Json schema for 2 level json

[vishwaratna]

Hi, I am following json schema example https://github.com/xitongsys/parquet-go/blob/master/example/json_schema.go for reference.
I have struct which looks like below:

type DataTwoLevel struct {
	ColumnsChangedJson     []struct {
		SourceSystemName string
		Id               int64
		Demographics     []struct {
			Country  string
			Language string
		}
	}
}

I am trying to create a json schema for the same but not able to do so, can someone help me with a concrete example?

My current schema is as below, but it does not work.

`{
  "Tag": "name=parquet_go_root, repetitiontype=REQUIRED",
  "Fields": [
    {
      "Tag": "name=columnsChangedJson, inname=ColumnsChangedJson, type=LIST, repetitiontype=REQUIRED",
      "Fields": [
       {"Tag": "name=element, repetitiontype=REQUIRED",
        "Fields": [
         {"Tag": "name=sourceSystemName, inname=SourceSystemName, type=BYTE_ARRAY, repetitiontype=REQUIRED"},
         {"Tag": "name=id, inname=Id, type=INT64, repetitiontype=REQUIRED"}
         {"Tag": "name=demographics, inname=Demographics, type=LIST, repetitiontype=REQUIRED",
         "Fields": [
           {"Tag": "name=element, repetitiontype=REQUIRED",
             "Fields": [
              {"Tag": "name=country, inname=Country, type=BYTE_ARRAY, repetitiontype=REQUIRED"},
              {"Tag": "name=language, inname=Language, type=BYTE_ARRAY, repetitiontype=REQUIRED"}
           ]}
         ]}
        ]}
      ]
    }
  ]
}`
