      <t>This specification defines a data model and JSON JavaScript Object Notation (JSON) representation of contact card information that can be used for data storage and exchange in address book or directory applications.  It aims to be an alternative to the vCard data format and to be unambiguous, extendable extendable, and simple to process.  In contrast to the JSON-based jCard format, it is not a direct mapping from the vCard data model and expands semantics where appropriate.</t>

      <name>Introduction</name>
      <t>This document defines a data model for contact card data normally used in address book or directory applications and services.  It aims to be an alternative to the vCard data format <xref target="RFC6350" format="default"/>.</t>
      <t>The key design considerations for this data model are as follows:</t>
      <ul spacing="normal">
        <li>The data model and set of attributes should mostly be mostly compatible with the one model defined for the vCard data format <xref target="RFC6350" format="default"/> and extensions (<xref <xref target="RFC6473" format="default"/>, format="default"/> <xref target="RFC6474" format="default"/>, format="default"/> <xref target="RFC6715" format="default"/>, format="default"/> <xref target="RFC6869" format="default"/>, format="default"/> <xref target="RFC8605" format="default"/>). format="default"/>.  The specification should add new attributes or value types where appropriate. Not all existing vCard definitions need an equivalent in JSContact, especially if the vCard definition is considered to be obsolete or otherwise inappropriate.  Conversion between the data formats need not fully preserve semantic meaning.</li>

<!--[rfced] Please clarify the meaning of "reducing complexity of
their representation". Is the intended meaning that the
attributes must be described as simple key-value pairs to
reduce complexity (option A) or to reduce complexity of the
representation of the card data (option B)?

Original:
   The attributes of the card data represented must be described as
   simple key-value pairs, reducing complexity of their
   representation.

Perhaps:
A) The attributes of the card data being represented must be
   described as simple key-value pairs to reduce complexity.

or

B) The attributes of the card data must be described as simple
   key-value pairs to reduce the complexity of the representation
   of the card data.
-->

        <li>The attributes of the card data represented must be described as simple key-value pairs, reducing complexity of their representation.</li>
        <li>The data model should avoid all ambiguities and make it difficult to make mistakes during implementation.</li>
        <li>Extensions, such as new properties and components, <bcp14>MUST NOT</bcp14> lead to requiring an a required update to of this document.</li>
      </ul>
      <t>The representation of this data model is defined in the I-JSON Internet JSON (I-JSON) format <xref target="RFC7493" format="default"/>, which is a strict subset of the JavaScript Object Notation (JSON) Data Interchange Format JSON data interchange format <xref target="RFC8259" format="default"/>.  Using JSON is mostly a pragmatic choice: its widespread use makes JSContact easier to adopt, and the availability of production-ready JSON implementations eliminates a whole category of parser-related interoperability issues.</t>
      <section anchor="relation-to-vcard" numbered="true" toc="default">
        <name>Motivation and Relation to vCard, jCard jCard, and xCard</name>
        <t>The vCard data format <xref target="RFC6350"/> is an interchange format for contacts data between address book service providers and vendors.  However, this format has gone through multiple specifications specification iterations with only a subset of its deprecated <xref target="RFC2426">version 3</xref> being widely in use.  Consequently, products and services internally use a richer an internal contact data model that is richer than what they expose when serializing that information to vCard.  In addition, service providers often use a proprietary JSON representation of contact data in their APIs.</t>
        <t>JSContact provides a standard JSON-based data model and representation of contact data as an alternative to proprietary formats.</t>
        <t>While
        <t>At the time of writing this document, several features missing features in vCard were brought to the attention of the authors, authors such as social media contacts, gender pronouns pronouns, and others.  This highlights how vCard is not perceived as an evolving format and consequently and, consequently, hasn't been updated since close to for about ten years.  JSContact addresses these unmet demands and defines new vCard properties and parameters to allow interchanging them in both formats.</t>
        <t>The xCard <xref target="RFC6351" format="default"/> and jCard <xref target="RFC7095" format="default"/> specifications define alternative representations for vCard data, data in XML and JSON format formats, respectively.  Both explicitly aim to not change the underlying data model.  Accordingly, they are regarded as equal to vCard in the context of this document.</t>

          <t>JSContact defines data types for contact information such as addresses or names.  This information typically consists of multiple related elements, elements; for example example, a personal name and surname together form a name.  These related elements are organized in JSContact objects.  A JSContact object is a JSON object which:</t> that has the following:</t>
          <ol>
            <li>Has a
            <li>A unique type name registered in the IANA  <xref target="iana-type-registry">IANA JSContact Types Registry</xref>.</li>

