| Abstract: |
The Common Archive Observation Model (CAOM) is used as the core data model for
all data holdings at the Canadian Astronomy Data Centre (CADC): 12 million
data
products spanning 20 collections and including images, spectra, cubes, time
series, and catalogues. The CADC supports both in-house and external data
engineering efforts by providing client tools and operating a CAOM observation
repository service where data engineers have permission to create, update, and
delete observation metadata.
CAOM supports anonymous access for public data and authenticated access to
proprietary metadata and data. The content is loosely coupled to data storage
and delivery system. In addition to the CADC AdvancedSearch (web portal), CAOM
also supports International Virtual Observatory Alliance (IVOA) services and
data models to provide an end-to-end solution for data discovery and data
access. CAOM is an open source model and open source codebase that is evolving
along with the demands of both data variety and the needs of science users,
science teams, and data centre operations. |
