EXQuery

A hopeless technologist with a bent for Software Engineering travelling an XML adventure.

With a strong background in Software Engineering, preferably Java and XML, Adam has been involved in XML systems for a number of years now. Previously developing entire web applications in XML and XQuery, he is now focused on the problems of applying traditional data-warehousing approaches to XML. Adam has also been a developer on the eXist XML Native Database open source project since early 2005, contributing mainly in the field of XQuery functionality and APIs. Otherwise he likes to Snowboard!

"After adding a number of proprietary XQuery functions to eXist to enable XQuery application development and knowing that various other XQuery implementations had their own approach to these or similiar functions, I realised that what the EXSLT effort had done for XSLT 1.0 was required for XQuery. That was around the time of the XMLPrague 2007 conference. Time is something that I never have enough of, but recent discussions with Dan McCreary and an article on Kurt Cagle's blog about similar issues refocused me and hence the birth of EXQuery. However, there is more to XQuery application development than just functions and I hope EXQuery can also tackle and standardise other aspects of XQuery Applications."

Matthias is a software architect at 28msec Inc. The mission of 28msec is to enable everybody to easily develop, test, deploy, and host web applications written in XQuery. The product being developed is called Sausalito which is an integrated XQuery application server, web server, and database system for the cloud. It is important that applications written with XQuery in Sausalito are portable among many of the existing XQuery engines. Matthias is also a core developer of the Zorba XQuery processor which is developed by the FLWOR Foundation. Before joining 28msec, he has been working on optimization techniques for declarative query languages.

John Snelson is a Software Engineer from Oxford, UK, and works for Oracle on the Berkeley DB XML and XQilla projects. He is a member of the W3C XQuery working group.

Wolfgang founded the eXist XML Native Database project back in 2001 and still dedicates most of his time to it. Since many years, eXist has been promoting the development of web applications entirely written in XQuery. Standardizing some of the required function libraries will be a another step towards a broader adoption of XQuery-based web development.

Florent is an XML architect working in Brussels. He has been involved for many years in the XML community, especially the XSLT (and later XQuery) communities. He is involved in the new version of EXSLT. Trying to improve XPath-based languages as XSLT and XQuery is one of its current goals.
