To be able to precent classes I also need a working dictionary so I can make a reference to the original class. A first draft of the visual dictionary can be seen below. It is working well, with the exception that the “Data Model” folder get very large. The Functions folder will suffer the same, so I might need to add a grouping folder back – Diagram is exactly that. This is however minor as it is only visualization. In fact I am very happy with the Dictionary concept. What remains now is some additional code allowing us to specify that one class is only a precentation of a master object. Most aspects of the drawing engine is working very well, so I am not that far away from finally releasing a first version that only include the drawing/modelling engine.
The concept of precentation is that the model contain exactly one physical master object and that each diagram can make precentations of that master.
