however, this evidence shows that the term “smart city platform” (Teslya et al., 2019) emerges, while
it is also seen as “smart city control system” (Sanchez et al., 2019).

It is beyond the purposes of this document to analyse the corresponding literature but, a brief look
on the collected articles show that several platform installations exist around the world: some cities
use open platforms (e.g., FIWARE (2020) in Takamatsu city, Japan (Ishii and Yamanaka, 2018)), while
others have installed commercial products that also serve the demand for city’s data collection,
analysis and visualization, and for remote utility management (Anthopoulos, 2019) (Table 2).

The analysis of the above products shows that all these platforms are cloud-based and are
being offered with the Software-as-a-Service (SaaS) model. These implementations necessitate
international standards such as Recommendations ITU-T Y.4201 and Y.4200. More specifically,
Recommendation ITU-T Y.4201 presents high-level requirements and a reference framework of
smart city platforms (ITU, 2018) that defines the smart city platform (SCP) as a city platform that
offers direct integration of city platforms and systems, or through open interfaces between city
