`rel="me"` HTML attribute value

The me keyword for the rel attribute of the <link> and <a> elements indicates that the current resource is represented by the linked party. The me value was introduced in the XHTML Friends Network (XFN) specification.

<link rel="me" href="example.com" />

The rel="me" attribute is used in RelMeAuth and Web sign in specifications as a way to enable a person to identify themselves to a web service using their domain name or a particular URL.

Browser compatibility is irrelevant because rel="me" is used by web services and not by browsers.
