platforms and third parties, to offer urban operation and services supporting the functioning of city
services, as well as efficiency, performance, security and scalability. Furthermore, Recommendation
ITU-T Y.4200 (ITU, 2018a) defines the requirements for the interoperability of a smart city platform
and its reference points in order to ensure the correct functioning of city services
Figure 1: a� Overview of an SCP and external systems/platforms (ITU, 2018), b� a generic SCP
logical architecture
A generic architecture that is being followed is depicted in the following (Figure 1a), which can be
explained with (Figure 1b) and shows that the SCP is accompanied by APIs that enable connections
with IoT in the city, local systems, and other software applications. Additionally, the SC platform
offers secure identities (IDs) for these connections and software utilities (SDKs) to the developers,
who want to visualize the data that their applications share with the platform. The platform can
visualize the data that it collects from its API connections by validated connected contributors.
