In 2010, ICSU adopted, and has since implemented, a new World Data System (WDS) (link is external) which was created as a replacement for the WDC system. The WDS builds upon the 50-year legacy of the ICSU WDC and Federation of Astronomical and Geophysical data-analysis Services. Over 100 WDCs and Federation Services, as well as numerous other data centers, services and activities, have already expressed interest in becoming part of the new system. The WDS concept aims at a transition from existing stand-alone WDCs and individual Services to a common globally interoperable distributed data system that incorporates emerging technologies and new scientific data activities. The new WDS is built on the potential offered by advanced interconnections between data management components for disciplinary and multidisciplinary applications. ICSU has established a WDS International Programme Office (IPO) (link is external) hosted by the National Institute of Information and Communications Technology of Japan (NICT) (link is external). The WDS IPO will manage and coordinate the establishment and operations of the WDS, and take responsibility for outreach and promotional activities. The IPO will act under the guidance of the ICSU World Data System (link is external) Scientific Committee.
