Querying XML Documents
Paul Cotton - Microsoft Canada & Jonathan Robie - Software AG
The World Wide Web Consortium (W3C) XML Query Working Group  was chartered in September 1999 to develop a query language for XML  documents. The goal of the XML Query Working Group is to produce a formal data model for XML documents with Namespaces  based on the XML Infoset  and XML Schemas [5-7], an algebra of query operators on that data model, and then a query language with a concrete canonical syntax based on the proposed operators.
The WG produced its first Requirements document  in January 2000. Subsequently it has published an XML Query Data Model Working Draft , an XML Query Algebra Working Draft  and a syntax for the XQuery language .
This talk will provide an update on the current status of the W3C XML Query WG. The talk will also outline the relationship of the work of the XML Query WG to other W3C XML standards especially XML Schema and XPath  and to the work of the W3C Internalization WG. The talk will include demonstrations of two different XML Query prototypes.
