Setting up the Sirus NGSI-LD Context Broker
- Download the Azure NGSI-LD Context Broker in the Azure Marketplace.
- Follow the different steps for setting up the NGSI-LD Context Broker (make sure you have the necessary rights in your Azure environment).
- After setting up the Context Broker, you can test it via https://REPLACEBYAPPNAME-appservice.azurewebsites.net. You will need to change REPLACEBYAPPNAME by the prefix you filled in during the installation of the Context Broker.
- Wait a few minutes. The first action you send to the URL will take a bit longer since the application is launched for the first time.
- Adding your first entity. To install your first entity, follow these steps. You can use a tool for interaction with Rest APIs like Postman:
- http request POST: https://REPLACEBYAPPNAME-appservice.azurewebsites.net/ngsi-ld/v1/entities‘
- header: ‘Content-Type: application/ld+json’
- Body:
{
"id": "urn:ngsi-ld:Test:001",
"type": "AirQualityObserved",
"humidity": {
"value": 54.45487144274052,

"@context": [

]
}
6. To retrieve the previously created entity:
