_meta fieldedit
A 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": {
"_meta": {
"class": "MyApp::User",
"version": {
"min": "1.0",
"max": "1.3"
}
}
}
}

The _meta field can be updated on an existing type using the
PUT mapping API:
PUT my_index/_mapping
{
"_meta": {
"class": "MyApp2::User3",
"version": {
"min": "1.3",
"max": "1.5"
}
}
}
