BABYLON Version 2.3
*****************************************************************************
What is BABYLON
*****************************************************************************
BABYLON is a modular, configurable, hybrid environment for developing
expert
systems. It provides the following knowledge representation formalisms:
frames,
rules,
logic (Prolog) and
constraints.
BABYLON is implemented and embedded in Common Lisp.
The archive contains all the sources that are needed to compile
and run BABYLON on different hard and software platforms (Mac, Sun, ...).
Version 2.3 is a maintenance release of 2.2 with some reworking to make it
more portable. To this end, the whole babylon implementation is put into
the
:babylon package. So put your knowledge bases into th :babylon package or
use
the :babylon package. Also included is some documentation (in the doc
directory) in RTF (Rich Text Format) and some more complex examples (see
axtra sample kb and the texi and model-k directories).

*****************************************************************************
Lisp implementations supported
*****************************************************************************
In principle, babylon should run on any Common Lisp implementation.
The current version 2.3 has actually been tested with
Macintosh Common Lisp 2.0.1 on Apple Macintosh and
Allegro Common Lisp 4.1 and 4.2,
CLisp (january 1994),
CMU (version 16e) and
AKCL 1.615 on SUN.
Support for Lispmachines has been stopped. I do not have one available
any more.

how to get babylon
*****************************************************************************
You can get babylon from http://www.gmd.de/ using one of the Mosaic
versions
for example or by anonymous ftp from ftp.gmd.de
- FTP the distribution from ftp.gmd.de:
ftp ftp.gmd.de
Name: anonymous
Password: <email-address>
cd GMD/ai-research/Software/Babylon
get Babylon-2.3.sit.hqx <- for macintosh users or
binary
get Babylon-2.3.tar.Z <- for unix users
quit
- untar the distribution file (unix):
zcat Babylon-2.3.tar.Z | tar -xvf -
- or unstuff Babylon-2.3.sit.hqx (Stuffit Expander) on your Macintosh.
This will create a directory "Babylon-2.3" with all the subdirectories.

how to install babylon
*****************************************************************************
On an Apple Macintosh:
*****************************************************************************
Start MCL (Macintosh Common Lisp) and load the make.cl file.
You will be asked:
Use development options for compiling files? (y or n)
Answer y if you want to record source files, documentation strings etc.
This will cost some space in the saved babylon image but makes developing
much
easier. Type n otherwise.
After some time a dialog will pop up. Select which versions of the diffent
processors you want to have included in the babylon image. Preselected are
all
the normal versions of the processors. Now push the Save as... button to
get
a File Selection Dialog. Choose a name and place for the babylon image and
click the Save button. You will need about 3MB for the complete babylon
image.
If you click the Abort button, you will find a Cinfigure Image ... menu
entry
in the Babylon menu. You may use this menu entry to continue making the
image
after doing some other customization of your lisp environment (comiple
and/or
load some files etc.).
After some time you will be asked:
Load graphic frame browser? (y or n)
Answer y if you want to have a graphic oriented browser of the babylon
frame
inheritance structures. Make sure your MCL examples folder does contain
the file scrolling-windows and the library the file scrollers, because both
are used by the implementation of the frame browser. Compile both files
if you have not done this already.
;Loading #P"IHD:Applications:MCL 2.0:examples:SCROLLING-WINDOWS.fasl"...
;Loading #P"IHD:Applications:MCL 2.0:library:SCROLLERS.fasl"...
After compiling and loading all you wanted you will be asked:
Is your AntiVirus software temporarily disabled? (y or n)
Answer y after temporary switching off Gatekeeper in the Gatekeepe Controls
for example or allow MCL to write the resource fork of other files.
Do whatever you have to, to disallow your virus preventing software to
intervene.
Answer y now.
After some time the babylon image (application) will appear on disk and MCL
will quit. You can start babylon now by double clicking the babylon image.
On any other systems:
*****************************************************************************
Edit the make.cl file and change the following:
(defvar *babylon-root-directory*
#-:MCL "/home/juergen/Babylon/Babylon-2.3/" ; <--- change the pathname
string here!!!!
#+:MCL (namestring
(make-pathname :directory (pathname-directory
*loading-file-source-file*))))
and edit the make-sun.cl file and change the following:
(defbabylon-translation "babhome^" ">home>juergen>Babylon>Babylon-2.3>") ;
<--- change!!!
(Note: use ">" as the pathname seperators here!!!)
After having edited both files to set the babylon home directory you should
compile
and make a babylon image.
If you have one of the Lisp implementations mentioned above, do the
following:
1: change to the Babylon-2.3 directory
> cd Babylon-2.3
2. start your lisp
> clisp
3. load the make.cl file
> (load "make.cl")
4: go into the "BABYLON" package
> (in-package "BABYLON")
5. make the babylon image
> (make-babylon-image)
6. quit (or exit or cntl-d) your Lisp
> (quit)
Lisp image name start by typing (for exsample)
-----------------------------------------------------------------------
MCL Babylon doupleclick Babylon
Allegro babylon babylon
CLisp babylon.mem clisp -M babylon.mem
CMU babylon.core cmu -core babylon.core
AKCL babylon.kcl babylon.kcl
-----------------------------------------------------------------------
Copy a (modified to your needs) version of the bab-init.cl (and a copy of
extra.kb if you want to try out the extra sample) into your home directory.
The bab-init.cl file will be loaded after starting the babylon image.
*****************************************************************************
known problems
*****************************************************************************
CLisp (january 1994) does have problems with the optional line feed format
option "~&". Add a force-output or wait for the next release of CLisp.
If your Lisp implementation does not provide 'declaim' and 'defpackage' try
to use those within the clII directory.
