The CDS information services in the VO era: a status report

The new context of the on-going efforts towards an international Virtual Observatory has a significant impact on current CDS developments. While a strong emphasis remains on data quality, and permanent update of databases, new tools and additional links are being brought forward through collaboration to the AVO consortium, and with NVO and other VO efforts. We will present the current status of the three core services at CDS: the VizieR database of catalogues and tables; the SIMBAD reference database of astronomical objects; the ALADIN interactive sky atlas. Among the specific new features are: a systematic revision of data related to bright galaxies in SIMBAD (collaboration with the LEDA team); new large surveys available through VizieR, as well as additional archive and mission logs; new sets of digitized images (end of DSS-II, new ESO-R digitizations, etc.) available through Aladin. We will show how the increased interoperability (see Genova et al., this meeting) between CDS services, as well as with many external databases and archives, concurs to provide the users with a global view of all multi-wavelength observations available for a given field, a given object, or a given set of objects.
