VO Activities at the Harvard-Smithsonian CfA

Abstract.

This paper summarizes the VO activities at the Harvard-Smithsonian Center for Astrophysics (CfA). Cfa has expertise covering virtually all branches of observational astronomy and of astrophysical research, as well as data and information management (the Chandra X-ray Center - CXC, and the Astrophysical Data System - ADS). At CfA, we have a leading role in the US National Virtual Observatory (NVO) team for the development of the VO Data Model(s), in collaboration with the European Astrophysical Virtual Observatory (AVO). To this end, we are validating our design with a local prototype, which will federate the CfA data archives, starting with the X-ray (Chandra) and optical (Telescope Data Center - TDC) archives.
