Data Exchange and Context Information Standards
Overview
The data exchange layer of the Intelligent Universal Data Exchange (IUDX-Novo) platform follows the NGSI-LD (Next Generation Service Interfaces – Linked Data) standard.
NGSI-LD is a context information management specification designed to support the exchange of contextual, real-time, and dynamic data across heterogeneous systems. It defines a standardized API and information model for representing entities, attributes, relationships, and their temporal and spatial context.
NGSI-LD Adoption in IUDX-Novo
The platform leverages NGSI-LD to ensure consistent, interoperable, and extensible data exchange across domains.
Key characteristics of NGSI-LD usage in the platform include:
Context-aware data exchange, enabling systems to interpret data in relation to its environment
Standardized entity and attribute modeling for uniform data representation
Support for temporal and geospatial properties, enabling time-based and location-aware queries
Linked-data-based extensibility, allowing data models to evolve without breaking compatibility
Data Representation
All context data is represented using JSON-LD, which provides:
Semantic interoperability across systems
Extensible data models through linked data vocabularies
Compatibility with web and semantic technologies
The use of JSON-LD enables the platform to extend data models without requiring changes to core APIs or platform interfaces.
Benefits of NGSI-LD
Adopting NGSI-LD ensures that the data exchange platform:
Remains domain-agnostic, supporting multiple sectors and use cases
Enables rich contextual representation of data
Facilitates interoperability with other NGSI-LD–compliant platforms and ecosystems
Supports scalable, real-time, and dynamic data exchange
Role in the Platform
Serves as the foundational standard for data exchange and discovery
Enables unified handling of contextual, temporal, and spatial data
Strengthens cross-sector interoperability and reuse of data services
