The Extensible Messaging and Presence Protocol (XMPP) is defined in the XMPP Core (RFC 3920) and XMPP IM (RFC 3921) specifications contributed by the Jabber Software Foundation to the Internet Standards Process, which is managed by the Internet Engineering Task Force in accordance with RFC 2026. Any protocol defined in this JEP has been developed outside the Internet Standards Process and is to be understood as an extension to XMPP rather than as an evolution, development, or modification of XMPP itself.
The keywords "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119.
It is widely acknowledged within the Jabber/XMPP community that the vcard-temp [1] specification (JEP-0054) has outlived its usefulness. There are several reasons for this conclusion:
Given the weaknesses of vCard, there is interest across the broader Internet community in replacing vCard with something more modern and extensible. Unfortunately, no other standards development organization has developed an alternative to vCard. Part of the challenge is that quite detailed ontologies have been developed that might replace parts of the vCard specification (e.g., the Extensible Name and Address Language [4] developed by OASIS [5]) while less-formal ontologies are being used to represent other parts of the problem space (e.g., Friend of a Friend (FOAF) [6]). The relevant protocols are in flux and it is unclear when (or even if) stability will emerge.
Because of the unsettled landspace and the strong desire within the Jabber/XMPP community to move beyond JEP-0054, this JEP specifies a consistent framework for the wire representation of profile data fields in terms of the Data Forms [7] protocol, further qualified using the standardization concepts specified in Field Standardization for Data Forms [8]. The rationale behind this design decision is provided below.
Note: This JEP does not offer solutions to the problems of publishing, storing, and retrieving profile data. Those issues will be addressed in a separate proposal.
This JEP addresses the following requirements:
As noted, this JEP does not offer solutions to the problems of publishing, storing, and retrieving profile data. Those issues will be addressed in a separate proposal.
There are many possible approaches to representing profile data for communication over XMPP networks, including the following:
Structured data formats, such as User Geolocation [10] and User Physical Location [11].
Such data formats have the advantage of being human-readable. However:
A format represented by means of Resource Description Framework [12].
An argument could be made that RDF is a reasonable approach for representing profile data for communication over the XMPP network; however, such an argument will not be made in the current proposal. The author has considered RDF and has concluded that there are several reasons why RDF is undesirable as an XMPP wire protocol:
A format represented by means of Infobits [14].
The infobits approach to representing profile data was deprecated in early 2004 because it provides few advantages over an approach based on Data Forms.
A format represented by means of Data Forms (JEP-0004).
The Data Forms protocol defined in JEP-0004 has several advantages for use over XMPP:
For these reasons, this proposal specifies a way to represent profile data in terms of the Data Forms (jabber:x:data) protocol.
This proposal specifies that profile data shall be scoped by a FORM_TYPE of 'http://jabber.org/protocol/profiledata', in accordance with the field standardization methods defined in JEP-0068. For the sake of interoperability, profile data fields that will be in common use SHOULD be registered with the Jabber Registrar [15] (although they may or may not be defined in a Jabber Enhancement Proposal). Profile data fields that are intended to be used only within the context of a specialized application MAY remain unregistered, but unregistered fields MUST begin with the string "x-" in accordance with Section 3.4 of JEP-0068. [16]
The following is a simple and incomplete example of profile data represented via the Data Forms protocol, containing two registered data fields and one unregistered field:
<x xmlns='jabber:x:data' type='submit'> <field var='FORM_TYPE' type='hidden'> <value>http://jabber.org/protocol/profiledata</value> </field> <field var='common_name'> <value>Peter Saint-Andre</value> </field> <field var='nickname'> <value>stpeter</value> </field> <field var='x-favorite_painters'> <value>Joaquin Sorolla</value> <value>Jan Vermeer</value> </field> </x>
By specifying that all fields are scoped by a FORM_TYPE of 'http://jabber.org/protocol/profiledata', this proposal does not mean to imply that all profile data will or should be gathered in one data form. In reality, most such data will probably be gathered at the time of registration either at a website or via a "wizard" interface that breaks the process into smaller bundles (such as "Basic Personal Data", "Physical Location", "Internet Addresses", "Hobbies and Interests", and "Favorite Things"). The use of one FORM_TYPE is simply meant to scope the data fields so that each field is unique within the context of profile data. Any form that uses these fields along with a FORM_TYPE of 'http://jabber.org/protocol/profiledata' is of the "profile type" (i.e., is a specific instance of that type), which does not limit the number of forms that can be of that type.
However, scoping all data fields with a single FORM_TYPE implies it is necessary to define separate data fields for similar kinds of information. For example, the vCard specification (RFC 2426) defines "types" for certains kinds of data, such as email addresses, telephone numbers, and physical addresses, making it possible to specify that a telephone number corresponds to a fax machine or mobile phone or that a physical address corresponds to one's home or work location. In the Data Forms representation, any desired piece of information (e.g., work phone) must be represented with a separate data field.
In order to address most (if not all) of the pieces of information described in existing profile specifications, this JEP defines a great number of data fields. Even so, the data fields specified herein are not exhaustive, and it is expected that additional fields will be registered in the future through the mechanisms specified in the Jabber Registrar Considerations section of this JEP.
The following subsections specify common fields for defining various aspects of a person, which shall form the initial submission to the Jabber Registrar; many of these fields map to elements specified in vCard, LDAP (see RFC 2252 [17], RFC 2256 [18], and RFC 2798 [19]), xNAL, FOAF, and other existing specifications.
Mappings are provided to vCard, xNAL, and FOAF.

9. The extensibility requirement is critically important, because it would be best if the protocol specified herein could be used to represent data used within specialized communities. Examples of such communities include dating services, multiplayer gaming networks, IM services provided by portals and ISPs, and expert-location systems within large corporations. While such communities might use part or all of some common set of data fields (such as fields that map to familiar vCard elements), each community might also want to represent quite disparate kinds of information (dating criteria, favorite games, contact preferences, areas of expertise, and the like). Furthermore, data might be used to profile network actors that are not persons (e.g., bots, services, and other software agents). Therefore, the ideal proposal will provide an extensible framework for representing profile data and will not limit itself to representing the relatively small set of data fields covered by the vCard format.
