12. Euro-VO Data Center Alliance

13. 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. • http://cds.u-strasbg.fr/twikiDCA/bin/view/EuroVODCA/WebHome • Organization: • Board (project coordinator: Françoise Genova) • PCT: Project Coordination Team (Project manager: Mathias Depretz) • IST: Internal Science Team members (chair: Mark Allen) • TEG: Theoretical astrophysics Expert Group members (chair: Gerard Lemson) • A number of Work Packages H. Wozniak / OV-France TVO workshop

14. Euro-VO DCA • Theory: • Theoretical astronomy Expert Group (TEG) • Pedro OSUNA (ESA) • Santi CASSISI (INAF) • Miguel CERVIÑO (INTA) • Gerard LEMSON (MPG, chair) • Joop SCHAYE (NOVA) • Nic WALTON (LU) • Hervé WOZNIAK (CNRS) • 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) H. Wozniak / OV-France TVO workshop

15. 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) H. Wozniak / OV-France TVO workshop

16. 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 • roadmap • cost estimates H. Wozniak / OV-France TVO workshop

17. Euro-VO DCA • 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) H. Wozniak / OV-France TVO workshop
