F. Genova, CDS Council meeting, 2004/09/9-101 Strategy

F. Genova, CDS Council meeting, 2004/09/9-102 Main drivers of CDS activity The CDS role in the international and national landscape

F. Genova, CDS Council meeting, 2004/09/9-103 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, 2004/09/9-104 Reference, value-added services

F. Genova, CDS Council meeting, 2004/09/9-105 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, 2004/09/9-106 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, 2004/09/9-107 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, 2004/09/9-108 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, 2004/09/9-109 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 : test the usage of PC cluster for queries to large catalogues and image transformation functions

F. Genova, CDS Council meeting, 2004/09/ 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/ 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/ 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/ 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/ 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
