W3C releases a raft of new XQuery and XPath documents.

The World Wide Web Consortium (W3C) has updated draft specs for XML Path Language (XPath) 2.0, XML Query Use Cases, XQuery 1.0, An XML Query Language, XQuery 1.0 and XPath 2.0 Formal Semantics, XQuery 1.0 and XPath 2.0 Data Model and XQuery 1.0 and XPath 2.0 Functions and Operators.

As that list indicates, the main changes are the result of a further integration of the XQuery and XPath specs. Several of these working drafts represent collaborative work by the XSL and XML Query Working Groups, which are jointly responsible for XPath 2.0, which is a language derived from both XPath 1.0 and XQuery. The XPath 2.0 and XQuery 1.0 Working Drafts are generated from a common source.

While XPath does not (yet?) play a major role in e-learning standards, XQuery does: it is the main mechanism with which the recently released IMS Digital Repository spec envisages that people will retrieve learning objects from IMS compliant repositories. In other words: updates to W3C's XQuery in effect become part of IMS Digital Repository.

The draft specs are available from the W3C XQuery page.
