  1. PNG: Databases - Virtual Observatory Prospective PNG

  2. Questions • What VO does/will bring in our field? • What services exist, what do we need? • What actions should be undertaken in the community? by the PNG? Prospective PNG

  3. Surveys Pointed observations Simulations Reference data Physical models Data analysis S/W Misc. methods (IS) Survey processing Consortium/individuals Journal publications Archives (more or less science-ready) Databases Services VO Interoperability layer Client tools -- science user VO: access to data and services Prospective PNG

  4. Surveys Pointed observations Simulations Reference data Physical models Data analysis S/W Misc. methods (IS) Survey processing Consortium/individuals Journal publications Archives (more or less science-ready) Databases Services VO Interoperability layer Client tools -- science user VO: access to data and services Transparent access to resources distributed throughout the world Prospective PNG

  5.

  6. Surveys Pointed observations Simulations Reference data Physical models Data analysis S/W Misc. methods (IS) Survey processing Consortium/individuals Journal publications Archives (more or less science-ready) Databases Services VO Interoperability layer Client tools -- science user VO: access to data and services Science user does not need to know about VO. The tools hide complexity. Prospective PNG

  7. Surveys Pointed observations Simulations Reference data Physical models Data analysis S/W Misc. methods (IS) Survey processing Consortium/individuals Journal publications goals, VO deals with standardisation Archives (more or less science-ready) Databases Services VO Interoperability layer Client tools -- science user VO: access to data and services To achieve these goals, VO deals with standardisation • Data format • Access protocols • Data models Prospective PNG

  8. What does exist, what is needed? • Access to the literature (ADS) • Access to published catalogues (CDS, Vizier) • Access to telescope archives (raw data, standard pipelines) • Classical (non-interoperable) http interfaces • Rare VO compliant services • Clients (~VO compliants): Aladin, DS9, … Prospective PNG

  9. What does exist, what is needed? • Better clients More knowledge discovery tools, visualization Prospective PNG

  10. What does exist, what is needed? • Better clients • Science-ready archives • Added science-value. • Like SDSS … • Need contribution of astronomers (science verification). • Reference data. • Observations/simulations Prospective PNG

  11. What does exist, what is needed? • Better clients • Science-ready archives • Thematic databases • Added science value • Like NED - HyperLeda • Required for multi-wavelength, multi-parametric studies • Issues of cross-identifications of the sources Prospective PNG

  12. What does exist, what is needed? • Better clients • Science-ready archives • Thematic databases • Modelling/analysis services • Online versions, VO-integrated, of codes written by astronomers (eg. population synthesis) • Physical modelling, data-analysis (to extract information from archives and databases) • Statistical tools Prospective PNG

  13. Requirements to Galactic -galaxies community • Do not overlook the efforts for software development • It is very expensive, it should be valorized • Promote better practices for S/W development • Share the codes, reuse them Prospective PNG

  14. Requirements to Galactic -galaxies community • Do not overlook the efforts for software development • Produce science ready archives • Data producers (observatories) do not have expertise/man-power to bring the data to the optimal level (as good as artisanal reduction). • Key issue for enhancing the scientific return of an instrument. • Responsibility of the scientific consortia supporting the instruments. • Archives of large simulations. Prospective PNG

  15. Requirements to Galactic -galaxies community • Do not overlook the efforts for software development • Produce science ready archives • Produce thematic databases • Cross-identification of several sources • Homogenisation of heterogeneous sources • Scientific expertise which cannot be included in the data-model Prospective PNG

  16. Requirements to Galactic -galaxies community • Do not overlook the efforts for software development • Produce science ready archives • Produce thematic databases • Produce modelling and analysis services • Integrate codes into VO services Prospective PNG

  17. Requirements to PNG • Instrument data archives, literature and catalogue distribution is not the responsibility of PNG (see observatories, CDS…) • Production and distribution of science-ready archives and thematic databases (science driven) is the responsibility of PNG. • Production of modelling/analysis services, and integration in the VO is the responsibility of PNG.
