Adding Nested Properties/JSON

[Darren Govoni]

Hi,
   I want to use Nifi to design a flow that modifies, updates, etc a nested 
JSON document (or that can finally output one at the end).

For example:

{
   "name":"this and that",
   "field":"value",
   "others": [
       {"name":"here and there"},
       ...
   ]
}

What's the best approach to this using Nifi?

Thanks in advance!
Darren
