AB:
After almost three years experience in developing the Virtual
Solar-Terrestrial Observatory (VSTO), we report on what we have learned
about the level of knowledge representation required to
satifying the science user needs. To date, we have achieved
a unified query workflow based on an abstraction of classes
(instrument, parameter, date-time) and provided semantic web services
to make these available across the internet. We have also moved to
the next level and generation of classes that capture science-level
(higher) concepts such as state of the atmosphere, domains (e.g. neutral
upper atmosphere), spatial locations, and parameterized representations of
time (e.g. high geomagnetic activity). We also outline our plans for
further representation, logic and reasoning within VSTO.
VSTO is an NSF/OCI-funded joint effort between the High Altitude Observatory
and the Computing and Information System Lab at the National Center for
Atmospheric Research (NCAR) and McGuinness Associates Consulting.
