We describe a characterization the three classical world views of event scheduling, activity scanning, and process interaction and discuss transformations among them. We believe that one advantage of each is to allow more concise model descriptions by allowing a model specifier to take advantage of contextual information. Automated transformation among world views is difficult due to a modeler's use of contextual information. We illustrate this by transforming and then simplifying a model representation creating a version, similar to what a programmer or modeler might generate.
