A model and toolset for the uniform tagging ofhfill reak encoded documents

In this paper we present a new, abstract model for textual data objects with embedded markup. Based on the model, we propose a uniform representation for these objects that borrows its concrete syntax from the ISO standard SGML. Such a uniform representation will greatly facilitate the development of software that analyzes, formats or otherwise processes these objects. We then describe a toolset that supports the retagging of existing encoded data objects to the new uniform representation. Our experience with the toolset demonstrates a savings of approximately 10:1 over a retagging effort without the toolset.
