OrdPathX: Supporting two dimensions of node insertion in XML data

Abstract

We introduce a novel XML labeling scheme called OrdPathX which supports both leaf and internal node insertions for XML data. Dynamic XML labeling has been studied for years. However almost all labeling schemes allow only leaf node insertions. Inspired by the careting-in technique of OrdPath [7], we propose a new labeling algorithm which supports internal node insertions gracefully without relabeling. We will describe the labeling algorithm and the associated operations for various inter-node relationship determination. Experimental results show that OrdPathX can handle internal node insertions efficiently. © 2009 Springer Berlin Heidelberg.
