Abstract

relEnclosure is one of several MicroFormats. By adding rel="enclosure" to a hyperlink, a page indicates that the destination of that hyperlink is intended to be downloaded and cached. E.g. with the following hyperlink:

<a href="http://homepage.mac.com/kevinmarks/wwdc2005.mov" rel="enclosure">WWDC 2005 Keynote with chapters</a>

the author indicates that the movie should be downloaded.

Multiple Enclosures

Multiple such rel="enclosure" hyperlinks indicate that several media items should be downloaded.

4.2.7.2  The "rel" Attribute
  4.  The value "enclosure" signifies that the IRI in the value of the
      href attribute identifies a related resource which is potentially
      large in size and might require special handling.  For atom:link
      elements with rel="enclosure", the length attribute SHOULD be
      provided.
