About XQueryXQuery is a query language for XML. It is developed within the W3C by the XML Query Working Group, as part of the XML Activity. XQuery is a simple but powerful language that supports a large variety of data-oriented and document-oriented XML applications. From 1000 feet, the salient features of XQuery are:
High-level requirements for XQuery can be found in the XML Query Requirements Documents. Many applications and XQuery examples can be found in the XML Query Use Cases. More information on XQuery, and the W3C XML Query Working Group, can be found on the W3C XML Query homepage. About GalaxWhat is Galax?Galax is an open-source XQuery implementation. Our goal is for Galax to be a fully compliant implementation of the family of XQuery working drafts. Currently, Galax implements most of the following specifications from the XML Query Working Group:
The XML Syntax of XQuery XQueryX is not supported. Who should use Galax?Galax is a portable and extensible implementation of XQuery, with a liberal open-source license which makes it ideal for:

The Galax Team, past and present.
We have always a long list of things TO DO. So if you want to help, don't be shy and drop us a note! Thanks!To Rob Dinoff who helped with the development infrastructure (notably the CVS and Web servers). To Volker Renneberg who helped implementing the XML Query Algebra prototype that preceded Galax. To the members of the XML Query Working Group, notably Peter Fankhauser, who contributed ideas and suggestions. To the XDuce team, notably Haruo Hosoya, for discussions and for allowing us to use their subtyping algorithm at the early stages of our implementation. To the Caml team for developing the best programming language in the world. To the XML-QL team, Mary Fernández, Dan Suciu and Alin Deutsch for providing some help with the CGI scripts originally used for the on-line demo. To Arnaud Sahuguet for the Galax logo. |
