Description
Ever since the introduction of computers into society, researchers have been trying to raise the abstraction level at which we build software programs. We are currently adopting an abstraction level based on graphical models instead of source code: MDE. MDE is the driving force for some recent modeling languages and approaches, such as OMG’s UML or Domain-Specific Modeling. All these approaches are founded on metamodeling: defining languages that represent a problem-domain. A key factor for the success of any approach is appropriate tool support. However, only recently have tool creators started considering metamodeling as an important issue in their list of concerns. In this paper, we evaluate a small set of MDE tools from the perspective of the metamodeling activity, focusing on both architectural and practical aspects. Then, using the results of this evaluation, we discuss open research issues for MDE-based software development tools.
