Abstract

A family of practical queries, which aim to return or manipulate paths as first class objects, cannot be expressed by XPath or XQuery FLWOR expressions. In this paper, we propose a seamless extension to XQuery FLWOR to elegantly express path-centric queries. We further investigate the expression and processing of intra-path aggregation, an analytical operation in path-centric queries.
