The AVO to EURO-VO Transition

摘要

The Astrophysical Virtual Observatory (AVO) initiative, jo-intly funded by the European Commission and six European organisa-tions, had the task of creating the foundations of a regional scale infras-tructure by conducting a research and demonstration programme on theVO scientific requirements and necessary technologies. The AVO projectis now formally concluded. I highlight AVO's main achievements andthen describe its successor, the EURO-VO project. With its three new interlinked structures, the Data Centre Alliance, the Facility Centre, andthe Technology Centre, the EURO-VO is the logical next step for thedeployment of an operational VO in Europe.
