Guidelines for Modelling with NGSI-LD

This White Paper is also intended to be complementary to the NGSI-LD Primer (see ETSI GR CIM 008 [2]), which mainly explains how to use the NGSI-LD API (see ETSI GS CIM 009 [3]) (e.g. creating or updating entity instances, queries, subscriptions, etc.) in a more “hands-on” practical way, especially for the initial use cases considered(see ETSI GR IM 002 [4]). The main body of the present document limits the use of the NGSI-LD information model to those features that are compatible with the NGSI-LD API. The use of features of the information model that are not (yet) supported by the NGSI-LD API is explained in the Annex.
