Résumé : A resurging interest in domain-specific languages (DSLs) has identified the benefits to be realized from customized languages that provide a high-level of abstraction for specifying a problem concept in a particular domain. Although there has been much success and interest reported by industry practitioners and academic researchers, there is much more work that is needed to enable further adoption of DSLs. The goal of this panel is to separate the hype from the true advantages that DSLs provide. The panel discussion will offer insight into the nature of DSL design, implementation, and application and summarize the collective experience of the panel in successful deployment of DSLs. As a counterpoint to the current benefits of DSLs, the panel will strive to provide a fair and balanced assessment of the current state of the art of DSLs by pointing to the existing limitations and future work that is needed to take the concept of DSLs to further heights. The assembled panelists are experts in the research and practice of DSLs and represent diverse views and backgrounds. The panel is made up of industrial researchers, commercial tool vendors, and academic researchers. The panelists have different perspectives on the technical concerns of DSLs; e.g., half of the panelists are proponents of textual DSLs and the other half has experience in graphical notations representing visual languages.
