An Access Control Method Based on the Prefix Labeling Scheme for XML Repositories

Yokoyama, S., Ohta, M., Katayama, K. and Ishikawa, H.

This paper describes an access control method of the XML repository system, SAXOPHONE, which was implemented at Tokyo Metropolitan University. The main feature of our research is a novel account identifier that is based on the prefix-labeling scheme to realize a hierarchical authorization. SAXOPHONE uses relational databases for XML document storage. Using it, any valid or well-formed XML document is decomposed into events of the SAX parser and is then stored into relational tables using a fixed scheme. Consequently, users can handle the system as a normal SAX parser. This study also illustrates how to realize an access control method of XML documents on relational databases using the account identifier.
