Abstract: In projection-based modeling environments, users work with views of the modelled system or enterprise that are generated dynamically, on demand, from a Single Underling Model (SUM). Moreover, they usually cannot change the SUM directly, but can only influence its contents indirectly via views. This means that at least some of the views need to be editable so that they can be used to evolve the SUM to a new state. However, this is not always possible when the transformations used to project SUM content into view content do not provide the information needed to unambiguously map view changes into SUM changes. Therefore, mechanisms are needed to identify and take appropriate measures to ensure that the integrity of the SUM is not comprised, and it is not updated in unintended ways, when insufficient information is available. This paper illuminates the basic nature of the problem, categorizes the different kinds of situations in which editing ambiguities can arise and discusses potential strategies for dealing with them. These techniques contribute to the creation of user-friendly, yet dependable, projection-based modeling environments.
