Talks

These are the XMPP related talks that will take place on the Decentralised Communication track. These talks will take place in room AW1.126 on Sunday, January 31st, 2026. You can also join the conversation or watch the live videos at aw1126.

• Engineering XMPP Federation: Building Messaging, Voice & Social Features Across Independent Projects: The XSF is a standards body that sits at the core of a development ecosystem of independent implementations by different individuals and organizations that actually work together, all highly interoperable, shipping new features at a high pace. This talk, by Jérôme Sautret will share how things work at this scale and will be co-presented by a server and client developer, showing how they work together to fine-tune their implementations. This talk starts at 13:15 and ends at 13:45 hs. (UTC+1:00)
• Movim: Building a Decentralized Social Network on XMPP: In this talk, Timothée Jaussoin will present how Movim leverages the XMPP standard and its extensions to deliver features users expect from modern social platforms (communities, IM, group chats, video calls, blogging and a complete publishing platform into a unified experience), without giving up your data to a centralized platform, while remaining fully federated, interoperable with other XMPP clients like Conversations and Dino, and capable of bridging to centralized platforms like Discord, Telegram, and WhatsApp!. This talk starts at 13:45 and ends at 14:15 hs. (UTC+1:00)
• What are you listening to now?: Implementing “Now Playing” feature in modern XMPP: In this talk, Özcan Oğuz will share the journey on his research on implementing this feature in modern XMPP clients, the protocols of certain operating systems to read the currently playing media, the current status of the support of XEP-0118 (User Tune) and the PoC of a modern “Now Playing” feature. This talk starts at 14:15 and ends at 14:45 hs. (UTC+1:00)

What to expect

• The chance to meet and engange in face to face conversations with the developers of the XMPP client that you use, the server that you may be selfhosting, the libraries and/or tools that you may be using in your project.
• Promotional and informational material: XMPP 2025 highlight Flyers, DI.DAY for XMPP Flyer …
• Free candy!
• And .. say what? Sticker? You are in for a treat! XMPP logo stickers, OMEMO, Movim, Dino, Monocles Chat, Conversations IM, Libervia, … you name it! ( And who knows? Maybe somebody will even be there presenting the new mascot for their project!! ).
