Why Data Matters: Data Products and Data Services for Smarter Cities

Smart cities are built on more than technology. They are built on data. Every day, cities generate vast amounts of information, from traffic and public transport to energy consumption, air quality and public services. When this data is managed effectively, it becomes a powerful resource for improving urban life.

However, data alone has limited value. To support better decision-making, it needs to be organised, shared and transformed into practical solutions.

This is where data products and data services play a key role. A data product is a curated and well-documented collection of data that can be easily accessed and reused. A data service uses this information to deliver practical tools, such as dashboards, analytics, forecasting models or digital applications that help organisations make informed decisions.

For a Smart City, these capabilities are essential. Data products and services enable city authorities to better understand how the city functions, optimize public services, monitor sustainability goals and respond more effectively to citizens' needs. They also encourage collaboration between public authorities, businesses, researchers and other stakeholders by enabling trusted and secure data sharing.

The CityScape use case demonstrates how this approach can be applied in practice in Cluj-Napoca. By bringing together data from different urban domains in a trusted data space, CityScape supports the development of data-driven services that help the city make more informed decisions while maintaining secure and interoperable data exchange.

As Cluj-Napoca continues its journey as a Smart City, initiatives such as CityScape demonstrate how trusted data sharing, data products and data services can support better urban planning and more informed decision-making. By turning data into practical solutions, the city is creating the foundations for more efficient public services, greater sustainability and a better quality of life for its citizens.
