The big catalogs coming from large surveys are ingested by computer scientists and astronomers. Added value The documentalists add relevant information like URL links to external applications, links to the Simbad database or to object from other VizieR catalogs. The documentalists add visualization output for associated data like the spectrum or incorporate images in the VizieR result page (ex CoRoT, Herschel). Catalog management at CDS ~ project support ~ VizieR provides access to the most complete library of published astronomical catalogs (data tables and associated data) available on line and organized in a self-documented database (12359 catalogs in may 2014). The VizieR search engine uses indexation based on several criteria which requires the expertise of scientists and documentalists to ingest each catalog. These meta-data go with an efficient position search engine adapted to big data. G. Landais, T. Boch, M. Brouty, S. Guehenneux, F. Genova, F. Ochsenbein, P. Ocvirk, E. Perret, FX. Pineau, AC.

Lesteven Observatoire Astronomique de Strasbourg, Université de Strasbourg/CNRS, UMR 7550 Catalog entry Catalog archived A data storage adapted to big surveys VizieR is involved in data dissemination coming from missions. The VizieR positional indexation is adapted to big volumetry : VizieR provides currently data coming from mission like 2MASS, SDSS, WISE which produces big volumetry. This efficient data access including crossmatching capabilities with other VizieR catalogs or with SIMBAD put the CDS as a partner of major projects like GAIA . VO dissemination The VOTable is a standard output available in VizieR and is recognized by VO-softwares like the Aladin image viewer (CDS) or the spreadsheet TOPcat (University of Bristol). The VOTable output is a XML format includind standardized definitions (UCD) which are included in the VizieR meta-data. The VizieR data and VizieR search capabilities (like to search by position in all VizieR) are fully accessible throught the VO. VizieR collaborations with space missions : VizieR is present in different steps of a mission : ●Collaboration with the Gaia project providing simulation GAIA catalog with all CDS capabilities. ●Collaboration with CoRoT to publish a catalog containing >300,000 time-series of exoplanets ●Provide a set of catalogs used by the XMM pipeline Take advantage of meta-data to compute photometry plots among ~2400 catalogs ~1000 filters This widget integrates three linked views: a zoomable plot with photometry points, a sky chart and the VizieR tabular data. The VizieR web application contains facillity like the all-sky viewer « Aladin Lite », links to external applications or easy tools (SAMP) to put data in a VO-application
