gistfile1.js

// de-normalized
{
  "_id": <ObjectId1>,
  "name": {
    "en": "Eugene",
    "uk": "Євген"
  }
}

//or normalized
//1st data collection
{
  "_id": <ObjectId1>,
  "name": "1"//reference to id of 2nd collection
}

//2nd i18n collection
[
  {
    "_id": <ObjectId2>,
    "id": "1", //reference to name of 1nd collection
    "value": "Eugene"
  },
  {
    "_id": <ObjectId2>,
    "id": "1", //reference to name of 1nd collection
    "value": "Євген"
  }
]
