AB: The Joint Science Operations Center (JSOC) is designed to provide data capture, archive, analysis, and distribution functions for both the Helioseismic and Magnetic Imager and the Atmospheric Imaging Array on the Solar Dynamics Observatory. These instruments are notable for the large quantity of raw data they will generate, more than doubling the total volume of all existing solar data in the first few months alone. In addition, the JSOC will be required to handle a larger component of higher-level data products than most previous missions. The fundamental concept of the JSOC architecture is that the metadata and bulk image data are stored separately, not being combined until the time of use or export. This enables all metadata to be rapidly accessible through a relational database. It permits flexible organization of the data into virtual data sets or series, and the use of an abstracted syntax, such as a URL, for data description and querying. Furthermore, data organization details dictated by the requirements of efficient mass storage can be hidden from the user. Multiple classes of access to the processing and data are envisioned, ranging from production pipeline modules generating standard mission products to workstation users analyzing self-contained data products exported from the archive. The JSOC design provides a rich set of primitives upon which VSO-like services can be built, and should allow us to provide a unified view of the data and data services to all classes of users.
