The process was marked with a willingness to share, collaborate and learn together in building
city networks, as well as strong commitments to national and international norms and standards
in Smart and Sustainable Cities:

• Spanish Network of Smart Cities. Working group coordinator.

• Red Innpulso, innovation network in cities, member of the management team.
• Committee of Aenor CTN / 178-Smart Cities. Sub-Committee Chairman.

• United for Smart and Sustainable Cities (U4SSC). Thematic group coordinator.

• Member of the Open Agile on Smart Cities.
• Member of the European Association for the Innovation of Smart Cities and Communities.

It should be noted that in 2015, the city of Valencia obtained the ISO 37120 certification “Sustainable
development in cities”, as well as “Indicators of urban services and quality of life” at the platinum
level. In 2018, the city received the U4SSC certification “Key performance indicators for smart cities
to assess the achievement of the sustainable development goals”.

These KPIs allow city managers to analyse the evolution of key aspects of the city, as well as to
compare themselves with others.

10.2 Technological architecture of the urban platform

The public contract for urban platforms defined a set of general characteristics: an open platform
based on open technologies and standards, focused on the future Internet approach with
requirements for security, robustness, horizontality and adaptability, and an architecture based
on layers: management, integration and interoperability, Data Processing, Management and
Exploitation, Business Support, Application and Access. This later constituted the nucleus of the
UNE 178104 standard for integrated city management architecture “Smart Cities: Interoperability
requirements for a smart city platform”.

The winning bid used the Thinking City platform based on the European open-source standard
FIWARE. 14

The VLCi city platform has mechanisms for the acquisition and processing of information through
the IoT Agents, which collect all the observations that come from the devices and transform them
into NGSI events that support the UL2.0, JSON protocols, HTTP and MQTT, as well as the Context
Agent, which is responsible for retrieving, maintaining and entering context information within the
VLCi platform. Concrete evidence of this model is illustrated in the following figure:
