Abstract

As Document Content Architecture advances, it becomes necessary to operate on complex combinations of text, image, graphics and other types of information in multiple data stream environments. To achieve this, the data stream functions are divided into two distinct layers with independent but coordinated architecture in each layer, resulting in the use of common object definitions across the different data stream environments. A process for generating a data stream which contains mixtures of text, image, graphic and other types of information in such a way as to minimize the processing required in moving data from one data stream environment to another is constructed and operates as follows.

Mixed Data Types in Multiple Data Stream Environments

      As Document Content Architecture advances, it becomes
necessary to operate on complex combinations of text, image, graphics
and other types of information in multiple data stream environments.
To achieve this, the data stream functions are divided into two
distinct layers with independent but coordinated architecture in each
layer, resulting in the use of common object definitions across the
different data stream environments.  A process for generating a data
stream which contains mixtures of text, image, graphic and other
types of information in such a way as to minimize the processing
required in moving data from one data stream environment to another
is constructed and operates as follows.

      To meet the above specified requirements, the data stream
architecture subdivides the data stream function into two
functionally independent layers, a data stream or environment layer
and an object or information layer.  Given this structure, objects
can be created, edited and stored independently, or combined to
create compound information units.  In addition, they may be
transported and mixed in any of the different data streams or moved
from one data stream environment to another with a minimum of
processing.

      Referring now to the drawing, an information handling system
includes a processor 15 with a data stream architecture divided into
an interchange environment between a processor and terminal devices.
Data in the interchange format enters the system through a
