== Abstract ==
Rel-Directory is one of several [[microformats]]. By adding '<code>directory</code>' to the <code>rel</code> attribute of a hyperlink, a page indicates that the destination of the hyperlink is a directory listing containing an entry for the current page.

<pre><nowiki><a rel="directory" href="http://dmoz.org/Computers/Internet/">Computers/Internet</a></nowiki></pre>

the author indicates that the page <code>http://dmoz.org/Computers/Internet/</code> is a directory listing for the referring page.

This assertion will typically apply to just the referring page, though it may in some cases refer to a larger work, such as a blog or podcast.

Additionally, in the case that the directory page is a taggable url (follows the [[rel-tag]] microformat), these

<pre><nowiki>
<a rel="tag directory" href="http://odeo.com/tag/arts/">arts</a>
<a rel="tag directory" href="http://technorati.com/blogs/evolution">evolution</a>
</nowiki></pre>

can be used to show that the referred page is both a directory listing and a tag for the current page.

== Scope ==
[[rel-directory]] is specifically designed for building a directory in a distributed manner and for making links to any directory listing explicit.

== XMDP profile ==
<pre><nowiki>
<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="directory">directory</dt>
<dd>Indicates that the referred resource serves as a directory listing for the referring page.</dd>
</dl>
</dd>
</dl>
</nowiki></pre>

== Implementations ==
This section is '''informative'''. The following implementations have been developed which either generate or parse rel-directory links. If you have a rel-directory implementation, feel free to add it to the top of this list. Once the list grows too big, we'll make a separate wiki page.

* [http://technorati.com/blogs/ Technorati Blog Finder] is a blog directory that is organized and constructed by bloggers who themselves choose which categories their blog belongs in, using either a user interface, or by simply using a rel-directory tag link from their blog to the page for a particular category in a directory. See [http://technorati.com/help/blogfinder.html Technorati Blog Finder Help] for more info.
