person mention

From IndieWeb

person mention is a homepage webmention sent to a person's homepage.


You should send person mentions whenever you post one of these so people can be notified that you've mentioned them!

You should accept person mentions of/to your site so you can find out when others have mentioned you!


How to person mention

Send a webmention as you usually would:

  • source: your post permalink
  • target: the person's homepage URL

If you're doing something beyond merely mentioning someone, e.g. inviting them to an event, or person-tagging them, then see these pages for how to add that markup:

How to receive person mentions

You should separate out webmentions to your homepage into a separate list on your site, perhaps even sending you notifications for each using your preferred notification mechanism.

How to distinguish person mentions

When you receive a person mention, it may mean something more, here's how you tell.

  • invitation: if the target link to your home page is a u-invitee link, then you've been invited to the event linked to by the in-reply-to of that h-entry
  • person-tag: someone tagged you in their (source) post, if the target link to your home page is a u-category link.
    • unless the containing h-entry has a u-tag-of link, in which case the source is merely tagging you in a different post, the post that the u-tag-of links to.
  • ...
  • otherwise it's just a mention.

Once you've distinguished different kinds of person mentions, you may want to:

  • display these differently (in abovementioned list on your site), e.g. with different icons, prose, clustering, and/or sorting than "plain" person mentions
  • send different notifications for (or maybe only send for some not for all) different kinds of person mentions
  • provide different UI on each in a list, e.g.
    • for person-tags, perhaps provide the option to request "untagging" ("untag-of" link?)
    • for invitations, provide RSVP buttons yes, no, maybe, save which could one-click create respective RSVP posts on your site and send webmentions accordingly (back to the invitation, and to the event as well).

IndieWeb Examples

Examples of IndieWeb sites that send and/or receive person mentions and do something visible (perhaps only to the site owner) with them.

Published mentions of people using @domain.tld syntax since around 2013-03-26, as evidenced in:

Ben Roberts

  • Ben Roberts displays all webmentions to his homepage url under "Recent Mentions" on the sidebar since YYYY-MM-DD(?)


Tantek Çelik started using @domain.tld syntax since at least 2017-12-11 paid in full via Venmo! Thanks for the @BlueStarDonuts! 🍩🍩🍩🍩

and added it to the CASSIS auto link function on 2017-12-13

Before that, Tantek Çelik had experimented in 2011 with the +Name syntax from Google+, in blog posts referring to people by full name and linking to their domain:

    • "One of the fun things about #IndieWeb notes & replies is that how we post is actively evolving! Like how should we @ someone?

      #socialMedia aliases (e.g. @Twitter) were obvious, with prior @-name usage on Flickr etc.

      Now, some have a domain, or an @-@ (pronounced at-at, yes, just like the abbreviation for Imperial All Terrain Armored Transport¹), or some have both.

      We can ask questions like why do we @-someone? What are the use-cases?
      * In a reply to a public post, clearly express that you’re speaking to that person
      * In a reply to a reply, that you’re speaking to everyone upthread (AKA a
      * When attributing something to someone (photo/post/cool thing by so-and-so), giving credit
      * Distinguish a person (or something that can be followed) from “just” a site
      * For all the above, notifying someone accordingly

      Some ideas:

      1. Ideally, if/when everyone has their own domain (where they receive Webmention notifications, and a feed you can follow), we can @-name their domain, which your auto-linker² should hyperlink accordingly, e.g.

      These all look close enough to social media aliases/names that they’re immediately recognizable as readable @-names, a good consideration when choosing a domain name.³

      2. As a fallback (e.g. for non-@-domain-auto-linking destinations) we can use someone’s plain domain (explicitly with https:), especially if their home page still has a stream or feed you can follow, or maybe if they don’t receive homepage Webmentions (yet), e.g.:

      3. Some folks with personal sites have (for now) created separate Mastodon accounts (or installed an instance on a subdomain), and for them, we can reference their @-@ parenthetically after their domain, like:
      * (, (, (

      Rather than using social media silo @-names (except when explicitly replying to a silo), I’m now experimenting with all three of these (1-3) instead, both to elevate people’s IndieWeb identities, and for Mastodon viewers, provide a convenient way to follow @-@ addresses.

      If someone’s homepage receives Webmentions, they will get notified when I @-mention them by domain.

      I recently implemented syntactic auto-linking of @-@ addresses like this:
      * -->
      with a special case for @-domain@-domain to just link to the domain, e.g.:
      * -->

      I also made a recent policy decision to auto-link all @-@ (and @-domain) mentions to https:, the reasoning being that identities on the web should be using https.
      * Testing in production here:, search for "auto_link("

      Some questions:
      * Does/do Mastodon (or other ActivityPub servers) notify people when you @-@ mention them in a post? How? Who’s responsible for that?
      * Will Bridgy Fed notify the servers (deliver to AP inboxes) of folks I merely @-@ mention (rather than explicit replies, reposts)? Should it?

      So many people are switching to using their personal domains to post (or at least a Mastodon account) that I no longer feel compelled to @-mention people’s Twitter handles in posts, which feels refreshing.

      Now the fun part is experimenting and figuring out what combination of @-domain, plain domain, or @-@ mentions looks good, makes sense to people, and sends notifications to people the way they want to receive them.
