12. May 10, 2006IVOA-GGF Astro-RG WS 12 WS Goals R&D  Operational Systems –Data management for Huge data –Global Workflow mechanism –need global authentication/authorization Share Current Status of VO as a GOOD example of Data Grid Apps. Strengthen relationship between VOers and Grid experts toward secure VO systems
