Abstract
XQuery 1.0 and its sister language XPath 2.0 have set a fire underneath database vendors and researchers alike. More than thirty commercial and research XQuery implementations are listed on the XML Query working group home page (http://www.w3.org/XML/Query). Most of these implementations are targeted to particular storage systems or application domains.
Galax (http://www.galaxquery.org) is an open-source, general-purpose XQuery engine, designed for maximal extensibility. In this talk, we will discuss Galax’s extensibility features and the design trade-offs that we continuously face between extensibility and performance.