            <li>Has one
            <li>One property named <tt>@type</tt> with a string value that matches the type name of this the JSContact object.  In general, this property does not need to be set explicitly as outlined in <xref target="prop-type"/>.</li>
          </ol>

        <name>Common Data Types</name>
        <t>In addition to the standard JSON data types, a couple of additional data types are common to the definitions of JSContact objects and properties.</t>

          <t>Where <tt>Id</tt> is given as a data type, it means a <tt>String</tt> of at least 1 and a maximum of 255 octets in size, and it <bcp14>MUST</bcp14> only contain characters from the <tt>URL and Filename Safe</tt> base64url alphabet, as defined in Section 5 of <xref target="RFC4648" format="default"/>, sectionFormat="of" section="5"/>, excluding the pad character (<tt>=</tt>).  This means the allowed characters are the ASCII alphanumeric characters (<tt>A-Za-z0-9</tt>), hyphen (<tt>-</tt>), and underscore (<tt>_</tt>).</t>
          <t>In many places in JSContact JSContact, a JSON map is used where the map keys are of type Id and the map values are all the same type of object.  This construction represents an unordered set of objects, with the added advantage that each entry has a name (the corresponding map key).  This allows for more concise patching of objects, objects and, when applicable, for the objects in question to be referenced from other objects within the JSContact object.  The map keys <bcp14>MUST</bcp14> be preserved across multiple versions of the JSContact object.</t>
          <t>Unless otherwise specified for a particular property, there are no uniqueness constraints on an Id value (other than, of course, the requirement that you cannot have two values with the same key within a single JSON map).  For example, two <xref target="card">Card</xref> objects might use the same Ids in their respective <tt>photos</tt> properties.  Or within the same Card Card, the same Id could appear in the <tt>emails</tt> and <tt>phones</tt> properties.  These situations do not imply any semantic connections among the objects.</t>

            Vendor-specific property names <bcp14>MUST</bcp14> start with a vendor-specific prefix followed by a name, as produced by the <tt>v-extension</tt> ABNF below.  The prefix and name together form the property name.  The vendor-specific prefix <bcp14>MUST</bcp14> be a domain name under control of the service or application that sets the property, but it need not resolve in the Domain Name System <xref target="RFC1034"/> and <xref target="RFC1035"/>.  The prefix <tt>ietf.org</tt> and its subdomain names are reserved for IETF specifications.  The name <bcp14>MUST NOT</bcp14> contain the <tt>TILDE</tt> (U+007E) and <tt>SOLIDUS</tt> (U+002F) characters, as these require special-escaping special escaping when encoding a JSON Pointer <xref target="RFC6901"/> for that property.

        Vendor-specific properties <bcp14>MAY</bcp14> be set in any JSContact object.  Implementations <bcp14>MUST</bcp14> preserve vendor-specific properties in JSContact data, irrespective if they know their use.  They <bcp14>MUST NOT</bcp14> reject the property value as invalid, unless they are in control of the vendor-specific property as outlined in the above paragraph.
      </t>
      <t>The ABNF rule <tt>v-extension</tt> formally defines valid vendor-specific property names. Note that the vendor prefix allows for more values than are allowed as Internationalized Domain Names (IDN) (IDNs) <xref target="RFC8499"/>.  This is to allow target="RFC8499"/>; therefore, JSContact implementations can simply validate property names without implementing the full set of rules that apply to domain names.</t>

As of this writing, a <xref target="I-D.ietf-uuidrev-rfc4122bis">revision</xref> of the Universally Unique Identifier (UUID) Standards Track document <xref target="RFC4122" format="default"/> is in progress and will likely introduce new UUID versions and best practices to generate global unique identifiers.  Implementors <bcp14>SHOULD</bcp14> follow any recommendations described there.  Until then, implementations <bcp14>SHOULD</bcp14> generate identifiers using the random or pseudo-random pseudorandom UUID version described in <xref target="RFC4122" section="4.4"/>.</t>

<!--[rfced] Titles for Figures 30-32

a) May we remove the postal addresses from the titles of
Figures 30 and 31 to make them more concise? If so, may we list
the addresses in the text above the figures as shown below?

Original:
Section 2.5.1.1
   The following example illustrates the use of the address property.
   Additional examples are in Section 2.5.1.3.

   Figure 30: Example of the address "54321 Oak St, Reston, CA 20190, USA"

Section 2.5.1.3
   The following are examples of addresses, in addition to Figure 30.

   Figure 31: Example of the address "46, 1 Sukhumvit 51 Alley,
              Khlong Tan Nuea, Watthana, Bangkok 10110, Thailand"

Perhaps:
Section 2.5.1.1
   The following example illustrates the use of the address property for
   "54321 Oak St, Reston, CA 20190, USA". Additional examples are shown
   in Section 2.5.1.3.

