In today's office data processing environment, two architectures have evolved, one of which governs how information is communicated from office equipment to a host computer and another between host computers to allow "document" interchange between host systems. A standard Generalized Data Stream (GDS) encoding scheme is used to form information into a data stream. Each atomic piece of information in a GDS is self-defined in a basic information unit known as the Document Interchange Unit (DIU), which starts off with the length of the piece of information (LL) followed by an identification (ID), the attribute or format (F) and then the information itself (data), or in some systems the DIU is an LT type (length, type, data).
