摘要：Diverse data accumulated by many science projects make up the most significant legacy of the International Polar Year (IPY 2007-2008). The Polar Data Center (PDC) of the National Institute of Polar Research (NIPR) has a responsibility to manage these data for Japan as a National Antarctic Data Center (NADC) and as the World Data Center (WDC) for Aurora. During the IPY, a significant number of multidisciplinary metadata records were compiled from IPY endorsed projects with Japanese activity. A tight collaboration was established between the Global Change Master Directory (GCMD), the Polar Information Commons (PIC), and the newly established World Data System (WDS).
