Cassiopeia is a scientific word-processing and symbolic-algebra system. It includes a MathML-based equation editor, a 2D graph module, a simulation module and exports to LaTeX and HTML. Cassiopeia stores its documents in a relational database management system and therefore allows multi-user access to a common document repository (co-editing in a workgroup).
