Open Data Protocol (OData)

• OData, short for Open Data Protocol, defines a protocol for the querying and updating of data utilizing existing Web protocols. OData is a REST-based protocol for querying and updating data and is built on standardized technologies such as HTTP, Atom/XML, and JSON. It is different from other REST-based web services in that it provides a uniform way to describe both the data and the data model.

It is considered to be a flexible technology for enabling interoperability between disparate data sources, applications, services and clients

• The purpose of the Open Data protocol (hereafter referred to as OData) is to provide a REST-based protocol for CRUD-style operations (Create, Read, Update and Delete) against resources exposed as data services. A “data service” is an endpoint where there is data exposed from one or more “collections” each with zero or more “entries”, which consist of typed named-value pairs. OData is published by Microsoft under OASIS (Organization for the Advancement of Structured Information Standards) Standards so that anyone that wants to can build servers, clients or tools without royalties or restrictions.
