Engaging End-Users in the Collaborative Development of Domain-Specic Modelling Languages

Abstract. Domain-Specic Modelling Languages (DSMLs) are high-level languages specially designed to perform tasks in a particular do-main. When developing DSMLs, the participation of end-users is nor-mally limited to providing domain knowledge and testing the resulting language prototypes. Language developers, which are perhaps not do-main experts, are therefore in control of the language development and evolution. This may cause misinterpretations which hamper the develop-ment process and the quality of the DSML. Thus, it would be benecial to promote a more active participation of end-users in the development process of DSMLs. While current DSML workbenches are mono-user and designed for technical experts, we present a process and tool support for the example-driven, collaborative construction of DSMLs in order to en-gage end-users in the creation of their own languages
