📝 Introduction
node-red-contrib-hypertegrity is a Node-RED node library designed to simplify and standardize data integration into NGSI-LD–based data platforms, with a current focus on the Stellio Context Broker. It provides reusable, low-code building blocks that enable developers to ingest, transform, subscribe to, and publish contextual data without having to deal directly with NGSI-LD API specifics or broker-level details.
The library addresses a common challenge in NGSI-LD projects: bridging heterogeneous data sources and event streams into a consistent, standards-compliant context model. By encapsulating recurring integration patterns in dedicated Node-RED nodes, it significantly reduces boilerplate logic and integration effort.
Core capabilities include:
- NGSI-LD subscription handling, allowing flows to react to context changes and entity updates emitted by a context broker
- A Post-to-Stellio node for reliably publishing NGSI-LD entities, updates, and events to the Stellio Context Broker
- Connectors for common data sources, enabling structured ingestion of external data into NGSI-LD workflows
- A generic NGSI-LD builder node that supports the construction, enrichment, and reuse of NGSI-LD–compliant payloads - based on smartdatamodels
Together, these components form a low-code integration layer for NGSI-LD within Node-RED. The library is intended for use in urban data platforms, IoT and sensor data pipelines, and context-aware applications where data must be modeled, transformed, and exchanged in a standardized and interoperable way.
