A Correspondence between UML Diagrams and SGML/XML DTDs

Abstract

In this paper, we compare the semantics and structure of the conceptual information presented in the Unified Modeling Language (UML), which is used in analyzing object-oriented systems, and Document Type Definitions (DTD), which define the structures of SGML and XML documents. SGML (Standard Generalized Markup Language) and XML (Extensible Markup Language) are international standards for specifying the notations used for defining structured documents. We present correspondence rules for generating DTDs semiautomatically from UML diagrams. The rules have been developed as a part of the analysis and design method to create the structure definition for a document. As an example, we use a patient record.
