In my humble opinion I think XML is great!
As a pre-'Master' student is am started playing with XML about a year ago and
a few
months ago i released DatabaseAccessDefinitionML (DADML) and found that XML has
many very interesting aspects that complement current internet standards. Like
siteChanges.xml.
DADML makes it possible to connect database over the internet. It consist of
three
components: one defines a superdatabase and links other real databases; a
second
defines a 'real' database with definitions of the fiels, how they are indexed,
how they can be retrieved (URL, free/commercial etc.) and more; the last
component
defines the indices for which information is available. This last file can be
generated
automatically through CGI scripting ofcourse.
This project is pure out of enthousiasm for XML and as small as it is shows how
easy it is AND how much fun it is to work with XML. Even if it is just a
hobby...
The first practical use of DADML is currently being developed. A preview can be
viewed at the Woordenboek Organische Chemie. Try the following link

The links bellow the Databases picture are the fields of the 'real' databases
written
boldly. The designation (misschien aanwezig) means 'note sure if information is
available for this compound'. That is because there is no data indexfile for
this
field given. Although a superdatabase can also check the availability by
questioning the http deamon. If File Not Found is returned this field is
obviously not available for this compound.

XMl really is a lot of fun!
