h-card is a simple, open format for publishing people and organisations on the web. h-card is one of several open microformat draft standards suitable for embedding data in HTML/HTML5.

h-card is the microformats2 update to hCard.

Example

Here is a simple minimal person example:

<a class="h-card" href="http://example.com">Joe Bloggs</a>

And a slightly more complete example:

<p class="h-card">
  <img class="u-photo" href="http://example.org/photo.png" />
  <a class="p-name u-url" href="http://example.org">Joe Bloggs</a>
  <a class="u-email" href="mailto:joebloggs@example.com">joebloggs@example.com</a>
  <p class="p-adr h-adr">
    <span class="p-street-address">17 Austerstræti</span>
    <span class="p-locality">Reykjavík</span>
    <span class="p-country-name">Iceland</span>
  </p>
</p>

Get started

The class h-card is a root class name that indicates the presence of an h-card.

For minimal examples where at most p-name, u-url and u-photo are required (such as the first given above), only the root class name is needed — see implied properties.

For more complex examples, the root class name must be placed on an element which encloses all the desired properties, and then the properties themselves marked up using the classnames given below.

See microformats-2-parsing to learn more about property classnames.

Properties

h-card properties, inside an element with class h-card:

• p-name - The full/formatted name of the person or organisation
• p-honorific-prefix - e.g. Mrs., Mr. or Dr.
• p-given-name - given (often first) name
• p-additional-name - other/middle name
• p-family-name - family (often last) name
• p-sort-string - string to sort by
• p-honorific-suffix - e.g. Ph.D, Esq.
• p-nickname - nickname/alias/handle
• u-email - email address
• u-logo
• u-photo
• u-url - home page
• u-uid - unique identifier
• p-category - category/tag
• p-adr - postal address, optionally a nested
  Main article: h-adr
• p-post-office-box
• p-extended-address
• p-street-address - street number + name

• p-region - state/county/province
• p-postal-code - postal code, e.g. US ZIP
• p-country-name - country name
• p-label
• p-geo or u-geo, optionally a nested
  Main article: h-geo
• p-latitude - decimal latitude

• p-note - additional notes
• dt-bday - birth date
• u-key - cryptographic public key e.g. SSH or GPG

• dt-anniversary

Status

h-card is a microformats.org draft specification. Public discussion on h-card takes place on h-card-feedback, the #microformats irc channel on irc.freenode.net, and microformats-new mailing list.

h-card is ready to use and implemented in the wild, but for backwards compatibility you should also mark h-cards up as classic hCards.

Property Details

(stub, to be expanded)

p-adr and its associated postal address properties can optionally use h-adr, for example:

<p class="p-adr h-adr">
  <span class="p-street-address">17 Austerstræti</span>
  <span class="p-locality">Reykjavík</span>
  <span class="p-country-name">Iceland</span>
</p>

Reserved properties (not used much, if at all, in practice):

• p-organization-name
• p-organization-unit
• p-tz
• dt-rev

Note: use of 'value' within 'tel' should be automatically handled by the support of the value-class-pattern. And for now, the 'type' subproperty of 'tel' is dropped/ignored. If there is demonstrable documented need for additional tel types (e.g. fax), we can introduce new flat properties as needed (e.g. p-tel-fax).

Examples in the wild

Real world in the wild examples:

• ... add uses of h-card you see in the wild here.
• W3Conf 2013 uses h-card for all the event speakers and notable attendees. The h-cards make particularly good use of implied name, url, and photo properties.
• SemPress is a WordPress theme that supports h-card, h-feed/h-entry and h-as-*
• The Pastry Box Project use h-card markup on their homepage and individual thoughts pages
• Tom Morris uses h-card and XFN to markup his blogroll.
• Aaron Parecki uses h-card to markup both authorship and references to people in his notes permalinks, e.g. 2012/230/reply/1.
• Tantek Çelik uses h-card on his home page as well as within h-entrys on permalink pages to indicate authorship.
• Barnaby Walters uses h-card on his home page, as well as within h-entries for notes and articles, both to indicate authorship and also when mentioning people within the body of the notes.
• microformats.org at 7 years presentation with and h-card markup for people and organizations.
• Rise of the Indie Web hCards (from Personal Democracy Forum 2012 #pdf12 #pdf2012) has microformats-2 h-card markup
• WebMaker by Mozilla has microformats-2 h-card on event search (e.g. search near Portland Oregon) and event pages (e.g. IndieWebCamp 2012).[1]
• WebFWD by Mozilla has microformats-2 h-card markup on experts and team pages
• IndieWebCamp has microformats-2 h-event markup with nested h-cards for the organizers and the location.
• Mozilla Events page has microformats-2 h-event markup with attendees marked up with h-card.

Backward Compatibility

Publisher Compatibility

For backward compatibility, you may wish to use classic hCard classnames in addition to the more future-proof h-card properties, for example:

<span class="p-name fn n">Joe Bloggs</span>

Parser Compatibility

Microformats parsers SHOULD detect the following root class name and property names. A microformats2 parser may use existing microformats parsers to extract these properties. If an "h-card" is found, don't look for a "vcard" on the same element.

Compat. root class name: vcard
Properties: (parsed as p- plain text unless otherwise specified)

• fn - parse as p-name
• honorific-prefix
• given-name
• additional-name
• family-name
• honorific-suffix
• nickname
• email - parse as u-
• logo - parse as u-
• photo - parse as u-
• url - parse as u-
• uid - parse as u-
• category
• adr - parse as p-adr h-adr including compat root class adr
• extended-address
• street-address
• locality
• region
• postal-code
• country-name
• label
• geo - parse as p-geo h-geo including compat root class geo
• latitude
• longitude
• tel
• note
• bday - parse as dt-
• key - parse as u-
• org
• organization-name
• organization-unit
• title - parse as p-job-title
• role

Reserved: (backward compat properties that parsers MAY implement, if they do, they MUST implement in this way:

• tz
• rev - parse as dt-

Background

This work is based on the existing hCard and vcard specifications.
