IOSP is built on a single working principle: the people who depend on open science infrastructure and the people building it should be in the same room, working on the same problems, long enough to make real progress. This year, across the two main working days, we build 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 pieces of open science already exist. It's time they were woven into a coherent system.
