Question:
Interfacing Orion and other GEs from fiware and other APIs

Description:
I'm trying to integrate Proton CEP and Mandrill, an email service, mediated by Orion context broker.
When I was starting to study Orion, I thought that it would be able to communicate directly with CEP, exchanging JSON objects through http. And also that Orion would be able to parse each object to deliver to the correct format understandable by each API.

From the examples and documentation available I was able to understand that another API developed by us should be doing the parsing and mediating the communications between each API.

So I'd like to confirm that this is so and that I'm not missing something. Is Orion indeed unable to customize its outputs?

If confirmed, then I will proceed with development of this mediating API.

Edit:
I believe I wasn't clear above about the issue. I hope adding this helps.

Proton CEP recieves through http POST JSON objects, but it only understands the variables if they are in simple format, like

, with no arrays or complex struture.

Orion, can comunicate in JSON as well through http, but I can't control the structure of the JSON output. So the result is that CEP wouldn't be able to understand inputs from Orion and process them. The same issue arises with other APIs too. And I'd like to confirm that Orion is indeed unable to custom its output and that this integration needs to be done on our side.
