AstroGrid How to make your data famous OR One-click PhD creation
Talk The Talk What is it? What are we trying to do? Focus: datacenters Focus: workflows Publishing data Using AstroGrid
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
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
Datacenters Data publishing mechanism Web Services Queries
Datacenters Data publishing mechanism Web Services Queries Security Upload
Workflow Create: Flows, Sequences, Branches Save, Edit, Test Execute: Press button Go and drink coffee … … go on holiday …
Using AstroGrid Code-your-own: Web Service client toolkits Perl, Python, Java, etc – and FORTRAN! AstroGrid delegates (Java) Portal GUIs Combinations
Publishing Data Single download & install Connect to data … … depends on data! IVOA compatible … … when it happens Execute: Go on holiday
Challenges Agreeing standards … Completing ‘ critical mass ’ User acceptance Make sure it works Make sure it ’ s easy Provide more science
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
