Hi everybody In order to give an overview of some of the issues involved in writing or displaying mathematical equations in Arabic, and some of the needed features in mathml, I've posted a 5 page introductory paper at http://www.rubicon.com.jo/papers/MathML-Arabic.pdf The intended audience for this paper is primarily those who are not familiar with the basic issues of writing mathematical equations in Arabic. We have been working on a partial solution to writing mathematical equation in Arabic within a consistent system. The best & most suitable system is of course mathml, but as everybody knows, this lacks the specs for right-to-left & non-latin based systems. Our approach to the problem is line with any typical xml based solutions: separate the information from the presentation, and deal with each separately. The information contained in the equation is "universal" in the sense that what the equation says is the same regardless of how one represents it. So whatever system needs to be developed or specified, it must be capable of storing & describing the equation. That is, the mathml description of the equation might need to be abstracted slightly. The presentation aspect of the equation is now language specific. In any ML based system, this would be the job of the xsl/xslt & the presentation software. Separating the info from the presentation, and possibly abstracting the info would also allow for "automatic" translation of equations into multi-languages on the fly. In the system we are envisioning, this would (or should) simply involve changing two to three attributes (like lang, dir, and map). The font issue, though important in any application, is secondary to the specs of the system. Regards, Isam. ====================================== Dr. Isam S. Ayoubi Managing Partner - Rubicon P.O.
