Subscribing to Content with Web Slices

Today, many Web sites provide content updates through Really Simple Syndication (RSS) news feeds. This requires a Web site to duplicate some content as a special XML file, called a feed, that a news reader application can download and check for updates. In contrast, a Web Slice enables users to subscribe to content directly within a Web page; a separate feed file is not required. Users monitor content changes and view the updated portion of the Web page directly from the Favorites bar (the improved Links toolbar) of Windows Internet Explorer.

Web Slice Format Specification - Version 0.9

A Web Slice allows users to subscribe to a portion of a Web page. The Web Slice format consists of the minimum HTML annotations necessary to enable the publication and consumption of a mutable item on a Web page. Web publishers can use this format in conjunction with properties from hAtom Microformat  to make portions of a Web page subscribe-able.
