  7. Project Approach • Agile: • iterative & incremental development • Open project: • Wiki http://wiki.astrogrid.org/bin/view/Astrogrid/WebHome • Forum http://forum.astrogrid.org/index.php • News http://news.astrogrid.org/index.php • Jabber via jabber.astrogrid.org • Open Source code • http://www.astrogrid.org/maven/build/index.html Astro-Wise meeting, Kapteyn Institute, Groningen

  8. Development Approach • Iterative • full cycle each iteration • 3 month(-ish) iterations • Incremental • add functionality each iteration • refactor wherever necessary • Use-case driven • from ‘key 10’ science cases • http://wiki.astrogrid.org/bin/view/Astrogrid/ScienceProblems • Architecture led • http://wiki.astrogrid.org/bin/view/Agdoc/ArchVision • http://wiki.astrogrid.org/bin/view/Agdoc/ArchOverview • http://wiki.astrogrid.org/bin/view/AG2/ArchitectureNotes Astro-Wise meeting, Kapteyn Institute, Groningen

  9. Technology choices • design : UML, TogetherSoft ControlCenter • development language : Java • Web services • source control : CVS • IDE/build/integrate : Eclipse/Ant/Maven • Java libraries: Apache • Portal : Apache Cocoon Astro-Wise meeting, Kapteyn Institute, Groningen

  10. VObs Structure • Component-based • can install any/all components • Decentralised • no single product nor centre • Service-based • web services Astro-Wise meeting, Kapteyn Institute, Groningen

  11. Components • Portal • Registry • Security • Community • Workflow • Data Access • MySpace • Applications Astro-Wise meeting, Kapteyn Institute, Groningen

  12. AstroGrid-2 • Aspects • Extension • Infrastructure • Grid (GT4+) integration • Intelligent resource discovery (semantic grid) • Additional components • Data exploration • Agents: eStar integration • Client-based access: VO Workbench •  Technical Scope • http://wiki.astrogrid.org/bin/view/AG2/TechnicalScope Astro-Wise meeting, Kapteyn Institute, Groningen

  13. AstroGrid-2 Layer Diagram Astro-Wise meeting, Kapteyn Institute, Groningen

  14. AstroGrid use • Portal  Workflow • Workflow is key to AstroGrid Astro-Wise meeting, Kapteyn Institute, Groningen

  15. Workflow • Sequence • Sequential steps • Flow • Steps executed in parallel • Step • Application/Tool, Data query • Configured via XForm specification • To be enhanced later • or Query form • Workflow definition • Subset of BPEL Astro-Wise meeting, Kapteyn Institute, Groningen

  16. Create Workflow Astro-Wise meeting, Kapteyn Institute, Groningen

  17. Add tools to steps Astro-Wise meeting, Kapteyn Institute, Groningen

  18. Configure step: data query Astro-Wise meeting, Kapteyn Institute, Groningen

  19. Configure step: tool Astro-Wise meeting, Kapteyn Institute, Groningen

  20. Submit workflow, Check status Astro-Wise meeting, Kapteyn Institute, Groningen

  21. Data query step • Insert valid ADQL (v0.7.?) • Assisted query builder this iteration Astro-Wise meeting, Kapteyn Institute, Groningen

  22. MySpace: virtual storage • Operations: • Copy, Delete, Move • Upload from file, URL • End-point • Multiple servers per manager • Usually hidden from user Astro-Wise meeting, Kapteyn Institute, Groningen

  23. eg Copy file, Upload file Astro-Wise meeting, Kapteyn Institute, Groningen

  24. Registry: Query Astro-Wise meeting, Kapteyn Institute, Groningen

  25. Registry details • Conforms to IVOA std • Extended: • ApplicationDefinition • AstroGrid CEA Astro-Wise meeting, Kapteyn Institute, Groningen

  26. Registry harvest • Admin function, so usually invisible Astro-Wise meeting, Kapteyn Institute, Groningen

  27. Itn05: Complex workflow: AVO Demo • Canned images • ACE • AstroGrid wrapping of SExtractor • VOTMerge • AstroGrid VOTable ‘federation’ • HyperZ • AstroGrid wrapping of HyperZ • CEA Astro-Wise meeting, Kapteyn Institute, Groningen

  28. Itn06: Jan 2005 AVO Demo • Build on the Itn05 tool • Image access (SIAP) • Add in extra redshift applications • Bpz • ANNz • Access wider data resources • WFS • GOODS plus IR • Deploy on 'real' machines • Disk • Compute Astro-Wise meeting, Kapteyn Institute, Groningen
