My h-card as of a few minutes ago
You did what now?
I updated my home page h-card for the IndieWeb.
h-card is a microformats2 vocabulary to describe people and organizations. I added terms from that vocabulary as HTML classes to elements of a profile section on the front page.
It helps identify me for other folks on the IndieWeb. Some have written tools and services that speak h-card. Mostly, the h-card vocabulary gives me a convenient way to organize my biographical details for visitors to this site.
What are you talking about?
Describing yourself in a useful way presents a challenge, especially online. Prose has the greatest clarity for human readers — assuming they know the language you write in. Social networks give you a profile page with slots for important details — assuming they include fields for the details you consider important.
We can use h-card to identify ourselves and others in the IndieWeb. Officially, it’s a collection of properties for detailing individuals and groups of people. Informally, it’s also the descriptions we create with those properties. I used the h-card vocabulary to create a profile. That profile included details that I consider important.
A minimal h-card
I have a name that I commonly use both online and off.
Really that’s my “good enough” name. It’s not the full legal name on my social security card. Most of my friends don’t use it for me unless they’re trying to tell me apart from all the other people named Brian. Now is not the time for Falsehoods Programmers Believe About Names, but know that h-card handles this dilemma better than many solutions.
In a stroke of good fortune, this name conforms to local convention. A surname disambiguates my family from others. A given name disambiguates me from other members of my family.
Some clarity might help people unfamiliar with my local naming convention, though.
Wrap the name in any element, give that element an
h-card class, and it’s an h-card!
Now we’re definitely talking about a person. Or maybe an organization. We’re talking about a named entity. We know that much.
But where can we get useful information about this entity? Over in Twitter we say
@brianwisti and it points to my Twitter profile. What’s an IndieWeb equivalent?
Since any element can hold an h-card, replace the
<span> with a link to my site.
This tells anyone that Brian Wisti — that’s me — considers
https://randomgeekery.org — that’s here, or rather here — the center of his online identity.
This is sufficient to uniquely identify me online. It’s the form I’d use when referencing someone else online. I could even get away with using that form for my own card.
A profile card
Where do I put my card?
I use my site’s root URL, but not everyone identifies so closely with their Web site. Put your h-card on what you consider your profile page. If your profile page is
yoursite.info/yourname, then that’s where you put the h-card.
Just make sure the location matches the URL specified in the card itself!
This abbreviated form contains more assumptions than I like. We can assume that “Brian Wisti” is a name. The format calls that an implied property. There’s honestly nothing wrong with that. I spend enough time in Python that I prefer explicit to implicit when practical.
microformats2 prefixes confuse me, but they have a consistent pattern and rules for parsing.
Rules for microformats2 properties
|What it’s called
|What we expect them to describe
|root class name
|Details about a person, post, event, etc.
|plain text property
|Names, bios, descriptive text
|where to find sites, images, or other resources
|Calendar entries for events, birthdays, anniversaries
|embedded markup property
|entire document subtrees
Now we can see that the link is an h-card, the link is a home page, and the contents are a name. This says exactly the same thing as the previous version. Do the extra classes add any real value here?
For a parser, maybe. For a human reader, no. I can clarify things for this human writer, though.
I still haven’t added much in the way of useful information. This structure shows me where I can add other elements, and that’s progress. Remember that microformats focuses on making life easier for the people using them. It’s just that some of us are a little odd.
Let’s add some stuff. Profile cards usually have an image and a bio, right?
microformats clarify intent — once you know them. I might have a dozen photos in an h-card. Assigning
u-photo lets me say “This one matters when talking about me.” Regardless of how many paragraphs of text I put in my card, we know that the
p-note text is describing me.
Okay, that’s actually worth looking at. There’s some CSS styling, but I won’t get into that. Just spend a few days on CSS-Tricks and have fun.
Linking your card to other services
https://randomgeekery.org may be my home page, but it’s not the only place folks find me. I routinely post on Mastodon and Twitter. I sometimes peek my head in to see what’s new on Github and LinkedIn. h-card can help integrate with those as well.
Add them as rel-me links!
The a element’s
rel attribute describes a relationship between your page and the link. Use me to tell people that this link is also about you. It’s a way to consolidate the online identities you want connected.
My hackers.town Mastodon profile has a link to this site. The site includes a rel-me link to my hackers.town profile. Mastodon users looking at my profile see a verified connection between each.
That’s how you get a verified check on Mastodon sites
RelMeAuth takes advantage of the relation between your site and OAuth providers. If IndieWeb authenticators like IndieLogin and IndieAuth see rel-me links to known providers, they let you verify your site and yourself through those providers.
I can use my Twitter or Github accounts to authenticate
Specifying my main page
New problem. My h-card now includes several
u-url links that are all me. Which one is the real me? I make that link the
Add some details
This is a reasonable stopping point for a profile h-card. It names, shows, and describes me, including links to find me on assorted social networks. But I’d like to add some more information. Using microformats, of course.
Where do I live?
I live in the city of Seattle. My
p-note already says so. But again: it might be useful to highlight it as a location. Several h-card options describe locations in all the detail you could want — right down to latitude and longitude. But no. I’ll use
p-locality and maybe revisit later if I want more specificity.
What interests me?
We all have hobbies, right? With
p-category I list things we could discuss. Let’s make links out of some that I’ve posted about.
What should you call me?
What about pronouns? That’s one way to specify I’m a person instead of an organization.
Maybe I could skip it. My picture is beardy and my name is masculine. Obviously I’m male. Then again, what’s obvious to me may be less so to someone else. Explicit versus implicit.
Do I just tag myself “male” and move on? I could use
p-gender-identity. That sounds unusably clunky to me. I’m unconcerned what folks think about my chromosomes. I just want them to know it’s okay to call me “he”.
That’s one of my favorite things about h-cards and microformats. You can opt-in to the pieces you care about, and leave the rest alone.
I thought about Jamie Tanna’s example:
I like it, but that’s more markup than I want. What about using the link to Pronoun Island I used a moment ago? Let me look over the microformats pronouns brainstorming and come up with something I like.
u-pronoun isn’t an official property. Even so, it follows the microformats2 style by using the
u- prefix to indicate a link.
Okay so what do I have now?
Now my h-card includes all the information I care about. Time to make sure I put it together correctly! h-cards exist in the context of other documents, like my Web page. Validation is less formal: mainly, check that microformats2-aware parsers find your information.
The mf2 validator shows you the results of parsing either a URL or text provided by you, which makes it useful for double-checking your h-card while building it.
The mv2 validator produces JSON from your h-card
The IndieWebify.me validator styles its report for readability. It even offers suggestions for common details you could add.
It doesn’t accept raw HTML, though. You need to provide a URL, which is less handy for an in-development h-card.
What about some other h-cards?
I’m pretty much done, other than a plan to incorporate Fork Awesome for me rel-me links. But that’s a topic for another day, if ever.
Do you want to see more h-cards out in the world? The IndieWeb wiki maintains a list of example h-cards, including links to other collections.
Most h-cards I see are small, but they don’t have to be. Martijn van der Ven’a h-card fills an entire page. Have fun coming up with something that works for you!
