Abstract: The AXAF Science Center (ASC) is defining a standard scientific Data Model for use in its data analysis system. This Data Model is an abstract description of underlying data structures, with components such as lists, arrays, header values, and filters. The design of the implementation includes the use of the Dynamic Data Format (DDF) which provides a uniform API (i.e., the Data Model) to the developer, yet allows the user the flexibility of multiple disk formats. Corresponding to each disk format is an API and its own model of the data. The ASC Data Model requires additional functionality and more structure than any individual Off-The-Shelf (OTS) model provides. This paper describes both the components of the Data Model and the design of a flexible layering scheme for implementing the DDF.
