Software reuse approaches can be classified into two closely related cate-gories: development for reusable component and development with reusable component. System development withreusable components involves in a series of related woks: component representation, component retrieval, componentcomposition, component modification, etc. Because formal methods have rigorous theoretical foundations and cancharacterize computational semantics of a component, they has been intensively researched in software engineering do-main. This paper surveys the formal methods of component representation and retrieval, introduces current statusand outlines future trends.展开更多
