XML for End Users
We are developing an XML query and transformation language that is
particularly targeted at end users who have no formal training in databases
or programming. The language is based on a document metaphor and allows
simple selections in the style of "query-by-forms" as well as more
sophisticated transformations that are expressed by so-called
document rules. We are currently developing a graphical user
interface to aid the construction of queries.
We also investigate the automatic generation of XML transformations
to help users to integrate different XML data sources.

Here is a prototype implementation to download and play with.
Gunzip and unpack the archive
Start the query interface by entering the command
run (or run.bat on Windows).
Click on the XML Data button on the left panel to pick the XML
data source URL.
- In the popup window, enter the URL of the data source you want to query.
You can use any XML file you like. One example file is located at http://www.cs.orst.edu/~abraharo/bib.xml.
Click the OK button.
In the folder panel that pops up, click on the name field at the
top and enter: bib
This should be the name of the ourtermost XML element in
the XML data source.
Click on the folder panel to select it (a red boundary appears
around objects that are selected).
Click on the Card button on the panel on the left to add a card to the
Click on the card-name area on the card and enter: book
This is to specify that you are looking for information on the book
elements in the database.
Click on the Run Query button on the FoXQ interface and the
Result-Viewer interface comes up with all the information on all the
books stored in the bibliography database.
For more information, see the README and INSTALL files that are included
in the distribution.
