The Dec. 2018 issue of Computer, the flagship publication of the IEEE Computer Society, has the topic of Governments in the age of Big Data and Smart Cities. It is therefore fitting that it contains a feature article on the CPaaS.io project, with the following abstract:
Data-driven cities and governments rely significantly on data collection, management, and distribution platforms. In this article, we introduce CPaaS.io, a collaborative project between Japan and the European Union with the goal of establishing common smart city platforms for deployment in real smart city use cases.
