CR 13907:2000

This Technical Report describes a general model of the conceptual stages involved in the interchange of data composed of graphic characters between two end users. It identifies those aspects of this communication process that are amenable to further standardization and it provides terminology that permits such standards to specifiy their roles within this model. It is not intended as a guide to the implementation of such standards as in many cases the conceptual stages do not correspond to the practical stages involved in an efficient implementation.