   Figure 30: Example of an Address in the USA

Section 2.5.1.3
   The following example illustrates the use of the address property for
   "46, 1 Sukhumvit 51 Alley, Khlong Tan Nuea, Watthana, Bangkok 10110,
   Thailand". See Figure 30 for an additional example.

   Figure 31: Example of an Address in Thailand

b) FYI: We removed the section mention (Section 2.7.1) from the title of
Figure 32 and placed it within the added text above the figure as shown
below. Please let us know of any concerns.

Original:
Section 2.5.1.3
   Figure 32: Example of an address in Tokyo and its localization
              Section 2.7.1 in Japanese.

Current:
   The following example illustrates the use of an address in Tokyo and
   its localization (Section 2.7.1) in Japanese.

<!-- [rfced] We have included some specific questions about the IANA
text below. In addition to responding to those questions, please
review all of the IANA-related updates carefully and let us know
if any further updates are needed.

a) FYI: In Section 3.5.1, we placed the "Reference or Description" entry
below the "Change Controller" entry to match the order of the template
at https://www.iana.org/assignments/jscontact/.

b) In Sections 3.5.1, 3.6.1, and 3.7.1, may we update the definition of
"Change Controller" as shown below to make the text parallel with the
other entries?

Original:
   Change Controller:  This is who may request a change to this entry's
      definition (IETF for RFCs from the IETF stream).

Perhaps:
   Change Controller:  Person or entity responsible for requesting a
   change to the entry's definition (IETF for RFCs from the IETF stream).

c) In Sections 3.5.1, 3.6.1, 3.7.1, and 3.7.2:

- Is "Table 1" the correct reference in the sentences below (note that
there are 4 instances of each sentence)? Table 1 displays values from
the "JSContact Version" registry, not the "JSContact Enum Value" registry.
Please let us know if an update is needed to the registry name and/or the
table number.

Original:
   The version MUST be one of the allowed values of the version property
   in the JSContact Enum Value registry (see Table 1).

   The Until Version value either MUST be not set, or one of the allowed
   values of the version property in the JSContact Enum Value registry
   (see Table 1).

d) In Section 3.5.2 (Table 2):

- Note that the content of Table 2 in the PDF output is cut off rather
than wrapping. We have opened an issue for this. Please see
<https://github.com/ietf-tools/xml2rfc/issues/1110>.

- As Table is 2 characters past the 72-character limit, may we reformat
the table to fit by removing the Ref column and linking each section
number to the corresponding Property Context? For an example of the output,
see <https://www.rfc-editor.org/authors/rfc9553-table.pdf#table-2>.

- FYI: We have moved the entry for the "version" property name to appear
above "year" so that it appears in alphabetical order. Please let us know if
you prefer the previous order.

- FYI: Under "contexts", "label", "pref", and "uri", we ordered
Section "1.4.4" first in the Reference column since this section
corresponds to these terms. Please let us know if you prefer otherwise.

- Under the "@type" property name in the "References" column, should
references to Sections "2.5.1.2" and "2.2.1.2" be added for
"AddressComponent" and "NameComponent", respectively, or does Sections
"2.5.1" and "2.2.1" serve as the references for these terms?

If Sections "2.5.1.2" and "2.2.1.2" are used, should Sections "2.5.1"
and "2.2.1" also be updated under the "AddressComponent" and
"NameComponent" entries, respectively, in Tables 2 and 4 for
consistency?

- Under "full" and "isOrdered", should "Section 2.5.1" be
"Section 2.5.1.1" instead for direct access to these terms?

- Under "phoneticScript" and "phoneticSystem", should
"Section 2.2.1" be "Section 2.2.1.1" instead for direct
access to these terms?

e) In Section 3.7.1, should the definition of "Reference" be added
after "Change Controller" to match the template at
https://www.iana.org/assignments/jscontact? Also, since "Initial
Contents" is not included in the template, should it be removed and
made into a separate paragraph?

f) In Section 3.7.2, should the definition of "Change Controller" be
added after "Until Version" to match the template at
https://www.iana.org/assignments/jscontact?

g) In Section 3.7.3:

- FYI: We have moved the "phoneticSystem" entry and table above the
"relation" entry and table so that it appears in alphabetical order.
Please let us know if you prefer otherwise.

- Should the following updates be made so that readers are taken directly
to the enum values?
    - In Table 6, should Section "2.5.1" be updated to "2.5.1.1"?
    - In Table 10, should Section "2.5.1" be updated to "2.5.1.2"?
    - In Table 17, should Section "2.2.1" be updated to "2.2.1.2"?

