The problem of managing large volumes of information is of fundamental importance to modern society. In the last few years, we have developed and studied different technologies for storing, publishing, exchanging and querying large volumes of data. In particular, we have developed, studied and implemented general purpose query languages for the Web of data, which allow users to express queries in a simple and declarative way.
