What is it?
What are we trying to do?
Focus: datacenters
Focus: workflows
Publishing data
Using AstroGrid
What is AstroGrid?
IVOAUK Effort: Prototype VO infrastructure for IVOA Produce working ‘grid’ UK datacenters
ROE, Cambridge, JBO, MSSL, Leicester
PPARC/IVOA FundedApprox 20 programmers + scientists ROE: Clive, John, Me, Peter. (+Bob, Andy) (+Mike, Nigel, etc)
Finish by end 2004
What are we doing?
Design Astronomical Grid InfrastructureBuild a UK Astronomical Grid What’s a Grid?
Components: Datacenter Registry MySpace Application Server ‘Portal’ User Interface Workflow – designer & executer
Example: Brown Dwarfs

Workflow
Create:Flows, Sequences, BranchesSave, Edit, Test
Execute:Press buttonGo 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 acceptanceMake sure it worksMake sure it’s easyProvide more science
Summary
UK effort: Influencing IVOA IVOA standards compatible
Data publishing easierGreatly extends data available to astronomersNot quite a pipe dream: Data sets being published now
