Every subject — a group of data models — has a file named contex.jsonld at their root.
This file contains the @context with automatically generated IRI for the terms used in the data model.
The Entity types are also available in this file with their long IRI. In the pointed example are the entries for “SeaConditions”, “WeatherAlert”, “WeatherForecast”, and “WeatherObserved”
Remember that if you want to use other IRI coming, for example, from existing ontologies you can use the service on the Home -> Tools -> Mapper @context with external ontologies
