Whois & Analysis for odata.org

In computing, Open Data Protocol (OData) is an open protocol which allows the creation and consumption of queryable and interoperable RESTful APIs in a simple and standard way.

Microsoft initiated OData in 2007.

Versions 1.0, 2.0, and 3.0 are released under the Microsoft Open Specification Promise.

Version 4.0 was standardized at OASIS, with a release in March 2014.

In April 2015 OASIS submitted OData v4 and OData JSON Format v4 to ISO/IEC JTC 1 for approval as an international standard.

Representational state transfer (REST) or RESTful Web services are one way of providing interoperability between computer systems on the Internet.

REST-compliant Web services allow requesting systems to access and manipulate textual representations of Web resources using a uniform and predefined set of stateless operations.

Other forms of Web service exist, which expose their own arbitrary sets of operations such as WSDL and SOAP.

"Web resources" were first defined on the World Wide Web as documents or files identified by their URLs, but today they have a much more generic and abstract definition encompassing every thing or entity that can be identified, named, addressed or handled, in any way whatsoever, on the Web.

In a RESTful Web service, requests made to a resource's URI will elicit a response that may be in XML, HTML, JSON or some other defined format.

The response may confirm that some alteration has been made to the stored resource, and it may provide hypertext links to other related resources or collections of resources.

Using HTTP, as is most common, the kind of operations available include those predefined by the HTTP verbs GET, POST, PUT, DELETE and so on.

By making use of a stateless protocol and standard operations, REST systems aim for fast performance, reliability, and the ability to grow, by re-using components that can be managed and updated without affecting the system as a whole, even while it is running.

An open standard is a standard that is publicly available and has various rights to use associated with it, and may also have various properties of how it was designed (e.g. open process).

There is no single definition and interpretations vary with usage.

Interoperability is a characteristic of a product or system, whose interfaces are completely understood, to work with other products or systems, present or future, in either implementation or access, without any restrictions.
