Instructive Examples

Authors of Pages and Posts

Per the HTML4.01 specification, authors should be using the <address> element to indicate the "contact information for a document or a major part of a document." E.g.

<address>
 <a href="http://tantek.com/">Tantek Çelik</a>
</address>

By adding hCard to such existing semantic XHTML, you can explicitly indicate the name of the person, their URL, etc.:

<address class="vcard">
 <a class="fn url" href="http://tantek.com/">Tantek Çelik</a>
</address>

This could be displayed as:

Tantek Çelik

This works not only for whole pages, but also for "major part[s]" of pages, e.g. blog posts.

See the microformats.org blog (view the source) for a live example. The author of every blog post on the microformats.org blog is marked up as an <address class="vcard"> element like the example shown above.

References to People and Organizations

A common pattern in blog posts is to link mentions of people's names to their blogs, and/or organizations to their home pages. E.g.:

<cite><a href="http://meyerweb.com/">Eric Meyer</a></cite> wrote a post 
(<cite><a href="http://meyerweb.com/eric/thoughts/2005/12/16/tax-relief/">Tax Relief</a></cite>) 
about an unintentionally humorous letter he received from the
<a href="http://irs.gov/">Internal Revenue Service</a>.

By adding hCard to such markup, you can explicitly indicate both the person and the organization by name and URL:

<cite class="vcard"><a class="fn url" href="http://meyerweb.com/">Eric Meyer</a></cite> wrote a post 
(<cite><a href="http://meyerweb.com/eric/thoughts/2005/12/16/tax-relief/">Tax Relief</a></cite>) 
about an unintentionally humorous letter he received from the
<span class="vcard"><a class="fn org url" href="http://irs.gov/">Internal Revenue Service</a>.

This could be displayed as:

Eric Meyer wrote a post (Tax Relief) about an unintentionally humorous letter he received from the Internal Revenue Service.

hCard and XFN

References to People in Blog Posts

In the above example, one person (the blogger) is referring to another person (Eric Meyer). In addition to using hCard to explicitly mark up the reference as a person, the blogger can use XFN (the XHTML Friends Network) to indicate their relationship to Eric Meyer, e.g.:

<cite class="vcard"><a class="fn url" rel="friend colleague met" href="http://meyerweb.com/">Eric Meyer</a></cite> wrote a post 
(<cite><a href="http://meyerweb.com/eric/thoughts/2005/12/16/tax-relief/">Tax Relief</a></cite>) 
about an unintentionally humorous letter he received from the
<span class="vcard"><a class="fn org url" href="http://irs.gov/">Internal Revenue Service</a></span>.

It would be displayed the same as the previous example.

References to People in Blogrolls

Many bloggers are using XFN (often using an easy user interface like that built into WordPress) to explicitly indicate their relationships to the people in their blogrolls:

<ul>
 <li><a href="http://meyerweb.com" rel="friend colleague met">Eric Meyer</a></li>
 <li><a href="http://photomatt.net" rel="friend colleague met">Matt Mullenweg</a></li>
</ul>

By adding hCard markup to an XFN Friendly blogroll, you can explicitly indicate the name and URL of the person in addition to their relationship:

<ul>
 <li class="vcard"><a class="fn url" href="http://meyerweb.com" rel="friend colleague met">Eric Meyer</a></li>
 <li class="vcard"><a class="fn url" href="http://photomatt.net" rel="friend colleague met">Matt Mullenweg</a></li>
</ul>

This could be displayed as:

For more information on XFN, see the XFN home page, joining XFN, and background on XFN.

New Types of Contact Info

Since vCard was designed, there have been numerous other services that provide individuals with addresses or other means of contact, e.g. instant messaging, voip, etc.

Does this mean that vCard (and hence hCard) must be extended to represent these?

Thanks to the flexibility of the URL property, the answer is no, no extensions are necessary. Instead, we use the proper URL for the service which identifies the service (protocol, machine, and/or path), and place the individual's address inside that.

AOL Instant Messenger (AIM)

AOL Instant Messenger (AIM) ids can be represented using the aim: protocol. Many who publish their AIM ids do so with clickable URLs e.g.:

<a href="aim:goim?screenname=ShoppingBuddy">IM with the AIM ShoppingBuddy</a>

Thus for hCard, we will adopt this existing content publisher behavior, and simply capture it as another URL for the hCard:

<a class="url" href="aim:goim?screenname=ShoppingBuddy">IM with the AIM ShoppingBuddy</a>

Yahoo Messenger

Similarly, Yahoo Instant Messenger (YIM) ids can be represented using the ymsgr: protocol. And similarly many publish their YIM ids as clickable URLs e.g.:

