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

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 Christophe ARVISET, ESA

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

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 http://registry.euro-vo.org/ 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

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 Christophe ARVISET, ESA

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

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

D3.2 New Schedule Christophe ARVISET, ESA

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

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 Christophe ARVISET, ESA
