XDGL: XPath-Based Concurrency Control Protocol for XML Data.
Today XML has become the most important data exchange technique on the World Wide Web. As a consequence the interest in concurrent XML processing has greatly increased.
In this paper we propose a new XPath-based DataGuide Locking protocol (XDGL), which generalizes on and extends the hierarchical data locking protocol. This new protocol takes into account the semantics and nature of XML. It can be easily implemented on top of traditional databases as well as in a native XML DBMS.
