Abstract: A Virtual Observatory is to be a scientific facility that embraces a very heterogeneous set of astronomical information. Such information includes Data and Knowledge. Data, covering the whole electromagnetic spectrum taken both from space and ground based telescopes, includes both raw and processed datasets such as astronomical catalogues and databases (NED, SIMBAD, Vizier, LEDA, GSC2, etc.), archival data, both of survey missions (IRAS, SLOAN, DSS, ROSAT, etc.) and of pointed missions (HST, VLT, ISO, XMM, ROSAT, etc.), and publications (ADS, ASTRO-PH, etc.). Knowledge includes any metadata, tool, or expertise associated with the description of the data such as instrument characteristics, exposure time calculators (ETC), simulators, etc. A Virtual Observatory study, such as the one funded by the European Commission, has to deal with such heterogeneity and complexity. The European Astrophysical Virtual Observatory study will concentrate on three specific topics: science drivers, interoperability and infrastructure. In these few pages we will focus on the interoperability aspect. Thanks to our ASTROVIRTEL experience, we will also try to identify some of the tools and standards that need to be conceived, designed, and implemented to allow a federation of data centres to function in a coordinated and integrated manner.
