摘要：The Polar Data Centre of the National Institute of Polar Research has had the responsibility to manage the data for Japan as a National Antarctic Data Centre for the last two decades. During the International Polar Year (IPY) 2007–2008, a considerable number of multidisciplinary metadata that mainly came from IPY-endorsed projects involving Japanese activities were compiled by the data centre. Although long-term stewardship of those amalgamated metadata falls to the data centre, the efforts are in collaboration with the Global Change Master Directory, the Polar Information Commons, and the newly established World Data System of the International Council for Science.
