remoteStorage
Abstract
This draft describes a protocol by which client-side applications,
running inside a web browser, can communicate with a data storage
server that is hosted on a different domain name. This way, the
provider of a web application need not also play the role of data
storage provider. The protocol supports storing, retrieving, and
removing individual documents, as well as listing the contents of an
individual folder, and access control is based on bearer tokens.

containing documents and subfolders. The actions the interface
exposes are:
