1 The NVO Portal Tom McGlynn, NASA/GSFC Gretchen Greene, ST ScI John Good, IRSA/IPAC Roy Williams, CACR/Caltech Mike Fitzpatrick, NOAO T HE US N ATIONAL V IRTUAL O BSERVATORY

2 Purpose Make it easy for astronomers to find useful information in the VO Accommodate many different kinds of searches Web interface with no required downloads Easy linkage between Web and scripting capabilities No VO jargon 20 May 2008McGlynn: IVOA Meeting-Trieste2

3 Design Collaborating, distributed, simple elements Standard protocol for transmitting information between elements: List of sources List of resources –All VOTables Elements call each other as appropriate with many starting points. Common templates and vocabulary 20 May 2008McGlynn: IVOA Meeting-Trieste3

28 Key elements Common template -> coherent environment Common JavaScript/XSLT VOTable processing –Potentially useful in any Web app that displays VOTables. Standard formats for passing information among elements. VOClient used within inventory, table viewer as well as by users. 20 May 2008McGlynn: IVOA Meeting-Trieste28

29 Status and Plans All elements functional Alpha release for comment and testing –http://heasarc.gsfc.nasa.gov/vo/portal and links thereinhttp://heasarc.gsfc.nasa.gov/vo/portal Registry inconsistencies can lead to services not being found. Further work in eliminating jargon and smoothing user experience. Beta release to public soon. Please send comments! 20 May 2008McGlynn: IVOA Meeting-Trieste29
