Mark Finnane, ARC Laureate Fellow Griffith Criminology Institute, Griffith Uni I introduce the multi-jurisdictional, longitudinal criminal prosecutions project in Australia. I emphasise collaborative approaches to the design of research infrastructure, involving researchers, developers & data stakeholders; the value of citizen science to research; and the importance of digital and web technologies in making possible a new era of data-sharing for researchers and non-research communities of interest.
