Internet-Draft vCard-Extension July 2011 1. Introduction The base vCard 4.0 specification [I-D.ietf-vcarddav-vcardrev] defines a large number of properties, including date of birth. This specification adds three new properties to vCard 4.0, for place of birth, place of death, and date of death. 1.1. 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]. 2. Identification Property Extensions 2.1. Property: BIRTHPLACE Namespace: Property name: BIRTHPLACE 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 Property parameters: VALUE, LANGUAGE Description: Format definition: BIRTHPLACE-param = "VALUE=" / ("text" / "uri") BIRTHPLACE-value = text / uri ; Value and parameter MUST match. BIRTHPLACE-param =/ altid-param / language-param / any-param Li & Leiba Expires January 6, 2012 [Page 3]

Property: DEATHPLACE Namespace: Property name: DEATHPLACE 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 Property parameters: VALUE, LANGUAGE Description: Format definition: DEATHPLACE-param = "VALUE=" / ("text" / "uri") DEATHPLACE-value = text / uri ; Value and parameter MUST match. DEATHPLACE-param =/ altid-param / language-param / any-param Examples: DEATHPLACE:Aboard the Titanic\, near Newfoundland DEATHPLACE;VALUE=uri:http://example.com/ships/titanic.vcf DEATHPLACE;VALUE=uri:41.731944,-49.945833 2.3. Property: DEATHDATE Namespace: Property name: DEATHDATE 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. Li & Leiba Expires January 6, 2012 [Page 4]
Internet-Draft vCard-Extension July 2011 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 be present when the value is text. Description: Format definition: DEATHDATE-param = DEATHDATE-param-date / DEATHDATE-param-text DEATHDATE-value = date-and-or-time / text ; Value and parameter MUST match. DEATHDATE-param-date = "VALUE=date-and-or-time" DEATHDATE-param-text = "VALUE=text" / language-param DEATHDATE-param =/ altid-param / calscale-param / any-param ; calscale-param can only be present when DEATHDATE-value is ; date-and-or-time and actually contains a date or date-time. Examples: DEATHDATE:19960415 DEATHDATE:--0415 DEATHDATE;19531015T231000Z DEATHDATE;VALUE=text:circa 1800 3. Security Considerations This presents no security considerations beyond those in section 9 of the base vcard specification [I-D.ietf-vcarddav-vcardrev]. 4. IANA Considerations The IANA is requested to add the following entries to the vCard Properties registry, defined in [I-D.ietf-vcarddav-vcardrev] section 10.3.1. +-----------+--------------+---------+------------------------+ | Namespace | Property | Status | Reference | +-----------+--------------+---------+------------------------+ | | BIRTHPLACE | Current | RFCXXXX, section 2.1 | | | DEATHPLACE | Current | RFCXXXX, section 2.2 | | | DEATHDATE | Current | RFCXXXX, section 2.3 | +-----------+--------------+---------+------------------------+ Li & Leiba Expires January 6, 2012 [Page 5]
