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 Li & Leiba Expires July 2, 2011 [Page 3] 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]. Li & Leiba Expires July 2, 2011 [Page 4] Internet-Draft vCard-Extension December 2010 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 5.2. Registration of 'BIRTH' property Li & Leiba Expires July 2, 2011 [Page 5] Internet-Draft vCard-Extension December 2010 Namespace: Property name: BIRTH Purpose: 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: BIRTH-param = "VALUE=" / ("text" / "uri") BIRTH-value = text / uri ; Value and parameter MUST match. BIRTH-param =/ altid-param / language-param / any-param Example(s): BIRTH:Babies'R'Us Hospital BIRTH;VALUE=uri:http://example.com/hospitals/babiesrus.vcf BIRTH;VALUE=uri:geo:46.769307,-71.283079 5.3. Registration of 'DEATH' property Namespace: Property name: DEATH Purpose: 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: DEATH-param = "VALUE=" / ("text" / "uri") Li & Leiba Expires July 2, 2011 [Page 6] Internet-Draft vCard-Extension December 2010 DEATH-value = text / uri ; Value and parameter MUST match. DEATH-param =/ altid-param / language-param / any-param Example(s): DEATH:Aboard the Titanic\, near Newfoundland DEATH;VALUE=uri:http://example.com/ships/titanic.vcf DEATH;VALUE=uri:41.731944,-49.945833 6.
