A TAHG model based software generator system

Presents a timed attribute hypergraph grammar (TAHG) model-based software generator system. A TAHG model consists of a syntax definition, a semantic definition, and object definitions. In the syntax definition, a designer uses a parameterized context-free grammar, called a hypergraph grammar. In the semantic definition, the designer describes the dynamic behavior of target objects using a generalization of attribute grammars. In the object definitions, the designer describes views of objects and interactions with the user. Our TAHG-model based software generator allows us to produce an interactive software system, which can deal with graph-structure based 2D information processing systems such as Petri net editors, logic circuit editors and program chart editors
