The core methodology of Enterprise Engineering (EE) is Design and Engineering Methodology for Organisations (DEMO) and has been the subject of modelling tools. This methodology can be split into a method or process part and a notation part, describing the meta-model and its visualisation. The way the notation of the methodology has been described for these tools has been of different detail levels. This paper describes the DEMO notation using the grammar of the Simplified platform as an exercise towards a complete notation grammar that can describe all existing and possibly future notations and also to complete the DEMO notation specification. The grammar is part of the Simplified platform, and the notation is the published definition of the notation part of the DEMO methodology. We have chosen a practical approach to developing the notation script and thinking out-of-the-box by not creating a theoretical box a priori.
