  1. Strategy F. Genova, CDS Council meeting, 2004/09/9-10

  2. Main drivers of CDS activity • The CDS role in the international and national landscape F. Genova, CDS Council meeting, 2004/09/9-10

  3. activities • Reference, value-added services Contents/software development/operations Selected, validated, homogenized information from publications, catalogues, images + links • Standards and generic tools • Technological watch, R&T • User and project support F. Genova, CDS Council meeting, 2004/09/9-10

  4. Reference, value-added services F. Genova, CDS Council meeting, 2004/09/9-10

  5. Services (1) Different aspects • Building the contents Selection, validation, homogenisation of information from many sources • Building data management systems and user interfaces • Keep up with scientific and technical evolution F. Genova, CDS Council meeting, 2004/09/9-10

  6. Services (2) The basic CDS service to the community A high impact activity A long term, constantly evolving, very demanding activity which relies on experts (documentation, software, astronomers) F. Genova, CDS Council meeting, 2004/09/9-10

  7. The key for success • A highly skilled and motivated team integrating astronomers, ‘documentalists’ and computer engineers This implies in particular: • Careful integration of newcomers • Continuity in expertise essential: fill the holes (departures and retirements) in advance • Maintain the quality and team spirit while the team is renewed/growing F. Genova, CDS Council meeting, 2004/09/9-10

  8. Organization • The most demanding task at CDS among many (strong operational pressure on individuals and difficult work) • Not easy to homogenize long term activities (contents) with shorter term ones (projects) • Distributed team (Strasbourg, Paris, astronomers in Montpellier, Toulouse) • Take better into account the long term aspects • Specific ‘Bibliography’ team meetings • Encourage the staff to meet regularly to discuss difficult cases (already done in Paris on a weekly basis) • More generally, one need to revisit the CDS organigram F. Genova, CDS Council meeting, 2004/09/9-10

  9. In the short/medium term future:infrastructure • Increase the local computing power to support • Multi-criteria queries to VizieR • Image mosaicking in Aladin • Image analysis tools (IDHA/MDA) i.e. transport results and not data 2003-2004: test the usage of PC cluster for queries to large catalogues and image transformation functions F. Genova, CDS Council meeting, 2004/09/9-10

  10. In the short/medium term future:contents (1) • New update methods with the new SIMBAD s/w • Still increase integration with journals • Object tagging (A&A, also AAS), automated recognition of object names BUT quality must be preserved • New tools for the CDS bibliography team (also for users!) • Aladin astrometric registration (X,Y coord.) and centroide estimation (done) • Generalized Sesame (SIMBAD + VizieR - done) • Improve cross-id tool (‘raccord’) F. Genova, CDS Council meeting, 2004/09/9-10

  11. In the short/medium term future:contents (2) VizieR and Aladin • Continue to implement large surveys and reference image data sets in the local databases e.g SDSS • Efficient indexing • Better Metadata homogenization • More functionalities available (compression, mosaicking) • Improve access to distributed, heterogeneous data, taking advantage of VO development F. Genova, CDS Council meeting, 2004/09/9-10

  12. In the short/medium term future:functionalities (1) Beyond query by position: ‘VO-type queries’ • Multi-criteria searches in large surveys A R&T project: Indexing, usage of a PC cluster • Data selection, transformation (semantics) • UCD1+ in VizieR • Filters • Data model (e.g. hierarchical view of data sets) • Cross-match in VizieR & Aladin (incl. very large data sets) F. Genova, CDS Council meeting, 2004/09/9-10

  13. In the short/medium term future:functionalities (2) More tools, integrated and ‘collaborating’ • Integrated table visualisation tool Continue collaboration with the Indian VO team (Pune) • Links to external, useful tools ExtApp in Aladin e.g. Sextractor, image analysis tools (IDHA/MDA), … F. Genova, CDS Council meeting, 2004/09/9-10

  14. New functionalities • Identifiy new desirable functionnalities by evaluating science needs (anticipate new large projects, demos, VO projects RSCs), e.g. • Spectral Energy Distribution • ‘Multiview Aladin’ • HEALPIX in Aladin for cosmologists • Collaboration with IMCCE • More generally time dimension F. Genova, CDS Council meeting, 2004/09/9-10

Genova, CDS Council meeting, 2004/09/9-10

  39. R&T actions at CDS • Staying at the forefront of technologies and methods is critical for long term presence of CDS at the proper technical level and for keeping the services at the leading edge • New technologies implementation not too early, not too late! E.g. XML, Java • Decision after assessment and ‘strategic’ discussion about the discipline technical context F. Genova, CDS Council meeting, 2004/09/9-10
