We study a particular class of cost sharing games – "data games" – covering situations where some players own data which are useful for a project pursued by the set of all players. The problem is to set up compensations between players. Data games are subadditive but generally not concave, and have a nonempty core. We characterize the core and compute the compensation scheme derived from the Shapley value. We then compare it to the nucleolus. Although we use the term "data" our analysis actually applies to any good characterized by non rivalry and excludability.
