I almost never hang out in the usenet news groups, but
I am glad that some people there are saying good things
about Axiom.

Let me make clear here that when you say "you have made some
things" and you refer to Axiom as "your system", that does
not refer personally to me. I presume you mean it collectively
in the sense of all the people who have contributed to Axiom
over it's long history. If there is any single person right
now to whom this might apply personally, then it would have
to be Tim Daly. I just happen to be one of the most vocal and
verbose supporters of Axiom at this time.
I hope other Axiom developers will also comment about
OpenMath and Singular.
The closest thing that the Axiom project has to "leadership"
is referred to as the Axiom Foundation. See
http://wiki.axiom-developer.org/AxiomFoundation
This is a group of three people (called "members") who have
agreed to help steer the project by being responsible for at
least some of the critical decisions and controlling any
financial support. Although I helped to set this up, I am not
one of the three members. Neither is Tim Daly (by his choice).
Either fortunately or unfortunately, depending on one's point
of view, the Axiom Foundation so far has had very little to
do. The idea is that membership in the Axiom Foundation would
rotate through those individuals most motivated to support
Axiom, but always consist of at least three people.

Now, MathAction (as opposed to Axiom) is something for which
I am largely responsible. :) I would be start to look into
adding a web interface to Singular on MathAction.

If you haven't already done this, I suggest you start by
reviewing references to openmath in the axiom-developer archives:
http://lists.nongnu.org/archive/cgi-bin/namazu.cgi?query=openmath&submit=Sea
rch%21&idxname=axiom-developer&max=10&result=normal&sort=date%3Aearly
For example:
http://lists.nongnu.org/archive/html/axiom-developer/2004-01/msg00035.html
http://lists.nongnu.org/archive/html/axiom-developer/2003-12/msg00030.html
http://lists.nongnu.org/archive/html/axiom-developer/2003-07/msg00000.html
http://lists.nongnu.org/archive/html/axiom-developer/2003-06/msg00078.html
http://lists.nongnu.org/archive/html/axiom-developer/2003-06/msg00069.html
http://lists.nongnu.org/archive/html/axiom-developer/2002-12/msg00003.html
and a few more ... :) Unfortunately as far as I know, none of this
discussion lead to any substantial work on resurrecting the OpenMath
work in the open source version of Axiom.

Ok, I will look at this.

Probably we need to start something similar for Axiom.

No problem.

As I understand it Python is a dynamically typed language. To
use the word "strong" seems a little miss-leading.
MathAction is based on software (Zope) written in Python. So
your work with Python in Singular might be some advantage.

First I need to understand it. :)

Thanks, I will look into this and probably ask you a lot
of questions later.
