XFN 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.

implementations

Notable Sites:

  • Google uses reciprocal rel=me links for domain verification, which it also uses for independent site rel-author support.
  • App.net implements rel-me for officially connecting your domain to your app.net account, as well as publishing rel-me on your site.

WordPress plugins:

advocacy

Advocating rel=me support can be done a few ways, if a site has:

  • user profiles but no "website" field - ask them to add a "website" field and mark it up with rel=me.
  • a "website" field on profiles - ask it to support publishing rel=me
  • a notion of "verification" or "verified" profiles - ask it to do so via confirming reciprocal rel=me
  • login/sign-in - ask it to support RelMeAuth with a Web sign-in user interface.
