The World Wide Web Consortium (W3C) XML Query Working Group [1] was
chartered in September 1999 to develop a query language for XML [2]
documents. The goal of the XML Query Working Group is to produce a
formal data model for XML documents with Namespaces [3] based on the XML
Infoset [4] 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 [8] in January 2000.
Subsequently it has published an XML Query Data Model Working Draft [9],
an XML Query Algebra Working Draft [10] and a syntax for the XQuery
language [11].
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 [12] and to the work of the W3C Internalization WG.
