dc.description.abstract As more and more documents are made available in the eXtensible Markup Language (XML) format, concerns are being raised about XML document management problems. Existing research has investigated access cont rol and version contro l functions and their various extended models separately. Because of a strong correlation between both functions, the most important issue, the efficient manageme nt of interrelation, remains open. This thesis introduces a unified framework integrating version and access control techniques in an efficient way to realize advanced management of XML documents. The main contribution of this research is to present a method to automati cally assign predefined instance level policy documents with a new ve rsion of protected documents by analyzing changed content. Moreover, by extending the framework w ith temporal features, the utilization of the temporal data can be supported. For example, the framework has the ability to retrieve the documents, which are valid at a certain time. Furthermore, the unified framework is also designed to realize document management system interchangeability, interoperability and integrability by subdividing a foundation layer into unified representation and comput ation sub-layers. The framework is employed by a unified modeling language, namely XML Declarative Descrip tion (XDD). XDD not only directly employs HL7 CDA and XACML standard as a protected document and access control policy representation, but also en ables direct computation of all functions and flexibility of knowledge modification, which characterizes the framework. The separation of foundation introduces more flexible system architecture, so that different vendors can use their own computational models.
