OpenXM (Open message eXchange for Mathematics): It is an infrastructure for mathematical communication. We propose standards for mathematical computation (OpenXM-RFC’s). We will also support OpenMath which works for the standardization of mathematical data. The project is also making experiments to connect mathematical software systems each other on the infrastructure. We are providing packages of mathematical software systems supporting the OpenXM protocol. Please view screenshots of OpenXM packages. Here is a quick tour of the OpenXM package: functions 1, functions 2, Efficient computation.
