Abstract Abstract
This specification defines a data model and JSON representation of This specification defines a data model and JavaScript Object

extendable and simple to process. In contrast to the JSON-based and to be unambiguous, extendable, and simple to process. In
jCard format, it is not a direct mapping from the vCard data model contrast to the JSON-based jCard format, it is not a direct mapping

Two additional specifications define new vCard elements and how to
convert between JSContact and vCard.

1.1. Motivation and Relation to vCard, jCard and xCard 1.1. Motivation and Relation to vCard, jCard, and xCard

Two additional documents define the relation of JSContact and vCard:
[RFC9554] defines new vCard properties and parameters, and [RFC9555]
defines how to convert JSContact data from and to vCard.
The xCard [RFC6351] and jCard [RFC7095] specifications define The xCard [RFC6351] and jCard [RFC7095] specifications define

1.3.1. Objects and Properties 1.3.1. Objects and Properties
JSContact defines data types for contact information such as JSContact defines data types for contact information such as
addresses or names. This information typically consists of multiple addresses or names. This information typically consists of multiple
related elements, for example a personal name and surname together related elements; for example, a personal name and surname together
form a name. These related elements are organized in JSContact form a name. These related elements are organized in JSContact
objects. A JSContact object is a JSON object which: objects. A JSContact object is a JSON object that has the following:
1. Has a unique type name registered in the IANA JSContact Types 1. A unique type name registered in the IANA "JSContact Types"
Registry (Section 3.6). registry (Section 3.6).
2. Has one or more object members for which the name and allowed 2. One or more object members for which the name and allowed value
value types are specified. Such members are called "properties". types are specified. Such members are called "properties".
3. Has one property named @type with a string value that matches the 3. One property named @type with a string value that matches the
type name of this JSContact object. In general, this property type name of the JSContact object. In general, this property
does not need to be set explicitly as outlined in Section 1.3.4. does not need to be set explicitly as outlined in Section 1.3.4.
The following sections specify how to define JSContact object types. The following sections specify how to define JSContact object types.
Section 1.7 and Section 1.8 then define the exact requirements for Sections 1.7 and 1.8 then define the exact requirements for property

The next paragraph illustrates how a JSContact object is defined: The next paragraph illustrates how a JSContact object is defined.
The names "Foo" and "baz" are only for demonstration and have no
meaning outside the example.

be valid. Finally, a free-text description describes the semantics
and further restrictions. The above paragraph illustrates the following:
* It defines a JSContact object type named "Foo" that has two
properties, named "@type" and "baz".
* The @type property adheres to the rules outlined in Section 1.3.4.
Because of this, it is neither defined to be mandatory nor
optional, as this depends on how the Foo object type is used.
* The baz property value MUST be valid according to the definition
of the Number type.
* The property has one attribute, "mandatory", which specifies that
the property MUST be present for a value of the Foo object type to
be valid.
* The free-text description of the baz property describes the
semantics and further restrictions for its values.

A version value is produced by the following ABNF:
