Hi,

I don't know if you remember me, but I made an announcement a few months
ago about the developpment of a set of business software in Erlang.

I worked on specification and I am now at the point of starting the
development.

I am working on a little tool on top of mnesia, to manage objects as a
hierarchy. I use a table matching a path to a table, and I made it
possible to work on a complete branch of the tree and to manipulate a
set of objects.

Does such tools already exist in Erlang ?

I find that the way I am doing this is very ugly. I need some kind of
Erlang mentor to help me to get acquainted with good Erlang programming
methods and habits and to show me the Erlang wy to do things.
I there someone here that would play this part.

I fact I also need to know how you would strucutre the modules, the
directories, and so on.
I am not completly sure that this library is useful and is well coded.

If a good soul is willing to help me, maybe I can place the code on a
web server to let you access it.

Thanks in advance for your help.

Ok, I've just posted a few weeks ago a question about linking erlang with
legacy systems using ODBC or similar. My goal is a bussines suite in Erlang,
probably with an interface in other language more suitable (Java?).
I'm very interested in a project wich name can be Wink Open-ERP ...

I know it is a very big work, but it must be started in some point someday

Fantastic, I have no too much time, but I'm VERY interested.

I don't have played too much with Erlang, but in a bussines environment we
must deal with legacy databases (Oracle, Informix,...)

I don't know

The same for me.

I know a place where we can test it in a real production environment.

It's nothing.

I suggest that you simply post the code here (or a pointer to
the code) The worst that can happen to you is that nobody
had anything to say about the code. In that case it's either
perfect or beyond commentary/remdey. So post asway ..

As for erlang modules I suggest a simple scheme that is similar
to the structure erlang itself. A least if the application
is of any size.

Makefile.in
configure.in
doc
lib
Makefile
lib1
src
Makefile
foo.erl
ebin
foo.beam
c_src
Makefile.in


lib2 ....

Then make your start script setup the erlang code paths correctly.

I am interested in further discussions along these lines. *Please*
send me private email if you'd like to be a part of some discussions
in order to keep the traffic down on this mail list. I am building
some applications in Erlang, inets, mnesia, etc. with the intent to
evolve the applications into a "framework" for building more
applications easier (a la Lotus Notes).

I am starting small, but it does not hurt to think big either.

Another reason to start small.
