A Progress Report on XQuery

Don Chamberlin

Abstract: This talk is a progress report on XQuery, a language proposal being developed in the W3C XML Query Working Group. It will describe the current state of the XQuery language, its data model, its type system, and its relationship to other W3C standards such as XPath and XML Schema. We will examine the reasons for some aspects of the XQuery design and discuss some issues that are still under consideration by the working group.

Speaker: Don Chamberlin represents IBM on the XML Query Working Group, and was a co-author of the Quilt language proposal that served as the basis for the XQuery design. Don is best known as co-designer (with Ray Boyce) of the SQL database language and as author of two books on IBM's database products. He received a Ph.D. from Stanford University in 1971, was named an ACM Fellow in 1994, and was elected to the National Academy of Engineering in 1997.
