I could be wrong but using JSON as format for name is not a solution, its abstraction over possible solution. Suppose we store all names as JSON structure. Question - how people will create such structure from their names? Using form with dozens of fields and checkboxes? Second question: how we will display this structure? We have to find a way to convert this JSON into string to show name. And as result we will surely need function to convert this shown strings into JSON for sure. And how we can solve issue when some names could be presented as a bit different JSON structures? And how we can validate that these slightly different JSON structures are equal?
