1 Data Resources and Services at Chinese Astronomical Data Center Chenzhou Cui, Boliang He Chinese Virtual Observatory (China-VO) National Astronomical Observatory of China

2 China-VO Virtual Observatory (VO) is a data-intensively online astronomical research and education environment, taking advantages of advanced information technologies to achieve seamless, global access to astronomical information. Chinese Virtual Observatory (China-VO) is the national VO project in China initiated in 2002 by Chinese astronomical community leading by National Astronomical Observatories, Chinese Academy of Sciences. China-VO became a member of the IVOA with the recommendation of Dr. Jim Gray China-VO Platform Unified Access to On-line Astronomical Resources and Services VO-ready Projects and Facilities VO-based Astronomical Research Activities VO-based Public Education R&D Focuses
