hCard properties and how to use them.

Place the following into the <head> of your document: 

<link rel="profile" href="http://microformats.org/profile/hcard">

See rel-profile for details.

Key

Based on Perl's standard quantifiers:

bold {1} MUST be present exactly once
italic* OPTIONAL, and MAY occur more than once
+ MUST be present, and MAY occur more than once
? OPTIONAL, but MUST NOT occur more than once
[square brackets] list of common values
(parentheses) data format
# comment
! awaiting documentation
pref preferred
dom domestic
intl international
cell mobile

Notes

  • The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119.
  • URL in vCard becomes <a class="url" href=...>...</a> inside the element with class vcard in hCard.
  • Similarly, EMAIL in vCard becomes <a class="email" href="mailto:...">...</a>
  • FN is an abbreviation of "formatted name".
  • PHOTO in vCard becomes <img class="photo" src=... alt="Photo of ..." /> or <object class="photo" data=... type=...>Photo of ...</object>
  • UID in vCard simply becomes another semantic applied to a specific URL (or EMAIL) for an hCard.
  • Compare TITLE of "Wing Commander" with ROLE of "pilot".

Adr

  • At least one child-property MUST be present in adr.
  • If an adr-child (e.g street-address) is present it will ONLY be considered part of the adr data IF it is inside an adr.
  • FAQ: "why 'adr'?"

Geo

  • Coordinates MUST use the datum of WGS84.
  • If latitude is present, so MUST be longitude, and vice versa.
  • Coordinates MAY be combined a single <abbr> element; then the latitude and longitude MUST be separated by a semicolon in the title attribute and latitude MUST be first:
<abbr class="geo" title="37.386013;-122.082932">home</abbr>

Deprecated

profile attribute

Previously this cheatsheet advised adding a profile attribute to the <head> like this: 

<head profile="http://www.w3.org/2006/03/hcard" />

This technique is valid for HTML4.x and XHTML1.x, however this is invalid for HTML5, thus authors are advised to use <link rel=profile ...> instead as described above See hCard:Profile for more information.

The hCard specification is a work in progress. As additional aspects are discussed, understood, and written, they will be added. These thoughts, issues, and questions are kept in separate pages.
