Specifying Graph-like Diagrams with Dia Gne

AbstractThis extended abstract demonstrates that creating editors and environments for visual languages becomes considerably easier when restricting the class of visual languages. The presented approach considers graph-like languages whose diagrams consist of nodes and edges with different types. The specification method allows to describe such graphs in terms of their node and edge types and makes use of constraints in order to express syntactic properties. The DIA GEN system is used to generate running editors from such specifications
