Atom was created because of the standards issues that have plagued RSS over time. It was born in 2003.
There are two versions, Atom 0.3 and Atom 1.0. It is far more standardized but also more complicated

simpler by most metrics, and that is the format demonstrated here when you create a web feed. To syn-
dicate feeds, however, you will employ the use of a PHP library called SimplePie, which reads
sions of RSS and Atom feeds transparently.
A typical RSS 2.0 feed might look like this:
