OpenMath is a language for exchanging mathematical formulae across applications (such as computer algebra systems). From 2010 its importance has increased in that OpenMath Content Dictionaries were adopted as a foundation of the MathML 3 W3C recommendation, the standard for mathematical formulae on the Web.
The OpenMath Workshop is the annual meeting of the OpenMath Society.
though others related to OpenMath are certainly welcomed. For examples of contributions see the previous OpenMath workshops
Contributions can be either research papers, description of new Content Dictionaries, particularly ones that are suggested for formal review and adoption by the [OpenMath Society](http://www.openmath.org/society/), or standard enhancement proposals.
