20+ Best vCard WordPress Themes 2018 - aThemes

vCard, also known as VCF (Virtual Contact File), is a file format standard for electronic business cards. vCards are often attached to e-mail messages, but can be exchanged in other ways, such as on the World Wide Web or instant messaging. They can contain name and address information, telephone numbers, e-mail addresses, URLs, logos, photographs, and audio clips.

vCard is used as data interchange format in Personal digital assistants (PDAs), Personal information managers (PIMs) and Customer relationship management (CRMs). To accomplish these data interchange applications, other "vCard variants" have been used and proposed as "variant standards", each for its specific niche: XML representation, JSON representation or web pages.


Video VCard



Media type

The standard Internet media type (MIME type) for a vCard is:

text/vcard

As of version 4.0 specification, other media types known to have been used previously are now deprecated, including:

text/x-vcard
text/directory;profile=vCard
text/directory

All are oriented to "Directory Information text" (see RFC 2425). Other "vCard variants", oriented to XML and to JSON, are standard proposals (not yet a standard).

Note: The Internet media type text/vcard was used incorrectly in some SyncML documents to refer to vCard 3.0, and the example was followed in various implementations.

Example of vCard files

The following is an example of a vCard file containing information for one person:

vCard 2.1

  BEGIN:VCARD  VERSION:2.1  N:Payne;Tena;;Ms.  FN:Tena Payne  ORG:Earthborn Studios Inc  TITLE:Owner/Designer  PHOTO;JPG:http://earthbornpottery.net/wp-content/uploads/2012/08/gallery.jpg  TEL;WORK;VOICE:(205) 702-7055  TEL;HOME;VOICE:(205) 613-0280  TEL;  ADR;WORK;PREF:;;7575 Parkway Dr;Leeds;AL;35094;United States of America  LABEL;WORK;PREF;ENCODING=QUOTED-PRINTABLE;CHARSET=UTF-8:100 Parkway DR=0D=   =0ALeeds\, AL 35094=0D=0AUnited States of America  ADR;HOME:;;1337 Montevallo Rd;Leeds;AL;35094;United States of America  LABEL;HOME;ENCODING=QUOTED-PRINTABLE;CHARSET=UTF-8:42 Montevallo Rd=0D=0A=   Leeds, AL 35094=0D=0AUnited States of America  EMAIL:earthbornpottery@yahoo.com  REV:20080424T195243Z  END:VCARD  

vCard 3.0

The most used in recent years (ref. 2016) for data interchange.

Example of vCard variants

xCard

It is not a standard, "vCard XML Representation" is a standard proposal of 2011, as RFC 6351.

jCard

jCard is not a standard, it is "The JSON Format for vCard", a standard proposal of 2014, RFC 7095. Other JSON formats (as npm's vcard-json) are in use. The RFC 7095 does not use real JSON objects, but rather uses arrays of sequence-dependent tag-value pairs (like an XML file).

Semantic content

vCard information is common in web pages: the "free text" content is human-readable but not machine-readable. As technologies evolve, the "free text" (HTML) was adapting to be also machine-readable.

  • hCard is a microformat that allows a vCard to be embedded inside an HTML page. It makes use of CSS class names to identify each vCard property. Normal HTML markup and CSS styling can be used alongside the hCard class names without affecting the webpage's ability to be parsed by a hCard parser. h-card is the microformats2 update to hCard.
  • RDFa and Microdata are similar and oriented to Semantic Web: they are replacing hCard, but losting the exact mapping to vCard. Most of vCard properties are mapped using e.g. Schema.org vocabulary (see Person and Organization classes).

Below is an example of first generation hCard.

Properties

vCard defines the following property types.

All vCards begin with BEGIN:VCARD and end with END:VCARD. All vCards must contain the VERSION property, which specifies the vCard version. VERSION must come immediately after BEGIN, except in the vCard 2.1 standard, which allows it to be anywhere in the vCard. Otherwise, properties can be defined in any order.

R = required
S = supported
SP = special, supported
NS = no longer supported as a property but can be used as a parameter inside another property

A handful of separate specifications define additional vCard properties.

vCard extensions

vCard supports private extensions, with an "X-" prefix, a number of which are in common usage.

Some of these include:
