| Abstract: |
The International Virtual Observatory Alliance (IVOA) developed numerous
interoperability standards during the last several years. Most of them are
quite simple to implement from the technical point of view and even contain
“SIMPLE” in the title. Does it mean that it is also simple to build a
working VO resource using those standards? Yes and no. “Yes” because the
standards are indeed simple, and “no” because usually one needs to implement
a lot more than it was thought in the beginning of the project so the time
management of the team becomes difficult. In our presentation we will start
with a basic case of a simple spectral data collection. Then we will
describe several examples of “small” technologically advanced VO resources
built in CDS and VO-Paris and will show that many standards are hidden from
managers' eyes at the initial stage of the project development. The projects
will be: (1) the GalMer database providing access to the results of
numerical simulations of galaxy interactions; (2) the full spectrum fitting
service that allows one to extract internal kinematics and stellar
populations from spectra of galaxies available in the VO. We conclude that:
(a) with the existing set of IVOA standards one can already build very
advanced VO-enabled archives and tools useful for scientists; (b) managers
have to be very careful when estimating the project development timelines
for VO-enabled resources. |
