Dear Working Group members, We invite you to submit your proposals for the Open Source Working Group session taking place during RIPE92 in Edinburgh, Scotland, and online, 18-22 May 2026. The open source working group session is currently scheduled for Wednesday, 20 May, from 09:00-10:30 (UTC+1). The deadline for proposals for our session is April 13. But we encourage you to submit your proposal earlier if possible. How to submit your talk: 1. Go to the RIPE 92 Call for Presentations page and click on "Submit a topic": https://ripe92.ripe.net/present/call-for-presentations/ . 2. Follow the instructions to set up an account on Pretalx. [1] 3. Important: When filling in the submission form, please pay attention to the dropdown menu under "Track". This is where you select "Open Source WG". Second, please fill in the "duration" field with the length you have in mind - that helps our planning. In general, each talk is 15-30 mins including Q&A (depending on how much time is needed). If you have an idea for the agenda and are not sure how/if you should do something, then feel free to contact us on opensource-wg-chairs@ripe.net to discuss the idea! Remote presentations are also possible. As always, we are planning to reserve some time at the end of the WG session for lightning talks. These short (5 to 10 minutes max) updates/talks are decided on the day before the WG session on a time/space available basis. No need to submit to us anything for lightning talks at this time, but you are welcome to do so.
