06472 Executive Summary -- XQuery Implementation Paradigms

Only a couple of weeks after the participants of seminar No. 06472 met in Dagstuhl, the W3C published the Final Recommendation documents that fix the XQuery 1.0 syntax, data model, formal semantics, built-in function library and the interaction with the XML Schema Recommendations (see W3C's XQuery web site at http://www.w3.org/XML/Query/). With the language's standardization nearing its end and now finally in place, the many efforts to construct correct, complete, and efficient implementations of XQuery finally got rid of the hindering "moving target'' syndrome. This Dagstuhl seminar on the different XQuery implementation paradigms that have emerged in the recent past, thus was as timely as it could have possibly been.
