This document provides an introduction to OData, an open protocol that allows building and consuming RESTful APIs in a simple and standard way. OData exposes data in an easily accessible format over HTTP, and uses common formats like JSON and Atom. It originated from Microsoft's WCF Data Services and aims to provide a standard way for APIs to expose CRUD operations and query data through URLs, headers and request bodies over HTTP.
