The 4th International Open Data Conference (IODC) took place from the 6th - 7th October 2016 in Madrid, building on the lessons shared at the IODC 2015, and bringing together groups from across the world to discuss open data strategies, use and impact. This year’s gathering focused on “global goals, local impact”. PARIS21 was invited by Open Data Watch (ODW) to participate in a panel on “Openness in NSOs: A review of Needs and Available Tools and Methods” and advocated for National Statistical Offices (NSOs) to play a more central role in discussions around open data. The agenda of the event focused on the three main objectives of the Conference: 1.Bring together the most innovative and practical Open Data solutions that are driving social and economic impact on areas such as health, gender, cities, education, science, agriculture and many more. 2.Identify and explore both new opportunities and new debates that are shaping the Open Data agenda. 3.Consolidate an international partnership on Open Data able to drive the development of global common resources for the international Open Data community.
