RSS - Comparison With Atom

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:

    Certainly there is not the fight recorded in Concord history, at least, if in the history of America, that will bear a moment’s comparison with this, whether for the numbers engaged in it, or for the patriotism and heroism displayed.
    Henry David Thoreau (1817–1862)

    Intolerance respecting other people’s religion is toleration itself in comparison with intolerance respecting other people’s art.
    Wallace Stevens (1879–1955)

    He bends to the order of the seasons, the weather, the soils and crops, as the sails of a ship bend to the wind. He represents continuous hard labor, year in, year out, and small gains. He is a slow person, timed to Nature, and not to city watches. He takes the pace of seasons, plants and chemistry. Nature never hurries: atom by atom, little by little, she achieves her work.
    Ralph Waldo Emerson (1803–1882)
