XMPP Extension Protocols

The XMPP Council worked to complete several primary tasks in its eighth session (2008-2009). A full accounting of work on Draft and Final XEPs for this session is located at


In June 2009 the Council was finally able to advance the core Jingle specifications from Experimental to Draft:

This effort represents a major milestone in the use of XMPP for multimedia session negotiation as originally deployed in the Google Talk application.


During recent instances of the twice-yearly XMPP Summit a significant topic of discussion has been improving the reliability of XMPP as a transport protocol (e.g., in mobile environments and distressed networks). The major result so far has been advancement from Experimental to Draft of XEP-0198: Stream Management (as well as advancement from Draft to Final of XEP-0199: XMPP Ping).

Draft to Final

The eighth Council made a concerted effort to advance more XEPs from Draft to Final in the XSF's standards process. The specifications so advanced were:

It is probable that additional XEPs will be advanced from Draft to Final during the ninth Council session (2009-2010).

XEP Maintenance

As is evident from the vote tallies for the eighth Council session, maintenance of existing specifications now consumes quite a bit of attention. This is an inevitable result of the fact that the XMPP protocol stack continues to grow year after year. Some concern has been expressed that this large maintenance burden might be taking away resources from development of new XMPP extensions. It is unclear yet how this issue can be addressed.

IETF Activities

The XSF has spearheaded creation of a renewed XMPP Working Group at the Internet Engineering Task Force (IETF).

The primary focus for the WG is to complete revisions to RFC 3920 and RFC 3921, which comprise the core definition of XMPP. This work is very far along and will likely be complete in late 2009 or early 2010.

A strong secondary focus for the WG is development of a secure, deployable technology for end-to-end encryption of XMPP traffic. A requirements document has been published (borrowing heavily from XEP-0210 and one proposed approach to solving the problem has been documented using an application-level profile of Transport Layer Security, called XTLS.


The XSF is not a traditional organisation attempting to sell a product or a service. It does however have an interest in raising the profile of and promoting XMPP with the aim of increasing the size of the XMPP development community. With this goal in mind, efforts are made to ensure that the XSF is represented at some industry events and that the XSF is presented as an active organisation.

Conference Presentations

XSF Members often give talks at industry events raising the profile of XMPP. During the period covered by this report two major events occured at which the XSF had an official presence. FOSDEM and OSCON.


The XMPP Room at FOSDEM was host to 9 XMPP-related talks, 8 by XSF Members and one by Simon Tennant of BuddyCloud:

  • XMPP 101 A Fast-Paced introduction to XMPP Technologies (Remko Tronçon & Peter Saint-Andre)
  • PubSub and the Web (Nathan Fritz)
  • Integrating XMPP into Web Technologies (Jack Moffitt)
  • Geolocation (Simon Tennant of BuddyCloud)
  • Deploying Jingle (Diana Cionoiu)
  • Personal Media Networks (Dirk Meyer)
  • Large-Scale XMPP Deployments (Florian Jensen)
  • XMPP in Real Life (Mickaël Rémond)
  • Presenting Information Flow in Deployed XMPP Clients (Dave Cridland)

Blog posts on some of these presentations (which were all very well attended) can be found on the XMPP Blog. The team also tried their hand at some commercial promotional activities at the XMPP Booth, giving away stickers and selling XMPP T-Shirts.

XMPP in the News

The large number of XMPP-related announcements and stories this year provided plenty of content for the regular XMPP Roundup blog posts authored by Nicolas Vérité and Peter Saint-Andre. Website
