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.
TOC |
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] (Bradner, S., “Key words for use in RFCs to Indicate Requirement Levels,” March 1997.).
Syntax specifications shown here use the augmented Backus-Naur Form (ABNF) as described in [RFC5234] (Crocker, D. and P. Overell, “Augmented BNF for Syntax Specifications: ABNF,” January 2008.), and are specified as in the base vcard specification [I‑D.ietf‑vcarddav‑vcardrev] (Perreault, S. and P. Resnick, “vCard Format Specification,” December 2010.).

- 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

- 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:

- "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

This presents no security considerations beyond those in section 9 of the base vcard specification [I‑D.ietf‑vcarddav‑vcardrev] (Perreault, S. and P. Resnick, “vCard Format Specification,” December 2010.).

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] (Perreault, S. and P. Resnick, “vCard Format Specification,” December 2010.).
