You can define metadata attributes for each file that you host with
MongoDB Realm. Metadata attributes map to standard HTTP headers and allow you to optionally configure how Realm
serves your files as well as how clients that request resources should
handle them. This page provides examples and describes the purpose of
each available attribute.
The Content-Language file
attribute optionally specifies the language used by the file's intended
target audience. This attribute does not necessarily represent the
language that file is actually written in.
