| Abstract | The Canadian Astronomy Data Centre has developed a general purpose scientific data model and an API for accessing a scientific data warehouse. The Catalog API defines a general mechanism for exploring and querying scientific content using a constraint-based design. The API provides access to separate but related catalogs and allows for entries in one catalog to be related to (usually derived from) entries in another catalog. The purpose of the API is to provide storage-neutral and content-neutral access methods for scientific data. The API defines a network-accessible Jini service.
We have developed the Canadian Virtual Observatory (CVO) as Jini services that implement the Catalog API. These catalogs store astronomical content: the pixel catalog provides uniform access to our many archival data holdings, the source catalog stores the results of image analysis, and the processing catalog stores metadata describing exactly how sources are extracted from pixel data. Entries in the source catalog are connected to entries in the processing and pixel catalogs from which they are derived. |