<a href="ymsgr:sendIM?SomeYahooFriend">IM with SomeYahooFriend</a>

Again, for hCard, we will adopt this existing content publisher behavior, and simply capture it as another URL for the hCard:

<a class="url" href="ymsgr:sendIM?SomeYahooFriend">IM with SomeYahooFriend</a>

MSN Messenger

Unfortunately, AFAIK, there is no hacked up defacto protocol for opening an MSN IM session with an MSN userid (which themselves are just email addresses). Thus we must simply resort to marking them up as email addresses, and expect that consumers may use some heuristic, such as "hotmail.com email addresses are also MSN IM ids". -Tantek

MSN Messenger (MSNIM) ids can be represented using the msnim: protocol. And similarly many publish their MSNIM ids as clickable URLs e.g.:

<a href="msnim:chat?contact=joebob@hotmail.com">IM with joebob@hotmail.com</a>

For hCard, we will adopt this existing content publisher behavior, and simply capture it as another URL for the hCard:

<a class="url" href="msnim:chat?contact=joebob@hotmail.com">IM with joebob@hotmail.com</a>

Updated 14 May 2006 - Ruben

Ruben, I tried this, and "msnim:" is an unrecognized protocol on MacOSX.4 (this is with the latest MSN Messenger for Mac installed and running and logged int). Could you provide links to documentation about "msnim:" and links to actual pages that publish their MSNIM ids this way? I don't know of any - Tantek

Site profiles

Bloggers often indicate their identity on content hosting services using the URL to their home page, feed or profile on those services. By labeling them as URL properties, these additional facets of identity can be publish in an hCard as well.

RFC 2426 examples in hCard

These are 1:1 hCard examples for each example in RFC 2426.

Mark Pilgrim has made these hCard examples available as separate files:

This vCard fragment has one property whose value is another vCard, and could be represented as an hCard fragment with an embedded hCard, literally (with the unnecessary type=internet default omitted, and the implied n optimization):

<div class="agent vcard">

ljYXRpb25zIENvcnBvcmF0aW9uMRwwGgYDVQQLExNJbmZvcm1hdGlvbiBTeXN0
<...the remainder of "B" encoded binary data...>

this vCard fragment as an hCard fragment

<img class="logo" src="data:image/jpeg;base64,MIICajCCAdOgAwIBAgICBEUwDQYJKoZIhvcN
AQEEBQAwdzELMAkGA1UEBhMCVVMxLDAqBgNVBAoTI05ldHNjYXBlIENvbW11bm
ljYXRpb25zIENvcnBvcmF0aW9uMRwwGgYDVQQLExNJbmZvcm1hdGlvbiBTeXN0
...remainder of B encoded binary data..." alt="" />

no display equivalent given, since data: URL from original example is incomplete.

3.5.4 AGENT Type Definition

AGENT;VALUE=uri:
 CID:JQPUBLIC.part3.960129T083020.xyzMail@host3.com

this vCard fragment as an hCard fragment

<a class="agent" href="CID:JQPUBLIC.part3.960129T083020.xyzMail@host3.com">JQPUBLIC</a>

 <a class="email fn n" href="mailto:sthomas@host.com">Susan Thomas</a>,
 <span class="tel">+1-919-555-1234</span>
</span>

this hCard fragment could be displayed as:

Susan Thomas, +1-919-555-1234

Note: the vCard in the AGENT property vCard fragment is actually invalid since it lacks an "N" property. However, the hCard version *is* valid, since I added the "n" class name to the example.

3.5.5 ORG Type Definition

ORG:ABC\, Inc.;North American Division;Marketing

this vCard fragment as an hCard fragment:

<span class="org">
 <span class="organization-name">ABC, Inc.</span>, 
 <span class="organization-unit">North American Division</span>,
 <span class="organization-unit">Marketing</span>,
</span>

this hCard fragment could be displayed as:

ABC, Inc., North American Division, Marketing

3.6.1 CATEGORIES Type Definition

CATEGORIES:TRAVEL AGENT

this vCard fragment as an hCard fragment:

<span class="category">TRAVEL AGENT</span>

this hCard fragment could be displayed as:

TRAVEL AGENT

Example 2

this vCard fragment as an hCard fragment:

<span class="category">INTERNET</span>, 
<span class="category">IETF</span>, 
<span class="category">INDUSTRY</span>, 
<span class="category">INFORMATION TECHNOLOGY</span>

this hCard fragment would be displayed as:

INTERNET, IETF, INDUSTRY, INFORMATION TECHNOLOGY

3.6.2 NOTE Type Definition

NOTE:This fax number is operational 0800 to 1715
 EST\, Mon-Fri.

this vCard fragment as an hCard fragment:

<p class="note">This fax number is operational 0800 to 1715 EST, Mon-Fri.</p>

this hCard fragment could be displayed as:

This fax number is operational 0800 to 1715 EST, Mon-Fri.

