<h1>hCard</h1>

hCard is a simple, open, distributed contact information format for people, companies, and organizations, which is suitable for embedding in (X)HTML, Atom, RSS, and arbitrary XML. hCard is a 1:1 representation of the vCard standard ([http://www.ietf.org/rfc/rfc2426.txt RFC2426]) in XHTML, one of several open [[microformats|microformat]] standards.

=== Inspiration and Acknowledgments ===
Thanks to: my good friend [http://vadim.com/ Vadim] who introduced me to vCard ''many'' years ago, and if I'd only paid more attention then, perhaps I could have helped a lot of people avoid wasting a lot of time reinventing various standards wheels.

== Introduction ==
The vCard standard ([http://www.ietf.org/rfc/rfc2426.txt RFC2426]), has been broadly interoperably implemented (e.g. Apple's "Address Book" application built into MacOSX).

In addition, many bloggers identify themselves by name and discuss their friends and family. With just a tad bit of structure, bloggers can discuss people in their blog(s) in such a way that spiders and other aggregators can retrieve this information, automatically convert them to vCards, and use them in any vCard application or service.

This specification introduces the '''hCard''' format, which is a 1:1 representation of the aforementioned vCard standard, in semantic XHTML. Bloggers can both embed vCards directly in their web pages, and style them with CSS to make them appear as desired. In addition, hCard enables applications to retrieve information about such vCards directly from web pages without having to reference a separate file.

Use the [http://microformats.org/code/hcard/creator hCard creator], copy the HTML code it generates to your blog or website to publish your contact info.

== Semantic XHTML Design Principles ==
{{semantic-xhtml-design-principles}}

== Format ==
=== In General ===
The vCard standard ([http://www.ietf.org/rfc/rfc2426.txt RFC2426]) forms the basis of hCard.

The basic format of hCard is to use vCard object/property names in lower-case for class names, and to map the nesting of vCard objects directly into nested XHTML elements.

=== More Semantic Equivalents ===
However, for some properties there is a more semantic equivalent, and therefore they get special treatment, e.g.:
* <code>URL</code> in vCard becomes <code><a class="url" href="...">...</a></code> inside the element with <code>class="vcard"</code> in hCard.
* Similarly, <code>EMAIL</code> in vCard becomes <code><nowiki><a class="email" href="mailto:...">...</a></nowiki></code>
* <code>PHOTO</code> in vCard becomes <code><img class="photo" src="..." alt="Photo of ..." /></code>

=== Singular vs. Multivalued Properties ===

For properties which are singular (e.g. "N" and "FN"), the first descendant element with that class should take effect, any others being ignored.

For properties which can be plural (e.g. "TEL"), each class instance should create a instance of that property.

==== Plural Properties Singularized ====

Since plural property names become their singular equivalents, even if the original plural property permitted only a single value with multiple components, those multiple components are represented each with their own singularly named property and the the property is effectively multivalued and subject to the above treatment of multivalued properties.

=== Human vs. Machine readable ===

If an <code><abbr></code> element is used for a property, then the '<code>title</code>' attribute of the <code><abbr></code> element is the value of the property, instead of the contents of the element, which instead provide a human presentable version of the value.

Similarly, if an <code><img></code> element is used for one or more properties, it must be treated as follows:
# For the "PHOTO" property and any other property that takes a URL as its value, the <code>src="..."</code> attribute provides the property value.
# For other properties, the <code><img></code> element's '<code>alt</code>' attribute is the value of the property.

=== Value excerpting ===

Sometimes only part of an element which is the equivalent for a property should be used for the value of the property. This typically occurs when a property has a subtype, like TEL. For this purpose, the special class name "<code>value</code>" is introduced to excerpt out the subset of the element that is the value of the property. E.g. here is an hCard fragment for marking up a home phone number:

<pre><nowiki>
<span class="tel">
<span class="type">home</span>:
<span class="value">+1.415.555.1212</span>
</span>
</nowiki></pre>

This hCard fragment could be displayed as:

home: +1.415.555.1212

=== Property Exceptions ===

vCard has several properties which either do not make sense on, or are already implied within the context of a web page. This section explains what to (not) do with them.

# '''NAME''', '''PROFILE''', '''SOURCE''', '''PRODID''', '''VERSION''' properties as defined in Sections 2.1.2, 2.1.3, 2.1.4, 3.6.3, 3.6.9 of RFC 2426. Content publishers MUST NOT use these properties in their hCards, and as such, hCard consumers/parsers MUST IGNORE these properties if they are found within an hCard. Instead. hCard to vCard converters SHOULD use the title of the page where the hCard is found (e.g. the <code><title></code> element in (X)HTML documents) to construct the NAME property, MAY output a PROFILE value of "<code>VCARD</code>" per RFC 2426, SHOULD use the URL of the page where the hCard is found to construct the SOURCE property (e.g. perhaps as a parameter to a URL/service that converts hCards to vCards), for an output vCard stream (e.g. a .vcf file). Only services/applications that output actual vCards should write the PRODID property, with the product identifier for said service/application. Similarly only such services/applications should write the VERSION property, with the value "3.0" (without quotes) per RFC2426 Section 3.6.9.

=== Organization Contact Info ===

If the "FN" and "ORG" properties have the exact same value (typically because they are set on the same element, e.g. class="fn org"), then the hCard represents contact information for a company or organization and should be treated as such. In this case the author MUST also NOT set the "N" property, or set it (and any sub-properties) explicitly to the empty string "". Thus parsers should handle the missing "N" property in this case by implying empty values for all the "N" sub-properties.

