2. WP3 main objectives
WP3 organizes the activities necessary to distribute knowledge of the VObs framework among European data centres (Workshops and visits)
WP3-2 gathers feedback from the VObs framework implementation by data centres.
WP3 work plan
Organization of workshops on how to publish data into the VObs
On-site visit to data centres to help them to publish their data holding into the VObs

4. EURO-VO Workshop on how to publish data in the VO
D6 deliverable
ESAC, June 2007
Christophe Arviset (ESA), Paolo Padovani (ESO)

5. Workshop Organization
Geared towards data centres and large projects to acquire the knowledge and experience necessary to allow them to become "publishers“ in the VO.
Small data providers not excluded
Workshop announcement through
DCA Board and PCT (forwarded to National data centres)
EURO-VO mailing list
IVOA mailing lists
At previous EURO-VO workshop in March 2007

6. Workshop Programme
Parallel sessions about publishing data using existing tools within EURO-VO
Publishing catalogues
DSA (AstroGRID), SAADA (OV-France), DMMapper (ESA)
Publishing spectra
DALToolkit (ESA), MEX (ESO)
Publishing images
DALToolkit (ESA), SAADA (OV-France), MEX (ESO)
VOEvent transient data (AstroGRID)

7. Workshop Participants
Around 70 participants registered
Around 45 “real” data centres participants
Advisors, ESA VO, ESO “excluded”
Good target audience for a technical meeting
~45% were programmers,
~45% were system administrators
~10% were astronomers
Christophe Arviset (ESA), Paolo Padovani (ESO)

8. Workshop Participants Distribution
Note that some partners had organized “similar” national workshops (eg UK)
Some EC “outsiders” (link with WP6)
No real “large” projects
Several “small” projects, astronomers with their own data

10. Workshop evaluation All participants could participate to all sessions
All sessions material published on the DCA web pages
High proportion of participants were able to publish their data through VO protocols by the end of the sessions
Feedback from Advisors and Participants “on-the-fly” during the workshop at:
Offline individual questionnaire for participants requested after the workshop
See more details in WP3-2 presentations

11. EURO-VO Workshop on Astronomical Spectroscopy
and the VObs
ESAC, March 2007
Christophe Arviset (ESA), Paolo Padovani (ESO)

12. Workshop organization
Initially not planned in the DCA proposal, but already mentioned in the preliminary plan for cycle 1
Workshop announcement through
DCA Board and PCT (forwarded to National data centres)
EURO-VO mailing list
IVOA mailing lists
Workshop pages
Concluding remarks from DCA Board and IVOA Chair
Christophe Arviset (ESA), Paolo Padovani (ESO)

13. Workshop objectives Bring the community to the VO and
get the VO experts to listen to the community requirements
Main goal was to identify current and future needs of astronomical spectroscopy, and discuss how the Virtual Observatory concept and applications can fulfill them
Forum of discussion and interchange of experiences between astronomers and engineers active in the VObs, and astronomers with a specific expertise and involvement in astronomical spectroscopic projects – both from the observational and the theoretical side.
Christophe Arviset (ESA), Paolo Padovani (ESO)

14. Workshop Programme 5 sessions: Each session
Spectroscopic surveys,
VO standards and applications,
Spectroscopic tools and algorithms,
Photometry in the VO,
Access to laboratory databases and theoretical data.
Each session
Series of presentations by experts in the field (VObs or not)
Discussions
34 presentations, 20 posters
Proceedings being printed
Christophe Arviset (ESA), Paolo Padovani (ESO)

15. Workshop Participants
Great success !
116 participants
from 15 countries EC
US, Japan
WP6
4 IVOA Working Group Chairs
Good mixture between scientists and developers
Good mixture between usual VO people and other people

17. On-site Support to Data Centres
Christophe Arviset (ESA), Paolo Padovani (ESO)

18. Overview WP3 on-site support went slower than initially expected
More focus was given in workshops
Follow-up visits will come more naturally from the attendance to the workshop
DCA Board decided to work more on the census of data centres before advertizing actively the on-site visits
Web page detailing the list of WP3 visits of experienced VObs persons to data centres, national meetings or sites selected by partners:
Possibility to request on-site visit to WP3 leaders (ESA, ESO)

19. Support to uptake
NOVA activities concentrated on support to data centres in the implementation of the VObs access layer for their data holdings
OmegaCEN data centre
Access from AtroGrid software to Astro-Wise archives
CNRS EuroVO-DCA staff is supporting the uptake of the theory draft standards in theory services in close connection with the CNRS WP4 activities
Christophe Arviset (ESA), Paolo Padovani (ESO)

20. WP3 overall conclusions
Successful workshop to help data centres to publish their data holdings into the VObs framework
Next major workshop (D7) to be held at ESO in June 2008
Special efforts will be made to involve also ”important” archives and large astronomical facilities, selected through IST, DCA census of data centres, EURO-VO SAC and through the ASTRONET project
Successful focus workshop on astronomy and the VObs
Good synergy between the VO and the Community
More work to be planned for the on-site visits to the data centres by VObs experts
Link to the census of data centres
Follow-up visits after the workshops
