Summary
The National Virtual Observatory (NVO) will directly or indirectly touch upon all steps in the process of transforming raw observational data into "meaningful" results. These steps include: (1) Acquisition and storage of raw data. (2) Data reduction (i.e. translating raw data into source detections). (3) Aquisition and storage of detected sources. (4) Multi-sensor/multi-temporal data mining of the products of steps (1), (2) and (3). (Not complete.)
