METHOD OF DATA STREAM CONSTRUCT MANAGEMENT UTILIZING FORMAT SHELLS AND SHELL FRAGMENTS

A method is disclosed for dynamically redefining a shell structure which includes embedded formatting, processing or resource information. The shell structure includes end user requirements necessary to process constructs within a data stream which are accessed by means of embedded tags within the data stream. Data stream clutter is reduced and end user formatting is rendered more flexible by embedding tags in the data stream to a point in one or more shells accessible by the end user's work station; however, it is often desirable to modify a particular shell for a specific application without permanently altering the shell. A formatting shell fragment is created in accordance with the present invention which includes a reference to a complete shell and a temporary modification to be applied to that shell. In a preferred embodiment of the present invention multiple formatting shell fragments may be concatenated with other formatting shell fragments and a complete shell. In this manner, a data stream may be processed by utilizing an existing shell structure which has been temporarily redefined for that purpose.
