JSON, nested json objects NOT arrays

So basically i am playing with JSON and nested JSON objects (not in the form of arrays []) using structs. I bet this is really simple but why am i struggling to create a nested JSON object 1 level deep using two struct types?

package main

import (
	"encoding/json"
	"fmt"
)

type MetaData struct {
	Country string `json:"countryScope"`
	Asset   string `json:"assetScope"`
}

type BusEvent struct {
	MedaData MetaData `json:"metaData"`
	Name string
}

func main() {
	resp := BusEvent{
		MetaData{
			Country: "test",
			Asset:   "test",
		},
		Name: "test",
	}
	js, _ := json.Marshal(resp)
	fmt.Printf("%s", js)
}

https://play.golang.org/p/siMDC2MNX-V

The failure is as follows:

./prog.go:20:11: mixture of field:value and value initializers

This (MedaData) is probably a typo.

The error message says it all. Do this:

	resp := BusEvent{
		MetaData: MetaData{
			Country: "test",
			Asset:   "test",
		},
		Name: "test",
	}

But this is not related to JSON, just how structs are build.

See https://play.golang.org/p/VPHrxqTa6aU for the output:

{"metaData":{"countryScope":"test","assetScope":"test"},"Name":"test"}

Thank you @lutzhorn! I knew someone would just put me on the straight an narrow. Brilliant thank you.
