What is is correct term for fields like author in the below:

PUT /publications
{
  "mappings": {
    "properties": {
      "id": { "type": "text" },
      "title": { "type": "text" },
      "abstract": { "type": "text" },
      "author": {
        "properties": {
          "id": { "type": "text" },
          "name": { "type": "text" }
        }
      }
    }
  }
}

You mean author.id? That'd be a nested field.

But what would you call author? A placeholder? field header? folder? :smiley:

It is a field mapped as an object as it contains other fields.
