==List of data description languages==
A significant part of RESTful API description is the specification of returned data structures. The IDL might either specify its own format or use an existing data description format. A notable example which many RESTful API DLs use is [[JSON Schema]].
*json:api
**http://jsonapi.org/
**Started as REST adapter for [[Ember.js|Ember]] Data
*JSON Schema
**used by OpenAPI, Google APIs Discovery,<ref>{{Cite web|url=https://developers.google.com/discovery/v1/reference/apis|title=Discovery Document | Google API Discovery Service}}</ref> I/O Docs
*Apache Avro
