Description of Tasks

Reports

R01. Workflow

Report VO France Workflow activities to VOTECH

Standards

S01. Workflow Characterization

Apply Characterization to workflow use cases (cross work with DS6, F. Bonnarel)

S02. 2nd generation data access

IVOA 2nd generation data access (SIA v2)

• Staging, authentication, regional search, ...
• Prototyping

Prototypes

P01. UWS-PA

Connect the CDS framework for UWS to the job-execution code carried over from CEA v1. From this prototype, draft the specification for the UWS-PA interface. Develop the prototype code as a beta release, but expect the production release to occur in stage 7.

P02. CDS UWS Candidates

Identify and implement other UWS candidates at CDS

• Using the UWS REST binding framework
• Improvement of this framework and packing for distribution
• Collaboration with G. Rixon

P03. Access Logs

Cross the Aladin, Simbad and VizieR access logs (cross work with DS4, T. Boch)

• Extraction of scenarios
• Modeling of a first set of workflow use cases
• Propose an another way to access the services ?

P04. VirGO Plug-In

VO Integration of VirGO Plug-In

• generalize SIA and SSA access
• complement supported PLASTIC input/output messages
• AOI metadata support

P05. SSO

Single Sign On

• Delegation Server for VObs
• Authentication profile based on VOMS
• VOMS support (in one month first prototype)

Production

C01. VOSpace V1.1

In collaboration with ESAC, produce a production component implementing VOSpace 1.1. This component will also support the legacy AstroGrid-MySpace interface and will be an upgrade for sites already running MySpace.

C02. Registry

Make the registry component able to provide VOResource-1.0 documents and to accept registations using VOSI.

C03. Registry

Adapt the AR to query using VOresource 1.0.

C04. Registry

Adapt the CEA, Community, DSA and VOSpace components to register using VOSI.

C05. Community/REST

Simplify the code, replacing SOAPy interface with a RESTful one.

C06. Aladin workflow plugin

Finalize Aladin workflow plugin (based on JLOW)

C07. WS BP

Support for VO WS BP to 1.0, but depends upon VOSI

Studies

T01. VOSpace/iRODS

In collaboration with CDS, explore how to put the VOSpace-1.1 interface on iRODS.

• Test and evaluation (Jargon Java API), report at the IVOA interop in Trieste
• Collaboration with D. Morris and C. Qin concerning the VOSpace standards

T02. DSA

In collaboration with ESAC, combine the best features of DSA and DM Mapper.

T03. Community/VOMS

Incorporate VOMS.

T04. Community/MyProxy

Reimplement MyProxy interface in Java so that it can be built into the community web-application. If this is feasible it simplifies the community installation and operation considerable.

T05. Workflow Use Cases

Test the different use cases with other tools than AÏDA. Study the use with Taverna (discussion with K. Benson)

T06. VO WS BP REST

VO WS BP REST (collaboration with Norman Gray)

• Check existing implementations
• Identify possible interoperability problems
• Report at the IVOA interop in Trieste

T07. VOspace/gLite

• VOspace proxy for gLite Replica Manager
• Design - needs delegation
