Welcome to “perhaps the geekiest of all cooperative organizations on the planet!” The Data Commons Co-op . The co-op not only serves these communities, it is owned by them. The Data Commons Co-op, like a food or housing co-op, is owned by its members. The members have some fundamental differences, and many differences of emphasis and priorities. But like the Judean People's Front, the Judean Popular People's Front, the Campaign for a Free Galilee, and the Popular Front of Judea, they have a lot in common. This co-op is a way to share the cost of tending a commons of overlapping data, and realizing the benefits that brings to all.
