SciDataCon 2018 will address the theme: The Digital Frontiers of Global Science. In a hyperconnected world where the internet is pervasive and web technologies are driving major changes in our lives, research has become more than ever before digital and international. Furthermore, the major societal and scientific challenges facing humanity in this digital age are profoundly global in character, requiring the participation of researchers from all countries and disciplines. The data revolution is also a major source of the scientific opportunities to address these issues but to realize these potentials the frontiers of science, data analysis and stewardship must be advanced. Likewise, the data revolution must be inclusive, benefiting all, and harnessing all energies: no parts of the world and no disciplines should be left behind.
