Small project meeting, Beijing
• 26-28 November 2003: Beijing, China• Main topics:
– Advantages and disadvantages of small projects. – The role of small projects in the IVOA. – R&D focus of small projects. – Collaboration among small projects and with big VO proje
cts. – Implementation of IVOA standards and infrastructures de
veloped by other VO projects.• 39 participants from Korea, Japan, India, Europe,
UK and China (including Taiwan)

Bridging IVO Standards ~ Best Practice
Best Practices• As resources, tools• It is important for the IVOA standards
and recommendations to be learned and adopted by astronomers/users.
• As references and guides• It is important for VO developers and
data providers
Small project is suitable for the role
• Familiar to IVOA standards
• With required IT/CS backgrounds (Grid, WS, XML, SOAP, etc.)
• Know well astronomer requirements
Some examples
• Aus-VO– Skycat
• astronomical catalogue server, provides access to BGC, HIPASS, HIPASS HVC, SUMSS catalogs
– Volume • VOTable data visualization tool using VRML
• VO-India– conVOT
• a tool for converting ASCII or FITS tables to VOTable format – VOPlot
• the “most popular” VOTable visualization toolkit• HVO
– Filter Profile Service and Spectrum Service, cooperated with Johns Hopkins University
VOTFilter from China-VO
• An XML Filter written in XSLT • for OpenOffice Calc• to read&write files in• VOTable format
• Easy of use, no Java, XML, VOTable knowledge is required.
• Link IVOA standard with industrial desktop application

b. Bridging IVOA and the Domestic Community
Bridging IVOA ~ Domestic Community
Common tasks for small projects• to contribute domestic data archives
and expertise to the world• to share international data, tools with
international partners for domestic research and education
• a “gateway” between domestic and world wide resources
Some examples
• Aus-VO– HIPASS: HI Parkes All Sky Survey– ATCA Archive:Australia Telescope Compact Array – MACHO Archive: Massive Compact Halo Objects
• VO-India–Ladakh telescope
•2 m remotely operated Himalayan Chandra Telescope (HCT)
–Giant Metrewave Radio Telescope (GMRT)
•3040m fully steerable gigantic parabolic dishes, about 80 km north of Pune
Some examples
• GAVO– federation of archives available in the German astronomical co
mmunity– creation of a theory-oriented component to the VO– development of advanced datamining algorithms
• RVO– To unite Russian and fSU data, to integrate them into the IVO– To provide Russian astronomical community with a convenient
access to the world data– To use Russian instrumentation to provide observational data in
remote mode when needed– To develop Russian electronic astronomical education resource
