Much of the usage of Moose and indirectly Mondrian/Roassal is related to software analysis.

However I want to use Rossal as the basis for a Computer Aided Design drawing application based on a predefined standardized model [1][2]. Part of me thinks that in line with keeping a separation of model and view, many/most of the classes of this model may require a matching parallel class for its graphical representation - perhaps one that inherits from ROShape or ROElement.

MyModelClass1>>shape ^ MyModelClass1Shape or... MyModelClass1>>shape ^ ROBox + ROCircle

...my thinking being that specifying "what should be drawn was a lite enough coupling to be reasonable, leaving the "how to draw it" defined elsewhere. However there are different types of diagrams with different representations of model elements, so perhaps with only a few diagram types I could just use a few selectors like MyModelClass1>>schematicDiagramShape and MyModelClass1>>wiringDiagramShape, or otherwise would require some class to maintain a mapping (DiagramType, ModelClass, Shape) There actually is an associated standard for Graphics Exchange [3] that I ultimately may align myself with, but not really worried about for now. Anyhow, not sure if you can make sense of any of that but any advice will be appreciated. cheers -ben [1] International Electrotechnical Commission IEC61970 Common Information Model for Power Systems [2] https://cimphony.com/cim-intro.pdf just have a quick look at Figs 3.9, 3.10., 3.13 [3] http://cimug.ucaiug.org/Meetings/Milan2010/Presentations/15%20IEC%2061970-4… _______________________________________________ Moose-dev mailing list Moose-dev(a)iam.unibe.ch https://www.iam.unibe.ch/mailman/listinfo/moose-dev
