OK, great...

Myself being off-site, having a hard time even getting
hold off a internet-connected machine.

Anyways, to get down to buisness I will hand you some
off my thoughts:

I think we should separate the (default) GUI build
from the application System build. I have sketched
this out as Presentation Layer and System layer.

Presentation Layer is simple a GUI and it should most
probably always reside on the users client machine (ie
the desktop machine).
The default one (which we include in a distribution)
we build on SWING as JavaBeans, as of the Java 1.4 SE
branch. No need to involve any other frameworks there
than what users already have in the their default
installed JRE, plus that visual JavaBeans can also be
visually customized by the user in something called
BeansBox - without coding.

System layer consists of 2 sublayers: Buisness Layer
and Data Layer. These 2 should be able to put on any
machines from the client itself to any distributing
java-enabled server.

The Buisness layer is where the application do all
processing, managing and handling of data according
too their datatypes (more on that in a more detailed
spec later).

The Data Layer consists of the raw data: HTML, XML,
javascript, cionfiguration and any other files used or
handled by the application.

For the Buisness Layer we need to decide on wheter we
want Apache Avalon (the stronger candidate - see
http://jakarta.apache.org/avalon/index.html ) or use
the Bebop framework (another SourceForge project -
fairly newly begun; you'll recive the sources to
review soon).

For parsing of HTML/XML (our default DOM parser) we
could consider making the Apache Jakarta ECS (Element
Construction Set - see
http://jakarta.apache.org/ecs/index.html ).

As previous planned we'll use Mozilla.org's Rhino for
Javascript parsing (and possibly rendering too) -
unless anyone object of course ;)

With those and other Open Source projects applications
and utilities put into components, I think we can pull
this off without too much of a chore. 

As always: If you have any ideas, comments or
objections - don't hesitate to share them...

Henrik
