rel

rel is short for "relationship" and an HTML 4.01 attribute on the a and link elements. The 'rel' attribute is used for several popular elemental microformats such as rel-nofollow, rel-license, rel-tag, and XFN. Popularity is noted as of 2005-12 per the Google study on markup use, in particular the use of link relationships, the <a> tag, and related page headers (which noted that "XFN [is] the most popular HTML metadata profile").