The registry policy for assignments that require the JSContact major version to change is Standards Action (<xref target="RFC8126" sectionFormat="comma" section="4.9"/>).  The registry policy for other assignments is Specification Required (<xref target="RFC8126" sectionFormat="comma" section="4.6"/>).</t>
        <t>The Designated Expert designated expert (DE) decides if a major or minor version change is required and assigns the new version to the <xref target="iana-version-registry">Version Registry</xref>. target="iana-version-registry">"JSContact Version" registry</xref>.  Version numbers increment by one, and a major version change resets the minor version to zero.  An assignment may apply multiple changes and to more than one registry at once, in which case a single version change is sufficient.  If the registry policy is Specification Required, then the Designated Expert DE may decide that it is enough to document the new assignment in the Description item of the respective registry.</t>

          <t>A new type name, property name name, or enumerated value <bcp14>MUST NOT</bcp14> differ only in case from an already registered already-registered name or value.</t>
        <t>For a common-use registration, the DE
	      is expected to confirm that suitable documentation is available to ensure interoperability.
		  The DE should also verify that
            the new assignment does not conflict with work that is active or already published within the IETF.</t>
          <t>The DE will either approve or deny the registration request and publish a notice of the decision
	    to the Calext WG mailing list or its successor, as well as inform IANA.  A denial notice must be
	      justified by an explanation, and, and in the cases where it is possible, concrete suggestions on how the
	        request can be modified to become acceptable should be provided.</t>

          <t>JSContact registrations dot do not get deleted; instead, items that are no longer believed appropriate for use are declared obsolete by a change to their "intended usage" "Intended Usage" field; such items will be clearly marked in the IANA registry.</t>
          <t>Significant changes to a JSContact registry item's definition should be requested only when there are
	    serious omissions or errors in the published specification, as such changes may cause
	      interoperability issues.  When review is required, a change request may be denied if it renders

      <name>Security Considerations</name>
      <t>Contact information is very privacy-sensitive. privacy sensitive.  It can reveal the identity, location and location, credentials information, employment status, interests and hobbies, and social network of a user.  Its transmission and storage must be done carefully to protect it from possible threats, threats such as eavesdropping, replay, message insertion, deletion, modification, and on-path attacks.</t>
      <t>The data being stored and transmitted may be used in systems with real-world consequences.  For example, a malicious actor might provide JSContact data that uses the name of another person but insert their contact details to impersonate the unknown victim.  Such systems must be careful to authenticate all data they receive to prevent them from being subverted and ensure the change comes from an authorized entity.</t>
      <t>This document only defines the data format; such considerations are primarily the concern of the API or method of storage and transmission of such files.</t>
      <section anchor="json-parsing" numbered="true" toc="default">
        <name>JSON Parsing</name>
        <t>The security considerations of <xref target="RFC8259" format="default"/> apply to the use of JSON as the data interchange format.
    </t>
        <t>As for any serialization format, parsers need to thoroughly check the syntax of the supplied data.  JSON uses opening and closing brackets for several types and structures, and it is possible that the end of the supplied data will be reached when scanning for a matching closing bracket; this is an error condition, and implementations need to stop scanning at the end of the supplied data.</t>
        <t>JSON also uses a string encoding with some escape sequences to encode special characters within a string.  Care is needed when processing these escape sequences to ensure that they are fully formed before the special processing is triggered, with special care taken when the escape sequences appear adjacent to other (non-escaped) special characters or adjacent to the end of data (as in the previous paragraph).</t>
        <t>If parsing JSON into a non-textual structured data format, implementations may need to allocate storage to hold JSON string elements.  Since JSON does not use explicit string lengths, the risk of denial of service due to resource exhaustion is small, but implementations may still wish to place limits on the size of allocations they are willing to make in any given context, to avoid untrusted data causing excessive memory allocation.</t>
      </section>
      <section anchor="uri-values" numbered="true" toc="default">
        <name>URI Values</name>
        <t>Several JSContact properties contain URIs as values, and processing these properties requires extra care.  <xref target="RFC3986" sectionFormat="of" section="7"/> discusses security risks related to URIs.</t>
        <t>Fetching remote resources carries inherent risks.  Connections must only be allowed on well-known ports, using allowed protocols (generally, just HTTP/HTTPS on their default ports).  The URL must be resolved externally and not allowed to access internal resources.  Connecting to an external source reveals IP (and therefore often location) information.</t>
        <t>A maliciously constructed JSContact object may contain a very large number of URIs.  In the case of published address books with a large number of subscribers, such objects could be widely distributed.  Implementations should be careful to limit the automatic fetching of linked resources to reduce the risk of this being an amplification vector for a denial-of-service attack.</t>
