They will enable large-scale aggregation and sharing of computational, data and other resources across institutional boundaries. And harnessing these new technologies effectively will transform scientific disciplines ranging from high-energy physics to the life sciences.” Dr. Ian Foster, Co-leader GLOBUS Project P.Quinn TIVO June10-14 2002

17. VO Challenges AVO: the promise Bob Fosbury JENAM 2001 (1) To take the data collected by teams for specific projects and manage/massage it in such a way as to be of general use Comments - • If the data in an archive are neither well-calibrated nor well-described, they are of little value for the AVO • If the data are in good order, the AVO is unnecessary — it is just a layer of middle-men • If I were a funding agency, why should I support the ‘middle-man’ when I could fund the original science project? P.Quinn TIVO June10-14 2002

18. A VO RoadmapQuinn ADASS’01 • To address Bob’s comments the international VO effort needs to define a unified and astronomically accepted roadmap for the next three years • Without a publicly visible direction, accountability and receptiveness to requirements we will fail - • This roadmap must be in defined/produced by the next international VO meeting P.Quinn TIVO June10-14 2002

19. The International Virtual Observatory Alliance P.Quinn TIVO June10-14 2002

20. IVOA • IS NOT ANOTHER PROJECT • IS an alliance of existing and future national and international projects to • Define the common ground needed to make an operational and scientifically effective IVO • Reach agreement on standards and interoperability • Allow the international scientific communities resident in the national projects, and elsewhere, a global channel for comment, criticism and guidance P.Quinn TIVO June10-14 2002

25. An Invitation The ASTROGRID, AVO and NVO projects take the opportunity of the Munich VO meeting to formally announce the IVOA and would like to extend an invitation to all VO projects to join this alliance for the pursuit of an international virtual observatory and the expansion of astronomical research capabilities in the 21st century. P.Quinn TIVO June10-14 2002

26. ESO Archive Policy http://archive.eso.org/Archive_Access_Policy.html ESO is fully aware of the importance of international collaborations in achieving the scientific goals and break-throughs necessary for astronomy to advance in the 21st century. The scientific potential of facilities like ALMA and OWL will only be realized by coordinated international efforts and the free exchange of astronomical ideas and data. To this end, ESO is preparing to provide open international access to all its archival data. Before this can happen, the ESO data holdings must be of a uniform high quality, in a form appropriate for recalibration and archival research and be supported by adequate operational manpower. ESO is taking the lead in Europe in defining data quality and interoperability standards through its coordination and funding efforts for an Astrophysical Virtual Observatory. The aim of the AVO is to provide the European and global astronomical community with an archival and data handling resource that can meet the needs of 21st century astronomy. The AVO program aims to join data from ESO telescopes with space and ground archives from Europe in an AVO Phase A facility by the end of 2003. From this time, ESO data will start to become freely available to the international astronomical community in a phased manner, following standards for data centers in the global virtual observatory and the availability of new VLT instruments.
