| 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 control and version control functions and their various extended models separately. Because of a strong correlation between both functions, the most important issue, the efficient management 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 automatically assign predefined instance level policy documents with a new version of protected documents by analyzing changed content. Moreover, by extending the framework with 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 computation sub-layers. The framework is employed by a unified modeling language, namely XML Declarative Description (XDD). XDD not only directly employs HL7 CDA and XACML standard as a protected document and access control policy representation, but also enables 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. |
