Data management is becoming increasingly social. We observe a new form of information in such collaborative scenarios, where users contribute and reuse information, which resides neither in the base data nor in the schema information.

We argue that this triad of data, schema, and higher-order structure requires new data ions that – at the same time – must efficiently scale to very large community databases. In addition, data generated by the community exposes four characteristics that make scalability especially difficult: (i) inconsistency, as different users or applications have or require partially overlapping and contradicting views; (ii) non-monotonicity, as new information may be able to revoke previous information already built upon; (iii) uncertainty, as both user intent and rankings are generally uncertain; and (iv) provenance, as con...
