XFN - The XHTML Friends Network 1.1 introduced the "me" rel value which is used to indicate profile equivalence and for identity-consolidation.

example

rel="me" is used on hyperlinks from one page about a person to other pages about that same person.

For example, Tantek's home page has (markup simplified)

<a href="https://twitter.com/t" rel="me">@t</a>

And his Twitter profile itself has (markup simplified)

<a href="http://tantek.com/" rel="me">http://tantek.com/</a>

Thus establishing a bi-directional rel-me link and confirming that the two URLs represent the same person.

Publishers can use the XFN creator form to create rel-me hyperlinks.

domain verification

rel=me is the standard way to check that a website belongs to a user on a 3rd party site.

  • read a user's website that they entered into their 3rd party site profile
  • check for a rel=me hyperlink from their website to their 3rd party site profile
  • if such a rel=me hyperlink is found, then the user has proven that they control that personal website sufficient to put a link back to their 3rd party site profile, and thus domain verification succeeds.

If you're the implementer of such a 3rd party site with user profiles, implement the above to implement a personal website domain verification feature.

rel-me-auth

RelMeAuth is a proposed open standard for using rel="me" links to profiles on oauth supporting services to authenticate via either those profiles or your own site.

In short it is a combination of domain verification as documented above, and OAuth authorization on the 3rd party site that the user's domain links to.

Read more about how to implement RelMeAuth and Web sign-in.
