Data integration has been an important area of research for several years. However, such systems suffer from one of the main drawbacks of database systems: the need to invest significant modeling effort upfront. Dataspace support platforms (DSSP) envision a system that offers useful services on its data without any setup effort and that improves with time in a pay-as-you-go fashion. We argue that to support DSSPs, the system needs to model uncertainty at its core. We describe the concepts of probabilistic mediated schemas and probabilistic mappings as enabling concepts for DSSPs.
