Abstract:
Graph-like modeling languages (GLML) are deployed in various domains. In model-based software engineering they are used directly or indirectly for the development of software. In different engineering systems, graph-like models are artifacts (circuit diagrams, energy flow diagrams) of the respective domain, which serve as input for downstream specialized applications (simulators, optimizers). When developing modeling tools, the concrete syntax of a language for creating, editing, and understanding models is immensely important. In order to develop tools with good usability, layout algorithms for the used languages have to be integrated. The development of these layout algorithms is particularly complex. With graph drawing there is a specialized field that deals with the development of layout algorithms for graphs. Some of these algorithms can be used for the layout of GLML or be adapted for GLML. In order to allow the reuse of layout algorithms and their assignment to a certain class
of GLML, a classification scheme for the concrete syntax for GLML is presented in this paper.
