2. Talk The Talk What is it? What are we trying to do? Focus: datacenters Focus: workflows Publishing data Using AstroGrid

3. What is AstroGrid? IVOA UK Effort: Prototype VO infrastructure for IVOA Produce working ‘ grid ’ UK datacenters ROE, Cambridge, JBO, MSSL, Leicester PPARC/IVOA Funded Approx 20 programmers + scientists ROE: Clive, John, Me, Peter. (+Bob, Andy) (+Mike, Nigel, etc) Finish by end 2004

4. What are we doing? Design Astronomical Grid Infrastructure Build a UK Astronomical Grid What ’ s a Grid? Components: Datacenter Registry MySpace Application Server ‘ Portal ’ User Interface Workflow – designer & executer Example: Brown Dwarfs

6. Datacenters Data publishing mechanism Web Services Queries

8. Datacenters Data publishing mechanism Web Services Queries Security Upload

9. Workflow Create: Flows, Sequences, Branches Save, Edit, Test Execute: Press button Go and drink coffee … … go on holiday …

10. Using AstroGrid Code-your-own: Web Service client toolkits Perl, Python, Java, etc – and FORTRAN! AstroGrid delegates (Java) Portal GUIs Combinations

11. Publishing Data Single download & install Connect to data … … depends on data! IVOA compatible … … when it happens Execute: Go on holiday

12. Challenges Agreeing standards … Completing ‘ critical mass ’ User acceptance Make sure it works Make sure it ’ s easy Provide more science

13. Summary UK effort: Influencing IVOA IVOA standards compatible Data publishing easier Greatly extends data available to astronomers Not quite a pipe dream: Data sets being published now
