IOSP 2026 in Leiden: build a community-owned open science system

The Institute of Open Science Practices <https://iosp.science/> is hosting
its 2026 workshops in Leiden from October 12 to 15, and we'd like you in
the room. *It's free to attend.*

Across the two main working days, the event will establish a
participant-owned data storage consortium, publish datasets, code, and
knowledge objects to it, create our own algorithms that assess the trust
and value of what's published, and assemble community-owned collaboratives
that route funding based on their interpretation of that analysis.

The result will be a fully functional open science system, owned by the
community that builds it, to test, build on, and iterate over the coming
months and years.

The pieces of open science already exist. It's time they were woven into a
coherent system.

You can already see the emerging data network here:

And the full workshop line-up is here:
https://iosp.science/workshops

Four ways to participate:

   1.

   *Register.* The room holds 100 people, and last year 425 registered for
   an 80-person room, so a registration isn't yet a seat and we confirm by
   email. The form asks whether you'd need travel support; say so if you would.

   2.

   *Contribute to the community track.* It runs alongside the main track on
   both working days and is an open space for talks, workshops, panels, and
   discussions around the four themes.

   3.

   *Building a tool? Submit it to the showcase.* We'll stress-test it and
   build on it in Leiden.

   4.

   *Join the resilient data workshop.* The workshop that opens IOSP 2026
   has you stand up an IPFS node and join a member-owned resilient data
   consortium. Your node will run either on your own laptop or on a Raspberry
   Pi kit you take home. There are only 20 seats and 10 take-home Raspberry Pi
   kits. Earlier sign-ups get first consideration if it fills. Signing up for
   this workshop also registers you for IOSP 2026.

And finally, spread the word. Forward this, post the community-track call,
or point a builder at the workshop or showcase.

*Hope to see you in Leiden!*

Jon, Ellie, and the IOSP organizing team

*P.S.* The resilient data consortium needs data worth keeping. If you know
a public dataset that could vanish—a shuttered project's archive, a
retiring server, data whose funding ended—recommend it and we'll consider
adding it to the network.
