8. 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 projects. –Implementation of IVOA standards and infrastructures developed by other VO projects. 39 participants from Korea, Japan, India, Europe, UK and China (including Taiwan)

13. 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

14. 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

15. 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

16. 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

19. 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

20. 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) 30  40m fully steerable gigantic parabolic dishes, about 80 km north of Pune

21. Some examples GAVO –federation of archives available in the German astronomical community –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 resources

22. Large sky Area Multi-Object fibre Spectroscopy Telescope Clear aperture:  4m Field of view:  5° Focal plane:  1.75m Focal length:20m Number of fibers:4000 Spectral ranges:370 ～ 900nm Spectral resolution:1 ～ 0.25nm Sky coverage:Declination -10  to+90  A meridian reflecting Schmidt telescope VO-enabled LAMOST

23. VO-enabled –LAMOST data –LAMOST telescope –LAMOST Spectral Analysis Pipeline

24. Beijing-Arizona-Taiwan-Connecticut Sky Survey Started in 1995 data archived on CD- ROM and hard disks comprise about 600 GB. 0.6/0.9 m Schmidt telescope 15 intermediate-band filters

25. Improve current HTTP, FTP interface Provide VO- compliant interface BATC Data Release Platform Current Interface
