Document Lifecycle
  1. Obsolete

1. Introduction

The following proposal is for the formation of a Jabber Interest Group that will create a new conferencing protocol, as well as create additional functionality and standardize communications on top of said conferencing protocol.

2. Base conferencing protocol

The initial task of the Conferencing SIG will be to propose a Jabber Conferencing specification that will solve various problems which exist in the current "groupchat" specification. This specification is meant to be a foundation for additional functionality; it defines the framework needed to provide additional features, without requiring changes to the framework specification itself. There is also to be a certain amount of feature-negotiation included; the conferencing service can define what features can be declared for a room, both as optional and required client features for room participation.

The framework's scope consists of the following minimum functionality:

In addition to these basic functions, we can imagine numerous different types of conferencing features; for example, hidden rooms created on the fly for discussions between a Jabber user and their friends or co-workers, transports providing access to similar foreign systems such as IRC, additional client functionality such as shared-location (URL/Co-browsing) and whiteboarding, and so on. There might also be requirements for security levels (for instance, normal participant, moderator, and room admin). Additional information may also be conveyed to users about one another, such as a user's real Jabber ID. Room entry or participation within a discussion might also have restrictions on some systems.

The framework protocol is meant to provide a basis for designing these additional features. Some features, such as co-browsing, could be implemented entirely client-side; others may require significant logic within the conferencing implementation. In addition, some features may be optional for participation within a room, while other features could be required in order for a client to participate within a room.

3. Justification for new Conferencing protocol

While the current "groupchat" specification is rather simple to implement, it is rather inflexible and cannot easily be extended; specifically, it has the following disadvantages:

This new conferencing protocol will be designed to solve these problems.

Because of the prevalence of the existing "groupchat" specification for multi-user chats, a long conversion process is anticipated. A server implementation which supports both protocols will simply not allow "groupchat"-only clients to participate in rooms with required features.

4. Continuing Development

As listed above, there is a fairly large number of features that could be developed on top of a well-designed framework. The Conferencing SIG will first be established to develop a framework, with features mainly being compared against the framework for feasibility of implementation. After a proposal has been formalized as a specification, the SIG will become a group for discussing and proposing new features, and for formally specifying those features.

Appendix D: Relation to XMPP

The Extensible Messaging and Presence Protocol (XMPP) is defined in the XMPP Core (RFC 6120) and XMPP IM (RFC 6121) specifications contributed by the XMPP Standards 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 document 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.

Appendix E: Discussion Venue

The primary venue for discussion of XMPP Extension Protocols is the <standards@xmpp.org> discussion list.

Discussion by the membership of the XSF might also be appropriate (see <https://mail.jabber.org/mailman/listinfo/members> for details).

Errata can be sent to <editor@xmpp.org>.
