The benefits of the technology are so far reaching that we feel the intended audience spans technical managers, developers and CTOs. In general the target audience includes researchers and practitioners who are working on complex problems related to the design and implementation of any complex domain and would like to understand the benefits of applying MDE techniques towards GSD and leverage existing tools and frameworks (i.e. Language Workbenches) to develop MDE solutions. The first half will be less technical than the second half where we cover the details of MDE and GSD in action in complete detail showing patterns and code. Attendees will come away with an appreciation for how they can effectively raise the level of abstraction in their domains without sacrificing the semantic rigor and precision needed for correct and robust systems.
