Wrapper for NGSI-LD working on top of NGSIv2 implementations
See https://github.com/Fiware/NGSI-LD_Wrapper/
This repo will be closed soon.
The purpose of this project is to create an implementation of NGSI-LD, based on a wrapper (incarnated by a proxy) on top of the FIWARE Context Broker. Leveraging on FIWARE NGSI, NGSI-LD is an international standard developed by ETSI ISG CIM, intended to provide, consume and subscribe to context information in multiple scenarios and involving multiple stakeholders. It enables close to real-time access to information coming from many different sources (not only IoT).
The OMA NGSI-9/10 information model, the root basis of FIWARE NGSI, is currently being evolved by ETSI CIM to better support linked data (entity’s relationships), property graphs and semantics (exploiting the capabilities offered by JSON-LD). The resulting specification has been named NGSI-LD. It is noteworthy that the NGSI-LD information model is a generalization of the OMA NGSI-9/10 information model. As a result, it is expected a good level of compatibility and a clear migration path between both information models.
This wrapper works on top of the FIWARE Context Broker and basically adapts between NGSIv2 (JSON) representations and the NGSI-LD (JSON-LD) representations.
An example illustrating the usage of NGSI-LD can be found here.
