Page 36 - Redefining smart city platforms: Setting the stage for Minimal Interoperability Mechanisms - A U4SSC deliverable on city platforms

These examples aim to show all the steps and capabilities needed to take data from a range of
different sources and transform them into enabling components of various smart city services.

Based on existing solutions, it is essential to identify a minimum set of characteristics that are true
of all the main reference architectures in use, and then use this to enable the digital marketplace
for cities.

The SynchroniCity Project studied many models and approaches to smart city platforms with
24
the aim of maximizing interoperability and fostering integration with existing local solutions and
technical infrastructures in any city. It developed an architecture framework that collects the most
25
common capabilities and technologies needed by cities and is easily extendable for cities that want
to extend their existing framework.

To do this, 12 different reference architectures developed by international standards organizations
including: ITU-T FG-SCC, ITU-T Y.2060, ISO/IEC JTC 1, oneM2M, AIOT and a number of programmes
and projects were reviewed to identify the core characteristics in common. This was to ensure
that the reference architecture reflected best practice from around the world. The reference
architectures used by eight reference cities were also reviewed in detail to compare the technical
requirements those cities had identified as important. From this work, the project developed a
generic architecture that can be implemented with different technologies by cities and communities
characterized by different levels of “maturity” in terms of IoT infrastructure. 26
