One of the core research topics of WISE is conceptual modeling. During conceptual modeling, we create models for the system to be developed or for the domain under considerration without consideration implementation aspects. While in the past, the conceptual modeling techniques, such as ORM, UML or ER where very general and could be used for different domains, nowadays domain-specific modeling languages are preferred. These domain-specific modeling languages are tailored to their domain and provide first-class modeling concepts for concepts that are specific for the domain under consideration.
