Proceedings of the 1989 ACM SIGMOD international conference on Management of …, 1989•dl.acm.orgA simple model for representing the hierarchical structure of information is proposed. This
model, called the grammatical model, is based on trees that are generated by grammars; the
grammars describe the hierarchy of the information represented by the trees. Two
transformation languages, an algebra and a calculus, are presented and shown to be
equally expressive.
