A syndication feed introduced in Internet Explorer 8 (IE 8). It lets a user subscribe to a part of a Web page that periodically changes and that has been coded as a Web Slice. When the change occurs in that Web Slice, IE 8 alerts the user. Although an RSS or Atom feed can be converted into a Web Slice, Slices were designed for even single items that change, such as an auction price. See hAtom and syndication format.
