1.  Introduction

   The base vCard 4.0 specification [RFC6350] defines a large number of
   properties, including date of birth.  This specification adds three
   new properties to vCard 4.0: 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 [RFC6350].

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 type and VALUE parameter MUST match.

      BIRTHPLACE-param =/  altid-param / language-param / any-param

   Examples:

      BIRTHPLACE:Babies'R'Us Hospital
      BIRTHPLACE;VALUE=uri:http://example.com/hospitals/babiesrus.vcf
      BIRTHPLACE;VALUE=uri:geo:46.769307\,-71.283079 
EID 4557 (Verified) is as follows:

Section: 2.1

Original Text:

BIRTHPLACE;VALUE=uri:geo:46.769307,-71.283079

Corrected Text:

BIRTHPLACE;VALUE=uri:geo:46.769307\,-71.283079
Notes:
Section 3.4 in RFC 6350 states that all property values must have COMMA characters escaped with a BACKSLASH character. The BIRTHPLACE property value in the example contains a comma. Therefore it must be escaped with a backslash.
2.2. 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 type and VALUE 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:geo:41.731944\,-49.945833
EID 4559 (Verified) is as follows:

Section: 2.2

Original Text:

DEATHPLACE;VALUE=uri:geo:41.731944,-49.945833

Corrected Text:

DEATHPLACE;VALUE=uri:geo:41.731944\,-49.945833
Notes:
Section 3.4 in RFC 6350 states that all property values must have COMMA characters escaped with a BACKSLASH character. The DEATHPLACE property value in the example contains a comma. Therefore it must be escaped with a backslash.
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. 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: The presence of a DEATHDATE property indicates that the subject of the vCard is known to be dead. The absence of this property makes no statement one way or the other. Format definition: DEATHDATE-param = DEATHDATE-param-date / DEATHDATE-param-text DEATHDATE-value = date-and-or-time / text ; Value type and VALUE parameter MUST match. DEATHDATE-param-date = "VALUE=date-and-or-time" / calscale-param ; calscale-param can only be present when DEATHDATE-value is ; date-and-or-time and actually contains a date or date-time. DEATHDATE-param-date = "VALUE=text" / language-param DEATHDATE-param =/ altid-param / any-param Examples: DEATHDATE:19960415 DEATHDATE:--0415 DEATHDATE:19531015T231000Z
EID 4556 (Verified) is as follows:

Section: 2.3

Original Text:

DEATHDATE;19531015T231000Z

Corrected Text:

DEATHDATE:19531015T231000Z
Notes:
A typo when declaring the third DEATHDATE property example: It is a colon, not a semi-colon.
DEATHDATE;VALUE=text:circa 1800 3. Security Considerations The properties defined in this document present no security considerations beyond those in Section 9 of the base vCard specification [RFC6350]. 4. IANA Considerations IANA has added the following entries to the vCard Properties registry, defined in Section 10.3.1 of [RFC6350]. +-----------+--------------+------------------------+ | Namespace | Property | Reference | +-----------+--------------+------------------------+ | | BIRTHPLACE | [RFC6474], Section 2.1 | | | DEATHPLACE | [RFC6474], Section 2.2 | | | DEATHDATE | [RFC6474], Section 2.3 | +-----------+--------------+------------------------+ 5.
