I suggest you look the other way. https://json-schema.org/ ♪ You can, according to your data, generate the scheme, for example by using one. https://json-schema.org/implementations.html#schema-generators ♪This is an example of your data diagram (used by an online generator) https://app.quicktype.io/#l=schema {
