==== Description: ====
My project indends to address a case when data stored in a set of XML files
shares some part of information in a structure similar to an object class
hierarchy. Elements of such a hierarchy share a fair portion of data and
modification of properties contained in many files requires changes in many
file. This is in contrary to DRY paradigm and it is error prone.

The tool introduces a set of XML elements and attributes located in a
separate namespace that allow organizing the XML data in a way similar to
implementing a hierarchy of classes (the mechanism is a bit simplified as
there are no methods). A tool processes these files and produces final XML
output.

A "base class" is defined as a set of XML nodes (not necessarily one XML
element) that contains "extension points" which can be overwritten by
subclasses. Subclasses may overwrite a chosen subset of extension points. They
may also define new ones. The tool supports nested classes, also there may
exist many extension points with the same name, which helps address some
cross-cutting concerns. Standard inclusion will also be provided, too (maybe
XInclude may be used, the functionality is not yet implemented).

The application is now in pre-alpha stage (it processes correctly written XML
files with some advanced functionality disabled). The specification is in
paper version only at the moment - it covers some more functionality not
provided here. 

A snapshot of the source code may be found here:
http://marchant.republika.pl/data/xover_20071018.zip 

You may see some examples in doc/samples/xhtml-sample directory (they are not
very good examples of the software usability, however), and a test sample can
be found in xo/sample directory - input.xo.xml is transformed to input.xml.




==== Other Software Required: ====
The project uses Java. The project has not yet been tested with GCJ. I am
going to do it soon. However, only standard Java classes are used that have
been in JDK since 1.4 at least (or if newer classes are used they can be
easily replaced with older counterparts).

All XML manipulations are performed using JDOM (http://www.jdom.org).
