The winds of change
“Internet computing and Grid technologies promise to change the way we tackle complex problems. 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

What has this to do with astronomy?
• Astronomy has become a BIG international science– Gemini, VLT, ALMA, SKA, NGST, ELTs
• Astronomy projects involve– International coordinated research efforts – Distributed multi-wavelength teams, resources and
data – Data volumes with doubling times < 12 months
• Astronomy service organizations need to – provide their communities with access to software
tools, high quality raw and processed data in the face of desktop computing power and network bandwidths with doubling times > 18 months

The AVO Proposal• EU RTD Proposal submitted 15 February 2001 following
OPTICON recommendations for a European VO effort (similar effort in the US [NVO] proposed by Decadal Report)
• ESO PI (Quinn) + STECF(Benvenuti), CDS (Genova), TERAPIX (Mellier), ASTROGRID (Lawrence) and Jodrell Bank (Diamond) + NVO affiliates
• Asked for funds for a three year Phase-A study of an Astrophysical Virtual Observatory – 7.2 Million € (50% from EU and 50% from organizations)
• Focus on – Multi-wavelength science case demonstrations (ASTROVIRTEL
basis)– Interoperability demonstrations (CDS/All)– Technology assessments and testbeds (ASTROGRID/ESO)
P.Quinn TIVO June10-14 200212
AVO STATUS•AVO approved with EU funds ~2 Million € (total budget ~ 4M €)• Contract start on 15 November 2001 - 3 Year Phase A study• 9 NEW POSITIONS for 3 years over 6 institutions - total 18 FTE (~ 50 people)•Total VO funding AVO+NVO+ASTROGRID = $21 million (US)•3 Year target :
•Build VO 1.0 among the 6 partner archive sets by•Defining and executing trial science cases•Defining, developing and deploying new interoperability standards and tools•Developing and deploying new Grid-based services

VO ChallengesAVO: 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 200218
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 200219
The International Virtual Observatory Alliance
P.Quinn TIVO June10-14 200220
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

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 200226
ESO Archive Policyhttp://archive.eso.org/Archive_Access_Policy.htmlESO 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.