=== Implied "n" Optimization ===

Although vCard requires that the "N" property be present, the authors of the vCard specification (RFC 2426) themselves do not include "N" properties in their vCards near the end of the spec (p.38). This apparent contradiction can be resolved by simply allowing the "FN" property to imply "N" property values in typical cases provided in the spec. We do so explicitly in hCard.

If "FN" and "ORG" are not the same (see previous section), and the value of the "FN" property is exactly two words (separated by whitespace), and there is no explicit "N" property, then the "N" property is inferred from the "FN" property. For "FN"s with either one word see below, and for three or more, the author MUST explicitly markup the "N", except for the organization contact info case, [http://microformats.org/wiki/hcard#Organization_Contact_Info see above] for that.

# The content of "FN" is broken into two "words" separated by whitespace.
# The ''first'' word of the "FN" is interpreted as the "given-name" for the "N" property.
# The ''second/last'' word of the "FN" is interpreted as the "family-name" for the "N" property.
# Exception: If the first word ends in a "," comma OR if the second word is a single character (optionally followed by a period "."), then the first word (minus the comma at the end if any) is interpreted as the "family-name" and the second word is interpreted as the "given-name".

This allows simplification in the typical case of people stating:
* given-name (space) family-name
* family-name (comma) given-name
* family-name (comma) given-name-first-initial
* family-name (space) given-name-first-initial (optional period)

=== Implied "nickname" Optimization ===

Due to the prevalence of the use of nicknames/handles/usernames on the Web in actual content published on the Web (e.g. authors of [[hReview|reviews]]), hCard also has an implied "nickname" optimization to handle this.

Similar to the implied "n" optimization, if "FN" and "ORG" are not the same, and the value of the "FN" property is exactly one word, and there is no explicit "N" property, then:

# The content of the "FN" is treated as a "nickname" property value.
# Parsers should handle the missing "N" property by implying empty values for all the "N" sub-properties.

Note: the hCard may have additional explicit "nickname" property values in addition to the implied nickname.

=== Implied "organization-name" Optimization ===

The "ORG" property has two subproperties, organization-name and organization-unit. Very often authors only publish the organization-name. Thus if an "ORG" property has no "organization-name" inside it, then its entire contents MUST be treated as the "organization-name".

=== Root Class Name ===

The root class name for an hCard is "vcard".

=== Property List ===

This is the list of properties (and subproperties, in parantheses, like this) in hCard, taken from vCard:

* fn, n (family-name, given-name, additional-name, honorific-prefix, honorific-suffix), nickname, sort-string
* url, email (type, value), tel (type, value)
* adr (post-office-box, extended-address, street-address, locality, region, postal-code, country-name, type, value), label
* geo (latitude, longitude), tz
* photo, logo, sound, bday
* title, role, org (organization-name, organization-unit)
* category, note
* class, key, mailer, uid, rev
==== type subproperty values ====

The 'type' subproperty in particular takes different values depending on which property it is a subproperty of. These 'type' subproperty values are case-INSENSITIVE, meaning "Home" is the same as "home", as well as multivalued, e.g. a tel can be home and preferred:
<pre><nowiki>
<span class="tel"><span class="type">Home</span> (<span class="type">pref</span>erred):
<span class="value">+1.415.555.1212</span>
</span>
</nowiki></pre>

The following lists are ''informative''. See RFC2426 sections 3.2.1 ADR, 3.3.1 TEL, and 3.3.2 EMAIL respectively for normative type values. They are repeated here for convenience. Default type subproperty value(s) is(are) first in each list and indicated in ALL CAPS. types may be multivalued.

* adr type: INTL, POSTAL, PARCEL, WORK, dom, home, pref
* tel type: VOICE, home, msg, work, pref, fax, cell, video, pager, bbs, modem, car, isdn, pcs
* email type: INTERNET, x400, pref, "other IANA registered address types"

=== XMDP Profile ===

See [[hcard-profile]] for the [http://gmpg.org/xmdp XMDP] profile of hCard which contains the above complete list of properties, with references to their RFC 2426 definitions.

=== Parsing Details ===

See [[hcard-parsing|hCard parsing]].

== Examples ==

This section is informative.

=== Sample vCard ===

Here is a sample vCard:

<pre><nowiki>
BEGIN:VCARD
VERSION:3.0
N:Çelik;Tantek
FN:Tantek Çelik
URL:http://tantek.com
ORG:Technorati
END:VCARD
</nowiki></pre>

and an equivalent in hCard with various elements optimized appropriately. See [[hcard-example1-steps| hCard Example 1]] for the derivation.

<pre><nowiki>
<div class="vcard">
<a class="url fn" href="http://tantek.com/">Tantek Çelik</a>
<div class="org">Technorati</div>
</div>
</nowiki></pre>

This hCard might be displayed as:

[http://tantek.com/ Tantek Çelik]<br />
Technorati

Note: The version information is unnecessary in hCard markup directly since the version will be defined by the profile of hCard that is used/referred to in the 'profile' attribute of the <head> element.

=== More Examples ===

See [[hcard-examples]] for more examples, including all examples from vCard RFC 2426 converted into hCard.

== Examples in the wild ==

== Implementations ==
This section is '''informative'''.

The following implementations have been developed which either generate or parse hCards. If you have an hCard implementation, feel free to add it to the top of this list. Once the list grows too big, we'll make a separate wiki page.
*[http://opensource.reevoo.com/2006/03/08/release-uformats-12/ uformats] is a ruby library that can parse [[hCalendar]], [[hCard]], [[hReview]] and [[rel-tag]]
