Using rel=me on a hyperlink indicates that its destination represents the same person or entity as the current page, which is a key building-block of web-sign-in and IndieAuth. uses rel=me links to enable signing into websites such as

See the rel-me specification for more details.



You should add rel="me" to hyperlinks on your home page to your other profiles to enable web-sign-in and IndieAuth using your domain as your identity, rather than depending on silo sign-in methods,

It also allows distributed verification - proof that an account on one site is under the control of the same person as another site. For example, Huffduffer will follow rel="me" links to show your connected social accounts without you having to enter them individually.

Should my rel-me be inside my hCard?

A: Another way of restating that is, should your rel="me" hyperlink also have class="u-url" and be inside your h-card? And the answer is:

A2: Yes it should, because it will enhance your h-card, and make it into a representative h-card, but it is not necessary for rel=me to work with indieauth.

Follow-up Q: This on my blog but it’s not actually what I use for my main indieauth, should it still be setup like that?

Follow-up A: Because it is on your blog, you're likely using that URL as your p-author h-card URL. Thus making sure it has a good representative h-card is a good idea

Can I add rel-me to non-profile pages?

You should not add rel-"me" to pages that doesn't represent the same user as the profile the rel-"me" links to.

One should only add rel-"me" to pages that is seen as representing the same user as the profile it links to. Such pages can be the home page of a single user site or the author pages of a multi user site.

rel-author is often what one wants instead when linking to a profile page from non-profile pages.


  • PHP indieweb/rel-me package has functions for getting rel=me URLs on a site, securely deriving profile URLs and securely matching silo backlinking URLs against profile URLs
  • Ruby relparser.rb (part of IndieAuth) contains functions for doing the same sort of stuff
  • Python (part of Ronkyuu) contains functions to discover rel=me URLs on a site, generate normative URLs for both profile and resource URLs and to confirm that a resource URL is authoritative for a given profile URL.

Connecting the dots between rel=me and relmeauth

This is my current interpretation - so people can correct and critique it rather than assert any truthiness to this.

rel=me is intended to mean that the destination represents "the same person as" the current page.

However, it also serves a dual purpose when used for RelMeAuth based authorization. Here, a rel=me link really wants to mean the destination "can claim control over" the current page. You could instead pretend there's a "rel=is-controlled-by" tag to distinguish the two contexts.

Why does this distinction matter?

A page such as cannot (legitimately) claim a rel=me link to Clearly, the site "" does not represent a "person who is the same as"

However, the root domain on every website does control all its sub pages, so in fact, has an implicit "rel=is-controlled-by" to, but it does not have a rel=me link to

This distinction matters when finding rel=me closures in the two contexts of identity consolidation and relmeauth based authorization.

To make this concrete, let's assume we have these three pages, with these rel=me links on them. [rel=me] -> {} [rel=me] -> {} [rel=me] -> {}

Context 1: Consolidating Identities

Given a page, find me all the pages who are "the same person as" the current page.

The approach is to recursively follow all the rel=me links from the starting page, and return only that subset which is within any loop of rel=me links that include the starting page.

This is so that only a group of mutually verifying pages are returned, or anyone could simply claim they were by putting a rel=me link on their page.

If we started from, we'd get back


as the pages who "are the same person as"

And If we started from, we'd get back just


Context 2: relmeauth based login

Given an page, find me all the pages "who can control" the current page. The "current page" is used as the username, and one of the controlling pages is used to login the user, say through OAuth.

In principle (though implementations don't necessarily do this) the approach is still similar, but now there is an implicit assumption that any subpage of a domain is controlled by the bare domain.

In particular, the set of all pages "who can control" is


because of the implied link that is-controlled-by

Edge Cases

Edge cases are questions or issues brought up typically by only one (or a small number) of people, and in practice affect very few people. We document them anyway in the hopes of helping out those few, yet apart from the broader #FAQ, keeping the FAQ focused on frequently asked questions (applicable to more people in general).

What About RDFa Problems

If you use RDFa and are having problems, note that RDFa redefines 'rel' attribute processing that is incompatible with the HTML(5) standards thus rel=me may produce unexpected results inside RDFa.[1]

There is a solution available in RDFa WG mail archives

Any non-CURIE (e.g. "me") will be ignored in a @rel if there is a @property attribute in the same element. Here is what I recommend to use, which simplifies your markup as you don't need to repeat the mailto:. Drop the @rel from the ul, and use something like this:
<ul vocab="">
    <a rel="me" property="contactPoint" typeof="ContactPoint" href="mailto:"><span
property="name">email (smtp)</span></a>
