Four operational surfaces. One common system.
The Pledge, the Registry, AMPL, and the Commons Dataset. Each is useful on its own. Together they form the public infrastructure for consent-aware, provenance-rich AI. Each is being developed openly with partners across the AI, library, archive, and policy communities.
Why these four work together.
Each project is useful on its own, and each gets stronger when combined. The Pledge is the contribution gateway — the on-ramp through which institutions commit data and preferences into the commons. The Registry is the substrate where those commitments and the assertions about every artifact become citable. AMPL is the shared vocabulary that runs through every surface, so a pledge, an attestation, and a downstream use all speak the same language. The Commons Dataset is what becomes available to train on once the first three are in place.
For an institution preparing to comply with the EU AI Act, or for a research team that wants to build on data with clear provenance, the four together give a starting point. Adoption is open. Co-authorship of the next versions is invited.
