> +Question:+
> Fiware orion /op/query endpoint working explaination
> +Description:+
> I'm a student learning the fiware ecosystem. From my previous explorations, I learned how Orion can use proxy services to use external context providers to fetch dynamic context data. Here I understood how different endpoints can provide different responses from the given example code which is an express.js application. But I am confused on a few points and want to know working of these.
> How is the Orion batch query able to hit the data if there is no /op/query endpoint defined in the example code?
> In the commented section there is these endpoints of the format /random/temperature/ngsi-ld/v1/entities/, In these does Orion append the ngsi-ld/v1/entities/ part whenever the context of the Store entity is requested using orion/v2/entities/<entity-id> endpoint?
> If orion context broker somehow directs these queries to the proxy by altering them, Where can I get code of the context broker itself for better understanding?
> I am working on my college project and any help is appreciated. Thanks in advance.
