| Abstract: |
While VO services such as SIAP and SSAP allow astronomers to issue the
same query to different data repositories programmatically, making a
definitive seach of the world's archives is problematic for several
reasons. Not all archives provide these VO services and of those that do,
not all comply to the VO standards. While packages like Astroquery
make it easier for astronomers to build a tool to query different
archives, regardless of the presence or absence of a VO service, not
all astronomers have the inclination to do so. Finally, if any of the
many services being queried is unresponsive, the query will be incomplete.
Therefore the CADC has embarked on a program of retrieving
metadata from as many of the world's archives as possible and
ingesting that metadata into the Common Archive Observation Model
(CAOM). The queries can then be issued with the existing CADC search
system that will return a list of observations, together with links to
the data itself, not only of the CADC archive holdings but also those
of other archives worldwide. |
