Grammar Maturity Model

The evolution of a software language (whether modelled by a grammar or a schema or a metamodel) is not limited to development of new versions and dialects. An important dimension of a software language evolution is maturing in the sense of improving the quality of its definition. In this paper, we present a maturity model used within the Grammar Zoo to assess and improve the quality of grammars in a broad sense (structural models) and give examples of activities possible for each level.
