By
using author element, you can specify the author of the feed (or) entry.
Rules applied to
author elements for entries
If
an atom:entry element does not contain atom:author elements, then the
atom:author elements of the contained atom:source element are considered to
apply.
In
an Atom Feed Document, the atom:author elements of the containing atom:feed element
are considered to apply to the entry if there are no atom:author elements in
the locations described above.
Example
Feed
level author element
<feed xmlns="http://www.w3.org/2005/Atom"> <author> <name>hari krishna</name> <email>noreply@blogger.com</email> <uri>https://self-learning-java-tutorial.blogspot.com</uri> </author> ..... ..... </feed>
