`_meta` field

edit

Each mapping type can have custom meta data associated with it. These are not used at all by Elasticsearch, but can be used to store application-specific metadata, such as the class that a document belongs to:

PUT my_index
{
  "mappings": {
    "user": {
      "_meta": { 
        "class": "MyApp::User",
        "version": {
          "min": "1.0",
          "max": "1.3"
        }
      }
    }
  }
}

This _meta info can be retrieved with the GET mapping API.

The _meta field can be updated on an existing type using the PUT mapping API.
