rel="me"
- short URL
- http://ufs.cc/w/relme
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://github.com/tantek" rel="me">@t</a>
And his GitHub profile itself has (markup simplified)
<a href="https://tantek.com/" rel="me">https://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.

TO BE UPDATED
The sections below this need to be updated (e.g. links verified, and deadlinks replaced with Internet Archive versions)
implementations
Notable Sites:
- App.net implements rel-me for officially connecting your domain to your app.net account, as well as publishing rel-me on your site.
Services:
- IndieAuth is perhaps the most comprehensive rel-me implementation, using it to implement RelMeAuth and a superset of web-sign-in that is focused on independent websites.
- Social Links Wordpress plugin - supports rel-me links to other services
- About Me plugin (on github) - supports creation of an About Me page with rel-me links to other profiles.
past implementations
- Google used reciprocal rel=me links for domain verification, which it also used for independent site rel-author support.
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.
Current requests:
- Gittip: Add "website" profile field #2477 - requested 2014-06-07 by Aaron Parecki.
