heterogeneously connected devices that will further extend the borders of the world with physical entities and virtual components. The Internet of Things (IoT) will empower the connected things with new capabilities. In this survey, the definitions, architecture, fundamental technologies, and applications of IoT are systematically reviewed. Firstly, various definitions of IoT are introduced; secondly, emerging techniques for the implementation of IoT are discussed; thirdly, some open issues related to the IoT applications are explored; finally, the major challenges which need addressing by the research community and corresponding potential solutions are investigated.
