From XML to RDF: Syntax, Semantics, Security, and Integrity

This paper evaluates security methods for eXtensible Markup Language (XML) and the Resource Description Framework (RDF). This paper argues that existing models are insufficient to provide high assurance security for future Web-based applications. This paper begins with a brief overview of XML access control models, where the protection objects are identified by the XML syntax. This paper shows that these approaches are limited to handle updates and structural modifications of the XML documents, thus security methods must be defined on the intended meaning of XML.
