Thanks!

Hi Aaron 

thanks for creating this list

here in Paris we are about to release a new version of UMCL, which will be available on sourceforge

i expect to release mid february and I'll attend the CSUN conference this year

hope to see you there

I'm glad to do this, of course!
Was the summary I put on the wiki correct?

Hopefully I'll be at CSUN too. It would be good to have a math get
together with whomever is there.

lamnda does not have any input. it's not actually a converter. they have their own code and a simple editor to use it. for the sighted they have a visual font displaying on the screen the braille characters in an easily understandable way (for the teacher), but as far as it is intended to receive documents in their own language
there is an offlien exporter allowing to see the formula in graphics via mathml though
 

Hopefully I'll be at CSUN too. It would be good to have a math get
together with whomever is there.

Are you sure it's not a converter?

The lambda FAQ at http://www.lambdaproject.org/default.asp?sec=109 says:
*Does the Lambda programme allow Braille printing of any print
mathematical text? And a mixed one, with text and formulas?
*Lambda will allow the printing of mathematical texts according to the
most popular European national codes and to the American Nemeth code.
The mixed texts will be dealt with separately: the mathematical part
will be analysed according to Lambda system, the textual one will be
printed, as any text editor does.

as well as

*Why designing a new system like Lambda to write Mathematics, when other
textual linear languages were available, like TeX and LaTeX?
*The Lambda system is based on the integration of a complete linear
code, that is compact and convertible through an editor, the blind
people can easily manage. Today, there are no systems for mathematical
writing able to suitably meet this requirements.
The code is directly tied to MathML, that is a recognised standard at
international level, then all the conversions among different formats
are guaranteed.

and

*Can a university student find a suitable and complete tool in the
Lambda programme, to attend a scientific faculty?
*The Lambda code is directly convertible (for input and output) into
MathML and, through this code, into TeX and LaTeX, that are the most
used mathematical formats in the university environment. The editor is
powerful and designed also for superior Mathematics and the user can
also enrich it by macros and scripts.
We may say actually there is no product able to supply blind university
students with a work environment so rich and effective, to manage
mathematical texts.

It sounds like Lambda is both a Braille code and an intermediate format
that can be changed into other representations of math. What am I missing?

Well actually the lambda code is a specific linear code which supports

several dictionnaries.  for each country they made a dictionary which 

uses, as far as possible, the same Braille symbols  than the offical national 

one. Nevertheless this is not the official national code because the grammar

of the code is different, it is the Lambda National code. One big difference 

is that lambda uses 8-dot Braille, and they also have a 6 dots braille 

projection but I think this can only be used to print and not to work in the 

software (this Im not 100% sure)

The linear code is XML based but it is not MathML. They have a converter

that exports to MathML on demand, to open the formula in another

window, in graphics. I think they use a IE window for that, with a plugin to 

render MathML.

There is also a MatML importer for their code so you can import a formula in

the software.

Maybe they have been developping more things recently

It would be interesting to find out, in any case. Certainly, if by
"American Nemeth code" they mean some kind of Lambda-Nemeth hybrid, then
perhaps they can edit the FAQ to make that clear.

Hello.
I've had the following info about Lambda from a friend of mine who
collaborated to the original project:
1) The license is of a commercial;
2) It is coded in C++
3) Input: MathML and writing the Lambda code (textual quote from my
friend)
4) The output does not include Nemeth.

I hope this may help.

Regards,
Valeria
