[116.01] MOCHA/ISAIA: Building Blocks for Interoperability in a Virtual Observatory

Some basic building blocks must be put in place before we can realize the vision of a National or Global Virtual Observatory. MOCHA is a project that is building a prototype interoperability infrastructure for a Virtual Observatory. ISAIA is an effort that defines the astrophysics query profile to enables searches to networked astrophysics resources that have very different data structures. Both projects are funded by the NASA Applied Information Systems Research Program. We shall describe a joint demonstration by these two projects that involves four data centers: the Astronomical Data Center (ADC), the High Energy Astrophysics Science Archive Research Center (HEASARC), the Astronomical Digital Image Library (ADIL), the Space Telescope Science Institute (STScI); and the University of Maryland. We shall show how a positional query for astrophysical data in a region of arbitrary geometrical boundary can be carried out using these basic components. We shall also describe a scheme by which user software can be deployed to a data center to extend its services, and how the system will return to the researcher only the desired scientific results. This capability is very important for multispectral studies using the large all-sky surveys that reside in distributed data archives.
