What is Atom XML?

Question

I am working in ODATA Service in .net. I heard that the ODATA service returns both ATOM XML and JSON. I am not sure about ATOM XML.

Can someone please explain what ATOM XML is with an example?

It is XML based file format http://en.wikipedia.org/wiki/Atom_%28standard%29 — Madhur Ahuja, Aug 28 '14 at 04:00
It's simple enough to check [Wikipedia](http://en.wikipedia.org/wiki/Atom_%28standard%29) or search the web for _Atom XML_ to find lots of other explanations. — Ted Hopp, Aug 28 '14 at 04:00
What is [Google](http://www.google.com) or [Wikipedia](http://en.wikipedia.org/wiki/Atom_%28standard%29)? SO should be your **last resort**, after exhausting your efforts to find an answer, not the very first. — Ken White, Aug 28 '14 at 04:01

Atom is an XML-based file format used to syndicate content. Developed as an alternative to RSS 2.0, it lies within an XML-namespace. An example of an Atom 1.0 feed is:

<?xml version="1.0" encoding="utf-8"?>

<feed xmlns="http://www.w3.org/2005/Atom">

<title>Example Feed</title>
<subtitle>A subtitle.</subtitle>
<link href="http://example.org/feed/" rel="self" />
<link href="http://example.org/" />
<id>urn:uuid:60a76c80-d399-11d9-b91C-0003939e0af6</id>
