The XMPP Standards Foundation (also known as the XSF and formerly the Jabber Software Foundation) is an independent, nonprofit standards development organisation whose primary mission is to define open protocols for presence, instant messaging, and real-time communication and collaboration on top of the IETF’s Extensible Messaging and Presence Protocol (XMPP).

The XSF also provides information and infrastructure to the worldwide community of Jabber/XMPP developers, service providers, and end users. In addition, the XSF administers the Jabber Trademark Licensing Program.

At the core of the XSF is its elected Membership who, in turn, elect a Council (the technical leadership) and Board (the business leadership). The Board also appoints various work teams and roles.

The Board

The Board of Directors of the XMPP Standards Foundation oversees the business affairs of the organisation. As elected by the XSF membership, the Board of Directors consists of the following individuals:

• Dave Cridland is an independent consultant for Extensible Messaging Ltd, working mostly on XMPP-based messaging things for a number of clients. This isn’t his first time on the Board, and he has been on the XMPP Council for a number of years as well. Will nobody ever learn? He has worked extensively on multiple XMPP server projects, including Isode’s M-Link, Ignite Realtime’s Openfire, and his own Metre project. His hobbies include working on XMPP servers, which is just as well, and writing about himself in the third person, which is really coming into its own right now. Drop him a message via XMPP.
• Edward Maurer is working in engineering automation (energy sector, non-XMPP) and is volunteering in XMPP since more than five years already. Since 2020 he is thriving the XSF Communication Team.
