30 years after the advent of the World Wide Web, information and communication technologies keep triggering deep changes in the way we access, produce and use knowledge. The convergence between data warehouse facilities and computational science heuristics is populating the Internet with cloud infrastructures designed to manage and process information in completely new ways. We are facing the emergence of a new generation of online platforms integrating knowledge management, data analytics, visualization and collaboration tools for purposes that gradually move from information retrieval to scientific research. This Chapter introduces the looming of the platform era in the legal world showing, also by means of concrete examples, how these tools can be used to make the most of the growing amount of legal information today accessible online. The analysis becomes an opportunity to dwell on how computational tools can turn into the emergence of new perspectives in legal research and practice.
