Abstract

Rel-Directory is one of several microformats. By adding rel="directory" to a hyperlink, a page indicates that the destination of that hyperlink is a directory listing for the current page.

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

the author indicates that the page http://dmoz.org/Computers/Internet/ 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), this

<a href="http://odeo.com/tag/arts/" rel="tag directory">arts</a>

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.
