Internet-Draft vCard-Extension December 2010
1. Introduction
This specification adds three new properties to vCard 4.0: DDAY to
specify the date of death, BIRTH to specify the place of birth, DEATH
to specify the place of death, of the object the vCard represents.
2. Terminology Used in This Document
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 [RFC2119].
Syntax specifications shown here use the augmented Backus-Naur Form
(ABNF) as described in [RFC5234], and are specified as in the base
vcard specification [I-D.ietf-vcarddav-vcardrev].
3. Identification Property Extensions
3.1. Property: DDAY
Purpose: To specify the date of death of the object the vCard
represents.
Value type: The default is a single date-and-or-time value. It can
also be reset to a single text value.
Cardinality: *1
ABNF:
DDAY-param = DDAY-param-date / DDAY-param-text
DDAY-value = date-and-or-time / text
; Value and parameter MUST match.
DDAY-param-date = "VALUE=date-and-or-time"
DDAY-param-text = "VALUE=text" / language-param
DDAY-param =/ altid-param / calscale-param / any-param
; calscale-param can only be present when DDAY-value is
; date-and-or-time and actually contains a date or date-time.
Examples:
DDAY:19960415
DDAY:--0415
DDAY;19531015T231000Z
DDAY;VALUE=text:circa 1800

Internet-Draft vCard-Extension December 2010
3.2. Property: BIRTH
Purpose: To specify the place of birth of the object the vCard
represents.
Value type: A single text value (default) or a single URI value.
Cardinality: *1
ABNF:
BIRTH-param = "VALUE=" / ("text" / "uri")
BIRTH-value = text / uri
; Value and parameter MUST match.
BIRTH-param =/ altid-param / language-param / any-param
Examples:
BIRTH:Babies'R'Us Hospital
BIRTH;VALUE=uri:http://example.com/hospitals/babiesrus.vcf
BIRTH;VALUE=uri:geo:46.769307,-71.283079
3.3. Property: DEATH
Purpose: To specify the place of death of the object the vCard
represents.
Value type: A single text value (default) or a single URI value.
Cardinality: *1
ABNF:
DEATH-param = "VALUE=" / ("text" / "uri")
DEATH-value = text / uri
; Value and parameter MUST match.
DEATH-param =/ altid-param / language-param / any-param
Examples:
DEATH:Aboard the Titanic\, near Newfoundland
DEATH;VALUE=uri:http://example.com/ships/titanic.vcf
DEATH;VALUE=uri:41.731944,-49.945833
4. Security Considerations
This presents no security considerations beyond those in section 9 of
the base vcard specification [I-D.ietf-vcarddav-vcardrev].

5. IANA Considerations
Registrations are requested for the three properties (DDAY, BIRTH,
DEATH), according to the instructions in section 10.2.3 of the base
vcard specification [I-D.ietf-vcarddav-vcardrev].
5.1. Registration of 'DDAY' property
Namespace:
Property name: DDAY
Purpose: The date of death of the object the vCard represents.
Value type: The default is a single date-and-or-time value. It can
also be reset to a single text value.
Cardinality: *1
Property parameters: VALUE, CALSCALE, LANGUAGE
CALSCALE can only be present when the value is a
date-and-or-time value and actually contains a date or date-time.
LANGUAGE can only b present when the value is text.
Description:
Format definition:
DDAY-param = DDAY-param-date / DDAY-param-text
DDAY-value = date-and-or-time / text
; Value and parameter MUST match.
DDAY-param-date = "VALUE=date-and-or-time"
DDAY-param-text = "VALUE=text" / language-param
DDAY-param =/ altid-param / calscale-param / any-param
; calscale-param can only be present when DDAY-value is
; date-and-or-time and actually contains a date or date-time.
Example(s):
DDAY:19960415
DDAY:--0415
DDAY;19531015T231000Z
DDAY;VALUE=text:circa 1800
