A friend and i have extract all the data (need fix some little bug) from VISA (April 2023) : https://usa.visa.com/content/dam/VCOM/download/merchants/visa-merchant-data-standards-manual.pdf

@greggles Do you have any ideas on how to arrange this in your core json? Do you have a proposal?

Personally, I like the fact of having a general indication of the type of MCC as well as a more defined description.
The airline example. I like to know that my MCC is : Airlines and Air Carriers and that the description of my MCC corresponds to the airline.
