• Since authorization rules (authorizations, for short) use path expressions of XPath for locating data in documents, authorization definition is related to the document format. However, the format of XML documents tends to change by various reasons such as application extension and information exchange between organizations. Therefore, authorizations must be revised whenever they become incompatible with a new format of the document. We define sufficient conditions for schema and document transformations that allow transforming authorizations without access to individual source and target XML documents. We propose an algorithm that computes authorizations for a target DTD instance from given RBAC authorizations of a source DTD instance and schema mapping information under certain schema and document transformations while preserving the authorization requirement of the source DTD instance
