This document represents a draft microformat specification. Although drafts are somewhat mature in the development process, the stability of this document cannot be guaranteed, and implementers should be prepared to keep abreast of future developments and changes. Watch this wiki page, or follow discussions on the #microformats Freenode IRC channel to stay up-to-date.

Abstract

Rel-Home is one of several MicroFormats. By adding rel="home" to a hyperlink, a page indicates that the destination of that hyperlink is the homepage of the site in which the current page appears. When the appropriate HTML Meta data profile is in use, the "home" type can be used alongside standard Link Types.

Example usage :

<head>
...
<link href="http://technorati.com" rel="home" />
...
</head>

The rel value may also appear wherever an anchor link may appear, e.g.

<body>
...
<a href="http://technorati.com" rel="home">Home</a>
...
</body>

the author indicates that the linked page is the homepage of the site.

The linked page SHOULD exist. Use of an absolute URI is recommended.

Scope

rel="home" is designed for site navigation purposes, as well as allowing some description of site structure to be derived from individual pages. Typical use might be in the archive pages of a weblog, pointing back to the front page.

XMDP profile

<dl class="profile">
 <dt id="rel">rel</dt>
 <dd><p>
   <a rel="help" href="http://www.w3.org/TR/html401/struct/links.html#adef-rel">
     HTML4 definition of the 'rel' attribute.</a>  
   Here is an additional value.</p>
  <dl>
   <dt id="home">home</dt>
   <dd>Indicates that the referred resource serves as the homepage, 
       of the site which includes the referring page.</dd>
  </dl>
 </dd>
</dl>

Examples in the Wild

This section is informative.

The following sites have implemented rel-home, and thus are a great place to start for anyone looking for examples "in the wild" to try parsing, indexing, organizing etc. If your site is marked up with rel-home, feel free to add it to the bottom of this list. Once the list grows too big, we'll make a separate wiki page.

Implementations

This section is informative. The following implementations have been developed which either generate or parse rel-home links.

Ed. : links to follow

Normative References

Informative References

Ed. : need to track down previous discussions, e.g. re. Opera

Brainstorming

If this section gets too large (and is not just incorporated into the draft), it can be moved to rel-home-brainstorming.

use with rel-alternate

Many blog post permalink pages have feed autodiscovery links that link from the permalink page via a link element to the feed for the site using just rel="alternate".

This is semantically incorrect as the feed is an alternate for the *site*, not the permalink page.

rel="home" could (and should) be used with rel-alternate to link from a permalink page to the feed for the site (home page). e.g. on tantek.com permalink pages (simplified)

<link rel="home alternate" type="application/atom+xml" href="../updates.atom" />

This way a feed reader / indexer / search engine knows that the link represents an alternate for the home page relative to the current page, not an alternate for the page itself.

There is one known exception which is that if the alternate link is a feed to the comments on that post, then that would make sense as an actual alternate representation of the post permalink page.

Discussion of this brainstorm:

  • +1 Kevin Marks though need to check behaviour in browsers that support rel-home on link
