Relational Grammars (RGs) are one of the higher-dimensional grammar formalisms that have been proposed for representing visual languages (VLs). This paper serves as an overview of the formalism as well as a case study of its application in a visual language interface (VLI) for process modeling. Relational Grammars are a member of the context-free family of Constraint Multiset Grammars (Marriott and Meyer this volume), and several subclasses of Relational Grammars have been proposed that have… CONTINUE READING
