Is there a reason Reports, Indicators, Geodatabase, and Ohsome are all written with upper case? The Python modules are all written in lower case.

Is there a reason Reports, Indicators, Geodatabase, and Ohsome are all written with upper case? The Python modules are all written in lower case.

At first api, cli and oqt were all just one file (one python module). The other ones where a lot of python modules (E.g. indicators).

But in this diagram I think it is okay to "paint the picture" in abstract terms. So I capitalized all module names. api.py is now just API.
