OpenXM (Open message eXchange protocol for Mathematics):

Welcome to the home page of OpenXM. Last update is October 27, 2001 JST. Japanese Page (experimental),

What is OpenXM? It is an infrastructure for mathematical communication. We propose standards for mathematical computation (OpenXM-RFC's). We will also support OpenMath . 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. Here is a quick tour of the OpenXM package: functions 1, functions 2, Efficient computation.
