Arabic Mathematical e-Documents

What problems do e-documents with mathematical expressions in an Arabic presentation present? In addition to the known difficulties of handling mathematical expressions based on Latin script on the Web, Arabic mathematical expressions flow from right to left and use specific symbols with a dynamic cursivity. How might we extend the capabilities of tools such as MathML in order to structure Arabic mathematical e-documents? Those are the questions this paper will deal with. It gives a brief description of some steps toward an extension of MathML to mathematics in Arabic exposition. In order to evaluate it, this extension has been implemented in Mozilla.
