Metamodel Specialization for Graphical Language and Editor Definition

This paper is a further development of ideas presented by the authors in the previous papers on this topic. More concretely, in this paper three ideas have got a further development. First, the usage of metamodel specialization for graphical language and editor definition will be explained in a more detailed way. Second, a more general universal metamodel (UMM) will be offered, which covers a richer class of graphical languages. Third, the offered universal metamodel will enable a fluent transition from graphical language definition to their graphical editor definition, UMM for graphical tool definition will be a relatively slight extension of UMM for language definition. Finally, the paper presents also basic ideas for implementation of a graphical tool building platform based on the proposed metamodel specialization approach.
