This script should be free of parameters as much as possible. Indeed, it should only set up a default configuration. The main.py script will be in charge of getting the user parameters and set them in properties.ini. Otherwise, the ETL will use the default configuration set in properties.ini by the configuration script configure.sh.

[Nelly-Barret]

The idea is to:

• Have a default config file, named properties.ini, with all the parameters and their default value
• Have dynamic parameters, given when calling the main.py script, to override the default parameters, i.e., those in properties.ini
• Create a folder for the currently used database in the working directory and store inside:
  • The metadata file
  • The JSON files before they are sent to MongoDB
  • The configuration after it may has been overidden by the dynamic parameters to keep track of the parameters used to load the current database.

Update: I could also write more info in the config file about the system, date+time of execution, etc. DONE
