To contribute to the analysis of tools that attempt to acquire a Computation Independent Model (CIM) from the domain system, the author explores the Integrated Domain Modeling toolset and explains how it automatically acquires a formal CIM from description of a business system in the form of textual business use cases. This paper recognizes the computation independent nature of a Topological Functioning Model and suggests it to be used as a CIM within a Model Driven Architecture. The author of this paper shares her experience of using the toolset and mentions several lessons learned during the usage process as well as her suggestions for improvements.