3.6.3 PRODID Type Definition

PRODID:-//ONLINE DIRECTORY//NONSGML Version 1//EN

Note, this vCard property actually doesn't make sense as a hCard property, since it really should be filled in by whatever code transforms the hCard into a vCard, e.g. Brian Suda's X2V.

3.6.4 REV Type Definition

Example 1

REV:1995-10-31T22:27:10Z

this vCard fragment as an hCard fragment:

<abbr class="rev" title="1995-10-31T22:27:10Z">Updated: 10/31 10:27p</abbr>

this hCard fragment could be displayed as:

Updated: 10/31 10:27p

Example 2

REV:1997-11-15

this vCard fragment as an hCard fragment:

<abbr class="rev" title="1997-11-15">Updated: November 15</abbr>

this hCard fragment could be displayed as:

Updated: November 15

3.6.5 SORT-STRING Type Definition

Example 1

FN:Rene van der Harten
N:van der Harten;Rene;J.;Sir;R.D.O.N.
SORT-STRING:Harten

this vCard fragment as an hCard fragment:

<span class="n"
 <span class="honorific-prefix">Sir</span>
 <span class="fn">
  <span class="given-name">Rene</span>
  <span class="family-name">
   van der <span class="sort-string">Harten</span>
  </span>
 </span>
 (<span class="additional-name">J.</span>),
 <span class="honorific-suffix">R.D.O.N.</span>
</span>

Note: The string "Harten" was NOT repeated in the hCard, even though it WAS repeated in the vCard (3 times! In N, FN, and SORT-STRING). The "SORT-STRING" property provides another good demonstration of how hCard enables better adherence to the DRY principle than vCard.

this hCard fragment could be displayed as:

Sir Rene van der Harten (J.), R.D.O.N.

Example 2

FN:Robert Pau Shou Chang
N:Pau;Shou Chang;Robert
SORT-STRING:Pau

this vCard fragment as an hCard fragment:

<span class="fn n">
 <span class="additional-name">Robert</span>
 <span class="family-name sort-string">Pau</span>
 <span class="given-name">Shou Chang</span>
</span>

Note: Not only was the string "Pau" was NOT repeated in the hCard (better DRY principle adherence again), even though it WAS repeated in the vCard, but in this case since the "family-name" and "sort-string" are the same, we were able to use element conservation and use only one element for both properties.

this hCard fragment could be displayed as:

Robert Pau Shou Chang

Example 3

FN:Osamu Koura
N:Koura;Osamu
SORT-STRING:Koura

this vCard fragment as an hCard fragment:

<span class="fn">
 Osamu <span class="sort-string">Koura</span>
</span>

Note: This example, in addition to illustrating better support for the DRY principle, also makes use of the Implied "N" Optimization.

this hCard fragment could be displayed as:

Osamu Koura

Example 4

FN:Oscar del Pozo
N:del Pozo Triscon;Oscar
SORT-STRING:Pozo

this vCard fragment as an hCard fragment:

<span class="n">
 <span class="fn">
  <span class="given-name">Oscar</span>
  del <span class="sort-string">Pozo</span>
 </span>
 <span class="family-name" style="display:none">
  del Pozo Triscon
 </span>
</span>

Note: This example unfortunately could not completely adhere to the DRY principle due to the "FN" using a *substring* of the family-name, and in addition thus had to hide the extra "family-name" string value using CSS display:none, which in general should be avoided. Suggestion welcome for improvements on this hCard fragement.

this hCard fragment could be displayed as:

Oscar del Pozo

Example 5

FN:Christine d'Aboville
N:d'Aboville;Christine
SORT-STRING:Aboville

this vCard fragment as an hCard fragment:

<span class="fn">
 Christine d'<span class="sort-string">Aboville</span>
</span>

Note: This example re-demonstrates the same hCard advantages/efficiencies demonstrated in example 3 above.

this hCard fragment could be displayed as:

Christine d'Aboville

3.6.6 SOUND Type Definition

Example 1

SOUND;TYPE=BASIC;VALUE=uri:CID:JOHNQPUBLIC.part8.
 19960229T080000.xyzMail@host1.com

this vCard fragment as an hCard fragment

<object class="sound" type="audio/basic"
 data="CID:JOHNQPUBLIC.part8.19960229T080000.xyzMail@host1.com">
pronounciation of "JOHN Q PUBLIC"
</object>

this hCard fragment would probably be displayed as

pronounciation of "JOHN Q PUBLIC"

unless your browser supports the MIME type "audio/basic" (defined in RFC2046 section 4.3) and has some way of retrieving "CID:" urls.

