PicoForms is the company I work for. Here I work with creating a MIDP XForms enabled browser for cell phones. It supports phones with very limitied capabilities, e.g. CLDC 1.0/MIDP 2.0.
I created the codebase for an XForms processor and released it under the
Mozilla Public License on sourceforge. The code
was written while I attempted to make a business out of it. At the moment
the code is laying still as I have no time to work on it.
I am and have in many years been a member of the XForms working group in
W3C. As a consequence of the time consuming
standardization process I created a small site where I could decscribe the
extensions in the XForms processors I created for Novell and others.
This is my friend's, Adam Williams, online symbolic calculator. It is similar to Matlab or Mathematic but webbased which makes it a lot more flexible for sharing.
