1. WP3 – SA1 Service activities in support of deployment of IVOA protocols and standards
Christophe ARVISET, ESA

2. WP3-SA1 Objectives
Support the deployment of IVOA protocols and standards in Europe with the goal of increasing the amount of astronomical resources being accessible through the Virtual Observatory
Provision to the European Community a Euro-VO Registry of VObs resources
Service activities in support of the European Data Centres for the implementation of the IVOA standards and protocols for them to publish their data holdings to the VObs
Adaptation of the VObs tools to the evolution of existing IVOA standards and to the new standards that will be produced, and to take into account data providers’ feedback

3. WP3-SA1 Deliverables D3.1 Euro-VO Registry of Resources ESA Nov. 2008
Delivery in two steps:
. Formal delivery V0.1 Euro-VO Registry 13 January 2009
. Full registry available mid-March 2009
D3.2
Registry curation tools
Jan. 2009
Delayed, mitigation plan established
Christophe ARVISET, ESA

4. D3.1 Euro-VO Registry of IVOA Resources
D3.1 deliverable delivered on 13/01/2009
Euro-VO Registry V0.1 available
2 steps approach for Euro-VO Registry implementation
Final Euro-VO Registry setup by March 2009
Convert ESA-VO full Registry into Euro-VO Registry
Finalize migration to new IVOA Registry of Resources v1.1
Make it available from the Euro-VO web pages
Announce it at IVOA level and European level
Central Euro-VO Registry
Full IVOA searchable Registry of VO Resources
Euro-VO registry harvests all other European and worldwide (harvestable) registries
Euro-VO registry can be harvested by other European and worldwide registries
Christophe ARVISET, ESA

5. Euro-VO Registry Use Cases
Registering VO Resources
People / data centres can register VO resources directly into the Euro-VO central registry
Data Centre / National Projects can have their own publishing registries, register their VO resources in their own registry, which then get harvested into the Euro-VO central registry
People / data centres can register their own VO resources into their data centre / national project registries, which then get harvested into the Euro-VO central registry
Searching VO Resources
People / VO apps developers can search directly into the Euro-VO central registry
Data Centre / National Projects can search their own Registry
If this is an IVOA full searchable Registry
Content will depend if they also harvest the Euro-VO central Registry

7. Inserting new Resources Edit / Clone Resources

8. Search a Resource

9. D3.2 Registry Curation Tools
Goal : ensure the quality / curation of the VO resources into the Euro-VO Registry
Quality is propagated to other registries harvesting the Euro-VO Registry
Availability of curation tools for VO Resources initially planned by D3.2 January 2009
Review work going on in that area of curation utilities at European and IVOA level
Review list of VO resources which can be “curated” when inserted into the registry and define plan of actions
Development of the curation tools of VO Resources
Implementation of these tools into the Euro-VO Registry
Christophe ARVISET, ESA

10. Curation Tool Issues
WP3-SA1 work concentrated on Euro-VO Registry as 1st priority, which took longer than expected
Still no consensus within IVOA
Some initial discussion and work in 2003
Nothing really concrete since 2004
Need to re-schedule D3.2 deliverable
Christophe ARVISET, ESA

11. D3.2 New Schedule

12. Curate what ? The Registry Resource The Service Interface
Compliance with the XML schema
Minimal tags correctly filled out
Extra useful tags and information
The Service Interface
Compliance with the IVOA specs
Minimal metadata and parameters
Extra optional features and metadata
The Astronomical Data
Quality and quantity of metadata
Astronomical relevance or importance
Christophe ARVISET, ESA

13. Curation Tool - Features
Support for a maximum of IVOA specs
Curation of all aspects of a service :
Resource Record information
Service compliance to specs
Astronomical Data quality
Multiple output formats (Terminal, WebPage, Objects)
Possibility to write your own tests
Support for multiple platforms and OS
Minimum programming knowledge required
Various other use cases :
Specific validation tests of own services
Stress tests or batch processing of services
Programmatic access to Registry and services
Using various utility Java libraries in other projects