Example 2

SOUND;TYPE=BASIC;ENCODING=b:MIICajCCAdOgAwIBAgICBEUwDQYJKoZIhvcN
 AQEEBQAwdzELMAkGA1UEBhMCVVMxLDAqBgNVBAoTI05ldHNjYXBlIENvbW11bm
 ljYXRpb25zIENvcnBvcmF0aW9uMRwwGgYDVQQLExNJbmZvcm1hdGlvbiBTeXN0
 <...the remainder of "B" encoded binary data...>

this vCard fragment as an hCard fragment

<object class="sound" 
data="data:audio/basic;base64,MIICajCCAdOgAwIBAgICBEUwDQYJKoZIhvcN
 AQEEBQAwdzELMAkGA1UEBhMCVVMxLDAqBgNVBAoTI05ldHNjYXBlIENvbW11bm
 ljYXRpb25zIENvcnBvcmF0aW9uMRwwGgYDVQQLExNJbmZvcm1hdGlvbiBTeXN0
 ...the remainder of "B" encoded binary data...">
pronounciation
</object>

no display equivalent given, since data: URL from original example is incomplete.

3.6.7 UID Type Definition

UID:19950401-080045-40000F192713-0052

this vCard fragment as an hCard fragment

Unique id: 
 <span class="uid">19950401-080045-40000F192713-0052</span>

Note: Because of the lack of a TYPE value in the RFC2426 example, I substituted application/octet-stream. Clearly for it to be of some use, the type specified must be some sort of key or certificate mime type.

Note that both of these vCards are invalid since they lack the REQUIRED "N" property which is quite ironic, since these are the vCards of the authors themselves.

Test Cases

These are hCard examples which have been found to be particularly useful in finding bugs in hCard parsers (e.g. X2V).

Problem with BDAY Information

this example:

    <!-- birthday -->
    <div class="bday">
    <dt>Birthday</dt>
    <dd>
        <abbr class="value" title="1985-10-27T00:00:00Z">October 27, 1985</abbr>
    </dd>
    </div>

ought to produce "BDAY:1985-10-27T00:00:00Z" but it produces "BDAY:Birthday October 27\, 1985". interesting is that the apple addressbook is still willing to accept it in this way.

case-INSENSITIVITY of type values

"home" vs. "Home"

this example works with X2V:

    <div class="tel">
    <dt>Phone (<span class="type">home</span>)</dt>
    <dd><span class="value">+438123418</span></dd>
    </div>

this does not, but should. but instead it becomes just TEL without a type in the vcard

    <div class="tel">
    <dt>Phone (<span class="type">Home</span>)</dt>
    <dd><span class="value">+438123418</span></dd>
    </div>

GEO parsing

The following hCard:

<div class="vcard">
  <span class="n">
     <a class="url" href="http://t37.net">
       <span class="given-name">Fréderic</span> 
       <span class="family-name">de Villamil</span> 
     </a>
  </span>
  <span class="nickname">neuro</span>
  <a class="email" href="mailto:neuroNOSPAM@t37.net">
     <span class="type">pref<span>erred</span> email</span>
  </a>
  <span class="org">Omatis</span>
  <span class="adr">
     <abbr class="type" title="dom">France</abbr>
     <span class="type">home</span> address
     <abbr class="type" title="postal">mail</abbr> and
     <abbr class="type" title="parcel">shipments</abbr>:
     <span class="street-address">12 rue Danton</span>
     <span class="locality">Le Kremlin-Bicetre</span>
     <span class="postal-code">94270</span>
     <span class="country-name">France</span>
  </span>
  <span class="geo">
     <abbr class="latitude" title="48.816667">N 48° 81.6667</abbr>
     <abbr class="longitude" title="2.366667">E 2° 36.6667</abbr>
  </span>
</div>

Should be translated into the following vCard:

BEGIN:VCARD
VERSION:3.0
URL:http://t37.net
ORG:Omatis;;
NICKNAME:neuro
N:de Villamil;Frederic;;Mr.;
EMAIL;TYPE=INTERNET,PREF:neuroNOSPAM@t37.net
ADR;TYPE=HOME:;;12 rue danton;le Kremlin-Bicetre;;94270;France
GEO:48.816667;2.366667
END:VCARD

X2V currently (2005-12-18) fails to parse/export the GEO property at all.

 MSN Messenger (MSNIM) ids can be represented using the <code>msnim:</code> protocol. And similarly many publish their MSNIM ids as clickable URLs e.g.:

+Ruben, I tried this, and "msnim:" is an unrecognized protocol on MacOSX.4 (this is with the latest MSN Messenger for Mac installed and running and logged int).  Could you provide links to documentation about "msnim:" and links to actual pages that publish their MSNIM ids this way?  I don't know of any - [http://tantek.com/ Tantek]
