Description of Working Group
XMPP is an open, XML-based protocol for near real-time extensible messaging and presence. It is the core protocol of the Jabber Instant Messaging and Presence technology which is currently deployed on thousands of servers across the Internet and is used by millions of people worldwide. The XMPP working group shall adapt the XMPP for use as an IETF Instant Messaging and Presence technology.
The working group will use XMPP (as described in draft-miller-xmpp-*) as the basis of its work. The final specifications will be consistent as much as practical with both the requirements given in RFC2779 and the interoperability details in the final version of the CPIM specification (draft-ietf-impp-cpim). Note: If a requirement of RFC2779 or the final CPIM specification cannot be met, the working group will document why this requirement cannot be met.
A major goal of the working group will be to extend the current XMPP protocols to provide finished support for RFC 2779-compliant security mechanisms, including authentication, privacy, access control and end-to-end as well as hop-by-hop message security. Mandatory-to-implement security mechanisms will be specified as needed in order to guarantee secure protocol interoperability.
The working group shall also add support for internationalization and localization to XMPP.
Instant messaging differs from email primarily by requiring relatively short delivery latency guarantees and, typically, less robust transport service. In addition, instant messaging includes the notion of presence information so authorized users can determine if their correspondents are available.
BCP 41 will be the basis for working group consideration of the transport implications of the XMPP design with respect to network congestion.
Although not encouraged, non-backwards-compatible changes to the basis specifications will be acceptable if the working group determines that the changes are required to meet the group's technical objectives and the group clearly documents the reasons for making them.
There are facilities, such as chat rooms, shared white-boards and similar services that are not currently discussed in RFC2778 and RFC2779. When designing security mechanisms, the working group will keep in mind that XMPP may be extended or adapted to facilitate these additional services, so that design decisions can be made that will not preclude providing these services in the future.
