AG2 Cycle01: Delivery targets

Now: software availableend Feb: v1.0 RC1

Downloadable packages New MySpace Deploy for testing

end March: v1.0 – full release (pre NAM) Initial AstroGrid deployment Stable code

end June: v1.1 – maintenance release Full deployment: all data, apps Identified bugs fixed or plan-to-fix On-ramps added to web UI

AG2/VOTech VOTech is Discovery (what is available, what can we

do) Evaluation (how does it work, will it fit) Prototyping (trial builds)

AstroGrid is Stabilisation (make it work predictably) Productisation (package for delivery) Deployment (make it available)

AG2/VOTech Who does what?

Still being worked out Most AstroGrid people will work on VOTech

Between 0% - 100% New hires ~3

Kick-off meeting last yearStarted Jan’05

VOTech: Initial prioritiesSecurity Single signon Authentication Service – service trusted invocation

VOSpace Agreed protocols Incorporate security sharing … Extend to databases, desktop

CEA Agreed protocols Extend to client

AG2 priorities: existingStabilise code Predictable fall-through Repeatable behaviour Fix bugs!

Refactor Where performance slow Where code is crap or convoluted

Package Registry + DAS + MySpace + JES Less critical:

Portal/Workflow, Community

AG2 priorities: newAstronomer’s Workbench Facilities

Tools framework Plugin ability

Evaluate alternatives under VOTech

Data access Extend to other databases, storage facilities Automated metadata generation Extend image, spectra … access

VODaX: workflow data exchange
