Confusion on relationships in author example

2

My first thought was that there should be a people and ai links type

{
  "type": "articles",
  "id": "1",
  "attributes": {
    "title": "Rails is Omakase"
  },
  "relationships": {
    "authors": {
      "links": {
        "self": "/articles/1/relationships/author",
        "related": "/articles/1/author",
        "people": "/people",
        "ai": "/ai"
      },
      "data": [
        { "type": "people", "id": "9" },
        { "type": "ai", "id": "2" }
    }
  }
}```
