ABSTRACT
This chapter offers a brief review of the more popular ways of data structuring and highlights some of the problems that each of them is meant to handle. The mixed arrangement is notorious in digital representations, which are typically based on hierarchical data models of HTML or extensible Markup Language (XML), and use links, in order to cope with the constraints imposed by the tree structure. The chapter focuses on the most relevant issues of data modeling for researchers in the humanities and reviews the basic kinds of the relevant data models. It focuses on approaches that use XML, but the models can also be applied more generally. The structure of the larger units is dictated by the internal syntactic rules of the given language but it is also modeled technologically by the selection of the given XML document grammar. Packaging of complex information raises new theoretical questions and demands new, more efficient, technological solutions.
