Subject: Re: Rivet namespace and Rivet package
just a comment to Massimo's question, sorry there is no dowload yet, as I am
still in a pre alpha state with ATWF.
ATM I am thinking about having "Reporting Tools With TCL" as the first "real"
application to run with ATWF and doing so I found I should have an interface
language like XUL or XAML or some other XML kind of thing for describing the
widgets and actions etc. for a GUI using CSS files for the look and feel and
a small css interpreter, to do the configure for a Tcl/TK GUI and perhaps to
have a similar functionality based on the same interface using javascript or
.... for supporting browsers on the other hand. I have also looked at xml2gui
and am still in the brain storming phase.
So right now my stack of work to be done is still increasing instead of
decreasing, but I hope to soon stop at least the increasing.

If I can suay you to *NOT* use xml, and instead, use a JSON like language.
It is *SO* easy to parse ... uses very few terminals, and like TCL, is
whitespace delimited.
I've attached a JSON like scripting example from which I generate SQL DDL
for a database independant schema tool ... such a schema can also be used
to generate forms with a rich data definition language ... and these can
be used to generate tcl/PHP/or whatever ... no XSLT, no XML-schema, no
complicated parsing ... but very expressive nonetheless ....
