Organizing loop: values → facts → action. This page handles the sourced facts.
Lens Workshop
Fork the facts, propose corrections with sources, merge the community's patches — by file, reproducibly, with no server owning the truth.
Git-for-data, for Values Commons. A lens (a domain's options × sourced facts) is just a file — so the
facts can federate like the values do. Correct a score, add an option, hand someone a
patch; anyone can
merge it and get the same result, with every change attributed and sourced. Nothing is uploaded. The Open Values Standard is the contract underneath it.
How federation-by-file works →
Patch contractScope one changeName the affected lens, option, criterion, edge, or source before changing the file.
EvidenceSource before scoreAttach a URL, date, dataset, or method note. Mark judgement as judgement.
DiffSmall reversible patchPrefer a narrow patch someone can inspect, merge, fork, or reject without mystery.
AttributionA label, not an accountAdd a human-readable author label and note; identity is optional, rationale is not.
