A pattern language model for framework development

Pattern language has long been paid attention for its intrinsic characters such as its domain-orientation, problem-orientation and solution-orientation. Much of domain knowledge has been captured in well established pattern language. This paper, based on an investigation and study on patterns and relation between them, proposes a pattern relation model, to formalize the semantic structure of a pattern language. We also utilize this model to facilitate the development of a framework, to show a concrete example of this useful model.
