Even for educational useAccelerate astronomical research, and sufficient time for research itself !! Virtual Observatory
Too hard to collect and analyze whole data.Need Cat’s help

Interconnected VOs in the World
Canada VO
February 20, 2006 JVO-AstroGrid Collaboration 12
Successful Interoperations
• Accesses from / to other VOs in Europe and US have been available since Dec 2004
• Publishing & Searchable Registries
• 140+ resources are accessible as of today

Workflow Description Language
Based on BPEL4WS
• Variable definition• Controls (Loop,
Condition)• Parallel execution• Invoke external
services• Invoke built-in Java

QSO searches
Such results can be obtained only in a few minutes

Future Prospects• Started to design / implement operational system
– More User-friendly interfaces– Add analysis engines by Java-wrapping– Single-Sign-on, authentication by Grid tool– Virtual file system as users area: VOStore– Download to / Upload from user machines– Science corresponding to use cases !!– Collaboration with large observatories (Subaru, ALMA)
• Experimental operation – March 2006 (hopefully)• Standardization of WFDL in IVOA• Technologies sharing in AP region (East Asia)
February 20, 2006 JVO-AstroGrid Collaboration 20
Wish List for Collaboration
• Workflow– Common effort to standardize WFDL in IVOA
• from JVO to AstroGrid– SkyNode tool kit
• from AstroGrid to JVO– MySpace toward VOStore– SSO if available
• Access to AstroGrid Registry
