Comparison With Atom
Both RSS and Atom are widely supported in all major consumer feed readers. RSS has gained widespread distribution through feed reader implementations earlier than Atom, which led to higher popularity. However, Atom has several advantages over RSS, such as less restrictive licensing, IANA registered MIME type, an XML namespace, support for relative URIs, and Relax NG support. Technically, Atom should be considered the more advanced syndication format between the two.
The following table summarizes those RSS elements that have their equivalents in Atom.

Famous quotes containing the words comparison with, comparison and/or atom:
“He was a superior man. He did not value his bodily life in comparison with ideal things. He did not recognize unjust human laws, but resisted them as he was bid. For once we are lifted out of the trivialness and dust of politics into the region of truth and manhood.”
—Henry David Thoreau (1817–1862)
“From top to bottom of the ladder, greed is aroused without knowing where to find ultimate foothold. Nothing can calm it, since its goal is far beyond all it can attain. Reality seems valueless by comparison with the dreams of fevered imaginations; reality is therefore abandoned.”
—Emile Durkheim (1858–1917)
“The atom bombs are piling up in the factories, the police are prowling through the cities, the lies are streaming from the loudspeakers, but the earth is still going round the sun.”
—George Orwell (1903–1950)
