WELCOME
The EU LDT Data Platform is the central data backbone of the EU LDT Toolbox, enabling cities to ingest, manage, unify, and query data from multiple heterogeneous sources in a secure and interoperable way.
It provides a standardised, scalable, and real-time data environment, allowing municipalities to transform fragmented datasets into actionable insights. By combining context data management (NGSI-LD), federated querying, and advanced data services, the platform ensures that all tools within the ecosystem operate on a shared, reliable, and consistent data layer.
THE CHALLENGE
Cities today operate with highly fragmented data ecosystems:
- Data is distributed across multiple systems (IoT platforms, databases, APIs)
- Different formats and standards limit interoperability
- Real-time and historical data are often disconnected
- Access control and governance are inconsistent across services
This fragmentation makes it difficult to:
- Build reliable digital twins
- Run simulations and AI models
- Ensure data-driven decision-making
The challenge is not only to collect data, but to standardise, unify, and make it accessible in a secure and scalable way across the entire ecosystem.
HOW IT WORKS
The EU LDT Data Platform acts as a unified data orchestration layer, combining multiple components into a single, coherent system.
It acts as the single source of truth, ensuring that all tools operate on consistent, standardised, and interoperable data.
By abstracting the complexity of data integration and providing unified access mechanisms, it enables the ecosystem to function as a cohesive and scalable digital twin environment.
The tool connects multiple data sources, including IoT devices, APIs, and databases. Data is ingested and transformed into a standard format, enabling seamless integration across systems.
Using NGSI-LD, the platform structures data into a shared context model. This allows real-time updates, subscriptions, and consistent interpretation of information across tools.
Data is stored across distributed systems, supporting both real-time and historical datasets. The architecture ensures scalability, reliability, and efficient data lifecycle management.
Through APIs and federated query engines, users can access and analyse data across multiple sources without duplication, enabling cross-domain insights.
INTEGRATION WITHIN THE EU LDT TOOLBOX
Input →
Receives data from IoT devices, APIs, databases, and external systems, including real-time and historical datasets.
→ Output
