After several years of research and real project implantation in Smart Cities, the lack of broadly used standards starts to be a key problem in the success of Smart City concept and it is source of interoperability problems, makes smart services reuse impossible, originates a lack of compatible devices, etc.
At governance level, a unified vision/standard would enable city authorities to share objectives, measurements and returns of Smart City projects.
One of the most important standardization efforts is done by ISO/TC 268 Sustainable cities and communities (https://www.iso.org/committee/656906/x/catalogue/), which has developed a set of standards regarding Smart Cities. The most relevant documents are.
1.- ISO 37100:2016 Sustainable Cities and Communities – Vocabulary.
2.- ISO 37106:2018 Sustainable Cities and Communities – Guidance on establishing Smart City operating models for sustainable communities.
3.- ISO 37120:2018 Sustainable Cities and Communities – Indicators for city services and quality of life.
In the field of data interoperability, the reference published in 2017 for the ISO/JTC1/WG 11 is ISO/IEC 30182:2017 Smart City concept model – Guidance for establishing a model for data interoperability.
At technical level, the IEC/SYC SMART_CITIES (https://www.iec.ch/dyn/www/f?p=103:217:8810481925515::::FSP_ORG_ID,FSP_LANG_ID:13073,25) electrotechnical aspects of Smart Cities are working in a set of drafts for a unified vision of a Smart City architecture. The most promising approaches include IEC 63205 ED1 Smart Cities Reference Architecture, and the vocabulary definition of Smart City Systems (IEC 60050-831 ED1).
In Spain and in close collaboration with international organisms, the CTN 178 (https://www.une.org/encuentra-tu-norma/comites-tecnicos-de-normalizacion/comite/?c=CTN%20178#.WTbCCGjyhhE) Smart City technical committee group is really active in Smart City standard design (with subgroups of infrastructures, indicators and semantics, mobility and transport, energy, touristic destinations and government/public services).
The most important standard of the CTN 178 are the related with a set of KPI’s (including the methodology and publication procedures) for different domains in the Smart City (water infrastructure, transport networks, open data, wireless sensors networks, irrigation, smart tourist, etc.).
CitiSim architecture/services should converge with this emerging standard in different vertical domains to be compliant with other services/providers. Standards compatibility always makes easier the business in an ecosystem such as the one CitiSim consortium wants to establish.
