2nd Theoretical Virtual Observatory
workshop
OV-France
VO-France TWG
From IAP (April 2006) to Lyon (June 2007)
• Presentation of VO-France at ASSNA meeting (December 2003)
• First WG meeting just after the founding VO-France workshop (4-6 April
2005)
• Parallel session during Obernai winter school (5-7 November 2005)
• Joined ASSNA-ASOV workshop dedicated to TVO (5-6 April 2006)
– goals:
• Need to explain what is [not] Virtual Observatory
• Need to understand numerical simulations/codes specificity
• Need to see how a VO-compliant theoretical service could run and help to make
science
• Make an effort to adapt each others to different languages!

Information: Web of Theory Working Group
• http://www.france-ov.org/twiki/bin/view/GROUPEStravail/ObsVTheorie
• Need an update of ‘on-going projects’ section
– Necessary for a number of census (EURO-VO DCA, OV-France, etc.)
– Visibility of this activity for CNAP, CNRS/INSU etc.
– Need to include ‘theoretical spectra’ services ? (eg POLLUX)

Euro-VO Data Center Alliance
Euro-VO DCA
•
•
•
Funded by the European Community (FP6), starting in September 2006 for a
duration of 28 months (►end 2008)
Alliance of Data Centre communities represented at a national level.
DCA will:
–
–
–
–
•
•
coordinate and assist European Data Centres to take up VO standards
share best practice for data providers,
consolidate operational requirements for VO-enabled tools and systems
Enable the identification and promotion of scientific requirements from programs of
strategic national interest that require VO technologies and services.

– WorkPackage 4 dedicated to theory (led by G. Lemson)
• aims at assessing the inclusion of theory data and services in the Virtual Observatory.
• tackled by the TEG, which has yearly meetings and email discussions to establish a
framework for the inclusion of Theoretical Astronomy Services in the VObs.
• The TEG organizes a Workshop
– Strong links with WP5 (VO ↔ GRID)

Euro-VO DCA
• “Theory” census:
– theory specific questionnaire.
the TEG questionnaire is not only directed at theory data centers, but is meant to
gather feedback from astronomers (theorists *and* observers) in general on what
they expect from a "theory VO".
– send out questionnaire (end of June)
– deadline end of September
– TEG face2face meeting beginning October to interpret results and come up with
proposals
– write first draft of whitepaper, beginning of Dec 2007 to be discussed in ...
• Theory workshop
– with WP5-Grid in "month 17“ (January 2008)

Euro-VO DCA
•
White paper (outline):
1. Review work on "theory in the VObs" so far:
•
•
•
•
whitepaper Lemson & Colberg
IVOA Theory interest group (TIG)
existing census results/inventory
examples of concrete services, data sets published online, and VO-like
2. Gathering requirements
•
•
•
•
How: theory specific questionnaire as contribution to Euro-VO DCA census (extend to IVOA TIG) + existing census
results (if available)
Describe results of questionnaire
extract requirements from result
discuss what (if) is being done to address these
3. Proposals for actions to
•
•
IVOA
Euro-VO
–
–
–
•
VOTECH
DCA
FC
individual data centers
4. Gather feedback on expectations of feasibility for these proposals and what resources are required

• Impact on VO-France (theory only)
– Funding of 1 year of engineer to help SNAP+DM implementation on 3 “projects”:
– HORIZON DBs
– Besançon model
– VO-Paris (PDR, Titan, Dense cores DB etc.)
• Interviews on last Thursday
• Start on September?
– Update of theory census at French level (including all aspects of theory)
