We have here a Python API for fetching data from Mongo and either returning the raw JSON or a formatted, “parsed,” one. There is certainly a number of things that could be improved (it has been written by a non-programmer and no Python expert, so it is actually a real achievement for him) but what I want to focus on is the API exposed to the clients.
It troubles me because the API exposes too many details about its inner workings and forces the clients to know them.
