The European Data Forum (EDF) is a regularly scheduled (yearly) meeting place for industry, research, policy makers, and community initiatives to discuss the challenges and opportunities of (Big) Data in Europe. These aspects have both a technical (in terms of technology and infrastructure needed to master the volumes, heterogeneity, and dynamicity of Big Data), and a socio-economic component (speaking about emerging types of products and services and their commercialization, innovation and business models, but also policies and regulations).
